Long-Term Outcomes After Coronary Stent Implantation in Patients Presenting With Versus Without Acute Myocardial Infarction (an Observation from Coronary Revascularization Demonstrating Outcome Study-Kyoto Registry Cohort-2)
It has not been adequately addressed yet how long the excess cardiovascular event risk persists after acute myocardial infarction (AMI) compared with stable coronary artery disease. Of 10,470 consecutive patients who underwent percutaneous coronary intervention either with sirolimus-eluting stent (SES) only or with bare-metal stent (BMS) only in the Coronary Revascularization Demonstrating Outcome Study-Kyoto Registry Cohort-2, 3,710 (SES: n = 820 and BMS: n = 2,890) and 6,760 patients (SES: n = 4,258 and BMS: n = 2,502) presented with AMI (AMI group) and without AMI (non-AMI group), respectively.Effect of Preinfarction Angina Pectoris on Long-term Survival in Patients With ST-Segment Elevation Myocardial Infarction Who Underwent Primary Percutaneous Coronary Intervention
The influence of preinfarction angina pectoris (AP) on long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) remains controversial. In 5,429 patients with acute myocardial infarction (AMI) enrolled in the Coronary Revascularization Demonstrating Outcome Study in Kyoto AMI Registry, the present study population consisted of 3,476 patients with STEMI who underwent primary PCI within 24 hours of symptom onset and in whom the data on preinfarction AP were available.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).
