| Question | Answer |
|---|---|
| aneurysm | thinning and weakening of the walls of an artery causing bulging of the wall in the shape of a sack |
| arteriosclerosis | a chronic disease of the arteries of the circulatory system characterized by thickening and hardening of the arterial walls caused by atherosclerosis |
| atherosclerosis | focal thickening of the wall of an artery caused by infiltration of mixtures of fibrous and fatty plaque |
| classical angina | stable angina |
| claudication | pain or weakness of muscles |
| dyspnea | difficulty breathing |
| embolism | a sudden obstruction of a blood vessel caused by an insoluble substance in the blood |
| endogenous lipid transport | movement of lipid produced by the liver to other parts of the body |
| exogenous lipid transport | movement of lipid absorbed from the intestines to the liver |
| gangrene | tissue death due to ischemia |
| heart failure | failure of the heart to pump blood effectively, resulting in back pressure and congestion of tissues with body fluids |
| hypertension | high blood pressure |
| infarction | cell death due to loss of blood supply |
| ischemia | temporary lack of blood supply that deprives tissues of nutrients and oxygen |
| myocardial infarction | irreversible heart muscle damage and cell death usually called a heart attack |
| peripheral vascular disease | disorders of the circulatory system including the arteries, veins, or lymph ducts but excluding the heart |
| stable angina | reversible ischemic heart disease that produces chest pain |
| streptokinase | an enzyme produced by the streptococcus bacterium that dissolves blood clots |
| tissue plasminogen activator (TPA) | an enzyme produced by endothelial cells that binds specifically to fibrin and therefore dissolves only clots that are localized rather than throughout the systemic circulation |
| unstable angina | sudden more severe angina that lasts longer than stable angina and is associated with either coronary artery vasospasm or a transient thrombosis |
