ACE inhibitor
blocks the action of enzyme that causes blood vessels to contract. Used to treat hypertension.
anemia
lower than normal levels of RBCs causing fatigue and SOB Severity is determined based on hemoglobin levels. Less oxygen means less energy.
aneurysm
localized weak spot or balloon like enlargement of the wall of an artery.
angina
condition that occurs due to inadequate blood flow (ischemia) to myocardium resulting in severe chest pain. May progress into MI.
angioplasty
technique of mechanically widening a narrowed or obstructed blood vessel.
anticoagulant
slows coagulation and prevents new clots from forming.
aplastic anemia
characterized by an absence of all formed blood elements caused by the failure of blood cell production in the bone marrow.
arrhythemia
loss of normal heart rhythm. Usually due to abnormality with electrical conduction.
atherectomy
surgical removal or plaque buildup from the interior of an artery.
atheroma
deposit of plaque, typically with atherosclerosis
atherosclerosis
hardening and narrowing of arteries caused by buildup of cholesterol on interior walls
atrial fibrillation
most common type of tachycardia. Atrial contractions are twitchy causing quivering of the atria.
automated external defibrillator
samples electrical rhythms and delivers shock is necessary. designed for use by nonprofessionals when defibrillation is required.
beta-blocker
reduces workload of the heart by slowing the heart rate. Prescribed to lower BP, relieve angina or treat heart failure.
blood dyscrasia
Pathologic condition of the cellular elements of the blood.
