The risk of death due to cardiovascular diseases is 22 times more in kidney patients taking calcium supplements to minimize phosphorus level, according to the latest study published in the journal of Lancet.
Calcium produces two types of effects such as;
- It is absorbed in the blood and hardens the blood vessels thus increased the risk of heart diseases.
- Compensate the levels of calcium by reducing phosphorus in the body.
“Doctors commonly prescribe calcium supplements to prevent elevated phosphate levels, which can damage the body, but a growing number of studies have shown calcium supplements may actually increase the risk of heart disease,” explains Dr. Sophie Jamal, a physician at Women’s College Hospital and an associate professor of medicine at the University of Toronto. “Our study validates these claims and, for the first time, shows the long-term consequences of taking calcium supplements can be dangerous for patients with kidney disease.”
During this study researchers evaluated the data of 11 randomized controlled studies which were conducted in 4,6000 patients. They concluded that death due to heart attack or stroke was more common in kidney patients who have used calcium supplements in comparison to those who have used other treatments such as sevelamer and lanthanum (devoid of calcium).
“Some researchers and physicians have been saying for years that kidney disease patients need to get off calcium, now we think our review shows there is much more solid evidence to argue for that change to clinical practice,” the study’s senior author Ross Tsuyuki from the University of Alberta’s faculty of medicine and dentistry.
“The findings of our study provides the best evidence as to what doctors should be prescribing their patients, but further research is necessary to help us understand how exactly calcium increases the risk of death, if non calcium-based treatments reduce the risk of death, and whether certain types of treatments may be more effective and beneficial than others,” says Dr. Jamal.
