Takotsubo cardiomyopathy in a female presenting with status asthmaticus: a case report and review of literature.

BACKGROUND

Takotsubo cardiomyopathy (TCM) is a non-ischemic syndrome characterized by transient acute left ventricular dysfunction as evident on transthoracic echocardiography. It can often mimic myocardial ischemia and is characterized by the absence of angiographic evidence of obstructive coronary artery disease. Reports of Takotsubo syndrome in elderly with asthma exacerbations have been noted.

CASE PRESENTATION

We describe a case of TCM in a 68-year-old female who presented with acute shortness of breath secondary to status asthmaticus. Her electrocardiogram showed ST segment elevations in multiple coronary artery distributions and mildly elevated troponin levels. Coronary angiography showed no significant stenosis of the coronary arteries with left ventriculography that showed systolic apical ballooning with a 10% ejection fraction, consistent with TCM.

CONCLUSIONS

Takotsubo syndrome should be considered in the differential diagnosis of patients presenting with status asthmaticus and elevated troponin levels on admission. Patients should be asked about the use of beta agonist prior to admission. A thorough literature review including a summary of 11 previously published case reports of TCM with acute asthma exacerbations has been presented.
