Echocardiography and blood sampling was performed within 4\u00a0h of admission and at 1, 2, 3, 7, 14, and 30\u00a0days after admission. The primary outcome was the proportion of reversible left ventricular akinesia (defined as extent of akinesia at baseline versus at 30\u00a0days) that resolved by 72\u00a0h. 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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At 72\u00a0h 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 \u2212\u00a04.6%, 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.
