ABSTRACT
AIMS:
Left ventricular ejection fraction (LVEF) recovery after an ST-segment elevation myocardial infarction (STEMI) identifies a group of patients with a better prognosis. However, the association between long-term outcomes and LVEF recovery among patients with STEMI undergoing primary percutaneous coronary intervention (PCI) has not yet been well investigated. Our study aims to detect differences in long-term all-cause and cardiovascular mortality between patients who recover LVEF at 1-year post-PCI and those who do not, and search for predictors of LVEF recovery. METHODS ANDRESULTS:
This is a retrospective, single-centre study of 2170 consecutive patients admitted for STEMI in which primary PCI is performed. LVEF was determined at admission and at 1-year follow-up. The primary outcomes were long-term all-cause and cardiovascular mortality. Among the 2168 patients with baseline LVEF data, 822 (38%) had a LVEF < 50% and 1346 (62%) ≥ 50%. Among those with LVEF < 50%, LVEF data at 1-year were available in 554, and 299 (54.0%) presented with complete recovery (LVEF ≥ 50%). LVEF recovery was associated with a reduction in long-term all-cause and cardiovascular mortality (P < 0.0001). Female sex, treatment with ACEIs, lower creatinine levels, infarct-related artery different from the left main or left anterior descendent artery, and absence of prior ischaemic heart disease were independently associated with LVEF recovery.CONCLUSIONS:
Nearly 40% of patients with STEMI undergoing primary PCI presented with LVEF depression at hospital admission. Among them, LVEF recovery at 1-year occurred in more than 50% and was independently associated with a significant decrease in long-term all-cause and cardiovascular mortality.Palabras clave
