Abstract
Background: Takotsubo syndrome (TS) and STEMI with timely reperfusion are both characterized by reversible acute myocardial dysfunction, often referred to as myocardial stunning. The natural course of cardiac functional recovery is incompletely understood in TS and STEMI. The aim of this study was to prospectively compare changes in cardiac function over the acute and subacute phases in women with TS versus anterior STEMI.
Methods: The Stunning in Takotsubo versus Acute Myocardial Infarction (STAMI) study prospectively enrolled 61 women with TS and 41 women with STEMI. Echocardiography and blood sampling was performed within 4 h of admission and at 1, 2, 3, 7, 14, and 30 days after admission. The primary outcome was the proportion of reversible left ventricular akinesia (defined as extent of akinesia at baseline versus at 30 days) that resolved by 72 h. Secondary outcomes included LVEF, GLS, and TAPSE. Mixed effects linear regression or mixed effects tobit models with random intercepts were used to model echocardiographic parameters over time.
Results: At 72 h 40.4% [95% CI 30.1%, 50.1%] of the reversible akinesia had resolved in women with TS, versus 54.7% [95% CI 38.3%, 72.0%] for STEMI (difference 14.3% [95% CI - 4.6%, 34.3%]). Time-course of recovery of LVEF and GLS was also similar in TS and STEMI. TAPSE was reduced in TS but normal in STEMI; and recovered in a similar timeframe as the left ventricular indices. In both TS and STEMI, considerable recovery of cardiac function occurred after 7 days.
Conclusions: The time course of recovery of cardiac function is similar in TS and STEMI.

期刊介绍：
Clinical Research in Cardiology is an international journal for clinical cardiovascular research. It provides a forum for original and review articles as well as critical perspective articles. Articles are only accepted if they meet stringent scientific standards and have undergone peer review. The journal regularly receives articles from the field of clinical cardiology, angiology, as well as heart and vascular surgery.
As the official journal of the German Cardiac Society, it gives a current and competent survey on the diagnosis and therapy of heart and vascular diseases.
