Section 3: Hyperlipidemia
Question | Answer |
---|---|
What is hyperlipidemia? | A condition that affects the cardiovascular system that is characterized by excessive amounts of fat or cholesterol in the blood. |
What are risk factors for hyperlipidemia? | Advancing age Family history of heart attack smoking hypertension low levels of high-density lipoprotein (HDL): less than 40 mg/dL |
What are the signs of hyperlipidemia? | high levels of low-density lipoprotein (LDL): greater than 130 mg/dL High levels of total cholesterol: greater than 200 mg/dL High triglycerides: greater than 150 mg/dL Low levels of high-density lipoprotein (HDL): less than 40 mg/dL |
What are the symptoms of hyperlipidemia? | None, unless complications such as a heart attack are present |
What is the basis of the Framingham Risk Score used to evaluate the status of hyperlipidemia? | It is based on the 10-year risk of developing a heart attack. |
What are complications of unmanaged hyperlipidemia? | Stroke or cerebrovascular accident (CVA) Heart attack or myocardial infarction Angina (chest pain) |
Nonpharmacological therapy for hyperlipidemia | Reducing saturated fat intake Restricting cholesterol: less than 200 mg/day Increasing fiber intake Managing weight Increasing physical activity Quitting smoking |
Mechanism of action, possible side effects, an examples of HMG-CoA reductase inhibitors | Mechanism of action: Inhibits the enzyme responsible for making the precursor for cholesterol synthesis Possible side effects: Rhabdomyolysis, myalgia, liver damage Examples: Atorvastatin, lovastatin, pravastatin |
Mechanism of action, possible side effects, and examples of bile acid sequestrants | Possible side effects: When used in conjunction with HMG-CoA; back or joint pain or both, diarrhea, abdominal pain, pancreatitis Ex: Cholestyramine, colesevelam, colestipol |
Mechanism of action, possible side effects, and example of a fibrate | Mechanism of action: Inhibits lipoprotein lipoprotein lipase to decrease triglycerides Possible side effects: Gallstones, constipation, myalgia, liver damage, gastrointestinal upset Ex: Fenofirate |
