The myth of mild coronary disease 19. January 2008 William Davis (27) I hear this comment from patients all the time:"They told me that I had only mild blockages and so I had nothing to worry about."That's one big lie. I guess I shouldn't call it a lie. Is it a lie when it comes from ignorance, arrogance, laziness, or greed?"Mild coronary disease" is usually a label applied to coronary atherosclerotic plaque that is insufficient to block flow. Thus, having a few 20%, 30%, or 40% blockages would be labeled "mild." No stents are (usually) implanted, no bypass surgery performed, and symptoms should not be attributable to the blockages. Thus, "mild." The problem is that "mild" blockages are no less likely to rupture, the eruptive process that resembles a little volcano spewing lava. Except it's not lava, but the internal contents of atherosclerotic plaque. When these internal contents of plaque gain contact with blood, the coagulation process is set in motion and the artery both clots and constricts. Chest pains and heart attack result. So, the essential point is not necessarily the amount of blood flow through the artery, but the presence of coronary atherosclerotic plaque. Just having plaque--any amount of plaque--sets the stage to permit plaque rupture. One thing is clear: The more plaque you have, the greater the risk for rupture. But the quantity of plaque cannot be measured by the "percent blockage." It is measured by the lengthwise extent of plaque, as well as the depth of plaque within the wall. Neither of these risk features for plaque rupture can be gauged by percent blockage. Coronary atherosclerosis is a diffuse process that involves much of the length of the artery. It is therefore folly to believe that a 15 mm long stent has addressed the disease. This is no more a solution than to replace the faucet in your kitchen in a house with rotting pipes from the basement up. The message: ANY amount of coronary plaque is reason to engage in a program of prevention--prevention of plaque rupture, prevention of further plaque growth, perhaps even regression (reversal). It is NOT a reason to be complacent and buy into the myth of "mild" coronary disease, the misguided notion that arises from ill-conceived procedural heart disease solutions. Image courtesy Wikipedia.

Red flags for lipoprotein(a) 17. January 2008 William Davis (24) Lipoprotein(a), Lp(a), is an important cause for heart disease, heart attack, and coronary atherosclerotic plaque. How do you know you have it?Of course, it could be as simple as checking a blood level. But there are also a number of red flags for the presence of Lp(a), tell-tale signs that suggest it is present and contributing to the growth of coronary plaque. I've seen so much of this pattern over the years that it's gotten so that I can pretty much pick out most of the people with Lp(a) just by either looking at them or by hearing their story. I do this simply by knowing what hints to look for.Some of the red flags for Lp(a) include:--High blood pressure in a slender person. Overweight is the overwhelmingly common reason for high blood pressure. However, inappropriate high blood pressure in a slender person can serve to tip you off that Lp(a) is present. --HIgh LDL cholesterol poorly responsive to statin drugs. For instance, someone's LDL cholesterol of 190 mg/dl will be treated with Lipitor 40 mg, but drops to only 165 mg/dl, a very poor response. This can sometimes point towards Lp(a). --Family clustering of heart disease in people before age 60. For instance, father with heart attack age 53, uncle with heart attack at age 55, aunt with heart attack age 59, etc. This clustering of risk, more often than not, signals Lp(a). --Coronary disease or high heart scan score in the presence of relatively bland appearing lipids. For instance, LDL cholesterol 130 mg/dl, HDL 55 mg/dl, triglycerides 70 mg/dl on no medications or other efforts--figures ordinarily not associated with high likelihood of heart disease--yet heart disease is indeed present. This can mean that Lp(a) is the concealed culprit behind coronary atherosclerosis. These red flags are not perfect. If you lack any of them, it doesn't necessarily rule out the possbility of having Lp(a). They simply serve as signs to suggest that Lp(a) may be lurking.Once Lp(a) is identified, then the battle begins to gain control over this somewhat troublesome genetic pattern. Resourcesfulness and some ingenuity may be required. However, knowing that you have it shows you where to concentrate your efforts.
