Chp 11-Cardio Sys 3

Definitions: Davi-Ellen Chabner, The Language of Medicine, 8th Edition

QuestionAnswer
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.
