From February 1996 to October 2001, 5,306 patients underwent multivessel off-pump coronary artery bypass, of whom 920 (17%) had unstable angina. In these 920 patients, ejection fractions ranged from 15% to 70%, 203 (22%) had an ejection fraction of 20%\u201335%, and 11 (1%) had an ejection fraction &lt; 20%. Triple-vessel disease was present in 625 patients. Preoperative intraaortic balloon pump support was used in 28 patients. Operative approaches included mid sternotomy (86%), lower partial sternotomy (9%), and left anterior thoracotomy (2%). The number of grafts ranged from 1 to 5 with a mean of 2.43 \u00b1 0.86, and 92.3% of patients received a left internal mammary artery graft. Twenty-two patients need intraoperative intraaortic balloon pumping. Ten patients (1%) suffered perioperative myocardial infarction. The mean hospital stay was 7.8 \u00b1 4.3 days. Hospital mortality was 2\/920 (0.22%). Intraaortic balloon pumping was helpful in these cases of unstable angina refractory to medical therapy. Off-pump coronary artery surgery was found to be safe and beneficial in these patients.<\/jats:p>","DOI":"10.1177\/021849230301100403","type":"journal-article","created":{"date-parts":[[2013,5,6]],"date-time":"2013-05-06T09:37:22Z","timestamp":1367833042000},"page":"285-288","source":"Crossref","is-referenced-by-count":2,"title":["Off-Pump
