background: percutaneous coronary intervention (pci) has become one of the most commonly performed cardiac procedures in clinical practice. due to improvement in outcomes, reduced acute complication rates, the need to reduce costs and the limited availability of hospital beds, elective pci with same-day discharge has become an interesting option. methods: single-center registry with a retrospective evaluation of all patients undergoing elective pci who were discharged on the same day, from january 2009 to march 2012. the rates of major adverse cardiac events (death, myocardial infarction, target-vessel revascularization and stroke), in addition to stent thrombosis, vascular complications and re-hospitalization between hospital discharge and the first 30 days of follow-up were determined. results: sixty-nine patients were evaluated with mean age of 64.5 ± 11.2 years, most of them were male (82%), and 28% were diabetics. all patients had stable coronary artery disease and type a or b1 lesions (36% and 36% respectively). radial access was the most commonly used approach (89%), with 5 f introducer sheaths in 56% and 6 f in the remaining patients. procedure success was obtained in 98.5%. no clinical events were observed at the 30-day follow-up. conclusions: our results demonstrated that same-day discharge was safe for patients with low clinical and angiographic risk undergoing elective pci with no procedure-related complications.
