Non-hemodynamic mechanisms of body adaptation to anemia include increased oxygen extraction in tissues, mediated by increased 2,3-diphosphoglycerate levels. Mechanisms ...

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.
