Multi Vessel Coronary Artery Disease

Many patients with non-ST-segment elevation myocardial infarction (NSTEMI) have multivessel coronary artery disease (MVD), which is associated with poor clinical outcomes. However, there have been few studies regarding revascularization strategy in patients with NSTEMI and MVD. Therefore, we planned to perform prospective, open-label, randomized trial to evaluate the efficacy and safety of immediate complete revascularization (percutaneous coronary intervention \[PCI\] for both infarct-related artery \[IRA\] and non-IRA during index PCI) compared to staged PCI strategy of non-IRA (PCI for IRA followed by non-IRA PCI after several days). PCI procedure at non-IRA with diameter stenosis between 50 and 69% should be conducted with the aid of fractional flow reserve (FFR), and non-IRA with diameter stenosis ≥ 70% will be revascularized without FFR.

This study aimes to compare the clinical outcomes of drug-coated balloon-based percutaneous coronary intervention (DCB-based PCI) and drug-eluting stent-based percutaneous coronary intervention (DES-based PCI) in patients with multivessel coronary artery lesions measuring 2.25 mm to 4.0 mm in diameter through a prospective, multicenter, active-controlled, randomized, investigator-initiated clinical trial.

This study is a prospective, open-label, two-arm, randomized multicenter trial to identify whether immediate multi-vessel PCI would be better in clinical outcomes compared with culprit lesion-only PCI for AMI and multi-vessel disease with an advanced form of CS patients who require veno-arterial extracorporeal membrane oxygenator (VA-ECMO).

This study is a prospective, multicenter, open-label, observational study to investigate the impact of using drug-coated balloons (DCBs) in the treatment of coronary artery lesions in patients with multivessel coronary artery disease (MVD), as opposed to the default strategy of using only drug-eluting stents (DES). The investigators aim to assess changes in clinical practice towards a hybrid treatment strategy (DES and DCB) and its effects on clinical outcomes.

This prospective, multicenter, non-randomized, single arm, objective performance goal (OPG) study is designed to evaluate clinical outcomes after complete revascularization by PCI and imaging guidance (OCT) in patients with multivessel coronary artery disease including left anterior descending (LAD) presenting with stable angina, or documented silent ischemia, or non-ST segment elevation acute coronary syndrome (NSTE-ACS).
