A day before my 47th birthday last month, I took the subway to Manhattan’s Upper East Side for a coronary artery calcium scan (CAC).

For those who haven’t entered the valley of middle age, a CAC is a specialized CT scan that looks for calcium deposits in the heart and its arteries. Unlike in your bones, having calcium in your coronary arteries is a bad thing, because it indicates the buildup of plaque comprised of cholesterol, fat, and other lovely things. The higher the calcium score, the more plaque that has built up — and with it, the higher the risk of heart disease and even heart attacks.

A couple of hours after the test, I received a ping on my phone. My CAC score was 7, which indicated the presence of a small amount of calcified plaque, which translates to a “low but non-zero cardiovascular risk.” Put another way, according to one calculator, it means an approximately 2.1 percent chance of a major adverse cardiovascular event over the next 10 years.

2.1 percent doesn’t sound high — it’s a little higher than the chance of pulling an ace of spades from a card deck — but when it comes to major adverse cardiovascular events, 2.1 percent is approximately 100 percent higher than I’d like. That’s how I found myself joining the tens of millions of Americans who are currently on statin drugs, which lower levels of LDL cholesterol (aka the “bad” cholesterol).

I didn’t really want to celebrate my birthday with a numerical reminder of my creeping........
