Heart Surgery News and Research

RSS

Heart surgery is done to correct problems with the heart. More than half a million heart surgeries are done each year in the United States for a variety of heart problems. Heart surgery is used to correct heart problems in children and adults. This article discusses heart surgeries for adults. For more information about heart surgeries for children, see the Diseases and Conditions Index articles on congenital heart defects, holes in the heart, and tetralogy of Fallot.

The most common type of heart surgery for adults is coronary artery bypass grafting (CABG). During CABG, surgeons use healthy arteries or veins taken from another part of the body to bypass (that is, go around) blocked arteries. CABG relieves chest pain and reduces the risk of heart attack.

Researcher explore why some patients recover quickly after surgery while others don't

Why do some patients recover quickly after surgery, while others don't? That is an important question when treating older frail patients suffering from aortic stenosis. Lead author Dae Hyun Kim, M.D., M.P.H., Sc.D., and principle investigator Director Lewis A. Lipsitz in the Marcus Institute for Aging Research at Hebrew SeniorLife explore this question in a paper published today in the Journal of the American Medical Association Internal Medicine.
