Living right no guarantee against disease

- DR. KEITH ROACH Your Good Health

Dear Dr. Roach: I am 74 and in good health except for osteoporos­is. I’m five-foot-three and weigh 106 pounds, and have followed a plant-based diet for eight years. I take no medication­s, walk briskly daily and still work, but my calcium score was 640. What’s happening here?

D.H.

Regular exercise and a plantbased diet are very effective at reducing the risk of heart disease when combined with reduction of other risk factors, especially smoking and blood pressure, but also managing emotional stress, maintainin­g healthy relationsh­ips and sleeping well. In my opinion, these are the foundation of good health, and if everyone did so, there would be far less heart disease and cancer.

However, a good lifestyle by itself is not a guarantee against heart disease or cancer. When you are living a healthy life and develop a medical issue, it is time to get evaluation and perhaps treatment.

The high calcium score suggests that there are blockages in the arteries to your heart. While some experts would recommend treatment (such as a statin) at this point, based on your calcium score, others recommend further evaluation. A high calcium score does not necessaril­y equal blockages. It is much more likely, though, approximat­ely doubling your risk of a heart attack.

A risk score is available that uses a coronary calcium score to help predict risk of heart attack. You can calculate this at tinyurl.com/mesarisk. Using the informatio­n you gave me, your estimated risk of having a major heart event is 14%, which is far above the usual recommende­d threshold for prescribin­g a statin. I recommend medication therapy to a person like you, but you should, of course, continue your healthy lifestyle, which is helping you many other ways, whether or not you decide on a statin drug. In fact, if you had been eating a less healthy diet, I suspect you may already have had a heart attack.

Dear Dr. Roach: Prior to and on the day of my first Pfizer COVID vaccine in January, I had been taking etodolac (Lodine) for osteoarthr­itis. Following my first vaccine, I became concerned that the anti-inflammato­ry might

affect the vaccine’s effectiven­ess and searched in vain for informatio­n on this topic. I contacted my doctor about my concern. He suggested I stop taking the medication three days before and after the second vaccine, which I did.

Am I walking around with only partial protection as a result of the impact of having taken the anti-inflammato­ries at the time of the first injection? With millions of people suffering from arthritis, I have to believe that some of them would’ve been in the medical trials. I never feel really safe even though I’m totally vaccinated now.

R.K.

The reduction in effectiven­ess in a vaccine due to taking an anti-inflammato­ry or Tylenol prior to the vaccine is theoretica­l, and based only on antibody studies. The effect, if any, is likely to be small. The second vaccine causes the body to make a much larger number of antibodies. Your second dose was not affected by any possible reduction from anti-inflammato­ry arthritis medicine.

No vaccine is perfect, but the real-world data from the Pfizer and Moderna vaccines show exceptiona­l effectiven­ess. A few people have got COVID-19 following the vaccine, but far fewer than was expected, and only very few were so ill they required hospitaliz­ation.
