Fractional flow reserve-guided complete revascularization versus culprit-only percutaneous coronary intervention in patients with myocardial infarction: A meta-analysis of randomized controlled trials.

Introduction: The optimal revascularization strategy for patients with myocardial infarction (MI) and multivessel coronary artery disease (CAD) remains an area of research and debate. Fractional flow reserve (FFR)-guided complete revascularization (CR) by percutaneous coronary intervention (PCI) has emerged as an alternative to traditional culprit-only PCI.

Objective: To investigate the outcomes of FFR-guided CR versus culprit-only PCI in patients with MI and multivessel CAD.

Background: Subclinical leaflet thrombosis (SLT) is a common complication after transcatheter aortic valve replacement (TAVR). Multidimensional CT (MDCT) is the main imaging mortality for the diagnosis of SLT but it enhances the risk of contrast-induced nephropathy. Our study aimed to use an innovative wearable acoustic cardiography (ACG) device to diagnose SLT as an alternative option.

Background: In patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease, the optimal management strategy for non-culprit lesions is a subject of ongoing debate. There has been an increasing use of physiology-guidance to assess the extent of occlusion in non-culprit lesions, and hence the need for stenting. Fractional flow reserve (FFR) is commonly used as a technique.

Article Synopsis
  • The OCCUPI trial aimed to determine if optical coherence tomography (OCT) guidance during percutaneous coronary intervention (PCI) provides better clinical outcomes compared to traditional angiography guidance for complex heart lesions over a year.
  • Conducted across 20 hospitals in South Korea, the trial included 1,604 patients aged 19-85 and utilized randomization to assign participants to either OCT or angiography guidance during their PCI procedure.
  • The main outcome measured was the rate of major adverse cardiac events, but the effectiveness of OCT guidance in reducing these events compared to angiography guidance remains uncertain, as the study was designed to assess potential clinical benefits.

Article Synopsis
  • * A meta-analysis involving 14 studies and over 62,000 patients found that CR significantly reduces all-cause mortality, cardiovascular-related mortality, and risk of myocardial infarction in elderly patients undergoing percutaneous coronary intervention (PCI).
  • * Despite the benefits of CR, there were no significant differences in risks for stroke, major bleeding, stent thrombosis, or kidney injury, suggesting CR is a safe option for this population.
