    Study Notes

    Coronary Heart Disease (CHD) Overview

    • Major risk factor for CHD includes hypertension, which increases the strain on the heart and blood vessels.
    • The primary cause of CHD is atherosclerosis, the buildup of plaque in the coronary arteries.
    • Diabetes mellitus significantly increases the risk of developing CHD, due to its impact on blood vessel health.
    • Other conditions like hyperthyroidism, asthma, and osteoporosis do not significantly contribute to CHD risk.

    Pharmacological Management of CHD

    • Beta-blockers are commonly prescribed to manage angina in CHD patients by reducing myocardial oxygen demand.
    • Statins reduce cholesterol levels by inhibiting cholesterol synthesis through HMG-CoA reductase, important for long-term CHD management.
    • Common side effect of statins is myopathy, which may affect muscle health.
    • Use of glyceryl trinitrate (GTN) spray is indicated for the acute treatment of angina due to its rapid vasodilatory effects.

    Mechanisms of Action of Various Drug Classes

    • Nitrates, used in angina management, often cause headaches as a side effect due to vasodilation.
    • ACE inhibitors inhibit the angiotensin-converting enzyme to reduce vasoconstriction, and potential side effects include hyperkalemia.
    • Calcium channel blockers help in reducing myocardial oxygen demand by decreasing heart rate.
    • Antiplatelets, like aspirin, prevent platelet aggregation, crucial in preventing blood clots in CHD patients.
    • PCSK9 inhibitors lower LDL cholesterol by preventing the breakdown of LDL receptors in the liver.

    Adverse Effects and Considerations

    • Long-term nitrate therapy can lead to tolerance and hypotension, highlighting the need for careful management.
    • Bradycardia is a notable side effect of beta-blockers, requiring monitoring in patients.
    • Gastrointestinal bleeding is a potential adverse effect associated with long-term use of antiplatelet agents, necessitating caution in prescribing.

    Causes of Myocardial Ischemia

    • Vasospasm is identified as a potential cause of coronary artery spasm leading to ischemia, alongside atherosclerosis.

    Acute Coronary Syndrome (ACS) Overview

    • The most common cause of ACS is atherosclerosis with plaque rupture.
    • Non-modifiable risk factors include family history of coronary heart disease (CHD), while smoking, high cholesterol, and hypertension are modifiable.

    Antiplatelet Therapy

    • Antiplatelet drugs like aspirin primarily work by preventing platelet aggregation.
    • A major adverse effect of long-term aspirin use is gastrointestinal bleeding.

    Cholesterol Management

    • Statins are the drug class used to lower LDL cholesterol in ACS patients, also stabilizing plaques and reducing recurrent ACS risk.
    • ACE inhibitors are beneficial in reducing blood pressure and preventing heart failure in ACS patients.

    Role of Beta-Blockers

    • Beta-blockers reduce myocardial oxygen demand by lowering heart rate and blood pressure and help in reducing the risk of arrhythmias after ACS.

    Nitrates Functionality

    • Nitrates, such as glyceryl trinitrate, dilate both veins and arteries to decrease cardiac workload; common side effect includes dizziness.

    Thrombolytic Therapy

    • Fibrinolysis (thrombolysis) is utilized to restore blood flow during ST-Elevation Myocardial Infarction (STEMI).
    • A contraindication for thrombolytic therapy is recent head trauma.

    Anticoagulants

    • Anticoagulants (e.g., heparin) are often combined with antiplatelet agents for ACS management; a major side effect includes bleeding.

    Calcium Channel Blockers

    • These drugs help manage ACS by dilating coronary arteries and reducing heart workload.

    Enzyme Markers for Diagnosis

    • The enzyme marker most commonly measured to confirm myocardial damage in ACS is troponin.
