Although there is reasonable consensus that omega-3 FAs lower the risk of fatal end points, the association between these FAs and the risk of nonfatal cardiac events (ie, MI, unstable angina) remains less clear. Such a benefit was observed in JELIS [12••] but not in DART [7] or GISSI [10]. However, ...

Cardiac surgery



Cardiovascular (heart) surgery is surgery on the heart or great vessels performed by cardiac surgeons. Frequently, it is done to treat complications of ischemic heart disease (for example, coronary artery bypass grafting), correct congenital heart disease, or treat valvular heart disease from various causes including endocarditis, rheumatic heart disease and atherosclerosis. It also includes heart transplantation.
