    • bjectives: To describe the characteristics and outcome of patients hospitalized for acute chest pain in relation to whether they were admitted to the coronary care unit (CCU) or not. Design: Prospective observational study with a follow-up of 2 years. Setting: Sahlgrenska University Hospital in Göteborg, Sweden. Subjects: All patients hospitalized due to acute chest pain during 6 months. Main outcome measures: Mortality, use of medical resources, complications and previous history. Results: In all 1.592 patients were admitted to hospital for chest pain, of whom 1.136 (71%) were not directly admitted to the CCU. These patients differed from those directly admitted to the CCU, being older, including more women, having a higher prevalence of known congestive heart failure and a lower degree of initial suspicion of acute myocardial infarction (AMI). Among all patients with confirmed AMI only 58% were directly admitted to CCU. Overall, the occurrence of complications and the use of medical resources were less frequent in the patients not admitted to the CCU. The mortality during the subsequent 2 years was 16.8% for patients not admitted to the CCU and 18.5% for patients admitted to the CCU. When adjusting for various factors at baseline, patients admitted to the CCU had a relative risk of death during 2 years of follow-up being 1.23 0.87–1.73 (P=0.24) as compared with those not admitted to the CCU. Conclusion: In a Swedish university hospital, more than two thirds of patients hospitalized for acute chest pain were not directly admitted to the CCU. They differed from those admitted to the CCU in several aspects. However, their unadjusted and adjusted mortality during the subsequent 2 years did not significantly differ from those admitted to CCU.

  • Long term prognosis after CABG in relation to preoperative left ventricular ejection fraction
  • 2000
  • Ingår i: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 72:2, s. 163-171
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: To evaluate the mortality rate, risk indicators for death, mode of death and symptoms of angina pectoris during 5 years after coronary artery by pass grafting (CABG) in relation to the preoperative left ventricular ejection fraction (LVEF). PATIENTS: All patients in western Sweden who underwent CABG without concomitant valve surgery and without previously performed CABG between June 1988 and June 1991. RESULTS: In all 1904 patients were included in the analysis, of whom 173 (9%) had a LVEF < 40%. Patients with LVEF > or = 40% had a 5-year mortality of 12.5%. LVEF < 40% was associated with an increased risk of death (RR 2.3; 95% cl 1.7-3.1). There was no significant interaction between age, sex or any other factor in terms of clinical history and LVEF. However, left main stenosis was a strong independent predictor of death among patients with LVEF < 40% but not in those with a higher LVEF. Patients with a low LVEF more frequently died a cardiac death and a death associated with myocardial infarction (AMI). Furthermore they more frequently died in association with congestive heart failure and ventricular fibrillation. Among survivors, symptoms of angina pectoris were similar regardless of the preoperative LVEF. CONCLUSION: Patients with a low preoperative LVEF have a more than two-fold increased risk of death during 5 years after CABG. Their increased risk of death includes cardiac death, death associated with AMI, congestive heart failure and ventricular fibrillation.

  • Predictors of death during 5 years after coronary artery bypass grafting
  • 1998
  • Ingår i: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 64:1, s. 15-23
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: To describe predictors of death during five years of follow-up after coronary artery bypass grafting (CABG). Methods: All patients who underwent CABG during a period of three years in Western Sweden were included in the analysis and were prospectively followed for five years. Mortality was related to preoperative and peroperative factors as well as findings at physical examination and medication 4–7 days after the operation. Results: In all 2121 patients underwent CABG without simultaneous valve surgery during the study period. The overall five-year mortality was 14.6%. The following appeared as independent predictors of death during five years but >30 days after CABG: Current smoking (relative risk ratio 2.43 [95% Ci 1.64–3.61]) degree of impairment of left ventricular function (1.51 [1.23–1.86]), a history of congestive heart failure (1.91 [1.35–2.70]), age (1.04 [1.02–1.06]) arrhythmia 4–7 days after CABG (1.89 [1.26–2.83]), intermittent claudication (1.73 [1.19–2.52]), a history of diabetes (1.71 [1.16–2.51]), time in respirator (1.43 [1.13–1.81]), a history of cerebrovascular disease (1.72 [1.13–2.64]), treatment with digitalis at day 4–7 (1.48 [1.07–2.05]), enzyme release (1.49 [1.03–2.16]). Conclusion: Among patients who underwent CABG 11 independent predictors for mortality were found including smoking habits at CABG, history of cardiovascular diseases, left ventricular dysfunction, age, post operative complications and medication after CABG.

