Since earlier days of percutaneous coronary intervention (PCI), there has been improvement in several aspects of PCI including use of transradial approach and third generation drug-eluting stents. Despite data showing its safety, same-day discharge (SDD) PCI has not been widely practiced in our institution and country. At present, there are no published studies from the Philippines showing the safety and outcome of SDD PCI.

The primary objective of this study is to determine and compare the safety and outcomes of SDD versus overnight observation ater PCI in The Medical City from 2018 to 2021.

This was a retrospective cohort study. The primary endpoint was to describe and compare the clinical profile of patients who underwent same-day versus overnight observation after PCI such as age, sex, comorbidities, indication for coronary angiogram, procedure time, total dye used, stent, and drug-eluting stent used. Incidence of major adverse cardiovascular event, mortality, readmission, and access site complications were also determined at 48 hours and 30 days after PCI.

Ninety-three patients were included in the analysis. Reasons for undergoing PCI were a positive noninvasive stress test (45%), stable angina (40%), coronary artery disease (26%), and heart failure (20%). More single-vessel (60%) than multivessel (40%) PCIs were performed. The most frequently affected coronary artery was the LAD (82%), followed by right coronary artery (32%) and left circumflex artery (30%). Compared with patients who stayed longer after PCI, the SDD group had lower mean (±SD) body mass index (25.10 ± 3.12 vs 28.55 ± 4.95 kg/m2), less due to a positive noninvasive test (26% vs 51%), more who underwent a single-vessel PCI (78% vs 54%), lower median amount of injected dye (130 vs 188 mL), shorter median procedural time (74 vs 101.5 minutes), and greater use of sirolimus-eluting stent (22% vs 3%). No adverse outcome of interest was noted in any patient up to 30 days after hospital discharge.

No adverse outcome was noted with SDD PCI. Larger, prospective, randomized comparative studies are needed to ascertain its safety before recommending SDD PCI routinely.
