- The purpose of this study was to describe mortality during the 2-year-period after coronary artery bypass surgery (CABG) in relation to perioperative risk factors and urgency of operation. All the patients in western Sweden were included in whom CABG was performed between June 1988 and June 1991, without concomitant procedures or re-operations. The study was prospective in design. In all, 2000 patients were operated upon and 186 (9.3%) of the operations were acute. There was a significant relationship between the urgency of the operation and mortality. Early mortality was 2.4% in elective operations and 5.4-62.5% in urgent to emergency operations. The 30-day to 2-year mortality was 4.2%. The perioperative risk indicators independently associated with early mortality were neurologic complications, serum-aspartate aminotransferase (S-ASAT) more than 2.0 microkat/l, urgency of operation, the use of circulatory assist devices, re-operation and ventilator time more than 24 h. The risk indicators for mortality after 30 days were pneumothorax, longer intensive care unit (ICU) time, the use of inotropic drugs and neurologic complications. In conclusion, the multivariate analysis reveals the urgency of the operation as a predictor of early mortality after CABG, but no significant association with mortality was found after 30 days. When excluding death within 30 days, three additional independent predictors of mortality were identified.

- The aim of the study was to describe mortality during a period of two years after coronary artery bypass surgery (CABG) in relation to preoperative risk factors. Included were all the patients in western Sweden in whom CABG was performed between June 1988 and June 1991, without concomitant procedures or re-operations. The study was prospective in design. In all, 2000 patients with a median age of 64 years were operated upon. Early (within 30 days) mortality was 3.0% and late (30-day-2-year) mortality was 4.2%. Total two-year mortality was 7.1%. For patients undergoing coronary artery bypass grafting, the factors found to be independently predictive of early mortality were female sex, renal dysfunction (creatine clearance < 60ml/min), left main stenosis, number of diseased vessels, previous myocardial infarction, and functional class. We found that a history of congestive heart failure, a history of cerebrovascular disease, diabetes mellitus, renal dysfunction and intermittent claudication were independent risk factors for late mortality. In conclusion, with the exception of renal dysfunction, preoperative risk factors for death within 30 days after CABG differ from risk factors for death between 30 days and two years after CABG.

- OBJECTIVE: To describe the cause of death in the long term after coronary artery bypass grafting (CABG) with particular emphasis on cardiac death. PATIENTS AND SETTING: All the patients in western Sweden without simultaneous valve surgery and without previous CABG who underwent CABG in 1988-1991 in Goteborg, Sweden. DESIGN: Prospective, observational study for 10.6-13.6 years (i.e. until the end of 2001). Various factors contributing to death were described, with the emphasis on cardiac death. RESULTS: In all, 2000 patients were included in the survey. The all-cause mortality rate was 39%. Fifty-eight per cent of all deaths were judged as cardiac deaths. The most frequent cause of death was heart failure (65% among patients who died within 30 days after CABG and 36% among those who died >30 days after CABG). The second most common cause of death was myocardial infarction (56 and 29%, respectively), followed by cancer (0 and 24%, respectively), stroke (21 and 18%, respectively) and infection (8 and 11%, respectively). CONCLUSION: The factors most commonly contributing to death in the long term after CABG were, in order of frequency, heart failure, myocardial infarction, cancer, stroke and infection.

- 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.

