Backgroud Although procedural success rates are similar by sex, it remains unclear whether long-term outcomes exist between the sexes. Methods Data on 1900 Chinese patients from a registry evaluating safety and effectiveness of everolimus drug eluting stent for coronary revascularisation (SEEDS) were analysed to compare long-term outcomes by sex. Results Female patients (n = 492) were older (63.27 ± 8.38 vs 58.38 ± 9.55, p 0.05), myocardial infarction (3.25% vs 3.48%, p > 0.05), stent thrombosis (0.41% vs 0.64%, p > 0.05) and bleeding (1.22% vs 1.49%, p > 0.05) was lower in female patients. Conclusions Women undergoing everolimus drug eluting stent implantation have a slightly higher risk than men, but have better long-term survival, especially for rate of target vessel failure.

Introduction There are limited data on the impact of successful chronic total occlusion (CTO) revascularisation by percutaneous coronary intervention (PCI) on long-term outcomes. Methods Between June 1993 and December 2006, a total of 1332 patients having PCI for a CTO were consecutively registered. In addition to an assessment of procedural outcomes, patients were followed long-term for occurrence of major adverse cardiac events (MACE). A CTO was defined as an occlusion of the artery present for at least 3 months with Thrombolysis in Myocardial Infarction flow grade 0 or 1. Long-term survival rate was estimated by Kaplan-Meier methods. Results The overall success rate was 90.2% (1202/1332). During a median follow-up of 6.26±2.52 years (median 6 years), the estimated 10-year survival rate was 76.7% in the CTO success patients and 65.5% in the CTO failure patients, respectively (p Conclusions Successful revascularisation for CTO improves long-term survival and reduces MACE rate and the need for CABG compared with failed procedure.
