Q

Hyperlipidemia

Study These Flashcards
A

Abnormally high blood levels of lipids, which are non-water-soluble molecules, such as fat and cholesterol

21
Q

Plaque

Study These Flashcards
A

Buildup of deposits in the arteries

22
Q

Ischemia

Study These Flashcards
A

Reduced oxygen supply to a body part of organ

23
Q

Peripheral Artery Disease (PAD)

Study These Flashcards
A

Atherosclerosis occurring in the lower extremities, such as the feet, calves, legs, or in the arms

24
Q

Ankle-Breaking Index (ABI)

Study These Flashcards
A

Test in which a measure of blood pressure in your feet is compared to blood pressure in your arm to determine blood flow

25
Coronary Heart Disease (CHD)
A narrowing of the small blood vessels that supply blood
26
Myocardial Infarction (MI; Heart Attack)
A blockage of normal blood supply to an area in the heart
27
Coronary Thrombosis
A clot or an atherosclerosis narrowing that blocks a coronary artery
28
Thrombus
A clot or blockage in the blood vessels
29
Embolus
When a clot becomes dislodges and moves through the circulatory system
30
Arrhythmia
An irregularity in heartbeat
31
Fibrillation
A sporadic, quivering pattern of heartbeat that results in extreme inefficiency in moving blood through the cardiovascular system
32
Angina Pectoris
Chest pain occurring as a result of reduced oxygen flow to the heart
33
Congestive Heart Failure (CHF)
An abnormal cardiovascular condition that reflects impaired cardiac pumping and blood flow; pooling blood leads to congestion in body tissues
34
Cardiomyopathy
Damage to heart muscle
35
Congenital Cardiovascular Defect
Cardiovascular problem that is present at birth
36
Rheumatic Heart Disease
A heart disease caused by untreated streptococcal infection of the throat
37
Stroke
A condition occurring when the brain is damaged by disrupted blood supply; also called cerebrovascular accident
38
Aneurysm
A weakened blood vessel that may bulge under pressure and, sever cases, burst
39
Transient Ischemic Attacks (TIAs)
Brief interruption of the blood supply to the brain that causes to the brain that causes only temporary impairment; often an indicator of impending major stroke
40
Cardiometabolic Risks
Risk factors that impact both the cardiovascular system and the body's biochemical metabolic processes
41
Metabolic Syndrome (MetS)
A group of metabolic conditions occurring together that increases a person's risk of heart disease, stroke, and diabetes
42
Plant Sterols
Essential components of plant membranes that, when consumed in the diet, appear to help lower cholesterol levels
43
C-Reactive Protein (CRP)
A protein whose blood levels rise in response to inflammation
44
Homocysteine
An amino acid normally present in the blood that, when found at high levels, may be related to higher risk of cardiovascular disease
45
Electrocardiogram (ECG)
A record of the electrical activity of the heart; may be measured during a stress test
46
Angiography
A technique for examining blockages in heart arteries
47
Coronary Bypass Surgery
A surgical technique whereby a blood vessel taken from another part of the body is implanted to bypass a clogged coronary artery
48
Angioplasty
A technique in which a catheter with a balloon at the tip is inserted into a clogged artery; the balloon is inflated to flatten fatty deposits against artery walls and a stent is typically inserted to keep the artery open
49
Thrombolysis
Injection of an agent to dissolve clots and restore some blood flow, thereby reducing the amount of tissue that dies from ischemia
