Article Synopsis
- A 37-year-old male patient experienced a blockage in the left anterior descending (LAD) artery 45 days after an acute myocardial infarction (AMI) but refused immediate medical intervention.
- Two years later, a follow-up angiography revealed spontaneous recanalization of the LAD, showing unique structural changes through optical coherence tomography (OCT).
- The blockage was successfully treated with a drug-coated balloon, leading to excellent results for the patient.
Background: In patients underwent fractional flow reserve (FFR) assessment, a noteworthy proportion of adverse events occur in vessels in which FFR has not been measured. However, the effect of these non-target vessel-related events on the evaluation of FFR-related benefits remains unknown.
Methods And Results: In this retrospective study, vessels subjected to FFR measurement were grouped as FFR-based approach and non-compliance with FFR based on whether they received FFR-based treatment.
Aims: An improved left ventricular ejection fraction (HFiEF) was observed across heart failure (HF) patients with a reduced or mid-range ejection fraction (HFrEF or HFmrEF, respectively). We postulated that HFiEF patients are clinically distinct from non-HFiEF patients.
Methods And Results: A total of 447 patients hospitalized due to a clinical diagnosis of HF (LVEF <50% at baseline) were enrolled from September 2017 to September 2019.
Background: We aimed to investigate the association of lesion-specific epicardial adipose tissue (EAT) volume and density with the presence of myocardial ischemia.
Methods: We enrolled 45 patients (55 lesions) with known or suspected coronary artery disease who underwent coronary computed tomography angiography (CTA) followed by invasive fractional flow reserve (FFR) assessment within 30 days. EAT volume (index) and density in patient-, vessel- and lesion-level were measured on CTA images.
We searched PubMed, EMBASE, Cochrane Library, and Web of Science for studies using fractional flow reserve (FFR) to determine whether revascularization should be performed or deferred for patients with coronary stenosis and grey zone FFR. Meta-analysis was performed using the generic inverse variance method, and hazard ratios (HR) were synthesized with a random-effects model. Of 2766 records, 7 nonrandomized studies including 2683 patients were selected.

Between March 2013 and March 2017 in a high-volume center in China, 903 patients with 1210 lesions underwent coronary intervention with adjunctive FFR and were consecutively enrolled. The mean FFR was 0.

Methods: Of the 259 consecutive patients in Beijing Anzhen Hospital with ostial/midshaft LMCA lesions, 149 were treated with percutaneous coronary intervention (PCI) with DES and 110 were with CABG. The endpoints of the study were death, repeat revascularization, myocardial infarction (MI), stroke, the composite of cardiac death, and major adverse cardiac and cerebrovascular events (MACCE, the composite of cardiac death, MI, stroke or repeat revascularization).
