Takotsubo Cardiomyopathy in a Nonagenarian With Urosepsis

Takotsubo cardiomyopathy (TCM) is a rare but reversible myocardial left ventricular (LV) dysfunction, which mimics acute coronary syndrome (ACS) without the presence of significant coronary artery disease (CAD). Emotional stressors may include the death of kin or a life-threatening medical diagnosis whereas physical stressors include infections, endoscopic procedures, exacerbation of asthma, or systemic disorders. A 90-year-old female presented to the ED with nausea, intermittent chest heaviness, and generalized weakness for a duration of three days. Her troponin-I was elevated and an electrocardiogram (EKG) showed T-wave inversions in leads V2-V6 and no ST-segment changes. An echocardiogram (ECHO) revealed an ejection fraction (EF) of 35%-40% with anteroapical hypokinesis. She underwent cardiac catheterization showing nonobstructive CAD. She was diagnosed with pan-sensitive Escherichia coli urosepsis and started on ceftriaxone. She improved clinically and was discharged. A repeat ECHO done a month later showed normal EF. Urosepsis-induced TCM has rarely been reported in the literature. Physicians should have a high index of suspicion of TCM in patients with symptoms mimicking ACS in the presence of a physical stressor like an infection. We report the case of TCM, which resulted from a urinary tract infection (UTI) in an elderly female.