Vytorin study explodes--But what's the real story? 15. January 2008 William Davis (28) The makers of Vytorin, Merck/Schering-Plough Pharmaceuticals, issued a press release about the the Enhance Study yesterday. The news has triggered a media frenzy. The NY Times reporting of the story:Drug Has No Benefit in Trial, Makers SayThe 700 participants in the trial all had a condition called "heterozygous hypercholesterolemia," a genetic disorder that permits very high LDL cholesterols. The average LDL at the start was 318 mg/dl.The Times reported that, while Vytorin cut "LDL levels by 58 percent, compared to a 41 percent reduction with simvastatin alone," but "the average thickness of the carotid artery plaque increased by 0.0111 of a millimeter in patients taking Vytorin, compared to an increase of 0.0058 of a millimeter in those taking only simvastatin." There was no difference in heart attacks or other "events" between the two groups. (Vytorin is the combination of simvastatin and Zetia.) In other words, the participants taking Vytorin had 53 ten-thousands of a millimeter more plaque growth than the group taking just simvastatin.I am always uncomfortable when put in the position of defending a drug or drug company. However, it is patently absurd that this study has generated such attention. I suspect the public and media are waiting for another Vioxx-like debacle, with memories of concealed or suppressed data that suggested heightened heart attack risk that was dismisssed by the drug manufacturer. (That's not to say that the company hasn't been trying to delay or modify the outcome of the study, which they apparently have, much to the objections of the FDA.) However, at this point, there is no reason to believe that this question possesses any parallels to the Vioxx fiasco. If we accept the data as reported, however, we might say it calls the entire "Lipid Hypothesis" into question: If LDL cholesterol is significantly reduced but is not correlated with reduction in plaque, is LDL the means by which atherosclerotic plaque progresses? This trial does not answer that question, but does serve to raise some doubt. Another issue: Heterozygous hypercholesterolemia, and thereby LDL cholesterol, may not be the overwhelming driver of plaque growth in this population. It is probably the number of small LDL particles, a factor which is not revealed by LDL cholesterol. For this reason, heterozygous hypercholesterolemia by itself is insufficient to cause heart disease. Some other factor(s) needs to be present. I would propose that it is the size of the LDL particle: When small, heart disease develops; when large, heart disease is less likely to develop. This issue was not addressed by this study. Readers of The Heart Scan Blog know that conventional LDL cholesterol, the number used in this study, is a virtually worthless number for truly gauging plaque behavior because of its flagrant inaccuracy. So, there are substantial uncertainties, contrary to the absolute certainty expressed by people like Dr. Steve Nissen (who, by the way, has no expertise in lipoprotein disorders). It is premature to reach any firm conclusions from this study. The only conclusions that I personally come to are 1) Is this yet another reason to question the entire Lipid Hypothesis as it stands? and 2) What would the results have been had LDL particle number and LDL particle size been examined, not just LDL? I would not automatically conclude that Zetia causes carotid plaque. This is absurd. And I am definitely not one to come to the rescue of a drug or drug manufacturer. I am simply after understanding and truth. As an interesting aside, Dr. Howard Hodis of the University of Southern California and an expert in carotid scanning for heart disease prevention research, made a comment relevant to us in the Track Your Plaque program: "Clearly, progression of atherosclerosis is the only way you get events,” Dr. Hodis said. “If you don’t treat progression, then you get events."
