Cardiovascular Disease/ metabolic syndrome Flashcards
Cardiovascular disease is the most common cause of death causing approximately what percentage of deaths?
Which percentage of these deaths occur in low and middle income countries?
30% of deaths are from cardiovascular disease
80% of CVD death occurred in the low and middle income countries
(due to: higher exposure to risk factors like smoking, lack of prevention programs, no access to care, early detection systems)
What are the four major groups of cardiovascular disease (which areas of the body do they affect)
Heart and blood vessels
Heart-coronary artery disease, heart disease
Brain or vessels that supply the brain-cerebrovascular disease
Vessels that supply the arms and legs-peripheral artery disease
Define Arthrosclerosis
Hardening of the arteries due to the accumulation of plaque on the arterial wall
Plaque-cholesterol lipids calcium macrophages and fibrin
List in order-the stages of Arthrosclerosis
Endothelial cell injury or dysfunction
Fatty streak
Fibrotic plaque
Complicated lesion
List risk factors for arthrosclerosis
Smoking
Diabetes
Hypertension
Increased LDL
Decreased HDL
Auto immunity diseases
Air pollution
This lipidemia
Insulin resistance
Heavy alcohol consumption
Obesity
Physical inactivity
Increased C-reactive proteins
Age
Family history
Describe the clinical manifestations of Arthrosclerosis
Most individuals are asymptomatic
Large plaques that occlude most of the vessels may result in poor perfusion of tissues
Evidence of any form of arthrosclerosis is treated like coronary artery disease
Complicated plaques-high risk of vessel occlusion-infarction of tissues-heart attack, stroke
Treatments for arthrosclerosis?
Focused on identifying clients prior to rupture
-Treating with drugs, stabilizing plaques, reducing plaque size
If no immediate danger-
-Risk factor reduction, prevent further progression
List (primary secondary) prevention of arthrosclerosis?
Primary prevention
-Lifelong: maintenance of healthy weight, Avoid smoking and secondhand smoke, exercise regularly
Secondary prevention
-Screening high-risk individuals, risk factor reduction: lifestyle modification, drugs
Peripheral artery disease affects how many Americans what are the risk factors and what are the predictors of systemic disease?
Approximately 10 million Americans are affected by peripheral artery disease
Prevalent in smokers and people with diabetes
Predictor of systemic disease:-two times greater risk of coronary artery disease than those without PAD
Peripheral artery disease can lead to what?
Can lead to chronic or acute obstruction of peripheral vessels
More common in legs
Severe pain and tissue damage in cases of complicated plaques that lead to obstruction
Occlusion of coronary artery’s does what
Deprives the heart muscle of oxygen
Ischemia
Infarction
Define ischemia and infarction
Ischemia-
Reduction in blood flow of 50%, sufficient to impair cells metabolism in high-demand situations
Cells remain alive, but do not function properly
begins within 10 seconds of vessel occlusion
Infarction-
Persistent ischemia leading to death of muscle cells
Cells die after about 20 minutes
Often caused by complicated plaques
Give particular’s of coronary artery disease-how much of the US population over the age of 20 has it risk factors statistics
CAD-coronary artery disease
Estimate: 7% of US population over the age of 20
One heart attack every 25 seconds
One in every six deaths
Risk factors are the same for those with arthrosclerosis
Give statistics for metabolic syndrome (a.k.a. syndrome X)
Constellation of conditions
Estimates approximately 25% of the global population
Especially high risk for developing coronary artery disease
3 to 4 fold increase in risk of MI
To fold increase risk of dying of MI
What are the qualifications for diagnosing metabolic syndrome
Three of the following conditions:
Obesity-abdominal obesity
High blood triglycerides
Low HDL
Insulin resistance
Hypertension
Tend to occur simultaneously presence of multiple factors increase risk more then individual factors would be expected to
