Safety and predictors of same day discharge after elective percutaneous coronary intervention

Background Although same-day discharge (SDD) after elective uncomplicated percutaneous coronary intervention (PCI) be adopted worldwide, it remains poorly studied in our country. We aim to evaluate our initial experience with SDD after elective PCI, regarding its safety and predictors of success. Methods A hundred and sixty-one single-center consecutive patients, selected in a specialized outpatient clinic, were included for SDD. To identify the factors associated with SDD, single and multiple logistic regression models were adjusted. Results SDD was successfully performed in 114 patients (70.8%) and the remaining 47 patients remained hospitalized (45 with discharge in the following morning and 2 patients after 2 days). No patient with SDD presented major adverse cardiac events or major vascular complications at 30 days or at a median follow-up of 12 months. In the inpatient group, there was only one case of acute myocardial infarction due to a lateral branch occlusion and two patients with > 5 cm hematoma related to the access site. The SDD predictors were radial access route (OR = 5.92; 95%CI 1.73-20.21; p = 0.005), presence of type A/B1 lesions (OR = 14.09; 95%CI 1.70-116.49%; p = 0.01) and contrast volume (OR = 0.76; 95%CI 0.65-0.88; p < 0.001). Conclusions SDD was safe and could be successfully performed in most patients selected for elective PCI, and its predictors were the radial access, less complex coronary lesions and a and lower contrast volume.
