Stroke after coronary artery bypass surgery with and without cardiopulmonary bypass

Background: stroke is a devastating complication of coronary artery bypass grafting (cabg). this study was carried out with the aim that the development of off pump coronary artery surgery decreases the incidence/adverse outcome due to extra corporeal circulation.methods: the data utilized in this study was extracted from a randomized controlled trial that was conducted from january 2006 to march 2007 at punjab institute of cardiology. one hundred patients were included in 'on pump' group-a,and 100 patients in 'off pump' group-b.results: the mean age of the patients in group-a was 53.51 ± 9.96 years and in group-b it was 51.59 ± 10.30 years. renal failure occurred in 21% patients of group-a as compared to 10% of group-b while acute myocardial infarction occurred in significantly higher number of patients in group-b (11%) as compared to group-a (2%). off pump was associated with significant decrease in rate of stroke 1.5% as compared to on pump 3.5%. similarly there was decreased in the risk of deaths after stroke 0% as compared to on pump 1.5% mortality after stroke. in group a 6 (3.5%) patients developed stroke where as in group-b 2 (1.5%) patients developed stroke out of these 6 patients there were 2 mortalities after stroke in group-a while in group-b there was no mortality after stroke within 30 days postoperatively.conclusion: off pump cabg is associated with significantly decreased rate of stroke in comparison with the on-pump cabg.
