A Case Report of Takotsubo Cardiomyopathy With Dengue

A 74-year-old woman with well-controlled hypertension and dyslipidemia with acute fever was diagnosed with dengue infection. She had non-anginal central chest pain which was associated with ST elevation and T inversions in V1 to V6 with prolonged QT interval. Her high-sensitivity troponin was elevated. There was echocardiographic evidence of severe left ventricular dysfunction (ejection fraction 35%; Simpson method) with apical ballooning suggestive of takotsubo cardiomyopathy. No left ventricular basal hyperkinesia was noted. The patient was managed as per the national dengue guidelines of Sri Lanka. Her cardiac condition was managed conservatively. She did not experience dengue complications such as dengue shock syndrome or dengue hemorrhagic fever or pulmonary edema secondary to severe LV dysfunction. The clinical symptoms and echocardiographic findings of takotsubo cardiomyopathy resolved parallel to dengue fever.
