Randomized Controlled Trial
Diabetes and outcomes following guided de-escalation of antiplatelet treatment in acute coronary syndrome patients undergoing percutaneous coronary intervention: a pre-specified analysis from the randomised TROPICAL-ACS trial.
A guided de-escalation of P2Y12 inhibitor treatment is considered an alternative treatment strategy in ACS patients undergoing PCI. However, the safety and efficacy of this strategy may differ in diabetic vs non-diabetic patients. The aim of this study was to compare the outcomes of platelet function testing (PFT)-guided de-escalation of dual antiplatelet therapy (DAPT) in ACS patients with and without diabetes mellitus. ⋯ Although diabetic status did not significantly interfere with the treatment effects of guided DAPT de-escalation, our results suggest that this approach might be safe and effective in non-diabetic patients. Further investigation is definitely warranted in diabetic patients.

The aim of this study was to evaluate the Impella CP over veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and their impact on left ventricular unloading and end-organ perfusion. ⋯ In this porcine model of profound CS, Impella CP unloaded the left ventricle compared to VA-ECMO. Both devices improved end-organ perfusion, with a tendency towards higher venous oxygen saturations on VA-ECMO.

Randomized Controlled Trial
Comparison of everolimus-eluting bioresorbable vascular scaffolds and metallic stents: three-year clinical outcomes from the ABSORB China randomised trial.
Absorb bioresorbable vascular scaffolds (BVS) and XIENCE cobalt-chromium everolimus-eluting stents (CoCr-EES) had comparable angiographic and clinical outcomes up to one year in patients enrolled in the ABSORB China randomised trial. Whether these favourable results with BVS continue beyond one year up to three years is unknown. In this study we sought to analyse the outcomes from the trial up to three-year follow-up. ⋯ In the ABSORB China trial, BVS and CoCr-EES had similar results up to three-year follow-up, the time at which the scaffold has completely resorbed. BVS outcomes may be further optimised by appropriate lesion selection and implantation technique.

Current guidelines recommend an early invasive strategy in patients with non-ST-segment elevation acute coronary syndromes (NSTEACS). The role of an invasive strategy in frail elderly patients remains controversial. The aim of this substudy was to assess the impact of an invasive strategy on outcomes according to the degree of frailty in these patients. ⋯ An invasive strategy was independently associated with better outcomes in very elderly patients with NSTEACS. This association was different according to frailty status.
