A poorly constructed study, published in Heart Journal, said that taking calcium supplements doubled the risk of heart attack.
Here are two links to articles that debunk that study:

The same thing happened in 2010 and 2011.
Those studies were also easily debunked.
Some of the articles that provide analysis of them can be viewed by clicking these links:

Good For Cardiovascular Health
In contrast to what the negative studies said, other studies have shown that calcium supplementation benefits the cardiovascular system.
For instance, one study published in the American Journal of Medicine showed that 1,000 mg daily calcium supplements taken over a one year period increased the women in the study's HDL (good) cholesterol levels by an average of 7 percent.
