Baroreceptors
The force of blood exerted against the vessel walls.
Blood Pressure (BP)
Swishing sound that may occur from turbulent blood flow in narrowed or atherosclerotic arteries; heard via auscultation or Doppler.
Bruit
The most definitive but most invasive test in the diagnosis of heart disease, involves passing a small catheter into the heart and injecting contrast medium.
cardiac catheterization
A calculation of cardiac output requirements to account for differences in body size; determined by dividing the cardiac output by the body surface area.
Cardiac index
The volume of blood ejected by the heart each minute.
Cardiac output (CO)
Serum lipid that includes high-density lipoproteins & low-density lipoproteins.
Cholesterol
The phase of the cardiac cycle that consists of relaxation & filling of the atria & ventricles, normally about 2/3 of the cardiac cycle.
Diastole
The amount of pressure or force against the arterial walls during the relaxation phase of the cardiac cycle.
Diastolic blood pressure
The use of ultrasound waves to assess cardiac structure & mobility, particularly of the valves.
Echocardiography
An invasive procedure during which programmed electrical stimulation of the heart is used to cause & evaluate dysthymias & conduction abnormalities to permit accurate diagnosis & treatment.
Electrophysiologic study (EPS)
A test that assesses cardiovascular response to an increased workload
exercise electrocardiography (stress test)
Term referring to the number of times the ventricles contract each minute.
Heart rate (HR)
Part of the total cholesterol value that should be more than 45 mm/ dL (>0.75 mmol/ L) for men & more than 55 mm/ dL (>0.91 mmol/ L) for women
High-density lipoprotein (HDL)
High-Density Lipoproteins (HDL)
good cholesterol
A serum marker of inflammation & a common & critical component of the development of atherosclerosis.
High-sensitivity C-reactive protein (hs-CRP)
A amino acid that is produced when proteins break down; elevated values may be a risk factor for the development of cardiovascular disease.
Homocysteine
Part of the total cholesterol value that should be less than 130 mg/ dL
low-density lipoprotein (LDL)
Low-Density Lipoproteins
Bad cholesterol
The arterial blood pressure necessary (between 60 & 70 mm Hg) to maintain perfusion of major body organs, such as the kidneys & the brain.
Mean aerial pressure (MAP)
Abnormal heart sound that reflects turbulent blood flow through normal or abnormal valves.
Murmur
The use of radionuclide techniques in cardiovascular assessment.
myocardial nuclear perfusion imaging (MNPI)
A decrease in blood pressure that occurs the first few seconds to minutes after changing from a sitting or lying position to a standing position.
orthostatic hypotension
orthostatic hypotension
postural hypotension
The number of packs of cigarettes per day multiplied by the number of years the patient has smoked; used to record a patient’s smoking history.
Pack-years
A feeling of fluttering in the chest, an unpleasant awareness of the heartbeat, or an irregular heartbeat.
Palpitations
An exaggerated decrease in systolic pressure by more than 10 mm Hg during the inspiratory phase of the respiratory cycle.
Paradoxical blood pressure
Paradoxical blood pressure
Paradoxical pulse
An abnormal sound that originates from the pericardial sac & occurs with the movements of the heart during the cardiac cycle.
Pericardial friction rub
Paradoxical blood pressure
Pulses paradoxus
The degree of myocardial fiber stretch at the end of diastole & just before contraction.
Preload
The difference between the systolic & diastolic pressures.
Pulse pressure
The amount of blood ejected by the left ventricle during each contraction.
Stroke volume (SV)
The phase of the cardiac cycle that consists of the contraction & emptying of the atria & ventricles.
Systole
The amount of pressure or force generated by the left ventricle to distribute blood into the aorta with each contraction of the heart.
Systolic blood pressure
A form of echocardiography performed through the esophagus that examines cardiac structure & function.
transesophageal echocardiography (TEE)
Serum lipid profile that includes the measurement of cholesterol & lipoproteins.
Triglycerides
A myocardial muscle protein released into the bloodstream with injury go through myocardial muscle.
Troponin
The sudden blockage of an artery, typically in the lower extremity, in the patient with chronic peripheral arterial disease.
acute arterial occlusion
a permanent localized dilation of an artery that enlarges the artery to at least 2x its normal diameter.
aneurysm
a surgical procedure performed to excise an aneurysm.
aneurysmectomy
Measurement of arterial insufficiency based on the ratio of ankle systolic pressure to brachial systolic pressure.
Ankle-Brachial Index (ABI)
The surgical procedure most commonly used to increase arterial blood flow in the affected limb of a patient with peripheral arterial disease.
arterial revascularization
Painful ulcers caused by diminished blood flow through an artery that develop on the toes (often the great toe), between the toes, or on the upper aspect of the foot.
arterial ulcers
the thickening and hardening of the arterial wall, often associated with aging.
arteriosclerosis
A surgical opening into an artery
arteriotomy
An invasive nonsurgical technique in which a high-speed, rotating metal burr uses fine abrasive bits to scrape plaque from inside an artery while minimizing damage to the vessel surface.
atherectomy
a type of arteriosclerosis that involves the formation of plaque within the arterial wall; the leading contributor to coronary artery & cerebrovascular disease.
Atherosclerosis
Belonging to the person; for example, when a person’s vein is moved from one part of the body to another.
autogenous
A complex, multi-step process by which blood forms a protein-based structure (clot) in an appropriate area of tissue injury to prevent excessive bleeding while maintaining whole-body blood flow (perfusion).
