Long-Term Outcomes After Percutaneous Coronary Intervention for Chronic Total Occlusion (from the CREDO-Kyoto Registry Cohort-2)
Despite improving success rate of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions, the clinical benefit of recanalization of CTO is still a matter of debate. Of 13,087 patients who underwent PCI in the CREDO-Kyoto registry cohort-2, 1,524 patients received PCI for CTO (CTO-PCI). Clinical outcomes were compared between 1,192 patients with successful CTO-PCI and 332 patients with failed CTO-PCI. In-hospital death tended to occur less frequently in the successful CTO-PCI group than in the failed CTO-PCI group (1.4% vs 3.0%, p = 0.053).Comparison of Outcomes Using the Sirolimus-Eluting Stent in Calcified Versus Non-Calcified Native Coronary Lesions in Patients On- Versus Not On-Chronic Hemodialysis (from the j-Cypher Registry)
The impact of lesion calcium on long-term outcomes after drug-eluting stent implantation has not been adequately addressed. In 10,595 patients (16,803 lesions) who were exclusively treated with sirolimus-eluting stents in the j-Cypher registry, 5-year outcomes were compared between patients with ≥1 lesion with moderate or severe calcification (the calcium group) and those with noncalcified lesions only (the noncalcium group). Analyses were stratified by hemodialysis (HD) status (non-HD stratum [calcium n = 3,191, noncalcium n = 6,824] and HD stratum [calcium n = 415, noncalcium n = 165]).Comparison of Long-Term Outcome After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting in Patients With Unprotected Left Main Coronary Artery Disease (from the CREDO-Kyoto PCI/CABG Registry Cohort-2)
The long-term outcome of percutaneous coronary intervention (PCI) compared to coronary artery bypass grafting (CABG) for unprotected left main coronary artery disease (ULMCAD) remains to be investigated. We identified 1,005 patients with ULMCAD of 15,939 patients with first coronary revascularization enrolled in the CREDO-Kyoto PCI/CABG Registry Cohort-2. Cumulative 3-year incidence of a composite of death/myocardial infarction (MI)/stroke was significantly higher in the PCI group than in the CABG group (22.7% vs 14.8%, p = 0.0006, log-rank test).Safety and Efficacy of Sirolimus-Eluting Stent Implantation in Patients With Acute Coronary Syndrome in the Real World
The use of drug-eluting stents in patients with acute coronary syndrome (ACS), particularly those with acute myocardial infarction (AMI), is controversial owing to concerns about late adverse events. We evaluated the long-term safety of sirolimus-eluting stent implantation in patients with ACS. Of 10,778 patients treated exclusively with a sirolimus-eluting stent in the j-Cypher registry, the 3-year outcomes of 2,308 patients with ACS (953 patients with AMI) were compared to those of 8,470 patients without ACS.
