Hypertension: spectrum of problems and guidelines for management.
Hypertensive patients may present to the emergency department with one of three general problems: high blood pressure due to labile hypertension, chronic hypertension, accelerated hypertension, or a hypertensive emergency; side effects from antihypertensive drugs; or acute medical or surgical illness whose management may be affected by hypertension or by drugs taken for hypertension. We describe these problems and recommend an approach to each that is appropriate in the emergency department.
