Clinical Studies Reporting on Vascular Graft Coatings for the Prevention of Aortic Graft Infection: A Systematic Review and Meta-Analysis.

Objective: The aim of this study was to investigate the efficacy of vascular graft coatings used in the aortic position to prevent vascular graft infection (VGI).

Methods: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines using a pre-registered protocol (CRD42020206436). Eligible studies used a vascular graft coating in the aortic position and reported on VGI.

Left ventricular function recovery after ST-elevation myocardial infarction: correlates and outcomes.

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).
