Another Track Your Plaque success story!
Stress made him do it!

Ralph is lead engineer for an enormous highway reconstruction process that posed considerable design challenges. It also landed him in the center of a hot political controversy. One moment he’d field calls from on-site engineers and contractors, and the next he’d be answering tough questions from politicians, environmental groups, and concerned citizens. Sometimes, the stress was almost unbearable.

With a project that was expected to last five years, Ralph really started to worry about the effects of stress on his heart while living through the maelstrom of controversy. Ralph’s family’s history also gave him cause to worry: his father died without warning at age 43 of a heart attack; his brother died the same way at age 49. Ralph was sure he was walking a tightrope and that stress could topple him over anytime. His only reassurance was that his mother was still alive and well at age 80.

We advised Ralph to get a CT heart scan. His score: 74—at age 54, this placed him in the 53rd percentile compared to other men his age (heart attack risk 2% per year)—not enough to pose a near-term danger and probably very different from the scores his dad and brother might have had at a similar age. However, all the plaque in Ralph’s coronary arteries was located in the left main stem artery, the shared trunk of two coronaries, the left anterior descending (LAD) and circumflex. Though Ralph’s score was not impressively high, its location elevated it to greater significance: heart attack originating from this location is immediately fatal.

Through the Track Your Plaque approach, we identified the following abnormalities that caused Ralph’s left main stem atherosclerotic plaque:

• HDL cholesterol 34 mg/dl (TYP target ≤60 mg/dl)
• Small LDL particles (TYP target <10% of total LDL)
• Triglycerides 123 mg/dl (TYP target ≤60 mg/dl)
• Excess VLDL (TYP target: 0 mg/dl)
• Vitamin D 23 ng/ml (TYP target >50 ng/ml)

Ralph also showed high blood pressure of 150/102 and borderline elevated blood sugar of 108 mg/dl, consistent with features of the “metabolic syndrome”, or pre-diabetes (even though Ralph didn’t meet the conventional criterion of waist size of ≥50 inches).

With the new-found knowledge of his heart disease risk, Ralph felt empowered and motivated to tackle his plaque. By converting to the Track Your Plaque nutrition program (eliminating chips, breakfast cereals, and minimizing snacks; using foods that help correct lipid and lipoprotein patterns, etc.), along with a walking program six days a week, Ralph dropped 30 lbs in weight over 18 months. Along with treatments to fully correct his abnormal lipid/lipoprotein patterns, another heart scan yielded a score of 69—a modest reduction from his original 74.

Ralph did it: Seized hold of a potentially life-threatening disease and conquered it. Not only did Ralph reduce the amount of plaque in the crucial left main stem artery, he acquired new piece of mind. Now, if building a new highway was as easy!

When a heart scan is MORE than just a heart scan

CT heart scans provide exquisitely detailed images of the coronary arteries. But there’s other information provided by images of the chest that can yield insights into long-term health. Here’s a list of a few common issues that arise.

Hiatal hernia

Heart scans provide images of the chest. However, if the stomach—ordinarily in the abdominal cavity below the diaphragm—migrates up into the chest, you can actually see the stomach in the chest. If someone had a heart scan after breakfast or lunch, you’ll even see their meal in the stomach nestled within the chest!

Hiatal hernias can vary in size from small to large. Though not generally dangerous, they can be a substantial source of chest discomfort (sometimes doing an awfully good imitation of a heart attack), indigestion, gastresophageal reflux (stomach acid regurgitating up into the esophagus), and other digestive problems. Though it presents no real implications for your heart disease prevention program, if a hiatal hernia is identified on your heart scan, it should be discussed with your doctor, since it may be responsible for symptoms and digestive disorders.

Enlarged Aorta

If the aorta measures more than 4.0 cm in diameter, your heart scan report may contain a comment about “aortic enlargement”.

The aorta is the major artery of the body emerging from the top of the heart and branches into all other arteries of the body like the carotid arteries, the arteries to the arms and legs, abdominal organs, etc. Heart scans show the aorta emerging upward from the heart (ascending aorta) and the portion that curves and heads downward through the chest towards the abdomen (descending thoracic aorta). If high blood pressure is present for several years, the aorta may enlarge. A diameter >4.0 cm suggests that forces causing it to enlarge have been at work for many years.

Other causes of an enlarged aorta are factors that weaken the lining of its wall and make plaque grow, just like the plaque in your coronary arteries. These include high cholesterol, inflammation, lipoprotein(a), and homocysteine. Occasionally, the aorta may enlarge due to inherited disorders that weaken structural tissues of arteries (e.g., Marfan’s syndrome).

