The objective of this study was to prospectively compare changes in cardiac function over the acute and subacute phases after anterior STEMI with timely reperfusion in women versus men. The Stunning in Takotsubo versus Acute Myocardial Infarction (STAMI) study (NCT04448639) prospectively enrolled 105 men and 41 women with anterior STEMI. Echocardiography and blood sampling were performed within 4 hours of admission and at 1, 2, 3, 7, 14 and 30 days after admission. The primary outcome was akinesia recovery, defined as the difference in the percentage of akinesia observed at baseline versus follow-up. Secondary outcomes included wall motion score index (WMSI), left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS). Mixed effects linear regression or zero-inflated tobit models with random intercepts were used to model echocardiographic parameters over time. Baseline patient characteristics were similar in both groups. The difference between women and men in akinesia recovery at 30 days was 8.3% [95% credible interval 0.8%, 15.5%]. The covariate-adjusted posterior probability that akinesia recovery and WMSI improvement at 30 days are greater in women than men were 96.0% and 99.0% respectively. Similar but less pronounced trends towards greater improvement in women than men were observed for LVEF and GLS.

The BAN-ADHF score was incorporated into a diuretic dosing calculator and retroactively applied to a patient's diuretic dose to categorize them as adequately dosed or under-dosed (inadequate).
