Management of Patients With Coronary Vascular Disorders-Chapter 28
| Question | Answer |
|---|---|
| acute coronary syndrome (ACS): | signs and symptoms that indicate unstable angina or acute myocardial infarction |
| angina pectoris: | chest pain brought about by myocardial ischemia |
| atheroma: | fibrous cap composed of smooth muscle cells that forms over lipid deposits within arterial vessels and protrudes into the lumen of the vessel, narrowing the lumen and obstructing blood flow; also called plaque |
| atherosclerosis: | abnormal accumulation of lipid deposits and fibrous tissue within arterial walls and the lumen contractility: |
| coronary artery bypass graft (CABG): | a surgical procedure in which a blood vessel from another part of the body is grafted onto the occluded coronary artery below the occlusion in such a way that blood flow bypasses the blockage |
| creatine kinase (CK): | an enzyme found in human tissues; one of the three types of CK is specific to heart muscle and may be used as an indicator of heart muscle injury |
| high-density lipoprotein (HDL): | a protein-bound lipid that transports cholesterol to the liver for excretion in the bile; composed of a higher proportion of protein to lipid than low-density lipoprotein; exerts a beneficial effect on the arterial wall ischemia: |
| low-density lipoprotein (LDL): | a protein-bound lipid that transports cholesterol to tissues in the body; composed of a lower proportion of protein to lipid than high-density lipoprotein; exerts a harmful effect on the arterial wall |
| metabolic syndrome: | a cluster of metabolic abnormalities including insulin resistance, obesity, dyslipidemia, and hypertension that increase the risk of cardiovascular disease |
| myocardial infarction (MI): | death of heart tissue caused by lack of oxygenated blood flow |
| percutaneous coronary intervention (PCI): | an invasive procedure in which a catheter is placed in a coronary artery, and one of several methods is employed to remove or reduce a blockage within the artery |
| percutaneous transluminal coronary angioplasty (PTCA): | a type of percutaneous coronary intervention in which a balloon is inflated within a coronary artery to break an atheroma and open the vessel lumen, improving coronary artery blood flow |
| stent: | a woven mesh that provides structural support to a coronary vessel, preventing its closure |
| sudden cardiac death: | abrupt cessation of effective heart activity |
| thrombolytic: | an agent or process that breaks down blood clots |
| troponin: | myocardial protein; measurement |
