Blood pressure with exercise

Here's a frequently neglected cause for an increasing CT heart scan score: High blood pressure with exercise. Let me explain.

Paul's blood pressure at rest, sitting in the office or on arising in the morning, or at other relatively peaceful moments: 110/75 to 130/80--all in the conventional normal range.

We put Paul on the treadmill for a stress test. At 10 mets of effort (on the protocol used, this means 3.4 mph treadmill speed at 14 degree incline), Paul's blood pressure skyrockets to 220/105. That's really high.

Now, blood pressure is expected to increase with exercise. If it doesn't rise, that's abnormal and may, in fact, be a sign of danger. Normally, blood pressure should rise gradually in a stepwise fashion with increasing levels of exercise. But any blood pressure exceeding 170/90 is clearly too high with exercise. (Not to be confused with high blood pressures not involving exercise.) A handful of studies have suggested that a "breakpoint" of 170/90 also predicts heightened risk of heart attack over a long period.)

I see this phenomenon frequently--normal blood pressure at rest, high with exercise. This also suggests that when Paul is stressed, upset, in traffic congestion, under pressure at work, etc., his blood pressure is high during those periods, as well. I wouldn't be surprised to see other phenomena of underappreciated high blood pressure, like abnormally thick heart muscle (left ventricular hypertrophy), an enlarged thoracic aorta (visible on your heart scan), left atrium, perhaps even an abnormal EKG or abnormal kidney function (evidenced by an elevated creatinine on a standard blood panel).

Unfortunately, the treatments that reduce blood pressure are "stupid," i.e., they have no appreciation for what you are doing and they reduce blood pressure all the time, whether or not you're stressed, exercising, or sleeping.

Blood pressure reduction should begin with weight loss, exercise, reduction of saturated fats and processed carbohydrates (esp. wheat), magnesium replacement, vitamin D replacement. Think about CoQ10. After this, blood pressure medication might be necessary.

The message: Watch out for the blood pressures when you have a stress test. Or, if you have a friend who is adept at getting blood pressures, get a blood pressure immediately upon ceasing exercise. It should be no higher than 170/90.

    Dr. Davis,
    Sorry, this isn't about high blood pressure and exercise.  Do you believe there is a connection between high blood pressure and tinnitus?  Also, do you think that there are any vitamins or minerals that could relieve tinnitus?

    I know very little about tinnitus. However, I have seen some people get relief with niacin (immediate-release).

    Dr. Davis:

    What's the significance of blood pressure that does NOT increase with exercise? I frequently experience a slight blood pressure drop, or a slight rise in systolic but a slight drop in diastolic, even with moderately vigorous exercise; my doctor doesn't think it's a concern (he's only worried about it being high, and I run 115/75 on average when just sitting around), and I haven't been able to find anything on my own. I'd like to know more about what conditions it can signal, and that I should therefore ask my doctor about specifically.

I frequently experience a slight blood pressure drop,High blood pressure cure supplement, natural herbal remedy to lower & control high blood pressure. Use Alistrol everyday to help maintain healthy circulation and support cardio-vascular health.

    Just chiming in on the enzyme called serrapeptase. I have the capsules and only use it when any of my dogs get bitten by a centipede. As soon as they come into the house squirming and licking the bitten paw, I give them one capsule and w/in a few minutes, they stop squirming and licking and fall asleep. So I think it works even if the stomach acid might destroy some of it. BTW, I used to take 1000 mgs of bromelain at night before bed and once when I was taking it regularly for about a week, I took a cholesterol lab test and my results came back showing a big decrease in my LDL and Total cholesterol numbers. The only change I could think of that might have caused the decrease was taking the bromelain.

    I have the same problem as Paul. Low/Good blood pressure while sitting around, but extremely high blood pressure after/during exercising, going up stairs, playing the trumpet, etc.

    Although I understand and agree with all of the natural remedies you listed for lowering blood pressure (exercise, lower carbs, etc), why do you recommend low saturated fat intake? Are there any sources/studies that indicate that saturated fat has a direct effect on BP, and if so, that it's a bad thing? And would these studies take into account other variables such as carbohydrates and trans fats?

    Any information you have would be GREATLY appreciated! Thanks.

    I can understand the weight loss, exercise, and reduction of carbs (although not just processed, IMO) as well as magnesium and Vitamin D supplementation, but why the lower saturated fat? If you're trying to link lower sat fat intake to weight loss, I'd have to ask for a good source of information before I would believe you. In my practical experience in weight loss, I have lost tons of weight even though lots of my calories came from fat, and fat is needed for energy.

    Wow, I thought that to get your high blood pressure is to rest for a while. When you are from a walk or something.
