Impacto del acceso vascular en el pronóstico tras la angioplastia coronaria en pacientes con alto riesgo hemorrágico: subanálisis predefinido del estudio LEADERS FREE / Impact of vascular access on outcome after PCI in patients at high bleeding risk: a pre-specified sub-analysis of the LEADERS FREE trial

INTRODUCCIÓN Y OBJETIVOS: El objetivo es evaluar el impacto del acceso vascular en las complicaciones hemorrágicas tras una intervención coronaria percutánea en pacientes con alto riesgo de sangrado (ARS) a los 30 días y a los 2 años. MÉTODOS: El presente estudio es un subanálisis predefinido del estudio LEADERS FREE, que incluyó a 2.432 pacientes con ARS y en el que el stent farmacoactivo Biolimus A9 resultó superior al stent convencional en seguridad y eficacia. RESULTADOS: El acceso radial (AR) se utilizó en 1.454 pacientes (59,8%) y el femoral (AF), en 978 (40,2%), ambos a elección del operador. La seguridad y los beneficios del stent farmacoactivo sobre el convencional fueron independientes del acceso vascular. A los 30 días y a los 2 años, habían sufrido un sangrado mayor el 2,4 y el 7,5% de los pacientes con AR y el 4,6 y el 10,9% de los pacientes con AF (p = 0,003), la mayoría en ambos grupos (el 2,1 y el 7,0% del de AR; el 3,2 y el 9,4% del de AF) no relacionados con el sitio de acceso vascular. El AR se asoció con una reducción significativa en las tasas ajustadas de sangrado mayor tanto a 30 días (HR=1,98; IC95%, 1,25-3,11; p = 0,003) como a 2 años de seguimiento (HR=1,51; IC95%, 1,14-2,01; p = 0,003). CONCLUSIONES: Los operadores prefirieron el AR en la mayoría de los pacientes con ARS, lo cual se asoció con una reducción significativa del sangrado mayor. Asimismo, un número significativo de sangrados en el seguimiento de esta población son no relacionados con el acceso vascular

INTRODUCTION AND OBJECTIVES: The prognostic impact of bleeding in high bleeding risk (HBR) patients depending on the location of bleeding and prognosis in nonaccess site bleeding is unknown. We aimed to assess the impact of vascular access site on bleeding complications after percutaneous coronary interventions for HBR patients at 30-day and 2-year follow-up. METHODS: The LEADERS FREE trial included 2432 HBR PCI patients. A Biolimus A9 drug-coated stent was superior to a bare-metal stent for safety and efficacy. This is a predefined sub-analysis of the LEADERS FREE trial. RESULTS: Transradial access (TRA) was used in 1454 patients (59.8%) and transfemoral access (TFA) in 978 (40.2%), according to operator preference. The safety and benefits of drug-coated stents over bare-metal stents were independent of vascular access. At 30 days and 2 years, major bleeding had occurred in 2.4% and 7.5% of TRA patients and 4.6% and 10.9% of TFA patients (P=.003), respectively. Most of these events in both groups (2.1% and 7.0% for TRA; 3.2% and 9.4% for TFA, respectively) were nonaccess site-related. TRA was associated with a significant reduction in adjusted rates of major bleeding both at 30 days (HR, 1.98; 95%CI, 1.25-3.11; P=.003) and at 2 years of follow-up (HR, 1.51; 95%CI, 1.14-2.01; P=.003). This difference was driven by both access and nonaccess bleeding. CONCLUSIONS: Operators preferred TRA for most HBR patients, which was associated with a significant reduction in major bleeding events. However, most of these events in this population are unrelated to vascular access

One-year clinical outcome of biodegradable polymer sirolimus-eluting stent in all-comers population. Insight from the ULISSE registry (ULtimaster Italian multicenter all comerS Stent rEgistry).

BACKGROUND: This study was designed to confirm in a large population of unselected patients the promising results of Ultimaster® biodegradable polymer sirolimus-eluting stent (BP-SES) already shown in previous trial. METHODS: ULISSE is an observational, multicenter, national registry evaluating all patients undergoing PCI with the Ultimaster® BP-SES. Incidence of 1-year TLF (cardiac death or target vessel MI or clinically indicated TLR) was the primary endpoint. Pre-specified subgroup analysis was performed for diabetic patients and for those with lesion longer than 25 mm, bifurcation and CTO lesions. RESULTS: 1660 patients were enrolled in 9 Italian cardiology centers, 82% were males, mean age of 68 ±â€¯10 years, and 29% were diabetics. Overall 2422 lesions were treated, 65% type B2/C lesions, 7% CTOs, 17% bifurcations and 38% long lesions. The incidence of 1-year TLF was 5%, with 3.2% of clinically indicated TLR. TLF occurred in 8% of the patients with diabetes mellitus, and 7% in bifurcation, 6.7% in CTO and 6.2% in long lesions. Definite overall ST was 0.9%, and 1.2% in patients treated for type B2/C lesions. Multivariate logistic regression analysis identified stenting on unprotected LMT (OR = 4.80), stenting on ISR lesion (OR = 3.19) and need for rotational atherectomy (OR = 6.24) as the strongest independent predictors of TLF. CONCLUSIONS: The results of this national all-comers registry show that the Ultimaster® BP-SES real-world performance was comparable with that observed in the clinical trial, with low rate of primary endpoint and TLR. Long term follow-up will be necessary to prove the theoretical advantage of the BP-SES over time.
