20

vas/o

vessel

21

vascul/o

vessel

22

ven/o, ven/i

vein

23

ventricul/o

ventricle, lower heart chamber

24

acute coronary syndromes (ACSs)

unstable angina and myocardial infarcation (heart attack) which are consequences of plaque rupture in coronary arteries

25

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

26

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

27

auscultation

listening for sounds in blood vessels or other body structures, typically using a stethoscope

28

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

29

biventricular pacemaker

device enabling ventricles to beat together (in synchrony) so that more blood is pumped out of the heart

30

bruit

abnormal blowing or swishing sound heard during auscultation of an artery or organ

31

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

32

cardiac arrest

sudden, unexpected stoppage of heart action, often leading to sudden cardiac death

33

cardiac tamponade

pressure on the heart caused by fluid in the pericardial space

34

claudication

pain, tension, and weakness in a leg after walking has begun, but absence of pain at rest

35

digoxin

drug that treats arrhythmias and strengthens the heartbeat

36

embolus
(plural: emboli)

clot of other substance that travels to a distant location and suddenly blocks a blood vessel

37

infarction

area of dead tissue

38

nitrates

drugs used in the treatment of angina, they dilate blood vessels, increasing blood flow and oxygen to myocardial tissue

39

nitroglycerin

nitrate drug used in the treatment of angina.

40

occlusion

closure of a blood vessel due to blockage

41

palpitations

uncomfortable sensations in the chest related to cardiac arrhythmias, such as premature ventricular contractions (PVSc)

42

patent

open

43

pericardial friction rub

scraping or grating noise heard on auscultation of the heart; suggestive of pericarditis

44

petechiae

small, pinpoint hemorrhages

45

statins

drugs used to lower cholesterol in the bloodstream

46

thrill

vibration felt over an area of turmoil in blood flow (as a blocked artery)

47

vegetations

clumps of platelets, clotting proteins, microorganisms, and red blood cells on diseased heart valves
