Randomized Controlled TrialElevated cardiac troponin T is associated with higher mortality and amputation rates in patients with peripheral arterial disease.
The aim of the present study was to evaluate whether elevated cardiac troponin T (cTnT) was independently associated with an increased all-cause mortality or risk of cardiovascular events and amputation among patients with peripheral arterial disease (PAD). ⋯ cTnT is frequently elevated in PAD patients and is associated with higher event rates in terms of total mortality and amputation. Even small cTnT elevations predict a markedly increased risk that is independent of an impaired renal function.

Randomized Controlled Trial Multicenter StudySex-related differences in outcomes after transcatheter or surgical aortic valve replacement in patients with severe aortic stenosis: Insights from the PARTNER Trial (Placement of Aortic Transcatheter Valve).
This study sought to examine sex-specific differences in outcomes after surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) in high-risk patients with severe aortic stenosis. ⋯ In this retrospective subanalysis of high-risk, symptomatic aortic stenosis patients in the PARTNER trial, female subjects had lower late mortality with TAVR versus SAVR. This was especially true among patients suitable for transfemoral access and suggests that TAVR may be preferred over surgery for high-risk female patients. A randomized, controlled trial conducted specifically in female patients is necessary to properly study differences in mortality between treatment modalities.

Randomized Controlled Trial Multicenter Study Comparative StudyA randomized comparison of drug-eluting balloon versus everolimus-eluting stent in patients with bare-metal stent-in-stent restenosis: the RIBS V Clinical Trial (Restenosis Intra-stent of Bare Metal Stents: paclitaxel-eluting balloon vs. everolimus-eluting stent).
This study sought to compare the efficacy of drug-eluting balloons (DEB) with that of everolimus-eluting stents (EES) in patients with bare-metal stents (BMS) in-stent restenosis (ISR). ⋯ In patients with BMS-ISR, both DEB and EES provided excellent clinical results with a very low rate of clinical and angiographic recurrences. However, compared with DEB, EES provide superior late angiographic findings.

Randomized Controlled Trial Multicenter StudyA prospective randomized trial of everolimus-eluting stents versus bare-metal stents in octogenarians: the XIMA Trial (Xience or Vision Stents for the Management of Angina in the Elderly).
The aim of this study was to determine whether drug-eluting stents (DES) are superior to bare-metal stents (BMS) in octogenarian patients with angina. ⋯ BMS and DES offer good clinical outcomes in this age group. DES were associated with a lower incidence of myocardial infarction and target vessel revascularization without increased incidence of major hemorrhage. (Xience or Vision Stent-Management of Angina in the Elderly [XIMA]; ISRCTN92243650).
