Takotsubo Cardiomyopathy With Markedly Elevated Troponin Triggered by Acute Psychosis: A Case Report
Abstract
Takotsubo cardiomyopathy (TTC) is an acute, reversible form of left ventricular dysfunction that mimics acute coronary syndrome (ACS), typically presenting with modest troponin elevation. We report a 38-year-old woman with a history of depression, who presented with acute psychosis requiring haloperidol sedation. Routine ECG monitoring revealed inferolateral ST-segment elevation, although she was asymptomatic at presentation and recalled only a non-specific burning chest discomfort three days prior. Laboratory tests demonstrated markedly elevated troponin I (>24,000 ng/L) and creatine kinase (5,931 U/L), unusual for TTC and suggestive of ACS. Bedside echocardiography revealed severe left ventricular systolic dysfunction with apical akinesia (ejection fraction (EF) ~35%), while coronary CT angiography showed unobstructed coronary arteries and a zero calcium score, confirming TTC. She was managed conservatively in the coronary care unit with bisoprolol and dapagliflozin, and psychiatric input guided safe antipsychotic use. Follow-up echocardiography demonstrated improvement in left ventricular function (EF 45%-49%), with resolution of symptoms. This case highlights the rare occurrence of TTC with disproportionately high troponin levels and underscores the importance of multimodal imaging and multidisciplinary management in patients with psychiatric comorbidities to avoid misdiagnosis and unnecessary invasive procedures.
