Gastric Bypass Reduces Risk of Coronart Artery Disease
Evidence is beginning to mount that gastric bypass surgery does reduce the risk of coronary artery disease.
As reported in the American Journal of cardiology, Dr. John Batsis and his colleagues at Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire reviewed six studies. While each study had its own basis for assessing risk, researchers found that gastric bypass reduced the risk for a future cardiovascular event anywhere from 8 percent to 79 percent, compared to not having the procedure.
Based on this data, the researchers were able to say that the chance of having a a heart attack, needing heart surgery or dying from heart disease fell from 7.0 percent to 3.5 percent after undergoing bariatric surgery. For people who did not have surgery, and tried to ameliorate risk through other means, the probability of major cardiovascular events only fell from 7.1 percent to 6.5 percent.
The researchers acknowledged that the figures are at best estimates and that more studies are required to better determine actual numbers of cardiac events.
