What is variant angina?
chest pain that is caused by acute spasm of the coronary arteries rather than by physical or emotional exertion
What does "PTCA" represent?
percutaneous transluminal coronary angioplasty
What is mitral stenosis?
inability of the mitral valve to fully open
What is myocardial infarction?
clot within the coronary arteries
What is coronary artery disease?
atherosclerosis of the coronary arteries
What is myocardial ischemia?
reduced blood supply to cardiac muscle cells
The primary means by which anti-anginal drugs reduce frequency or terminate acute anginal pain is to reduce the myocardial demand for oxygen. Name four mechanisms to accomplish this.
slowing the heart rate
causing heart to receive less blood by dilating veins
causing the heart to contract with less force
lowering blood pressure therefore less resistance in the chambers
What is the action of organic nitrates in relieving angina?
dilating veins and the coronary artieries
What is the most commonly known organic nitrate used to treat angina?
nitroglycerin
What is the action of beta-adrenergic blockers in relieving angina?
decreasing the oxygen demands on the heart (slowing heart rate and reducing contractility)
Beta blockers can be cardioselective and non-selective (True or False)
True
What is the action of calcium channel blockers in relieving angina?
dilating the coronary veslles and reducing the workload on the heart (lowering blood pressure and slowing heart rate)
Thrombolytics
dissolve clots blocking the coronary arteries
Beta-adrenergic blockers are used in MI to:
slow the heart rate
decrease contractility
reduce blood pressure
"CVA" represents
cardiovascular accident (stroke)
In physiological terms, what is a CVA?
thrombus in a vessel serving the brain
What is a brain attack?
Another name for a stroke.
