Abstract
Perioperative takotsubo cardiomyopathy (pTCM) is an increasing condition defined as cardiomyopathy in the setting of emotional and physiologic stressors imposed by surgery. We aimed to classify and understand the presentation, management, and prognosis of noncardiac surgery pTCM in published cases. As such, a review of previous studies using the PubMed, Embase, Cochrane, and Web of Science databases was conducted to obtain case reports and series reporting noncardiac pTCM from inception to September 2022, and a crude analysis was conducted to classify the clinical features. Of the 1,002 studies, 96 met our inclusion criteria, of which 101 cases were extracted and included in the final systematic review. A total of 29.7% of cases occurred during general surgery and 20.8% during transplant procedures. The median age at presentation was 55 years, with a 42 to 65 interquartile range. The prevalence of hypertension and mood disorders were 22.8% and 9.9%, respectively. Before the procedures, physiologic stressors occurred more commonly than emotional stressors (20.8% and 11%, respectively). Objective findings, including ST-T-wave changes, new arrhythmias, and hypotension, were the most common initial presenting symptoms. Most cases occurred during emergence from surgery or on the first postoperative day. Mechanical circulatory support was required in 15.8% of the cases, and the all-cause in-hospital mortality was 6.9%. The ejection fraction and symptoms improved within a median of 2 weeks after diagnosis (interquartile range 1 to 6). In conclusion, the risk factors, triggers, and outcomes of pTCM appear to differ from those of classic nonperioperative TCM presentations. Future studies will help shed light on this more frequently diagnosed condition complicating some noncardiac surgical cases.
