2024年4月8日 · In this multinational, registry-based, randomized trial, we assigned patients with STEMI or very-high-risk non-STEMI (NSTEMI) and multivessel disease who were undergoing primary percutaneous...

2022年8月31日 · In patients with coronary artery disease who are being evaluated for percutaneous coronary intervention (PCI), procedures can be guided by fractional flow reserve (FFR) or intravascular...

2022年9月12日 · FFR is a guide wire-based procedure that accurately measures blood pressure and flow through an isolated coronary artery segment. A physician can do FFR through a standard diagnostic catheter during a coronary angiogram or cardiac catheterization.

2021年11月4日 · Patients with three-vessel coronary artery disease have been found to have better outcomes with coronary-artery bypass grafting (CABG) than with percutaneous coronary intervention (PCI), but...

2016年8月3日 · 近20年来，冠状动脉血流储备分数(fractional flow reserve，FFR)逐渐成为公认的有创病变功能学评价指标，以FFR指导的治疗策略被证实安全、经济，并能改善患者的预后 。我国和欧美等国家制定的指南均推荐应用FFR指导冠心病患者的血管重建。

6 天之前 · Key Points. Question Does the presence of diabetes affect the difference in outcomes after fractional flow reserve (FFR)–guided percutaneous coronary intervention (PCI) compared with coronary artery bypass grafting (CABG)?. Findings In this subgroup analysis of the FAME 3 randomized clinical trial, the risk of major adverse cardiac and cerebrovascular events (MACCE) at 3 years was higher ...

What is Fractional Flow Reserve (FFR)? FFR calculates the maximum flow down a vessel in the presence of stenosis compared to maximum flow in the hypothetical absence of the stenosis. A strong body of long-term clinical outcomes supports FFR to identify ischemia-producing lesions and shows improved outcomes over angio-guided procedures alone.

Post–percutaneous coronary intervention (PCI) fractional flow reserve (FFR) <0.90 is common and has been related to impaired patient outcome. The authors sought to evaluate if PCI optimization directed by intravascular ultrasound (IVUS) in patients with post-PCI FFR <0.90 could improve 1-year target vessel failure (TVF) rates.

The optimal post-PCI FFR cutoff value to predict 5-year TVF was determined based on the maximum log-rank statistic. Results: Post-PCI FFR measurements were successfully performed in 959 patients. Mean age was 64.0 ± 11.9 years, 72.5% of the patients were male and 33.6% presented with ST-segment elevation myocardial infarction. The left ...
