Arterial plaque rupture and thrombus characterise ST-elevation myocardial infarction (STEMI) and may aggravate delayed arterial healing following durable polymer drug-eluting stent (DP-DES) implantation. Biodegradable polymer (BP) may improve biocompatibility. We compared long-term outcomes in STEMI patients receiving BP-DES vs. durable polymer sirolimus-eluting stents (DP-SES). ⋯ In STEMI, BP-DES demonstrated superior clinical outcomes to DP-SES at four years. Trends towards reduced cardiac death or myocardial infarction and reduced stent thrombosis require corroboration in specifically powered trials.

To investigate the effects of clopidogrel and eptifibatide on platelet reactivity in patients resuscitated from cardiac arrest undergoing percutaneous coronary intervention (PCI) and hypothermia. ⋯ Post-resuscitation syndrome with ongoing hypothermia is associated with decreased platelet reactivity. Clopidogrel loading does not significantly affect platelet function during the first 48 hours. This is in contrast with eptifibatide which produces profound platelet inhibition, and may be used to bridge insufficient inhibition by clopidogrel.

Transcatheter aortic valve implantation (TAVI) is an alternative therapeutic option for patients with severe aortic valve stenosis (AS) and elevated surgical risk. Previous studies have suggested that the occurrence of systemic inflammatory response syndrome (SIRS) in patients undergoing TAVI is associated with an unfavourable outcome. We sought to assess the impact of different interventional access routes (transapical [TA] vs. transfemoral [TF]) and valve types (Medtronic CoreValve® [CV] vs. Edwards SAPIEN XT® [ES]) on the incidence of SIRS. In addition, the prognostic value of SIRS was evaluated. ⋯ The occurrence of SIRS in the first 48 hours post procedure is associated with impaired prognosis following TAVI, but is independent from the chosen valve type and access route.
