How should we treat a hypertensive emergency?
Hypertensive emergencies are life-threatening situations caused by acute blood pressure elevation. They require immediate treatment with antihypertensive drugs. Such emergencies include hypertensive crisis, acute left ventricular heart failure or intracranial bleeding in patients with hypertension, malignant hypertension resistant to treatment, and serious blood pressure elevations after vascular surgery. A hypertensive crisis may be defined as a sudden increase in systolic and diastolic blood pressure that causes functional disturbances of the central nervous system, the heart or the kidneys. In patients with hypertensive crisis, treatment should be started with an alpha receptor-blocking agent if pheochromocytoma has not been excluded by previous workup. Antihypertensive agents with a rapid onset of action--nifedipine, clonidine, dihydralazine, diazoxide and sodium nitroprusside--are being used.
