Prospective Comparison of Temporal Myocardial Function in Men Versus Women After Anterior ST-Elevation Myocardial Infarction With Timely Reperfusion.

Compared to men, women have been reported to have increased morbidity and mortality after ST-elevation myocardial infarction (STEMI); but sex differences in cardiac function in the acute and subacute phases of STEMI are incompletely understood. 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.
