Calcium Supplements Could Increase Risk of Heart Attack


Calcium Supplements Increase heart disease riskSupplements of calcium, which is usually consumed by elder people with osteoporosis (bone loss), is associated with an increased risk of heart attack. This is the results of a study in the British Medical Journal published last July.

The result showed that reassessment is required for the role of calcium supplements in osteoporosis management. Calcium supplements are commonly prescribed for bone health, but the experiment has recently mentioned that these supplements can increase the risk of heart attack (myocardial infarction) and cardiovascular events in healthy older women.

The research was led by Dr Ian Reid, professor of medicine at the University of Auckland, New Zealand, and  his colleagues from the University of Aberdeen, UK, and from Dartmouth Medical School in the United States.

The international research team that analyzed results from 11 randomized controlled trials of calcium supplementation intake (without addition of vitamin D), involving 12 000 patients.

Researchers found that calcium supplementation is associated with about 30 percent increased risk of heart attacks. They also found that calcium intake increases the risk of stroke and death although this increased risk is smaller and insignificant.

Previous studies have shown that high intake of calicum does not increase cardiovascular risk.

They conclude, given the modest benefits of calcium supplements for bone density and prevent fractures, reassessment of the role of calcium supplements in osteoporosis management is required.
