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.Comparison of Five-Year Outcome of Percutaneous Coronary Intervention With Coronary Artery Bypass Grafting in Triple-Vessel Coronary Artery Disease (from the Coronary Revascularization Demonstrating Outcome Study in Kyoto PCI/CABG Registry Cohort-2)
Studies evaluating long-term (≥5 years) outcomes of percutaneous coronary intervention (PCI) using drug-eluting stents compared with coronary artery bypass grafting (CABG) in patients with triple-vessel coronary artery disease (TVD) are still limited. We identified 2,978 patients with TVD (PCI: n = 1,824, CABG: n = 1,154) of 15,939 patients with first coronary revascularization enrolled in the Coronary Revascularization Demonstrating Outcome Study in Kyoto PCI/CABG Registry Cohort-2. The primary outcome measure in the present analysis was a composite of death, myocardial infarction (MI), and stroke.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 Mortality After Acute Myocardial Infarction Treated by Percutaneous Coronary Intervention in Patients Living Alone Versus Not Living Alone at the Time of Hospitalization
Living alone was reported to be associated with increased risk of cardiovascular disease. There are, however, limited data on the relation between living alone and all-cause mortality in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). The Coronary REvascularization Demonstrating Outcome Study in Kyoto (CREDO-Kyoto) AMI registry was a cohort study of patients with AMI enrolled in 26 hospitals in Japan from 2005 through 2007. For the current analysis, we included those patients who underwent PCI within 24 hours of symptom onset, and we assessed their living status to determine if living alone would be an independent prognostic risk factor.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).Renal Function and Effect of Statin Therapy on Cardiovascular Outcomes in Patients Undergoing Coronary Revascularization (from the CREDO-Kyoto PCI/CABG Registry Cohort-2)
Although statin therapy is essential for secondary cardiovascular prevention, the therapeutic effect of statins on cardiovascular outcomes in patients with advanced chronic kidney disease (CKD) after coronary revascularization has not been fully elucidated. In the CREDO-Kyoto Registry Cohort-2, 14,706 patients who underwent first coronary revascularization were divided into 4 strata based on estimated glomerular filtration rate (eGFR) or status of hemodialysis (HD). Patients in each stratum were further divided into 2 groups based on statin therapy at discharge: non-CKD stratum (eGFR ≥60 ml/min/1.73 m2), 8,959 patients (statin, n = 4,747; no statin, n = 4,212); mild CKD stratum (eGFR ≥30 to <60 ml/min/1.73 m2), 4,567 patients (statin, n = 2,135; no statin, n = 2,432); severe CKD stratum (eGFR <30 ml/min/1.73 m2), 608 patients (statin, n = 229; no statin, n = 379); and HD stratum, 572 patients (statin, n = 117; no statin, n = 455).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).Impact of Statin Therapy on Late Target Lesion Revascularization After Sirolimus-Eluting Stent Implantation (from the CREDO-Kyoto Registry Cohort-2)
Therapeutic strategies preventing late target lesion revascularization (TLR) after drug-eluting stent implantation have not been yet adequately investigated. In 13,087 consecutive patients undergoing first percutaneous coronary intervention in the CREDO-Kyoto Registry Cohort-2, we identified 10,221 patients who were discharged alive after implantation of sirolimus-eluting stents (SESs) only (SES stratum 5,029) or bare-metal stents (BMSs) only (BMS stratum 5,192). Impact of statin therapy at time of discharge from the index hospitalization on early (within the first year) and late (1 year to 4 years) TLR, was assessed in the SES stratum (statin group 2,735; nonstatin group 2,294) and in the BMS stratum (statin group 2,576; nonstatin group 2,616).
