Study Notes
Dyslipidemia Overview
- Dyslipidemia refers to abnormal lipid levels in the blood, affecting heart health.
- Key components of lipid profile include LDL-C (bad cholesterol) and HDL-C (good cholesterol).
Cholesterol Types
- LDL-C is classified as "bad" cholesterol due to its association with atherosclerosis.
- HDL-C is known as "good" cholesterol as it helps to remove LDL-C from the bloodstream.
Health Implications
- Main concern linked to dyslipidemia is the increased risk of atherosclerosis, which can lead to cardiovascular disease.
- Asymptomatic presentation is common, but it can lead to severe issues, such as myocardial infarction.
Causes and Management
- Major causes of dyslipidemia include high dietary fat intake, particularly saturated and trans fats.
- Statins are the most commonly prescribed drugs for managing dyslipidemia, reducing LDL-C and total cholesterol levels.
Statins and Their Effects
- Statins inhibit HMG-CoA reductase, an enzyme critical for cholesterol production.
- Common side effect of statins is myopathy, requiring monitoring of creatine kinase and liver function tests.
Combination Therapies
- Ezetimibe is commonly used in combination with statins to enhance lipid-lowering effects.
- Fibrates primarily target lowering triglycerides, and caution is advised when combining them with statins due to increased myopathy risk.
Dietary Recommendations
- Recommended dietary changes for managing dyslipidemia include reducing trans fats and increasing fiber intake.
Key Risks and Consequences
- Untreated dyslipidemia can lead to atherosclerosis and severe cardiovascular events.
- Elevated triglycerides significantly increase the risk of pancreatitis.
Treatment for Specific Conditions
- For familial hypercholesterolemia, when statins are not effective, PCSK9 inhibitors are recommended to manage cholesterol levels.
Risk Factors
- High intake of saturated and trans fats is a major risk factor for developing dyslipidemia, while high dietary fiber intake and physical activity are protective factors.
Dyslipidemia Risk Factors and Associations
- High intake of saturated fats is a primary risk factor for dyslipidemia.
- Hypothyroidism is commonly associated with dyslipidemia.
- Low HDL-C is frequently seen in metabolic syndrome.
- Sedentary lifestyle increases the risk of developing dyslipidemia.
Medication and Mechanisms
- Fibrates work by increasing the breakdown of triglycerides in the liver.
- Myopathy is a common side effect of fibrates.
- Ezetimibe inhibits cholesterol absorption in the intestines.
- Niacin (nicotinic acid) can cause flushing as a potential adverse effect.
Advanced Therapeutic Options
- PCSK9 inhibitors are recommended for patients with elevated LDL-C who do not respond to statins alone, functioning by increasing LDL receptor recycling.
- Dietary causes of elevated triglycerides include high carbohydrate intake.
Monitoring and Side Effects
- Liver function tests (LFTs) are essential for monitoring patients on fibrates.
- Fibrates reduce triglycerides while also increasing HDL-C levels.
- Flushing and pruritus are common side effects associated with niacin therapy.
- Omega-3 fatty acid supplements may lead to a fishy aftertaste.
Dietary Impact on Lipid Levels
- Reducing saturated fat intake is the most effective dietary change for lowering LDL-C levels.
- Patients with type 2 diabetes typically exhibit low HDL-C and high triglycerides.
Contraindications and Risk Factors
- Active liver disease is a contraindication for statin use.
- Factors such as advanced age can increase the risk of statin-induced myopathy.
- Combining fibrates with statins raises the risk of myopathy and rhabdomyolysis.