Dr. Arthur Agatston in the news 15. January 2008 William Davis (7) The Miami Herald has a new report on Dr. Arthur Agagtston (of South Beach Diet fame) to announce his new book, The South Beach Heart Health Revolution:The South Beach Diet doctor takes on cardio careAgatston, the granddaddy of CT heart scanning, is always at least worth listening to. Although his diet may not be perfect, it clearly has jumped light years ahead of conventional diets like the inane American Heart Association diet. The South Beach Diet focuses on healthy oils, nuts, lean meats, vegetables, and fruits, while slashing grains (except in the often disastrous phase III). The article lists Dr. Agatston's advice to achieve a "heart healthy" lifestyle:• Maintain a healthy weight through diet.• Undergo CT heart scans to check for arterial plaque.• Do aerobic exercise, along with stretching and strengthening workouts.• Ask your doctor about taking statins and other cholesterol-lowering drugs. We wouldn't have CT heart scan scoring (at least in its present form) without Dr. Agatston, who developed the algorithm for scoring years ago in the early days of heart scanning. We also need to credit him with putting together a rational diet despite the counter-information emanating from the Heart Association, the USDA (a la Food Pyramid, the one that makes Americans fat and diabetic), and the American Diabetes Association, among others. But "Ask your doctor about taking statins and other cholesterol-lowering drugs"? This is where Dr. Agatston begins to falter. While he is putting his enormous notoriety to use, his message is bland and ineffective. "Do aerobic exercise"? We don't need Dr. Agatston to tell us this. As much as Art Agatston has added to the national conversation on heart disease and diet, he has failed to deliver the message of true heart disease prevention. His approach lacks just a few crucial ingredients like lipoprotein testing, diagnosis of hidden causes of heart disease (like Lp(a)), and vitamin D. (Two years ago I had a patient I saw for an opinion after he'd showed Dr. Agatston his lipoprotein panel. The patient said Dr. Agatston looked at the report and didn't know what to do with it and handed it back to him without comment. He then asked if he wanted his autograph.)Anyway, the rising tide raises all boats. Agatston's repeated public endorsements of heart scans will help deliver the message that heart disease is detectable in its early stages and should trigger action to follow a heart disease prevention program. That alone is an accomplishment in a world hell-bent on dragging us into the hospital for procedures.
Take this survey: I DOUBLE-DARE YOU 14. January 2008 William Davis (10) In a previous post I entitled Heart disease reversal a big "No No", I posed a challenge--a dare--to readers to ask their doctors if coronary heart could be reversed. Here's what I said:I dare you: Ask your doctor whether coronary heart disease can be reversed.My prediction is that the answer will be a flat "NO." Or, something like "rarely, in extraordinary cases," kind of like spontaneous cure of cancer.There are indeed discussions that have developed over the years in the conventional scientific and medical literature about reversal of heart disease, like Dean Ornish's Lifestyle Heart Trial, the REVERSAL Trial of atorvastatin (Lipitor) and the ASTEROID Trial of rosuvastatin (Crestor). Reversal of atherosclerotic plaque in these trials tends to be small in scale and sporadic.The concept of reversal of heart disease has simply not gained a foothold in the lexicon nor in the thinking of practicing physicians. Heart disease is a relentlessly, unavoidably, and helplessly progressive disease in their way of thinking. Perhaps we can reduce the likelihood of cardiovascular events like heart attack and death with statin drugs and beta blockers. But reverse heart disease? In your dreams!We need to change this mentality. Heart disease is a reversible phenomenon. Atherosclerosis in other territories like the carotid arteries is also a reversible pheneomenon. Rather than throwing medicines and (ineffective) diets at you (like the ridiculous American Heart Association program), what if your doctor set out from the start not just to reduce events, but to purposefully reduce your heart's plaque? While it might not succeed in everyone, it would certainly change the focus dramatically. Toggle navigation Home Blog Home Archive Join Now Log in Is it mainstream or alternative? 24. May 2006 William Davis (0) A question I get about once a week: "Is your program a kind of alternative medicine?"Our program for control and reversal of coronary plaque using CT heart scans applies an eclectic panel of tools to achieve its goals. We use high-tech methods like lipoprotein analysis and CT heart scans; nutritional supplements like fish oil, vitamin D, and l-arginine; diet strategies and "functional foods" (using foods as a therapeutic tool); and conventional medication. I don't consider this approach "alternative" in the sense that it uses unmeasurable or spiritual strategies. But I don't consider it mainstream, either, since current mainstream practice of heart disease prevention is far less rigorous with far less satisfactory results. I think I can sum up the Track Your Plaque approach by saying that we use tools that work. Our measure of success is whether or not your heart scan score is stopped or reduced--that's hard to fudge. You can call it what you will, but I call it the best program for heart disease prevention I know of, alternative or mainstream. Want to see someone turn diabetic? 