The emergency physician's disposition of @entity1 with suspected @entity741 is currently debated; some physicians believe that a subgroup of @entity1 can be managed safely outside the coronary care unit. Clinical predictors are needed in assessing the @entity1 with suspected @entity741 to help identify this subgroup. Through a retrospective cohort study, we investigated the value of the initial emergency department ECG in discriminating between @entity662 @entity1 with low and high risk for immediately life-threatening complications. Two hundred eleven initially uncomplicated consecutive coronary care unit admissions with suspected @entity1459 or @entity583 were studied. @entity1 outcome, including the incidence of @entity583 , complications, and mechanical and pharmacologic interventions, was reviewed. Immediately life-threatening complications included @entity2224 , @entity1165 , shock, 2 degrees and 3 degrees block, and @entity204 . Mechanical interventions included electrocardioversion or defibrillation, endotracheal intubation, intra-aortic balloon pump, Swan-Ganz catheter, or pacemaker insertion. Pressors, antiarrhythmics, and vasodilators were the reviewed pharmacologic interventions. A positive ECG was defined by the presence of ST elevation or @entity308 , T wave inversion, @entity4346 , @entity714 , paced rhythm, or new Q waves. All other ECG interpretations were considered negative. @entity1 were divided into two groups based on this initial emergency physician ECG interpretation and their complication incidences compared. Of the 211 @entity1 , 96 had a positive ECG; 115 had negative ECGs. @entity1 with positive ECGs were older, had a greater history and concurrent incidence of @entity583 , and more complications and intensive interventions.(ABSTRACT TRUNCATED AT 250 WORDS)
