NCT06542653

Brief Summary

Coronary chronic total occlusions (CTOs) are considered to increase the risk of adverse clinical outcomes. The purpose of this study was to evaluate whether long-term clinical outcomes could be improved by successful percutaneous coronary intervention (PCI) over optimal medical therapy (OMT) in CTO patients.

Sampling MethodNon-Probability Sample
Study Population

Patients were referred for PCI based on CTO-related symptoms or evidence of viability, or corresponding ischemia in the area of the CTO artery. The enrolled patients were divided into 2 groups, i.e., CTO-PCI group (n=187) and CTO-OMT group (n=46). The strategy to perform PCI on CTO patients was dependent on some factors, including co-morbidity, technical challenges, operators' preference

You may qualify if:

  • patients with at least one coronary CTO lesion at our hospital in between January 2011 and December 2017

You may not qualify if:

  • (1) patients with ST-segment elevation myocardial infarction (STEMI)
  • (2)a history of coronary artery bypass grafting (CABG)
  • (3) cardiogenic shock
  • (4) malignant tumor. Patients were referred for PCI based on CTO-related symptoms or evidence of viability, or corresponding ischemia in the area of the CTO artery.
