Ultrathin-strut versus thin-strut stent healing and outcomes in preclinical and clinical subjects.

Background: Compared with thin-strut durable-polymer drug-eluting stents (DP-DES), ultrathin-strut biodegradable-polymer sirolimus-eluting stents (BP-SES) improve stent-related clinical outcomes in patients undergoing percutaneous coronary intervention (PCI). Reduced stent strut thickness is hypothesised to underlie these benefits, but this conjecture remains unproven.

Aims: We aimed to assess the impact of strut thickness on stent healing and clinical outcomes between ultrathin-strut and thin-strut BP-SES.

Variation in Survival After Cardiopulmonary Arrest in Cardiac Catheterization Laboratories in the United States.

Background: In-hospital cardiac arrest during cardiac catheterization is not uncommon. The extent of variation in survival after cardiac arrest occurring in the cardiac catheterization laboratory (CCL) and underlying factors are not well known.

Objectives: The aim of this study was to identify the factors associated with higher survival rates after an index cardiac arrest in the CCL.
