London: Vitamin D is very important for bone strength and helps maintain calcium and phosphate levels in the body. Now, a new study has found that vitamin D supplementation may help reduce the risk of cardiovascular events such as heart attack in people over the age of 60.
According to the study, which was recently published in the British Medical Journal, the study is the largest of its kind to date, and further research is needed, particularly in people who use statins or other heart disease drugs. are
Several observational studies have shown an association between vitamin D intake and the risk of heart disease, the scientists in the study said.
However, controlled trials have not shown any evidence that vitamin D protects against cardiovascular events. A controlled trial is a trial in which two groups are compared. One group is given a drug and the other group is given a placebo.
To address this uncertainty in the studies, Australian scientists decided to investigate changes in the rate of major cardiovascular events by giving monthly doses of vitamin D to older adults.
The trial ran from 2014 to 2020, in which 1,662 of 21,315 Australians aged 60 to 84 were given a 1,500 microgram vitamin D capsule, while another 10,653 were given a placebo at the beginning of each month for five years. went.
The researchers found that the vitamin D group had a 9 percent lower rate of major cardiovascular events than the placebo group. The vitamin D group had a 19 percent lower heart attack rate and an 11 percent lower rate of coronary revascularization. However, there was no difference in stroke rate between the two groups.
Scientists analyzed more than 20,000 people over the age of 60 and concluded that participants who took vitamin D supplements at the beginning of each month for five years had fewer major cardiovascular events. .
The scientists also said that more research is needed before making any recommendations regarding the effects of vitamin D on the heart.
