    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.
