Mini Test 2 Flashcards
Prevalence of cardiovascular disease
Declined from 50% in the 70’s to 36.3% in 2004
Factors leading to decline in cardiovascular disease
Lifestyle changes like nutrition, stopping smoking, and exercise, as well as improved medical techniques and diagnosis, improved emergency care and treatment, and improved drugs
Coronary Artery Disease
Blockage of arteries supplying cardiac tissue
Ischemia
Insufficient blood to tissue due to partial blockage of the artery
Myocardial Infarction
Severe or complete blockage, leading to cell death in the heart
Atherosclerosis
Progressive narrowing of the artery due to plaque
Arteriosclerosis
Thickening and loss of elasticity of arterial wall
Stroke
Lack of blood supply to part of the brain, causing brain tissue death
Ischemic Stroke
Blockage of vessel
Hemorrhagic Stroke
Rupture of vessels
Cerebral Hemorrhage
Cerebral artery
Subarachnoid Hemorrhage
On the surface of the brain
Predisposing factors for CAD and Stroke
Hypertension and atherosclerotic damage which can lead to weak spots
Coronary Artery Disease Risk Factors
Age, male gender, hereditary, tobacco use, blood lipid profile, hypertension, obesity/overweight, diabetes, physical inactivity, psychological stress, alcohol consumption, diet and nutrition
Heart Failure
When the ventricles cannot contract, so cardiac output is insufficient
Acute Heart Failure
Caused by heart attack resulting from toxic substances or dugs or coronary artery blockage
Chronic Heart Failure
Caused by hypertension (increases heart workload, leads to pathologic hypertrophy), multiple minor heart attacks, viral infections
Hypertension
High blood pressure at rest. This means that the heart has to work harder to pump the same amount of blood. This increases cardiac tissue’s oxygen demand and the strain on arteries and arterioles
Factors associated with hypertension
Physical inactivity, overweight/obese, hereditary, male gender, increased age, sodium sensitivity, use of tobacco products, excessive alcohol consumption, psychological stress, diabetes, oral contraceptives, and pregnancy
Controlled Factors for CAD
Smoking tobacco, blood lipid profile, hypertension, obesity/overweight, diabetes mellitus, physical inactivity, psychological stress, alcohol consumption, diet/nutrition
Uncontrolled Factors of CAD
Age, male gender, and hereditary
Total Cholesterol
<200 mg/dL
LDL-C
<130 mg/dL
HDL-C
Greater than or equal to 60 mg/dL
