Question | Answer |
---|---|
acute coronary syndromes | Consequences of plaque rupture in coronary arteries: unstable angina and myocardial infarction. |
angina (pectoris) | Chest pain resulting from myocardial ischemia. Stable angina occurs predictably with exertion; unstable angina is chest pain that occurs more often and with less exertion. |
angiotensin-converting enzyme (ACE) inhibitor | Antihypertensive drug that blocks the conversion of angiotensin I to angiotensin II and thus dilates blood vessels. It prevents heart attacks, CHF, stroke, and death. |
auscultation | Listening for sounds in blood vessels or other body structure, typically using a stethoscope. |
beta-blockers | Drugs used to treat angina, hypertension, and arrhythmias. They block the action of epinephrine (adrenaline) at receptor sites on cells, slowing the heartbeat and reducing the workload on the heart. |
biventricular pacemaker | Device enabling ventricles to beat together (in synchrony) so that more blood is pumped out of the heart. |
bruit | An abnormal blowing or swishing sound heart during auscultation of an artery or organ. |
calcium channel blockers | Drugs used to treat angina and hypertension. They dilate blood vessels by blocking the influx of calcium into muscle cells lining vessels. |
cardiac arrest | Sudden, unexpected stopping of heart action; sudden cardiac death. |
cardiac tamponade | Pressure on the heart caused by fluid in the pericardial space. |
claudication | Pain, tension, and weakness in a leg after walking has begun, but absence of pain at rest. |
digoxin | A drug that treats arrhythmias and strengthens the heartbeat. |
embolus (pl emboli) | A clot or other substance that travels to a distant location and suddenly blocks a blood vessel. |
infarction | Area of dead tissue. |
nitrates | Drugs used in the treatment of angina. They dilate blood vessels, increasing blood flow and oxygel to myocardial tissue. |
nitroglycerin | A nitrtae drug used in the treatment of angina. |
Occlusion | Closure of a blood vessel |
palpitations | Uncomfortable sensations in the chest related to cardiac arrhythmias, such as premature ventricular contractions (PVCs). |
patent | Open. |
pericardial friction rub | Scrabing or grating noise heard on auscultation of the heart; suggestive of pericarditis. |
petechiae | Small, pinpoing hemorrhages. |
statins | Drugs used to lower cholesterol in the bloodstream. |
thrill | Vibration felt on touching the body over an area of turmoil in blood flow (as a blocked artery). |
vegetations | Clumps of platelets, clotting proteins, microorganisms, and red blood cells on the endocardium in conditions such as bacterial endocarditis and rheumatic heart disease. |
