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.

- Complications: Dehydration, hypokalemia, hyperglycemia, nocturia.
- Contraindications: Renal impairment.
Potassium-Sparing Diuretics

- Complications: Hyperkalemia.
- Contraindications: Hyperkalemia, kidney/liver disease.
- Interactions: ACE inhibitors and ARBs.
Calcium Channel Blockers
- Drugs: Nifedipine, Amlodipine

- Complications: First-dose hypotension, dry cough, hyperkalemia, neutropenia, and angioedema.
ARBs
- Drugs: Losartan
- MOA: Block angiotensin II receptors, leading to vasodilation and excretion of sodium and water.

- 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: Prevention of MI, stroke, and stent thrombosis.
Vitamin B12
- MOA: Essential for DNA synthesis and red blood cell production.
- 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.
- Cardiac Glycosides: Serum digoxin levels, electrolytes, heart rate.
- Statins: Liver enzymes, muscle pain/weakness.
- Nitrates: Blood pressure.