24. May 2006 William Davis (0) If you want to witness the transformation of someone into a pre-diabetic or diabetic, put them on a low fat diet. Dr. Dean Ornish's program, detailed in his books, Dr. Dean Ornish's Program for Reversal of Heart Disease and Eat More, Weigh Less , are woefully outdated in 2006. Yet the low fat notion continues to show up in the consciousness of people I talk to about heart disease reversal."I'm already on a low fat diet. Do you think my heart scan score has reversed?"Highly unlikely. What Dr. Ornish (as a non-cardiologist, by the way) failed to recognize is that what he did manage to reverse in a small number of people is something called "endothelial dysfunction", but he did not reverse or shrink coronary plaque. Given the limitations of technology when the Ornish concept got its start, it appeared as if reversal was obtained. In reality, all his approach accomplished was a relaxation in tone of abnormally constricted arteries, thus giving the appearance of reversal. Increased artery tone, or endothelial dysfunction, is extremely common when atherosclerotic plaque is present.Any cardiologist will tell you that there are many ways to reverse endothelial dysfunction: exercise, weight loss, cholesterol drugs, drugs for high blood pressure, fish oil, hormonal therapy, vitamin C, l-arginine, etc. There is nothing special about a low fat diet.In fact, Track Your Plaque followers will recognize that a low fat diet is, in fact, potentially harmful, particularly when low HDL or small LDL is part of your pattern.Let's bury the outdated ideas of the Ornish low fat diet once and for all. It doesn't work. All it may do is confuse you and set you back from your real coronary plaque reversal program. Inulin: A fiber for weight loss 23. May 2006 William Davis (10) Here's an interesting product that seems to be gaining some popularity for weight loss: Inulin.Not to be confused with "insulin", with which it is completely unrelated, inulin is a naturally-occurring plant fiber. It's found in broccoli, asparagus, celery, etc. Like beta-glucan from oats or pectin, inulin is a so-called soluble fiber, a fiber that assumes a gel-like consistency when exposed to water.Inulin has the effect of increasing satiety, or the sensation of fullness. This cuts your craving for foods. I've tried it recently and I prefer it over glucomannan, another soluble fiber for satiety. The people at Stonyfield Farms have been adding inulin to their yogurts from some time. The nutritionist at the company tells me that there's 2-3 grams of inulin per 6 ounce container of their yogurt. You can also find inulin as a supplement that you can add to foods, available from some health food stores and online supplement companies. I came across a neat product called Fiber Choice that's now being distributed widely throughout the U.S. I tried their Weight Management version. It was a delicous strawberry taste. The label says take two chewable tablets twice a day, but I found that two tablets three times a day somewhat better. It's best taken around 30-60 minutes prior to each meal and it causes you to be fuller with less food. One caution: It'll cause loads of gas, especially in the beginning. For that reason, you might try starting with a smaller dose, or start on the weekends when you have the option of some privacy! More info on the Fiber Choice product can be found at their website, http://www.fiberchoice.com. Disclaimer: I have no relationship with the manufacturer of this product. I'm simply passing on some thoughts on my experience with this interesting possibility for weight loss. Will you recognize the truth when you see it? 23. May 2006 William Davis (0) Do you ever wonder that, if the truth were given to you, that you'd recognize it as such? Or would you dismiss it as just another bunch of nonsense? After all, you and I live in the Information Age. It means that we have access to mountains of information like never before in human history. But it also means that the truth is often drowned out by an avalanche of mis-truths, sales pitches and marketing, and just plain nonsense. This struck me the other day when I was talking to a patient. 