Study Notes
Hypertension
- Symptoms: Often absent; severe cases may present with headache, dizziness, or visual disturbances.
- Diagnosis: Blood pressure (BP) ≥130/80 mmHg (confirmed on multiple readings); assess for end-organ damage.
- Treatment: Lifestyle changes (DASH diet, exercise, salt reduction); medications (ACE inhibitors, ARBs, CCBs, thiazide diuretics).
Primary Hypertension
- Definition: Chronic hypertension with no identifiable cause (essential hypertension).
- Risk Factors: Age, family history, obesity, sedentary lifestyle, high sodium intake.
- Symptoms: Asymptomatic unless severe.
- Diagnosis: Clinical diagnosis of exclusion.
- Treatment: Lifestyle changes, first-line medications (ACE inhibitors, ARBs, CCBs, thiazide diuretics).
Secondary Hypertension
- Definition: Hypertension caused by an underlying condition.
- Causes: Renovascular disease, endocrine disorders (pheochromocytoma, Cushing's syndrome, hyperaldosteronism), obstructive sleep apnea, coarctation of the aorta.
- Symptoms: Often resistant hypertension; may exhibit features of the underlying condition.
- Diagnosis: Workup for secondary causes (renal ultrasound, endocrine testing).
- Treatment: Treat the underlying cause; manage BP with appropriate medications.
Hypertensive Emergencies
- Definition: Severe hypertension (systolic BP ≥180 mmHg and/or diastolic BP ≥120 mmHg) with acute end-organ damage.
- Symptoms: Headache, chest pain, dyspnea, neurological deficits (stroke, encephalopathy), visual disturbances.
- Diagnosis: Blood pressure measurement; evidence of end-organ damage (labs, imaging).
- Treatment: Intravenous antihypertensives (labetalol, nitroprusside, nicardipine) to gradually lower BP over 24-48 hours to prevent ischemia.
Hypotension (Separate topic)
- Definition: Low blood pressure.
- (The provided text does not offer details on hypotension itself, so no further information is summarized regarding it.)*
