Pharmacology 252 - Antianginal Drugs Flashcards
Acute coronary syndrome
A spectrum of clinical presentations compatible with acute myocardial ischemia, ranging from those for ST-segment elevation myocardial infarction (STEMI) to presentations found in non–ST-segment elevation myocardial infarction (NSTEMI) or in unstable angina.
Angina pectoris
Chest pain that occurs when the heart’s supply of blood carrying oxygen is insufficient to meet the demands of the heart.
atherosclerosis
A common form of arteriosclerosis involving deposits of fatty, cholesterol-containing material (plaques) within arterial walls.
chronic stable angina
Chest pain that is primarily caused by atherosclerosis, which results in long-term but relatively stable levels of obstruction in one or more coronary arteries.
Coronary arteries
Arteries that deliver oxygen-carrying blood to the heart muscle.
Coronary artery disease
Any one of the abnormal conditions that can affect the arteries of the heart and produce pathological effects, especially a reduced supply of oxygen and nutrients to the myocardium
Ischemia
Poor blood supply to an organ.
Ischemic heart disease
Poor blood supply to the heart via the coronary arteries.
Myocardial infarction
Necrosis of the myocardium following interruption of blood supply; almost always caused by atherosclerosis of the coronary arteries. Commonly called a heart attack.
Reflex tachycardia
A rapid heartbeat caused by a variety of autonomic nervous system effects, such as blood pressure changes, fever, or emotional stress.
Unstable angina
Clinical presentation of acute coronary syndrome with cardiac ischemia, without persistent ST-segment elevation on electrocardiogram and with no detectable release of the enzymes and biomarkers of myocardial necrosis.
Vasospastic angina
Ischemia-induced myocardial chest pain caused by spasms of the coronary arteries; also referred to as Prinzmetal’s or variant angina.