64 years old with a high heart scan score placing her at significant risk, she looked confused. I'd just described the multitude of causes of coronary plaque that we'd uncovered. The heart scan alone had been a shocker. "I don't understand. My doctor told me that I had nothing to worry about. I've known him for years and he knows me really well. He did a stress test. That was fine. I don't get all this other stuff you're telling me--lipoprotein whatever..."Despite my efforts to help her gain an understanding of our intensive approach, she just became increasingly more frustrated. "I just don't think I can do this."That's the last I've heard from her. As far as I know, she's returned to the comfort of her family doctor who has reassured her over the years. And perhaps there's some good in that. But I do fear for the day when, unexpectedly, she suffers some catastrophe that we told her was coming sooner or later unless real preventive efforts were started. You could say that she failed to recognize the truth when it was given to her-- boldly, unadorned, and with far greater scientific certainty than the casual reassurances she was accustomed to. But, unfortunately, that's all that some people want. Don't neglect the basics in your heart disease reversal program 23. May 2006 William Davis (0) Carl loved new ideas and novel approaches. You could tell by the sheer number of nutritional supplements he took. His list had grown to 18 different supplements over the past two years. Carl came to me for coronary plaque regression. Lipoprotein analysis did uncover several previously unsuspected abnormalties, most notably small LDL particles and lipoprotein(a). In addition, Carl's LDL cholesterol ranged between 111 mg-156 mg and he was clearly hypertensive, with systolic blood pressures consistently around 150-160. (Recall that people with Lp(a) are more prone to hypertension.) Carl was more than willing to have his lipoprotein(a) reduced. We did so with niacin and testosterone and the level dropped to near zero. Likewise, we corrected his small LDL pattern with niacin, fish oil, and a reduction in processed carbohydrates. But Carl really resisted doing much about his LDL cholesterol and high blood pressure. I got the sense that these "boring" issues simply didn't interest him. After all, LDL cholesterol and blood pressure were the stuff of TV commercials and the popular conversation propagated by drug companies. Carl's follow-up heart scan, however, finally persuaded him: a 24% increase in one year, likely due to the neglect of the basic issues. I liken Carl's case to being like the teenager with a new car who polishes the paint to a bright finish, puts new wheels and tires on it, spruces up the interior with various doodads--but then fails to change the oil. Sometimes it's the most basic issues that can diminish your success.Issues like LDL cholesterol and high blood pressure aren't the most glamorous, but they do count in your coronary plaque control program. Is your doctor a hospital employee? 21. May 2006 William Davis (0) There's a disturbing trend that's growing--silently but rapidly.In Milwaukee, three hospital systems compete for the local health care dollar. To gain more control over revenues and the routing of patients, the hospitals are aggressively hiring physicians to work for them. I've witnessed many of my cardiology colleagues, primary care doctors, and a substantial number of procedural specialists enticed by the offers made by hospital employers. This phenomenon is not unique to Milwaukee but is being used in many, perhaps most, major cities in the U.S. This means that physicians are employees of the hospital. That way, employee-physicians are obliged to use only the hospital system that employs them. In the old days, your doctor could use any hospital he/she desired, depending on the quality, location, facilities, etc. Now, many physician-employees are given no choice but to use the hospital that pays their salary. That by itself is not necessarily bad. But combine salary with incentives for bringing in patients for hospitalization and procedures--that the rub. In other words, physician-employees are incentivized to generate more revenue for the system, just as employees in many other industries. If you're a salesman for an insurance company, your job is to bring in more business. If you're a worker on an auto production line, you're expected to meet certain quotas. These same principles are now being applied to many physicians.How does this affect you? Well, if your physician--especially procedure-driven specialists like cardiologists, general surgeons, orthopedists, etc.--is a hospital employee, BEWARE! Do you really need that procedure, or is your doctor suggesting you have a procedure because it will add to his track record? Prevention? In this model of health care, why bother? It certainly doesn't pay for a hospital to keep you well. Then why should your physician-employee? Be careful who you're dealing with. If your physician is a hospital-employee, don't bet on getting preventive care. It's more likely you're that just a future source of revenue when it's time for your bypass operation, hip replacement, carotid endarterectomy, etc. What more powerful argument is there for increased self-empowerment and information for health care consumers? Take a walking vacation 20. May 2006 William Davis (1) If you're planning a vacation, why not consider a walking vacation?The concept is really taking off. All you need is a pair of comfortable shoes and an interesting locale. More and more services are popping up to help you plan fun and interesting destinations and itineraries. One such catalog can be found at http://walking.about.com/od/tours/a/walkingvacation_3.htmLengthier walks may require some advance planning and toting