Issue Date: | 2021 | Publisher: | SPRINGER HEIDELBERG | Source: | Clinical research in cardiology (Print), 110 (9) , p. 1504 -1515 | Abstract: | Background Contemporary data on left ventricular function (LVF) recovery in patients with left ventricular dysfunction after ST-elevation myocardial infarction (STEMI) are scarce and to date, no comparison has been made with patients with a baseline normal LVF. This study examined predictors of LVF recovery and its relation to outcomes in STEMI.Methods Patients presenting with STEMI between January 2010 and December 2016 were categorized in three groups after 3 months according to left ventricular ejection fraction (EF): (i) baseline normal LVF (EF >= 50% at baseline); (ii) recovered LVF (EF < 50% at baseline and >= 50% after 3 months); and (iii) reduced LVF (EF < 50% at baseline and after 3 months). Heart failure hospitalization, all-cause mortality and cardiovascular mortality were compared between the three groups.Results Of 577 patients, 341 (59%) patients had a baseline normal LVF, 112 (19%) had a recovered LVF and 124 (22%) had a reduced LVF. Independent correlates of LVF recovery were higher baseline EF, lower peak troponin and cardiac arrest. After median 5.8 years, there was no difference in outcomes between patients with LVF recovery and baseline normal LVF. In contrast, even after multivariate adjustment, patients with persistently reduced LVF had a higher risk for heart failure hospitalization (HR 5.00; 95% CI 2.17-11.46) and all-cause mortality (HR 1.87; 95% CI 1.11-3.16). Conclusion In contemporary treated STEMI patients, prognosis is significantly worse in those with a persistently reduced LVF after 3 months, compared with patients with a baseline normal LVF and those with LVF recovery.[GRAPHICS]. | Keywords: | ST-elevation myocardial infarction;Left ventricular systolic dysfunction;Ejection fraction recovery;Heart failure hospitalization;Mortality | Document URI: | http://hdl.handle.net/1942/36298 | ISSN: | 1861-0684 | e-ISSN: | 1861-0692 | DOI: | 10.1007/s00392-021-01887-y | ISI #: | 000658126800001 | Rights: | Springer-Verlag GmbH Germany, part of Springer Nature 2021 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2022 |