- OBJECTIVE: To identify determinants of an inferior quality of life (QoL) 10 years after coronary artery bypass grafting (CABG). SETTING: Sahlgrenska University Hospital, Goteborg, Sweden. PARTICIPANTS: All patients from Western Sweden who underwent CABG between 1988 and 1991 without simultaneous valve surgery and no previous CABG. MAIN OUTCOME MEASURES: Questionnaires for evaluating QoL 10 years after the operation. Three different instruments were used: The Nottingham health profile (NHP), the psychological general wellbeing index (PGWI), and the Physical Activity Score (PAS). RESULTS: 2000 patients underwent CABG, of whom 633 died during 10 years of follow-up. Information on QoL at 10 years was available in 976 patients (71% of survivors). A history of diabetes and chronic obstructive pulmonary disease were the two independent predictors for an inferior QoL with all three instruments. Furthermore, there were three predictors of an inferior QoL with two of the instruments: high age, female sex and a history of hypertension. A number of factors predicted an inferior QoL with one of the instruments. These were the duration of angina pectoris and functional class prior to CABG, renal dysfunction, a history of cerebrovascular disease, obesity, height, duration of respirator treatment and requirement of inotropic drugs postoperatively. In addition, when introducing preoperative QoL into the model a low QoL before surgery was a strong independent predictor also of an inferior QoL 10 years after CABG. CONCLUSION: Variables independently predictive of an impaired QoL 10 years after CABG, irrespective of the instrument used, were an impaired QoL prior to surgery, chronic obstructive pulmonary disease and a history of diabetes. However, other factors reflecting gender, the previous history as well as postoperative complications were also associated with the QoL 10 years later in at least one of these instruments.

- AIM: To evaluate whether long-term treatment with a fixed low dose of warfarin in combination with aspirin improves the prognosis compared with aspirin treatment alone after an acute myocardial infarction (AMI). METHODS: Patients who were hospitalized for AMI were randomized to either 1.25mg of warfarin plus 75mg of aspirin (n=1659) daily or 75mg of aspirin alone (n=1641). The study was performed according to the PROBE (Prospective Open Treatment and Blinded End Point Evaluation) design and was conducted at 31 hospitals in Sweden. The median follow-up time was 5.0 years. In the aspirin+warfarin group, 30.2% were permanently withdrawn as opposed to 14.0% in the aspirin group (P<0.0001). Analyses were performed on an intention-to-treat basis. RESULTS: The combination of cardiovascular death, reinfarction or stroke was registered in 28.1% in the aspirin+warfarin group versus 28.8% in the aspirin group (NS). Cardiovascular deaths occurred in 14.2% in the aspirin+warfarin group vs 15.7% in the aspirin group (NS). Whereas no difference was found with regard to total mortality or reinfarction, those randomized to aspirin+warfarin had a reduced occurrence of stroke (4.7% vs 7.1%; P=0.004). The percentage of patients who suffered a serious bleed was 1.0% in the aspirin group vs 2.2% in the combination group (P=0.0006). CONCLUSION: A fixed low dose of warfarin added to aspirin in the long term after AMI did not reduce the combined risk of cardiovascular death, reinfarction or stroke. The results did, however, indicate that a fixed low dose of warfarin added to aspirin reduced the risk of stroke, but this was a secondary end point. The combination of aspirin and warfarin was associated with an increased risk of bleeding.

- OBJECTIVES: To describe the characteristics and outcome of patients with acute myocardial infarction (AMI) in a community, with particular emphasis on those who never reached a Coronary Care Unit (CCU) and those in whom the primary diagnosis was something other than a heart attack. METHODS: Patients hospitalised in the city of Goteborg, Sweden, and discharged (dead or alive) with a diagnosis of AMI. RESULTS: Among 1423 patient admissions the mean overall age was 75 years (81 years and 79 years in the two subsets). Among all patients, 33% had a history of heart failure and 20% had a history of cerebrovascular disease. The figures were even higher in the two subsets which were evaluated. In overall terms, an invasive strategy (coronary angiography) was used in 32% (in 5% and 9% in the two subsets respectively). The overall one-year and three-year mortality rate was 30% and 44% respectively. The three-year mortality rate among patients not admitted to a CCU was 65% and, among patients with no suspicion of a heart attack on admission, it was 68%. CONCLUSION: Even in the 21st century, patients with AMI who reach hospital alive run a high risk of death and nearly half are dead within the first three years. In overall terms, patients are characterised by high age and high co-morbidity. Among patients who do not reach a CCU and among patients with no suspicion of AMI on admission, approximately two thirds are dead within the subsequent three years.
