Cerebral Infarction Arising from Takotsubo Cardiomyopathy: Case Report and Literature Review
Abstract
Although most patients with takotsubo cardiomyopathy have a favorable outcome, complications are not uncommon. Recent studies have reported an increase in incidence of cardioembolic complications; however, the association between takotsubo cardiomyopathy and stroke, in particular thromboembolic cerebral infarction, remains unclear. We reported a 44-year-old woman who had a cerebral infarction resulting from takotsubo cardiomyopathy. She had felt chest discomfort a few days prior to infarction, and later developed left hemiparesis. Head magnetic resonance imaging (MRI) revealed acute infarction in the right insular cortex and occlusion of the right middle cerebral artery at the M2 segment. Echocardiogram revealed a takotsubo-like shape in the motion of the left ventricular wall, and coronary angiography showed neither coronary stenosis nor occlusion. Cerebral infarction resulting from takotsubo cardiomyopathy was diagnosed and treatment with anticoagulant was started. MRI on the eighth day after hospitalization showed recanalization of the right middle cerebral artery and no new ischemic lesions. The findings of the 19 previously published cases who had cerebral infarction resulting from takotsubo cardiomyopathy were also reviewed and showed the median interval between takotsubo cardiomyopathy and cerebral infarction was approximately 1 week and cardiac thrombus was detected in 9 of 19 patients. We revealed that thromboembolic events occurred later than other complications of…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 9 participants or records.
