a collection of heart conditions caused by an acutely blocked coronary artery, including myocardial infarction and unstable angina |
chest pain or pressure. Stable angina is experienced by patients with ischemic heart disease. Unstable angina is the mildest form of acute coronary syndrome caused by temporary blockages of coronary arteries |
slower than normal heart rate, usually considered lower than 60 beats per minute. Seldom symptomatic until heart rate decreases below 50 beats per minute |
a diagnostic and/or therapeutic procedure in which a catheter is inserted into the heart and used to administer a dye to visualize the coronary arteries. If blockages are present, stents may be inserted to open blocked arteries |
the ability of the cardiac muscle to undergo the changes needed to cause a contraction |
a graphic representation of the electrical activity of the heart. The device used for this test is an electrocardiograph |
a condition in which cardiac output is reduced to the point where the blood supply can no longer meet the metabolic demands of the body |
related to cardiac contractility. Positive inotropic effects result in increased contractility while negative ones produce decreased contractility |
