Safety and feasibility of transradial access for percutaneous coronary intervention in chronic total occlusions.

INTRODUCTION AND OBJECTIVES: Transfemoral access is the most frequently used vascular approach in chronic total occlusion percutaneous coronary interventions (CTO-PCI). The aim of this study was to evaluate the safety and feasibility of a transradial access CTO-PCI program and its impact on angiographic and clinical results and length of hospital stay. METHODS: Retrospective multicenter cohort study including 2550 consecutive CTO-PCI procedures included in a multicenter registry with accurate information on vascular access. A total of 896 procedures were performed as radial-only access while 1654 were performed through at least 1 femoral puncture. Clinical and angiographic data were collected. RESULTS: The mean age was 66.3± 11.4 years. The mean Japan-chronic total occlusion score (2.7±0.3) was similar in the 2 groups. Successful revascularization was achieved in 2009 (79.6%) cases, 78.2% and 82.1% in the femoral and radial access cohorts, respectively (P=.002). Periprocedural in-hospital complications were observed in 5.1% and 2.3% (P=.02), with fewer access site-dependant vascular complications in the transradial cohort (2.3% vs 0.2%; P=.009). The mean length of hospital stay was significantly shorter in the transradial access group (0.89±1.4 vs 2.2±3.2 days, P<.001). CONCLUSIONS: A transradial program for CTO-PCI is safe and effective in most CTO lesions. The transradial strategy has fewer vascular complications and shorter length of hospital stay without compromising the success rate.

Effect of PCSK9 inhibitors on remnant cholesterol and lipid residual risk: The LIPID-REAL registry.

BACKGROUND: Monoclonal antibodies that inhibit the proprotein convertase subtilisin/kexin type 9 (PCSK9) reduce low-density lipoprotein cholesterol (LDLc) by 55%, regardless of baseline treatments. Nonetheless, the effect of other lipid parameters, such as cholesterol remnants or, the so-called lipid residual risk, is unknown. METHODS: Multicenter and retrospective registry of patients treated with PCSK9 inhibitors from 14 different hospitals in Spain. Before and on-treatment lipid parameters were recorded. Residual lipid risk was estimated by (1) cholesterol remnants, (2) triglycerides/HDLc ratio (TG/HDL), (3) total cholesterol/HDLc (TC/HDL) and (4) the triglycerides-to-glucose index (TGGi). RESULTS: Six hundred fifty-two patients were analysed, mean age of 60.2 (9.63) years, 24.69% women and mean LDLc before treatment 149.24 (49.86) mg/dl. Median time to second blood determination was 187.5 days. On-treatment LDLc was 67.46 (45.78) mg/dl, which represented a 55% reduction. Significant reductions were observed for TG/HDL ratio, cholesterol remnants, TC/HDL ratio and TGGi. As consequence, 34.61% patients had LDLc <55 mg/dl and cholesterol remnants <30 mg/dl; additionally, 31.95% had cholesterol remnants <30 mg/dl but LDLc >55 mg/dl. Patients who had levels of cholesterol remnants >30 mg/dl before initiating the treatment with PCSK9 had higher reductions in cholesterol remnants, TG/HDL ratio, TC/HDL and TGGi. By contrast, no reduction differences were observed according to baseline LDLc (< or > the mean), age, gender or obesity. CONCLUSIONS: This multicenter and retrospective registry of real-world patients treated with PCSK9 inhibitors demonstrates a positive effect on cholesterol remnants and lipid residual risk beyond LDLc reductions.

Seguridad y factibilidad de la intervención coronaria percutánea ambulatoria en pacientes seleccionados: datos de un registro multicéntrico español / Safety and feasibility of outpatient percutaneous coronary intervention in selected patients: a Spanish multicenter registry

Introducción y objetivos: El aumento exponencial de la intervención coronaria y la generalización del acceso radial son el escenario ideal para iniciar programas de angioplastia ambulatoria con el objetivo de disminuir ocupación y reducir el coste manteniendo la seguridad. Se presentan por primera vez datos de un registro multicéntrico español sobre angioplastia transradial ambulatoria en pacientes seleccionados. Métodos: Registro prospectivo de angioplastia ambulatoria electiva con acceso radial-cubital en pacientes con cardiopatía isquémica estable. Los pacientes eran dados de alta el mismo día y se realizó seguimiento a las 24 h y a los 30 días. Se analizan la seguridad y la factibilidad. Resultados: De un total de 723 pacientes incluidos (el 76% varones; edad, 66,6 ± 10,5 años), a 533 (73,7%) se les dio finalmente el alta tras 4-12 h de vigilancia. El motivo más frecuente de ingreso entre los 190 (26,7%) restantes fue inestabilidad clínica tras el procedimiento (60,5%). El antecedente de arteriopatía periférica, un valor de creatinina basal más elevado, la realización del procedimiento ad hoc y sobre enfermedad multivaso fueron predictores independientes de ingreso. A las 24 h se registró un evento adverso mayor (0,19%) en 1 paciente que necesitó ingreso por hemorragia mayor no relacionada con el acceso vascular. A los 30 días se registraron 3 eventos mayores (0,56%), 1 trombosis subaguda de stent, 1 revascularización sobre un vaso diferente del tratado y 1 ictus minor. A los 30 días habían necesitado ingreso 8 pacientes (1,5%). Conclusiones: La aplicación de un programa de angioplastia ambulatoria transradial-cubital con alta tras 4-12 h de vigilancia es factible y segura en pacientes apropiadamente seleccionados (AU)

Introduction and objectives: The exponential increase in coronary interventions plus the generalization of the radial approach represent the ideal scenario for starting outpatient angioplasty programs with the aim of reducing the costs while maintaining safety. This article reports data from a multicenter Spanish registry on fully ambulatory transradial angioplasty in selected patients for the first time. Methods: Prospective registry of elective outpatient transradial-ulnar angioplasty in patients with stable coronary disease. Patients were discharged the same day and were followed up at 24 hours and 30 days. Safety and feasibility were analyzed. Results: Of the 723 patients included (76% male; age, 66.6 ± 10.5 years), 533 (73.7%) were finally discharged after 4 to 12 hours of surveillance. Among the remaining 190 (26.7%) patients, the most common reason for hospitalization was clinical instability after the procedure (60.5%). Independent predictors of admission were a history of peripheral artery disease, a higher baseline creatinine level, ad hoc performance of the procedure, and multivessel disease. At 24 hours, there was 1 major adverse event in 1 patient (0.19%), who required hospitalization for major bleeding not related to vascular access. At 30 days, there were 3 major adverse events (0.56%): 1 subacute stent thrombosis, 1 revascularization of a vessel other than the treated vessel, and 1 minor stroke. Eight patients (1.5%) required admission at 30 days. Conclusions: The application of an outpatient transradial-ulnar angioplasty program with discharge after 4 to 12 hours’ surveillance is safe and feasible in well-selected patients (AU)
