Background: A polymer-free biolimus A9-coated stent (PF-BCS) may achieve better arterial healing than a durable polymer drug-eluting stent owing to its polymer-free feature.Methods and Results: This multicenter, prospective, observational study enrolled 105 patients (132 lesions) who underwent PF-BCS (51 patients, 71 lesions) or durable polymer everolimus-eluting stent (DP-EES, 54 patients, 61 lesions) implantation. Serial coronary angioscopy (CAS) and optical coherence tomography (OCT) examinations were performed at 1 and 12 months, and the serial vessel responses were compared between PF-BCS and DP-EES. The primary outcome measure was the incidence of subclinical intrastent thrombus on CAS. The secondary outcome measures were: adequate strut coverage (≥40 μm) on OCT and maximum yellow color grade on CAS. The incidence of thrombus was high at 1 month (100% vs. 93%, P=0.091), but decreased at 12 months (18% vs. 25%, P=0.56), without a significant difference between PF-BCS and DP-EES. The adequate strut coverage rate was significantly higher (84±14% vs. 69±22%, P<0.001) and yellow color was significantly less intense (P=0.012) at 12 months in PF-BCS than in DP-EES; however, they were not significantly different at 1 month (adequate strut coverage: 47±21% vs. 50±17%, P=0.40; yellow color: P=0.99).Conclusions: Although the thrombogenicity of PF-BCS was similar to that of DP-EES, the adequate coverage and plaque stabilization rates of PF-BCS were superior to those of DP-EES at 12 months.

Background:The purpose of this study was to elucidate the effect of the temporal relationship between atrial fibrillation (AF) and heart failure (HF) on clinical outcomes after catheter ablation.Methods and Results:We included 129 consecutive patients with AF and HF who underwent catheter ablation in hospital from December 2014 to September 2017. The patients were divided into 2 groups based on the temporal relationship between AF and HF. Group 1 consisted of 42 patients with AF following HF while Group 2 consisted of 87 patients with AF preceding HF or those who developed both of them simultaneously at the timing of first visit to a doctor. The primary endpoint was a composite of death and hospitalization due to HF during a 2-year follow-up. AF recurrence was more common in Group 1 (45% vs. 23%; hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.25–4.94; P=0.009). Death and HF hospitalization were more frequent in Group 1 (19 [45%], 6 [7%] patients, respectively, P<0.0001). After adjustment for several covariates, patients in Group 1 were independently associated with poorer outcomes after AF ablation (HR, 8.66; 95% CI, 2.942–5.5; P<0.0001).Conclusions:Adverse clinical outcomes of death, HF hospitalization and AF recurrence were more frequent in patients with AF following HF than in those with AF preceding HF.

Aims: This study aimed to investigate the long-term impact of guideline-directed medical therapy (GDMT) on 10-year mortality in patients with chronic limb-threatening ischaemia (CLTI) after revascularization. Methods: We performed a retrospective multicentre study enrolle 459 patients with CLTI who underwent revascularization (396 endovascular therapy [EVT] and 63 bypass surgery [BSX] cases) between January 2007 and December 2011. The primary outcome measure was all-cause mortality. We additionally explored the predictors for all-cause mortality using Cox regression hazard models; the influence of GDMT, defined as prescription of antiplatelet agents, statins, and angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) in aggregate, on all-cause mortality, and the association between baseline characteristics using interaction effects. Results: During the 10-year follow-up after revascularization, 234 patients died. In Kaplan-Meier analysis, 10-year mortality was significantly lower in patients who received statins (p<.001) and ACE inhibitors or ARBs (p=.010) than those who did not. However, there were no differences in 10-year mortality between patients who received anti-platelet agents and those who did not (p=.62). Interaction analysis revealed that GDMT had a significantly different hazard ratio in patients who were and were not on hemodialysis and in those treated with EVT or BSX (p for interaction =.002 and .044, respectively). In the multivariate analysis, age >75 years, non-ambulatory status, hemodialysis, congestive heart failure, left ventricular ejection fraction <50%, and GDMT were significantly associated with all-cause mortality. Conclusions: Appropriate GDMT use was independently associated with 10-year mortality in patients with CLTI after revascularization.
