Angiotensin | Potent vasoconstrictor |
Angiotensin-coverting enzyme | Enzyme that catalyzes the conversion angiotensin I to angiotensin II |
Atheromas | Hard plaque formed with an artery |
Automaticity | Spotaneous depolarization of heart cells |
Body mass index | Measure of human body size and proportion |
Cardiac output | Volume of blood ejected from the left ventricle in one minute |
Cardioglycosides | Class of drugs derived from the foxglove plant |
Diastolic blood pressure | Measure of blood pressure when the heart is at rest |
Digitalization | Method of dosage with cardioglycosides that rapidly produces effective drug levels |
Ejection fraction | Percentage of blood ejected from the left ventricle with each heart beat |
Gynecomastia | Painful breast enlargement in men |
Heart failure | Clinical syndrome in which the heart is unable to pump blood at a rate to meet the body's metabolic needs |

Hyperkalemia | Excessive serum potassium levels |
Hypernatremia | Excessive serum sodium levels |
Hyperuricemia | Increased uric acid levels in the blood produced by some diuretics |
Hypokalemia | Deficient serum potassium levels |
Hyponatremia | Deficient serum sodium levels |
Ischemia | Deficient blood supply to an area of the body |
Ishemic heart disease | Condition is which heart muscle is damaged because of an absence of blood supply |
Metabolic syndrome | Risk factor of hypertension that promotes the development of atherosclerosis and cardiovascular disease |
Natriuretic peptides | Hormones that play a role in cardiac homeostasis |
Necrosis | Cell death that may be caused by lack of blood and oxygen |
Nocturia | Nighttime urination |
Orthostatic hypotension | Sudden drop in blood pressure that occurs hwen arising from lying down or sittin to standing |
Peripheral vascular resistance | Resistance to the flow of blood in peripheral arterial vessels |

Renin-Aldosterone-angiotensin system | Syatem that is activated when there is a drop in renal blood flow that increases blood volume, blood flow to the kidney, vasoconstriction, and blood pressure |
Stroke volume | Equal to the volume of blood ejected by the left ventricle during each cardiac contraction minus the volume of blood in the ventricle at the end of systole |
Systolic blood pressure | Measure of pressure when the heart's ventricles are contracting |
Thrombus | Stationary blood clot |
Vasospasm | Spasms that constrict blood vessels and reduce the flow of blood and oxygen |
