- To describe the prognosis during 2 years after coronary artery bypass grafting (CABG) in relation to occurrence of and time since a previous acute myocardial infarction (AMI), data of all patients in western Sweden who underwent CABG without simultaneous valve surgery in the period June 1988-June 1991 were evaluated. In all, 2120 patients were included in the analyses. Of these, 1296 (61%) had a history of AMI and 127 (6%) had suffered an AMI within the last month before CABG. Mortality during the first 30 days after CABG was for patients with no previous AMI, previous AMI > 30 days prior to CABG, and previous AMI < or = 30 days prior to CABG 2.4%, 4.1%, and 5.5%, respectively (p < 0.05). The corresponding figures for the period between 30 days and 2 years after CABG were 3.6%, 4.4%, and 3.4% respectively (NS). In a multivariate analysis among patients with a previous AMI, a recent infarction (< or = 30 days prior to CABG) did not turn out as an independent predictor of death during 2 years of follow-up. A history of AMI was associated with increased mortality during the first 30 days but not thereafter, but recent AMI was not an independent predictor of total 2-year mortality.

Tidskriftsartikel (refereegranskat)abstract
- To derive and compare the need for hospitalization during 2 years prior to coronary artery bypass grafting (CABG) and 2 years after, all the patients from western Sweden in whom CABG without simultaneous valve surgery was performed between June 1988 and June 1991 were evaluated. Hospitalization prior to and after surgery was derived via questionnaires sent to the patients and via data from their hospital medical record forms. In all, 2099 patients were studied. The mean total number of days in hospital was 16 during the 2 years before and 24 including surgery and postoperative complications during the 2 years after the operation (p < 0.001). When the days for operation and postoperative complications were excluded, the mean number of days after operation was 7 (p < 0.001). Hospitalization due to myocardial infarction, angina pectoris, percutaneous transluminal coronary angioplasty and other investigations for heart disease were significantly reduced after CABG. On the other hand, hospitalization due to chest pain with causes other than ischemic heart disease, congestive heart failure, arrhythmias, and reoperation was more frequent during the 2 years after surgery. The total number of days in hospital was higher during the 2 years after CABG than during the 2 years before, despite the fact that hospitalization due to ischemic events was significantly reduced after the operation.
