Chronic total occlusion intervention of the non-infarct-related artery in acute myocardial infarction patients: the Korean multicenter chronic total occlusion registry

ABSTRACT


BACKGROUND - The Korean chronic total occlusion (CTO) registry was collected prospectively from 26 cardiovascular centers since May 2007. The aim of this study is to investigate the impact of a successful staged percutaneous coronary intervention (PCI) of CTO lesions in acute myocardial infarction (AMI) patients on clinical outcomes.


PATIENTS AND METHODS - Among 2813 patients who underwent a staged PCI because of CTO lesions, 422 (15%) patients underwent primary PCI because of AMI. Among 422 patients, successful staged CTO-PCI was performed in 76%. The clinical outcomes were compared between the successful CTO-PCI group (n=321) and the failed CTO-PCI group (n=101). To adjust for potential confounders, a propensity score matching (PSM) analysis was carried out using the logistic regression model.

RESULTS - After the PSM analysis, two propensity-matched groups (85 pairs, n=170) were generated and the baseline characteristics were balanced. The incidence of total death (P=0.029) and non-ST-segment elevation myocardial infarction (NSTEMI, P=0.043) at 1 year was higher in the failed CTO-PCI group. Multivariate regression showed that successful CTO-PCI was an independent predictor of preventing mortality (hazard ratio, 0.21, P=0.048). In the subgroup analysis, the Kaplan-Meier curve showed that successful CTO-PCI had a lower incidence of total death (log-rank=0.004) and cardiac death (log-rank=0.005) up to 1 year in NSTEMI patients. Cox-proportional analysis showed that successful CTO-PCI was beneficial in patients with NSTEMI, hypertension, and non-left-anterior descending artery lesion for preventing mortality.

CONCLUSION - In this study, a staged successful CTO-PCI in AMI patients was associated with improved 1-year survival in the Korean population.
