BACKGROUND:Limited data are available on the care of patients with acute severe hypertension requiring hospitalization. We characterized contemporary practice patterns and outcomes for this population. METHODS:STAT is a 25-institution, US registry of consecutive patients with acute severe hypertension (>180 mm Hg systolic and/or >110 mm Hg diastolic; >140 and/or >90 for subarachnoid hemorrhage) treated with intravenous therapy in a critical care setting. RESULTS:One thousand five hundred eighty-eight patients were enrolled (January 2007 to April 2008). Median age was 58 years (interquartile range 49-70 years), 779 (49%) were women, and 892 (56%) were African American; 27% (n = 425) had a prior admission for acute hypertension and 486 (31%) had chronic kidney disease. Median qualifying blood pressure (BP) was 200 (186, 220) systolic and 110 (93, 123) mm Hg diastolic. Initial intravenous antihypertensive therapies used to control BP varied, with 1,009 (64%) patients requiring multiple drugs. Median time to achieve a systolic BP <160 mm Hg (<140 mm Hg for subarachnoid hemorrhage) was 4.0 (0.8, 12) hours; 893 (60%) had reelevation to >180 (>140 for subarachnoid hemorrhage) after initial control; and 63 (4.0%) developed iatrogenic hypotension. Hospital mortality was 6.9% (n = 109) with an aggregate 90-day mortality rate of 11% (174/1,588); 59% (n = 943) had acute/worsening end-organ dysfunction during hospitalization. The 90-day readmission rate was 37% (523/1,415), of which one quarter (132/523) was due to recurrent acute severe hypertension. CONCLUSION/CONCLUSIONS:This study highlights heterogeneity in care, BP control, and outcomes of patients hospitalized with acute severe hypertension.

With an aging U.S. population and a declining physician supply, the care of critically ill patients will soon be reaching a level of crisis. At the same time, the evidence continues to mount in support of intensivist staffing to improve both patient outcomes and resource utilization in intensive care units (ICUs). Whereas the vast majority of medical and surgical ICUs are staffed by physicians trained in critical care medicine, that is not commonly the case in coronary care units (CCUs) in this country. Despite that, the breadth and diversity of comorbidities in patients that occupy our CCU beds is continuously growing. No longer is the CCU merely an observation unit for peri-infarction complications, but rather it has truly become an ICU for patients with cardiovascular disease. With this in mind, there becomes a growing need for intensivist-trained cardiologists and a push for the development of critical care training pathways in our cardiovascular fellowship programs.
