Electrocardiographic ST-segment elevation: Takotsubo cardiomyopathy versus ST-segment elevation myocardial infarction--a case series.
Takotsubo cardiomyopathy, or left ventricular apical ballooning syndrome, is a newly described disorder in which patients develop anginal symptoms, often times with acute congestive heart failure, during periods of stress. The electrocardiogram demonstrates ST-segment and/or T-wave abnormalities similar to those findings seen in acute coronary events; on occasion, serum markers can be abnormal. As an extreme, acute pulmonary edema with or without cardiogenic shock can also be encountered. At cardiac catheterization, these patients are found to have abnormal left ventricular function yet normal coronary arteries. We compared 2 populations encountered in the emergency department (ED) population--Takotsubo cardiomyopathy and ST-segment elevation myocardial infarction. In the ED, features of the presentation and management were similar between the 2 groups with the exception of the presence of female sex and abnormal QT interval occurring more often in Takotsubo cardiomyopathy subgroup. These 2 cardiovascular maladies present in very similar fashion in the ED; distinction in the ED may not be possible.
