Importance: Chronic total occlusion percutaneous coronary intervention (CTO-PCI) is not usually offered because of skepticism about long-term clinical benefits. Objective: To assess the association of successful CTO-PCI with quality of life by analyzing the relevant domains of the Seattle Angina Questionnaire (SAQ). Data Sources: PubMed, EMBASE, Web of Science, Google Scholar, and Cochrane databases were searched to identify randomized trials and observational studies specifically addressing quality of life domains of SAQ from January 2010 to June 2022. Study Selection: Studies included reporting SAQ metrics such as angina frequency, physical limitation, and quality of life, before and after CTO-PCI. Data Extraction and Synthesis: The present study was performed according to the Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses statements, in which fixed-effect or random-effect models with generic inverse-variance weighting depending on statistical homogeneity were applied. Data were extracted by 3 independent reviewers. Outcomes and Measures: The primary outcome was angina frequency; physical limitation and quality of life were assessed as secondary outcomes. Results: Seven prospective randomized or observational studies (2500 patients) were included, with a mean (SD) participant age of 61.2 (2.1) years. CTO-PCI was associated with significantly improved quality-of-life metrics during a mean (SD) follow-up of 14.8 (16.3) months. In patients with successful procedures, angina episodes became less frequent (mean [SD] difference for SAQ angina frequency of 12.9 [3.1] survey points [95% CI, 7.1-19.8 survey points]; standardized mean difference was 0.54 [95% CI, 0.21-0.92]; P =.002; I2 = 86.4%) and they experienced less physical activity limitation (mean [SD] difference for SAQ physical limitation of 9.7 [6.2] survey points [95% CI, 3.5-16.2 survey points]; standardized mean difference was 0.42 [95% CI, 0.24-0.55]; P <.001; I2 = 20.9%), and greater quality-of-life domain (mean [SD] difference for SAQ quality of life of 14.9 [3.5] survey points [95% CI, 7.7-22.5 survey points]; standardized mean difference was 0.41 [95% CI, 0.25-0.61]; P <.001; I2 = 58.8%) compared with patients with optimal medical therapy or failed procedure. Furthermore, follow-up duration (point estimate, 0.03; 95% CI, 0.01-0.04; P =.01) was associated with a significant decrease in angina frequency in meta-regression analysis. Conclusions and Relevance: In this systematic review and meta-analysis examining quality of life following CTO-PCI, successful procedures were associated with improved quality-of-life parameters compared with patients on optimal medical therapy or after failed CTO-PCI. These findings suggest support for using PCI to treat CTOs in symptomatic patients unresponsive to medical treatment. © 2023 American Medical Association. All rights reserved.

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.
