IMPORTANCE Outcomes in patients with diabetes after fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) using current-generation drug-eluting stents (DES) compared with coronary artery bypass grafting (CABG) are unknown. OBJECTIVES To investigate the relative treatment effect of PCI vs CABG according to diabetes status with respect to major adverse cardiac and cerebrovascular events (MACCE) at 3 years and to evaluate the impact of the SYNTAX score. DESIGN, SETTING, AND PARTICIPANTS This is a prespecified subgroup analysis of the FAME (Fractional Flow Reserve vs Angiography for Multivessel Evaluation) 3 trial, an investigator-initiated, randomized clinical trial conducted at 48 centers worldwide. The FAME 3 trial enrolled patients with 3-vessel coronary artery disease not involving the left main undergoing coronary revascularization between August 2014 and December 2019. Data analysis was conducted in August 2023. Clinical follow-up was performed at hospital discharge and at 1 month, 6 months, 1 year, 2 years, and 3 years after randomization. INTERVENTION Either FFR-guided PCI with current-generation DES or CABG. MAIN OUTCOMES AND MEASURES The primary end point was MACCE, defined as the composite of all-cause death, myocardial infarction, stroke, or repeat revascularization at 3 years. RESULTS Of 1500 total patients enrolled, mean (SD) patient age was 65.1 (8.4) years, and 265 patients (17.7%) were female. The FAME 3 trial included 428 patients with diabetes (28.5%). Patients with diabetes, especially those receiving insulin, had a higher risk of MACCE at 3 years compared with those without diabetes. Regarding relative treatment effect, the risk of MACCE was higher after FFR-guided PCI compared with CABG in both patients with diabetes (hazard ratio [HR], 1.44; 95% CI, 0.91-2.28; P = .12) and those without diabetes (HR, 1.50; 95% CI, 1.08-2.07; P = .02), with no significant interaction (P for interaction = .94). In patients with a low SYNTAX score (<23), there was no significant difference in MACCE between PCI and CABG, while in patients with an intermediate to high SYNTAX score (≥23), PCI had a higher risk of MACCE than CABG, regardless of diabetes status. CONCLUSIONS AND RELEVANCE In this subgroup analysis of the FAME 3 randomized clinical trial, the relative benefit of CABG compared with FFR-guided PCI was similar among patients with and without diabetes. © 2025 American Medical Association.

Background and Objectives: This study analyzed the frequency of factors influencing the course and outcomes of out-of-hospital cardiac arrest (OHCA) in Serbia and the prediction of pre-hospital outcomes and survival. Materials and Methods: Data were collected during the period from 1 October 2014, to 31 September 2023, according to the protocol of the EuReCa_One study (clinical trial ID number NCT02236819). Results: Overall 9303 OHCA events were registered with a median age of 71 (IQR 61–81) years and 59.7% of them being males. The annual OHCA incidence was 85.60 ± 20.73/100,000. Within all bystander-witnessed cases, bystander-initiated cardiopulmonary resuscitation in 15.3%. Within the resuscitation-initiated group, return-of-spontaneous circulation (ROSC) on scene (any ROSC) was present in 1037/4053 cases (25.6%) and ROSC on admission to the nearest hospital in 792/4053 cases (19.5%), while 201/4053 patients survived to hospital discharge (5.0%). Predictive potential on pre-hospital outcomes was shown by several factors. Also, of all patients having any ROSC, 89.2% were admitted to the hospital alive. The probability of any ROSC dropped below 50% after 17 min passed after the emergency call and 10 min after the EMS scene arrival. These time intervals were significantly associated with survival to hospital discharge (p < 0.001). Five-minute time intervals between both emergency calls and any ROSC and EMS scene arrival and any ROSC also had a significant predictive potential for survival to hospital discharge (p < 0.001, HR 1.573, 95% CI 1.303–1.899 and p = 0.017, HR 1.184, 95% CI 1.030–1.361, respectively). Conclusions: A 10-min time on scene to any ROSC is a crucial time-related factor for achieving any ROSC, and indirectly admission ROSC and survival to hospital discharge, and represents a golden time interval spent on scene in the management of OHCA patients. A similar effect has a time interval of 17 min from an emergency call. Further investigations should be focused on factors influencing these time intervals, especially time spent on scene. © 2024 by the authors.
