Research has shown that despite having controlled cholesterol levels,
a build-up of calcium in the coronary arteries might contribute
to higher risks of having a heart attack.
A three-year follow-up on a study of people taking cholesterol-lowering
statins, who had a heart attack, revealed that they had a significant
amount of calcium in their coronary arteries than those who didn't
have a heart attack.
From these results experts concluded that people who had excess
calcium of the coronary artery didn't benefit from taking cholesterol-lowering
statins and were in a higher risk bracket for developing cardiovascular
related conditions. One expert claimed that while statins were effective
at reducing the risk of heart attacks, the rate of reducing the
risk of these events was 35 percent in the best-case scenario.
Study on Calcium Build-up and Statin Use
-
Out of the 495 participants with nearly the same LDL levels
and no symptoms, 41 experienced a heart attack in the follow-up
portion of the study
-
On the whole, the patients who had a heart attack were shown
to have a significant build-up of coronary artery calcium than
those who didn't have a heart attack
Experts theorized when excess calcium was present in individuals,
there was a 17-fold greater chance that they would have a heart
attack than in those with no evidence of calcium. Experts also concluded
that the two most definitive indicators of heart attack were LDL
levels and calcium build-up.
