Same day discharge versus overnight observation following chronic total occlusion percutaneous coronary intervention: Insights from the PROGRESS‐CTO registry

Abstract

AbstractBackgroundSame day discharge (SDD) following chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study.MethodsWe evaluated the clinical, angiographic, and procedural characteristics of patients discharged the same day versus those kept for overnight observation in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS‐CTO, NCT02061436).ResultsOf the 7181 patients who underwent CTO PCI, 943 (13%) had SDD. The SDD rate increased from 3% in 2015 to 21% in 2022. Patients with SDD were less likely to have a history of heart failure (21% vs. 26%, p = 0.005), chronic lung disease (10% vs. 15%, p = 0.001), or anemia (12% vs. 19%, p < 0.001). Technical success (87% vs. 88%, p = 0.289) was similar, but in‐hospital major adverse cardiovascular events (0.0% vs. 0.4%, p = 0.041) were lower in SDD. In multivariable logistic regression analysis, prior myocardial infarction odds ratio (OR): 0.71 (95% confidence interval [CI]: 0.59–0.87, p = 0.001), chronic lung disease OR: 0.64 (95% CI: 0.47–0.88, p = 0.006), and increasing procedure time OR: 0.93 (95% CI: 0.91–0.95, p < 0.001, per 10‐min increase) were associated with overnight observation, while radial‐only access OR: 2.45 (95% CI: 2.03–2.96, p < 0.001) had the strongest association with SDD. In the SDD, 2 (0.4%) of 514 patients were readmitted, due to retroperitoneal bleeding (n = 1) and ischemic stroke (n = 1).ConclusionThe overall frequency of SDD after CTO PCI was 13% and has been increasing over time. SDD is feasible in select patients following CTO PCI, and radial‐only access had the strongest association with SDD.
