My 90-year-old father recently needed several stents installed, because his coronary arteries were 85–95% blocked. This came as a bit of a shock to the family, as we had thought his heart was in good shape (aside from needing a pacemaker). So I’ve been thinking a bit about my own risk of coronary vascular disease (CVD), especially since I have hereditary high cholesterol (from my Mom’s side of the family).
Like any modern academic, I turned to the web for more information. There are many calculators on the web for computing one’s risk of CVD, almost all claiming to be based on the Framingham study of heart health. Unfortunately, they disagree enormously (by a factor of 2) on what my risk is.
I used the following statistics for all site: age 62, male, cholesterol 161 mg/dL=4.16mmol/L, HDL 43 mg/dL=1.11mmol/L, triglycerides 90 mg/dL=1.016 mmol/L, BP134/83mmHg, height 5’11” (180cm), weight 163 lbs(74 kg), race white, no treatment for blood pressure, non-smoker, and no diabetes, though these numbers are not all from the same day, and I’m doubtful of the blood-pressure reading, as it was done with a cheap home cuff that I don’t believe handles my low heart rate well. (When I’ve had oscillometric and auditory measurements made at nearly the same time, the oscillometric ones have been substantially higher.)
I got the following risks of CVD in the next 10 years:
|https://www.framinghamheartstudy.org/risk-functions/cardiovascular-disease/10-year-risk.php#||10% (using lipids), 17.9% (using BMI)|
|http://www.cvriskcalculator.com/||10.1% (heart attack or stroke)|
|http://chd.bestsciencemedicine.com/calc2.html||15.4% (Framingham), 11.6% (Qrisk2), 10.3% (ACC/AHA ASCVD)|
|http://patient.info/doctor/cardiovascular-risk-calculator||12% (CHD), 5% (MI), 3% (CHD death), 3% (stroke), 18% (**CVD), 4% (**CVD death), 14% (JBS CVS Risk)|
I’ll have to ask my doctor whether it is worth getting a high-sensitivity C-Reactive Protein (hsCRP) test for inflammation to use one of the risk calculators that takes inflammation into account.
The risks are about normal for my age, but I’d like to reduce them if I can. I’m already on statins (and have been for 25 years) and 81mg aspirin (self-prescribed), I already get about 150 minutes a week of moderate exercise, and I’ve been controlling my weight (though I’ve put on 4 lbs in the past year that I’d like to get rid of). I’m not sure how much more I can reduce the risk.
