    Study Notes

    Hypertension

    • Pathophysiology: Increased sodium intake, RAAS system dysfunction, aldosterone, and sympathetic nervous system activation.
    • Pharmacology: Diuretics (loop, thiazide, potassium-sparing), calcium channel blockers, alpha/beta-blockers, vasodilators, and ACE inhibitors.

    Coronary Artery Disease (CAD)

    • Pathophysiology: Atherosclerosis in coronary arteries due to LDL cholesterol buildup, reducing blood flow.
    • Pharmacology: Antiplatelets, anticoagulants, calcium channel blockers, statins, and nitrates.

    Congestive Heart Failure (CHF)

    • Pathophysiology: Progressive disease where decreased cardiac output fails to meet bodily needs, involving both left and right-sided heart failure, with symptoms like edema, hepatomegaly, and JVD.
    • Pharmacology: ACE inhibitors, ARBs, vasodilators, diuretics, beta-blockers, and cardiac glycosides like digoxin.

    Peripheral Arterial Disease (PAD) and Chronic Venous Insufficiency (CVI)

    • PAD Pathophysiology: Chronic obstruction of peripheral arteries leading to partial/total arterial occlusion.
    • Pharmacology: Antihypertensives, statins, and antiplatelets.

    Chronic Venous Insufficiency (CVI)

    • Pathophysiology: Long-term venous insufficiency due to faulty valves.
    • Pharmacology: Steroids, antibiotics, anticoagulants.

    Anticoagulants and Antiplatelets

    • Anticoagulants: Heparin and warfarin; prevent clot formation, particularly in post-op patients or those at risk of DVT.
    • Antiplatelets: Aspirin and clopidogrel; prevent platelet aggregation, reducing clot risk.

    Anemia

    • Pathophysiology: Deficiency in necessary components for normal RBC function leading to reduced oxygen transport.
    • Pharmacology: Iron supplements, vitamin B12, and other medications to manage anemia, focusing on iron deficiency or pernicious anemia.

    Diuretics

    • Loop Diuretics (e.g., Furosemide, Torsemide): Block sodium and water reabsorption in the loop of Henle.
    • Therapeutic Use: Rapid fluid removal, hypertension, and heart failure.
    • Complications: Dehydration, hypotension, ototoxicity, hypokalemia, and nocturia.
    • Interactions: Digoxin, NSAIDs – additive hypotension.

    Thiazide Diuretics

    • Drugs: Hydrochlorothiazide
    • Mechanism of Action (MOA): Block sodium and water reabsorption in the distal convoluted tubule.
    • Therapeutic Use: First-line treatment for essential hypertension and heart failure.
    • Complications: Dehydration, hypokalemia, hyperglycemia, nocturia.
    • Contraindications: Renal impairment.

    Potassium-Sparing Diuretics

    • Drugs: Spironolactone
    • MOA: Block aldosterone, increasing sodium and water excretion while retaining potassium.

    • Contraindications: Hyperkalemia, kidney/liver disease.
    • Interactions: ACE inhibitors and ARBs.

    Calcium Channel Blockers

    • Drugs: Nifedipine, Amlodipine
    • MOA: Block calcium channels in blood vessels, leading to vasodilation of vascular smooth muscle.

    • Complications: Reflex tachycardia, orthostatic hypotension, and peripheral edema.

    Beta Blockers

    • Drugs: Metoprolol, Atenolol, Propranolol, Carvedilol, Labetalol
    • MOA: Block beta receptors in the heart, reducing heart rate and contractility; block renin release in the kidneys.
    • Therapeutic Use: Hypertension, heart failure, and arrhythmias.
    • Complications: Bradycardia, decreased cardiac output, orthostatic hypotension, bronchoconstriction (Beta-2), and inhibited glycogenolysis (Beta-2).

    Alpha Adrenergic Blockers

    • Drugs: Prazosin (peripheral), Clonidine (central)
    • MOA: Block alpha-1 receptors on arterioles for vasodilation; central drugs reduce sympathetic outflow.
    • Therapeutic Use: Hypertension.
    • Complications: First-dose orthostatic hypotension (peripheral), rebound hypertension (central).

    • MOA: Positive inotropic effect (increased contraction force), negative chronotropic effect (decreased heart rate).
    • Therapeutic Use: Heart failure and dysrhythmias.
    • Complications: Dysrhythmias (especially with hypokalemia), cardiotoxicity, gastrointestinal effects (anorexia, nausea), and central nervous system effects (vision changes, halos).

    Statins

    • Drugs: Atorvastatin, Simvastatin
    • MOA: Inhibit HMG-CoA reductase, reducing cholesterol production in the liver.
    • Therapeutic Use: Prevention of cardiac events, stroke, and clot formation.

    Nitrates

    • Drugs: Isosorbide Mononitrate
    • MOA: Dilates veins, reducing venous return (preload), decreasing oxygen demand.
    • Therapeutic Use: Prophylaxis of stable angina.
    • Complications: Headache, orthostatic hypotension, reflex tachycardia.

    Anticoagulants

    • Examples: Warfarin, Heparin, Enoxaparin
    • MOA: Warfarin inhibits vitamin K-dependent clotting factors; heparin/enoxaparin inhibits thrombin and factor Xa.
    • Use: Prevent/treat DVT, PE, stroke in atrial fibrillation.
    • Side Effects: Bleeding and thrombocytopenia.
    • Contraindications: Active bleeding and pregnancy (for warfarin).
    • Monitoring: INR (warfarin), aPTT (heparin).
    • Antidote: Vitamin K (warfarin), protamine sulfate (heparin).

    Antiplatelets

    • Examples: Aspirin, Clopidogrel
    • MOA: Aspirin inhibits thromboxane A2, reducing platelet aggregation; clopidogrel blocks ADP receptors on platelets.

    • Use: Treat B12 deficiency and pernicious anemia.
    • Side Effects: Rare, potential injection site reactions.

    Monitoring Parameters

    • Loop Diuretics: Electrolytes (especially K+ and Na+), blood pressure, fluid balance, renal function.
    • Potassium-Sparing Diuretics: Serum potassium, renal function.
    • Beta-blockers: Heart rate, blood pressure.
    • ACE Inhibitors: Serum potassium, serum creatinine.
    • ARBs: Serum potassium, blood pressure.
    • Calcium Channel Blockers: Blood pressure, heart rate.
