Resultados hospitalares da interven？？o coronária percutanea Ad Hoc vs. eletiva

background: ad hoc percutaneous coronary intervention (pci) has proven to be safe in certain subsets of patients and the number of procedures has grown steadily over the years. in face of the scarcity of literature publications, we performed a comparative analysis of in-hospital outcomes of ad hoc and elective pcis. methods: from 2006 to 2010, 4,957 consecutive patients were submitted to pci and were included in the hospital bandeirantes registry. patients undergoing primary or rescue pci were excluded and of the remaining 4,048 patients, 1,510 (37.3%) were submitted to ad hoc pci and 2,538 to elective pci. results: the ad hoc pci group was younger, had a lower prevalence of comorbidities and a greater number of patients were treated in the presence of acute coronary syndrome. they exhibited less complex coronary lesions, used larger diameter stents and had more transient flow impairments during pci. procedure success was similar between groups (97% vs. 96.8%; p = 0.70) as well as the occurrence of death (0.5% vs. 0.3%; p = 0.19), myocardial infarction (1.3% vs. 1.8%; p = 0.17), emergency coronary artery bypass graft surgery (0.4% vs. 0.2%; p = 0.36), stroke (0.1% vs. 0; p = 0.71) and major vascular complications (0.3% vs. 0.4%; p = 0.64). conclusions: ad hoc pci is performed in lower risk patients and the outcomes demonstrate it is a safe procedure for most of the selected patients.
