The intake of calcium supplements is linked with high risk of stroke, angina, myocardial infarction, ischemic heart attack, and sudden death.

This study was carried out to determine the effect of calcium supplements on cardiovascular events, such as stroke, myocardial infarction, and sudden death. Researchers administered calcium supplements to 732 women and placebo to another group of 739 females, all post-menopausal. The stroke, angina, myocardial infarction, ischemic heart attack, and total mortality risks were assessed in all the subjects.

Researchers observed a higher incidence of myocardial infarction in the calcium group than in the placebo group. Increased stroke, angina, ischemic heart attack, and total mortality risks were also found in subjects given calcium supplements. The findings of this study show that the intake of calcium supplements is associated with the occurrence of adverse cardiovascular events, such as stroke, angina, myocardial infarction, ischemic heart attack, and sudden death.
