Management of Patients With Coronary Vascular Disorders-Chapter 28

QuestionAnswer
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
