Document Summary
Cardiovascular disease (cvd) : diseases of the heard & blood vessels; includes coronary artery disease, heart attack, stroke, heart failure. Atherosclerosis : form of cvd where the inner layers of artery walls are made thick & irregular by plaque deposits; arteries become narrowed, & blood supply is reduced. When significant, results in ischemia: inadequate blood flow due to construction/obstruction of artery (oxygen supply less than oxygen demand) Plaque : deposit of fatty & other substances on inner wall of an artery. Myocardial infarction (mi) : damage to, or death of, heart muscle, resulting from failure of coronary arteries to deliver enough blood to heart; aka heart attack. Stroke : occurs when blood supply to the brain is cut off. Pieces of plaque can break free, travel to the brain & block blood vessels that supply blood to the brain. Arrhythmia : change in normal pattern of heartbeat. Diagnosis: exercise stress test with electrocardiogram (ecg), echocardiogram, angiogram.