some supplies. Don't forget the water!From a health viewpoint, a walking vacation sure beats the heck out of a cruise that packs on 12 pounds of extra weight from the 24-hour a day buffet. If you're in the midst of a weight loss effort, several hours of walking through interesting locales and scenery can make it effortless. There's loads of neat places to visit from a walker's perspective. One interesting website is www.waterfallwalks.com that lists trails that provide spectacular views of waterfalls.Another variation on this theme is biking vacations. My wife and I are trying to set the time aside for a biking tour of wineries in the French countryside. That's our kind of multi-tasking! "Expanded indications for implantable defibrillators" 19. May 2006 William Davis (0) So reads the headline on a magazine I received recently (along with thousands of my colleagues) from a major hospital system.It goes on to say: "In January 2005, indications for implantable cardioverter-defibrillators (ICDs) were substantially broadened [emphasis ours] to include most patients with a left ventricular ejection fraction (EF) of 35% or less. This change translates into a 2- to 3-fold increase in the number of Medicare beneficiariries eligible for ICDs."Ka-ching!!! Hear the money piling up in the bank?The device manufacturers are constantly churning data and lobbying for reimbursement to expand the use of their devices to more and more people. Defibrillators in particularly are generally a $25,000 to $50,000 opportunity for the device manufacturer alone, not counting the costs incurred at the hospital for implantation. Beware. As reimbursement for stents and other procedures diminishes, expect a sudden "demand" for more and more people to get implantable defibrillators. Better yet, stay away from the whole issue by preventing your heart attack. Get a heart scan--but then don't delay taking action! 19. May 2006 William Davis (2) I just came from one of the local hospitals after having performed a heart catheterization on a patient I met earlier this week. Jack had gotten a heart scan a year ago with a score of 246, placing him in the 76th percentile. The "event" rate with this percentile rank is around 3% per year--not very high but enough to pose risk over a long period. Jack chose to ignore his score. After all, the pressures of work at the University, maintaining his home and yard, etc. consumed all his energies. He came to my office--now one year after his scan--and told me about the chest pressure he was getting. Initially, his chest pains occurred with extended walking. In the past week, however, Jack was experiencing chest pressure with just walking 30 feet. This pattern of increasing symptoms is called "accelerated angina", meaning that Jack was rapidly heading towards a heart attack. So I advised a heart catheterization in near future. Jack's catheterization showed extensive plaque including a 50% blockage in the mainstem artery and 90% in the artery to the front of the heart (left anterior descending artery). Jack is going to have a bypass operation tomorrow. What if Jack hadn't ignored his heart scan from a year ago? Well, I'd be very confident in saying that he would not be undergoing bypass surgery tomorrow.The lesson: Don't dilly-dally on taking action to keep your plaque from growing. While it's not an emergency, it can easily become one if you choose to ignore your scan. Feel that nudge in your back? 17. May 2006 William Davis (0) You feel that nudge in your back? That's your local hospitals competing for your bypass surgery business. Just this morning while watching a morning news show, I saw three advertisements for hospital bypass surgery programs. One ad featured a man in his 50s telling his story:"The cardiologist determined immediately that I needed a triple bypass operation. My family and I are very grateful to _____ hospital!"In what other field is failure celebrated so prominently? When I see these ads, I hear "My doctors failed to provide early detection and then prevent what became a life-threatening condition, even though heart disease is a chronic process that requires decades to develop." What if our man said instead,"I had a heart scan and my score was high. So I was shown why I had so much plaque. They then showed me how to control and even reduce the amount of plaque I had. I'm living safely and symptom-free without need for surgery or procedures."Of course, the hospital is out $60,000-100,000 for the surgery. How else could they afford ad campaigns costing several million dollars a year? See these advertisements for what they are: Marketing generated by profit-seeking businesses competing for your dollars--lots of them. << Older posts Newer posts >> Newer posts12...115116117118119120121122123124Older posts

But I do fear for the day when, unexpectedly, she suffers some catastrophe that we told her was coming sooner or later unless real preventive efforts were started. You could say that she failed to recognize the truth when it was given to her-- boldly, unadorned, and with far greater scientific certainty than the casual reassurances she was accustomed to. But, unfortunately, that's all that some people want.
