ABSTRACT
About 65 million Americans, one fourth of the adult population in the United States, and over 1 billion people worldwide have hypertension (HTN). HTN therefore is present in 1 of every 4 patients admitted to any US hospital. Surprisingly, no guidelines are available for the management of inpatient HTN. Based on a comprehensive search of the literature we are proposing a pathway for the management of HTN in nonpregnant hospitalized patients. The pathway provides a definition and clinical assessment of HTN for patients admitted to the hospital. The assessment is followed by an organ/system based therapeutic approach specifying timing, blood pressure goals, recommended antihypertensive drug therapy and the sequence of add-on drugs. The pathway specifically discusses assessment and management of HTN in patients with (1) acute aortic syndrome, (2) acute neurologic syndrome, (3) acute coronary syndrome, (4) congestive heart failure, (5) renal failure, and (6) secondary forms. Finally, the pathway provides a step by step recommendation for the management of in hospital HTN and of hypertensive emergencies.

A 71-year-old woman who had critical cerebral ischemia secondary to a carotid artery occlusion was receiving high-dose intravenous phenylephrine for a trial of hypertensive therapy. While on a maximal dose of phenylephrine she developed prominent positive U waves, which disappeared with the cessation of the drug. The possible underlying electrophysiological mechanisms of this phenomenon are discussed in this paper.
