Supplements and Coronary Calcification
Q: I am wholesome, however a CT scan of my coronary arteries revealed intensive calcium deposits, which my physician mentioned can set off a coronary heart assault. May the deposits have been attributable to the calcium dietary supplements I’ve taken?
A: There’s no convincing proof that the calcium you get from meals or dietary supplements will increase calcium deposits (calcification) in plaque in coronary arteries and different blood vessels.
Coronary calcification is a marker for elevated cardiovascular danger. Calcium is deposited in plaque as a part of the atherosclerosis course of, which is brought about largely by continual irritation in blood vessel partitions. The physique is excellent at regulating calcium within the blood (besides in folks with sure metabolic or kidney circumstances); calcium within the blood doesn’t merely construct up in artery partitions.
Although a number of research have prompt that calcium dietary supplements enhance the chance of coronary artery illness, most analysis has discovered that they don’t have an effect on arterial calcification or coronary danger. For example, in 2012 the long-running Framingham Offspring Research discovered that individuals who consumed probably the most calcium from meals plus dietary supplements (as a lot as three,000 milligrams a day) didn’t have extra coronary calcium. This has been confirmed by subsequent analysis.
It’s not recognized what steps can scale back arterial calcification—aside from the recommendation for decreasing atherosclerosis, comparable to intensive dietary adjustments and weight reduction.
By the best way, we don’t advocate routine screening for calcification, which is completed with particular CT scans, although some docs advise it. Such screening remains to be being debated as a result of it’s unclear how a lot data it supplies for predicting coronary heart illness past an analysis of ordinary danger components. However, if you’re at intermediate coronary danger and it’s unclear whether or not it’s best to begin statin remedy, screening for calcification might make it easier to and your physician determine