Don't neglect the basics in your heart disease reversal program 23. May 2006 William Davis (0) Carl loved new ideas and novel approaches. You could tell by the sheer number of nutritional supplements he took. His list had grown to 18 different supplements over the past two years. Carl came to me for coronary plaque regression. Lipoprotein analysis did uncover several previously unsuspected abnormalties, most notably small LDL particles and lipoprotein(a). In addition, Carl's LDL cholesterol ranged between 111 mg-156 mg and he was clearly hypertensive, with systolic blood pressures consistently around 150-160. (Recall that people with Lp(a) are more prone to hypertension.) Carl was more than willing to have his lipoprotein(a) reduced. We did so with niacin and testosterone and the level dropped to near zero. Likewise, we corrected his small LDL pattern with niacin, fish oil, and a reduction in processed carbohydrates. But Carl really resisted doing much about his LDL cholesterol and high blood pressure. I got the sense that these "boring" issues simply didn't interest him. After all, LDL cholesterol and blood pressure were the stuff of TV commercials and the popular conversation propagated by drug companies. Carl's follow-up heart scan, however, finally persuaded him: a 24% increase in one year, likely due to the neglect of the basic issues. I liken Carl's case to being like the teenager with a new car who polishes the paint to a bright finish, puts new wheels and tires on it, spruces up the interior with various doodads--but then fails to change the oil. Sometimes it's the most basic issues that can diminish your success.Issues like LDL cholesterol and high blood pressure aren't the most glamorous, but they do count in your coronary plaque control program.
Is your doctor a hospital employee? 21. May 2006 William Davis (0) There's a disturbing trend that's growing--silently but rapidly.In Milwaukee, three hospital systems compete for the local health care dollar. To gain more control over revenues and the routing of patients, the hospitals are aggressively hiring physicians to work for them. I've witnessed many of my cardiology colleagues, primary care doctors, and a substantial number of procedural specialists enticed by the offers made by hospital employers. This phenomenon is not unique to Milwaukee but is being used in many, perhaps most, major cities in the U.S. This means that physicians are employees of the hospital. That way, employee-physicians are obliged to use only the hospital system that employs them. In the old days, your doctor could use any hospital he/she desired, depending on the quality, location, facilities, etc. Now, many physician-employees are given no choice but to use the hospital that pays their salary. That by itself is not necessarily bad. But combine salary with incentives for bringing in patients for hospitalization and procedures--that the rub. In other words, physician-employees are incentivized to generate more revenue for the system, just as employees in many other industries. If you're a salesman for an insurance company, your job is to bring in more business. If you're a worker on an auto production line, you're expected to meet certain quotas. These same principles are now being applied to many physicians.How does this affect you? Well, if your physician--especially procedure-driven specialists like cardiologists, general surgeons, orthopedists, etc.--is a hospital employee, BEWARE! Do you really need that procedure, or is your doctor suggesting you have a procedure because it will add to his track record? Prevention? In this model of health care, why bother? It certainly doesn't pay for a hospital to keep you well. Then why should your physician-employee? Be careful who you're dealing with. If your physician is a hospital-employee, don't bet on getting preventive care. It's more likely you're that just a future source of revenue when it's time for your bypass operation, hip replacement, carotid endarterectomy, etc. What more powerful argument is there for increased self-empowerment and information for health care consumers?
