Evaluating the impact of PCI on patients with chronic coronary artery occlusion

Effect of PCI on Clinical Prognosis of Chronic Coronary Artery Occlusion

The First Affiliated Hospital with Nanjing Medical University · NCT06542653

This study is testing if a heart procedure called PCI can help people with chronic coronary artery blockages live longer and have fewer serious heart problems compared to those who only receive medication.

What this trial studies

This study assesses the long-term clinical outcomes of patients with chronic total occlusions (CTOs) who underwent percutaneous coronary intervention (PCI) compared to those receiving optimal medical therapy (OMT). Patients treated at the First Affiliated Hospital of Nanjing Medical University between January 2011 and December 2017 were divided into two groups based on their treatment. The primary focus is on major adverse cardiac cerebrovascular events (MACCE), including cardiac death and recurrent myocardial infarction, while secondary outcomes include all-cause mortality. The study aims to determine if PCI can provide better outcomes than OMT alone for CTO patients.

Who should consider this trial

Good fit: Ideal candidates are patients with at least one coronary CTO lesion who are being considered for PCI.

Not a fit: Patients with ST-segment elevation myocardial infarction (STEMI), a history of coronary artery bypass grafting (CABG), or other serious conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved long-term outcomes for patients with chronic total occlusions.

How similar studies have performed: Previous studies have indicated that PCI can improve outcomes in patients with CTOs, suggesting this approach has been successful in similar contexts.
