Journal Article
Impact of Chronic Total Occlusion Revascularization in Patients With Acute Myocardial Infarction Treated by Primary Percutaneous Coronary Intervention
2014
Overview
Coronary chronic total occlusion (CTO) carries a poor outcome in patients with acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (PCI). We sought to investigate the prognostic impact of a staged successful CTO-PCI in patients with AMI treated with primary PCI. Outcome analysis included consecutive patients treated by successful primary PCI with coexisting non–infarct-related artery CTO who survived after 1 week from AMI. A comparison between patients with successful CTO-PCI and patients with failed or nonattempted CTO-PCI was performed. The primary end points of the study were 1-year and 3-year cardiac survival. Of 1,911 patients who underwent successful primary PCI for AMI from 2003 to 2012, 169 (10%) had non–infarct-related artery CTO of a major branch. A staged CTO-PCI attempt was performed in 74 patients (44%) and was successful in 58 (success rate 78%). All patients with successful CTO-PCI received drug-eluting stents. In the successful CTO-PCI group, a complete coronary revascularization was achieved in 88% of the patients. The 1-year cardiac mortality rate was 1.7% in the successful CTO-PCI group and 12% in nonattempted or failed CTO-PCI group (p = 0.025). Successful CTO-PCI was an independent predictor of 3-year cardiac survival (hazard ratio 0.20, 95% confidence interval 0.05 to 0.92, p = 0.038). In conclusion, successful CTO-PCI in survivors after primary PCI is associated with improved long-term cardiac survival.
•Chronic total occlusion (CTO) carries a poor outcome in patients with acute myocardial infarction (AMI) treated by primary percutaneous coronary intervention (PCI).•Prognostic impact assessment of staged successful CTO-PCI in patients with AMI.•Successful CTO-PCI in patients with AMI is associated with improved long-term survival.
