RESUMEN
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.

BACKGROUND AND OBJECTIVE: There are limited data regarding the need for intensive care or the appropriate length of hospital stay for patients with ST elevation acute myocardial infarction (STEMI). In order to optimize resources, we tried to determine the need of coronary care unit (CCU) admission for patients with STEMI who remained in Killip class I after a successful primary percutaneous coronary intervention (PPCI). METHODS: From August of 2006 till June of 2008, we analyzed data from all patients admitted in our CCU who met these criteria, a total of 278. We prospectively recorded all in-hospital adverse events and event-free survival at 30 and 90 days (all cause death, stroke, new acute coronary syndrome or re-hospitalization due to heart failure). Medical treatment was optimized according to the current guidelines. RESULTS: A coronary stent was implanted in 96% of the patients. None of the patients had any adverse event that could not be resolved in a step-down unit. Survival at 30 and at 90 days was 99.6% and 98.3% respectively. Event-free survival was 97.3% at 30 days and 94.3% at 90 days. The median length of stay was three days in the CCU and five days in the hospital. CONCLUSION: Patients with STEMI treated with PPCI who remained in Killip class I after the procedure and receive optimal pharmacological treatment have an excellent prognosis. All of them can probably be admitted safely to a step-down unit. Wide application of this management strategy may result in substantial cost savings.
