Surgical revascularization for acute coronary syndromes: a report from the North Rhine-Westphalia surgical myocardial infarction registry.

Objectives: The aim of this was to analyse current outcomes in patients referred to coronary artery bypass grafting (CABG) for acute coronary syndromes (ACSs), including ST-elevation or non-ST-elevation ACS (non-ST-segment elevation myocardial infarction) or unstable angina.

Methods: Patients (n = 2432) undergoing CABG for ACS between January 2010 and December 2017 were prospectively entered into a surgical myocardial infarction registry in North Rhine-Westphalia, Germany. Key end points were in-hospital all-cause mortality (IHM) and major adverse cardio-cerebral events (MACCE).

Reversible activation of nuclear factor-kappaB in human end-stage heart failure after left ventricular mechanical support.

Objective: Left ventricular assist devices (LVAD) have been used to 'bridge' patients with end-stage heart failure to transplantation. Although several reports have suggested that the native ventricular function recovers after long-term LVAD support, a process called 'reverse remodeling', the underlying biological mechanisms are still unknown. As the transcription factor nuclear factor-kappaB (NF-kappaB) has been shown to be active in the failing human heart, we examined whether its activity is altered under LVAD support, and may thus contribute to the dynamic process of 'reverse remodeling'.
