Lustosa RP, Butcher SC, van der Bijl P, et al. - Researchers sought to determine the prognostic worth of global left ventricular (LV) myocardial work efficiency (GLVMWE; reflecting LV performance) obtained from pressure-strain loops with echocardiography in patients suffering from ST-segment–elevation myocardial infarction. They retrospectively examined 507 ST-segment–elevation myocardial infarction cases (mean age, 61±11 years; 76% males). According to findings, worse long-term survival was observed in relation to decreased GLVMWE (< 86%) determined by transthoracic echocardiography within 48 hours of admission in ST-segment–elevation myocardial infarction patients.