Two consequences can arise from an enlarged aorta: aneurysm and stroke. If the aorta reaches a diameter of ≥4.5 cm, it’s classified as an aneurysm. Surgical replacement is often recommended when the aorta reaches 5.5 cm, since the likelihood of rupture increases dramatically at this diameter. Aortic enlargement is usually, though not always, is accompanied by aortic plaque that increases stroke risk (see below).

Should your heart scan report mention an enlarged aorta, discuss this with your doctor and ask how you can prevent it from getting any larger and how risk of stroke can be reduced.

Aortic calcium

If calcium is seen in the aorta, your heart scan report may contain a comment about “aortic calcification “ that can be mild, moderate, or severe.

Just as calcium in the coronary arteries represents atherosclerotic plaque, the same holds true in the aorta. Calcium, and therefore plaque, often but not always occurs with aortic enlargement. Plaque in the aorta has a tendency to rupture, though it doesn’t cause heart attack when this happens, but causes stroke and “mini-stroke”: little bits of debris or blood clot break free and travel “upstream”, usually to one of the small arteries of the brain.

The steps you follow to control coronary plaque and heart attack risk also reduce risk for stroke from aortic plaque. You should discuss how aortic plaque impacts on your prevention program with your doctor. Many authorities suggest that calcified plaque in the aorta trigger prevention efforts just like calcified plaque in coronary arteries, and that lipid treatment should be intensified to prevent further plaque growth and diminish risk for stroke.

Aortic valve calcium

Controlling the flow of blood ejected from the heart and into the aorta is an ingenious piece of natural engineering called the aortic valve. Just like any valve in the plumbing of our home or car, the aortic valve serves a similar function: to allow the flow of blood in one direction and prevent it from flowing backward into the heart. Viewed end-on, the aortic valve looks like a pie cut in three pieces. The three slices, or leaflets, are anchored to the aorta, allowing each leaflet to open and close with each beat of the heart.

The aortic valve is subject to wear and tear, just like brake pads in your car and cartilage in your knees. As plaque material accumulates along the aortic valve leaflets, they become stiff. Aortic valve calcium seen on a CT heart scan may be described as mild, moderate, or severe. Moderate and severe levels may lead to a need for echocardiography, an easy ultrasound-based test that can precisely quantify severity of valve dysfunction.

It’s been recently appreciated that the factors that create plaque in coronaries and aorta may contribute to calcification of the aortic valve, as well. (Please note that aortic valve calcium is distinct from aortic calcium.) It is presently unclear, however, whether correction of causes of coronary plaque also helps reduce aortic valve calcium.

Mitral valve calcium

There are two varieties here: calcification of the mitral valve itself and calcification of the “frame” of the mitral valve, often called the “annulus”. Your heart scan report may read either “calcification of the mitral valve”, “mitral annular calcification”, or both.

Mitral valve calcium is uncommon nowadays, though in the early 1900s it was very common (though not uncovered by CT heart scans!) as a result of childhood rheumatic fever which inflamed the valve, causing it to stiffen and accumulate calcium over many years. If you have mitral valve calcium, your doctor will likely order an echocardiogram to determine how stiff or leaky the valve has become.

Calcium on the mitral valve annulus is an entirely different story. It is a common and generally harmless abnormality that rarely interferes with valve function. Many people in their 70s and 80s develop annular calcium without consequence. Some physicians feel that annular calcification increases risk of valve infection whenever germs enter the bloodstream, e.g., during dental work. This is rare but should be discussed with your doctor. Beyond this, mitral annular calcium is a generally benign phenomenon.

Lipids are snapshots in time; heart scans are cumulative

Let’s paint a picture. It's fictional, though a very real portrait of how things truly happen in life.

Michael is an unsuspecting 40-year old man. He has not undergone any testing: no heart scan, no lipids, no lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:

• LDL cholesterol 150 mg/dl
• HDL cholesterol 38 mg/dl
• Triglycerides 160 mg/dl
• Small LDL 70% of all LDL

With this panel at age 40, Michael’s heart scan score is 100. That's high for a 40-year old male.

Fast forward 10 years. Michael is now 50 years old. He prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins now show:

• LDL cholesterol 150 mg/dl
• HDL cholesterol 38 mg/dl
• Triglycerides 160 mg/dl
• Small LDL 70% of all LDL

Lipids and lipoproteins are, therefore, unchanged. (Some of you might correctly point out that simple aging causes some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.) Michael's heart scan score: 1380, or an approximate 30% annual increase in score. Since Michael didn't know about his score, he took no corrective/preventive action.

The point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they wouldn't tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time.

In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan.

Which measure do you think is a better gauge of heart attack risk?
