Hypertension
A chronic elevation of blood pressure ≥130/80 mmHg (AHA 2017), a major modifiable risk factor for stroke, MI, and renal failure.
Primary (essential) hypertension accounts for 90–95% of cases. Lifestyle modification (DASH diet, exercise, sodium restriction) is first-line; pharmacotherapy is added when lifestyle changes are insufficient.
