Study Notes
Hypertension Overview
- Hypertension affects 30-40% of adults aged 20 or older in the US, representing 80 million people.
- Despite progress in prevention and treatment, 50% of cases remain inadequately managed.
- Blood pressure control is complex, involving vascular, cardiac, and renal physiology.
Factors Influencing Blood Pressure
- Mean arterial pressure (MAP) is determined by cardiac output multiplied by peripheral resistance.
- Increased cardiac output results from factors like increased heart rate, contractility, and sodium/water retention.
- Increased peripheral resistance stems from vasoconstriction.
- Antihypertensive therapy aims to reduce one or more of these factors to lower blood pressure.
Target Organ Damage
- Hypertension negatively impacts numerous organs.
- Clinically, assessing for target organ damage helps determine the severity and management approach.
- Target organ damage is sometimes referred to as end-organ damage.
Hypertension-Related Organ System Effects
- Cardiac: Coronary artery disease, left ventricular hypertrophy, cardiac failure.
- Cerebrovascular: Transient ischemic attacks, stroke.
- Peripheral Vascular: Absence of one or more major pulses; intermittent claudication.
- Renal: Serum creatinine greater than 1.5 mg/dL; proteinuria; 3rd leading cause of dialysis.
- Retinopathy: Hemorrhages or exudates, with or without papilledema.
Thiazide Diuretics
- Mechanism: Inhibit sodium and chloride reabsorption in the early distal tubule and thick ascending loop of Henle.
- Effects: Decreased plasma volume; lower stroke volume; lower cardiac output.
- Adverse effects: Hypokalemia (approximately 15% of patients, especially with high doses), hypomagnesemia, hypercalcemia, hyperglycemia, hyperuricemia, hyperlipidemia.
ACE Inhibitors
- Mechanism: Block the enzyme converting angiotensin I to angiotensin II (renin-angiotensin-aldosterone system), reducing vascular resistance, decreasing sodium and water retention.
- Adverse Effects: Cough (3-15% of patients), hypotension, rash, angioedema, hyperkalemia.
Angiotensin II Receptor Blockers (ARBs)
- Mechanism: Inhibit angiotensin II receptors, reducing blood pressure by decreasing vascular resistance and aldosterone secretion.
- Adverse Effects: Lower incidence of cough than ACE inhibitors; hyperkalemia, fatigue, headache, dizziness.
Calcium Channel Antagonists
- Mechanism: Block L-type calcium channels, reducing calcium entry into vascular and cardiac cells.
- Types: Dihydropyridines (e.g., amlodipine, nifedipine), diphenylalkylamines (e.g., verapamil), benzothiazepines (e.g., diltiazem).
- Adverse Effects: Vary by class; potential for constipation, bradycardia, worsening heart failure.
Beta Blockers
- Mechanism: Block beta-adrenergic receptors in the heart and kidneys. Negative inotropic and chronotropic effects; reduce cardiac output and renin release.
- Adverse Effects: Bronchoconstriction, peripheral vasoconstriction, interference with glycogenolysis, exacerbation of heart failure, fatigue, depression, sleep disturbance.
Alpha-1 Receptor Blockers
- Mechanism: Block alpha-1 adrenergic receptors, decreasing total peripheral resistance.
- Adverse effects: First dose syncope, orthostatic hypotension, dizziness, drowsiness, headaches.
Alpha-2 Agonists
- Mechanism: Stimulate alpha-2 receptors in the brainstem, decreasing sympathetic outflow to the heart, kidneys, and peripheral vasculature.
- Adverse Effects: Sedation, drowsiness, dry mouth, rebound hypertension, impotence, decrease libido.
Clinical Use Considerations
- Thiazide diuretics are a typical first-line choice in most hypertension cases.
- Specific agents choices depend on specific patient factors such as associated diseases (e.g., diabetes, post-myocardial infarction), high risk of coronary artery disease, recurrent cerebrovascular accident, kidney disease).
- Some drugs are considered for specific indications (e.g., benign prostatic hyperplasia).