Take a walking vacation 20. May 2006 William Davis (1) If you're planning a vacation, why not consider a walking vacation?The concept is really taking off. All you need is a pair of comfortable shoes and an interesting locale. More and more services are popping up to help you plan fun and interesting destinations and itineraries. One such catalog can be found at http://walking.about.com/od/tours/a/walkingvacation_3.htmLengthier walks may require some advance planning and toting some supplies. Don't forget the water!From a health viewpoint, a walking vacation sure beats the heck out of a cruise that packs on 12 pounds of extra weight from the 24-hour a day buffet. If you're in the midst of a weight loss effort, several hours of walking through interesting locales and scenery can make it effortless. There's loads of neat places to visit from a walker's perspective. One interesting website is www.waterfallwalks.com that lists trails that provide spectacular views of waterfalls.Another variation on this theme is biking vacations. My wife and I are trying to set the time aside for a biking tour of wineries in the French countryside. That's our kind of multi-tasking!
"Expanded indications for implantable defibrillators" 19. May 2006 William Davis (0) So reads the headline on a magazine I received recently (along with thousands of my colleagues) from a major hospital system.It goes on to say: "In January 2005, indications for implantable cardioverter-defibrillators (ICDs) were substantially broadened [emphasis ours] to include most patients with a left ventricular ejection fraction (EF) of 35% or less. This change translates into a 2- to 3-fold increase in the number of Medicare beneficiariries eligible for ICDs."Ka-ching!!! Hear the money piling up in the bank?The device manufacturers are constantly churning data and lobbying for reimbursement to expand the use of their devices to more and more people. Defibrillators in particularly are generally a $25,000 to $50,000 opportunity for the device manufacturer alone, not counting the costs incurred at the hospital for implantation. Beware. As reimbursement for stents and other procedures diminishes, expect a sudden "demand" for more and more people to get implantable defibrillators. Better yet, stay away from the whole issue by preventing your heart attack.
Get a heart scan--but then don't delay taking action! 19. May 2006 William Davis (2) I just came from one of the local hospitals after having performed a heart catheterization on a patient I met earlier this week. Jack had gotten a heart scan a year ago with a score of 246, placing him in the 76th percentile. The "event" rate with this percentile rank is around 3% per year--not very high but enough to pose risk over a long period. Jack chose to ignore his score. After all, the pressures of work at the University, maintaining his home and yard, etc. consumed all his energies. He came to my office--now one year after his scan--and told me about the chest pressure he was getting. Initially, his chest pains occurred with extended walking. In the past week, however, Jack was experiencing chest pressure with just walking 30 feet. This pattern of increasing symptoms is called "accelerated angina", meaning that Jack was rapidly heading towards a heart attack. So I advised a heart catheterization in near future. Jack's catheterization showed extensive plaque including a 50% blockage in the mainstem artery and 90% in the artery to the front of the heart (left anterior descending artery). Jack is going to have a bypass operation tomorrow. What if Jack hadn't ignored his heart scan from a year ago? Well, I'd be very confident in saying that he would not be undergoing bypass surgery tomorrow.The lesson: Don't dilly-dally on taking action to keep your plaque from growing. While it's not an emergency, it can easily become one if you choose to ignore your scan.
Feel that nudge in your back? 17. May 2006 William Davis (0) You feel that nudge in your back? That's your local hospitals competing for your bypass surgery business. Just this morning while watching a morning news show, I saw three advertisements for hospital bypass surgery programs. One ad featured a man in his 50s telling his story:"The cardiologist determined immediately that I needed a triple bypass operation. My family and I are very grateful to _____ hospital!"In what other field is failure celebrated so prominently? When I see these ads, I hear "My doctors failed to provide early detection and then prevent what became a life-threatening condition, even though heart disease is a chronic process that requires decades to develop." What if our man said instead,"I had a heart scan and my score was high. So I was shown why I had so much plaque. They then showed me how to control and even reduce the amount of plaque I had. I'm living safely and symptom-free without need for surgery or procedures."Of course, the hospital is out $60,000-100,000 for the surgery. How else could they afford ad campaigns costing several million dollars a year? See these advertisements for what they are: Marketing generated by profit-seeking businesses competing for your dollars--lots of them.
