acute coronary syndromes (ACSs)
unstable angina and myocardial infarcation (heart attack) which are consequences of plaque rupture in coronary arteries
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, causing blood vessels to dilate. it prevents heart attacks, CHF, stroke, and death
auscultation
listening for sounds in blood vessels or other body structures, typically using a stethoscope
beta-blocker
drug used to treat angina, hypertension, and arrhythmias. it blocks 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
abnormal blowing or swishing sound heard during auscultation of an artery or organ
calcium channel blocker
drug used to treat angina and hypertension. it dilates blood vessels by blocking the influx of calcium into muscle cells lining vessels
cardiac arrest
sudden, unexpected stoppage of heart action, often leading to 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
drug that treats arrhythmias and strengthens the heartbeat
embolus
plural: emboli
clot of 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 oxygen to myocardial tissue
nitroglycerin
nitrate drug used in the treatment of angina.
occlusion
closure of a blood vessel due to blockage
palpitations
uncomfortable sensations in the chest related to cardiac arrhythmias, such as premature ventricular contractions (PVSc)
patent
open
pericardial friction rub
scraping or grating noise heard on auscultation of the heart; suggestive of pericarditis
petechiae
small, pinpoint hemorrhages
statins
drugs used to lower cholesterol in the bloodstream
thrill
vibration felt over an area of turmoil in blood flow (as a blocked artery)
vegetations
clumps of platelets, clotting proteins, microorganisms, and red blood cells on diseased heart valves