  • Predictors of death during 5 years after hospital discharge among patients with a suspected acute coronary syndrome with particular emphasis on whether an infarction was developed
  • 1998
  • Ingår i: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 66:1, s. 73-80
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: To describe predictors of death after hospital discharge during 5 years of follow-up in a consecutive series of patients surviving hospitalization for symptoms and signs of a confirmed or suspected acute coronary syndrome. Patients and methods: All patients who between February 15, 1986 and November 9, 1987, were hospitalized at Sahlgrenska University Hospital in Göteborg, Sweden, and fulfilled the above given criteria. Results: In all, 1948 patients were included of whom 731 (38%) had a confirmed acute myocardial infarction (AMI). Independent risk indicators for death were: age (P=0.0001); male sex (P=0.005); a history of previous AMI (P=0.0001), diabetes mellitus (P=0.003) and smoking (P=0.0001); development of AMI during first 3 days in hospital (P=0.0001); in-hospital signs of congestive heart failure (P=0.0001); prescription of digitalis (P=0.001) and diuretics (P=0.02) at hospital discharge. A history of smoking interacted significantly (P=0.02) with the relationship between development of AMI and prognosis. Thus, the difference between patients who did and who did not develop an AMI was more pronounced among non-smokers than smokers. Other factors which interacted significantly with this relationship were a history of angina pectoris, and development of ventricular fibrillation and hypotension while in hospital. Conclusion: Among hospital survivors of a confirmed or suspected acute coronary syndrome predictors of death during 5 years were: age, male sex, history of AMI, diabetes mellitus and smoking, development of AMI and congestive heart failure while in hospital and prescription of digitalis and diuretics at hospital discharge. A history of smoking and angina pectoris as well as development of hypotension and ventricular fibrillation while in hospital interacted significantly with the relationship between development of AMI and prognosis.

  • Prognosis and risk indicators of death during a period of 10 years for women admitted to the emergency department with a suspected acute coronary syndrome
  • 2002
  • Ingår i: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 82:3, s. 259-268
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: To describe the 10-year prognosis and risk indicators of death in women admitted to the emergency department with acute chest pain or other symptoms raising a suspicion of acute myocardial infarction (AMI). Particular interest was paid to women of ≤75 years of age surviving 1 month after admission, who were judged to have suffered a possible or confirmed acute ischemic event with signs of either minor or no myocardial damage. Patients: All women admitted to the emergency department at Sahlgrenska University Hospital, Göteborg, during a period of 21 months, due to acute chest pain or other symptoms raising a suspicion of AMI. Methods: All the women were followed prospectively for 10 years. The subset described previously underwent a bicycle exercise tolerance test and metabolic screening 3 and 4 weeks, respectively, after admission to the emergency department. Results: In all, 5362 patients were admitted to the emergency department on 7157 occasions during the time of the survey and 2387 (45%) of them were women. Of these women, 61% were hospitalised and 39% were sent home directly. The overall 10-year mortality for women was 42.5% (55.5% among those hospitalised and 21.8% among those not hospitalised). Of the variables recorded at the emergency department, the following were independently associated with 10-year mortality: age, history of angina pectoris, history of hypertension, history of diabetes, history of congestive heart failure, pathological ECG on admission, degree of initial suspicion of AMI on admission, symptoms of congestive heart failure on admission and other non-specific symptoms on admission. The majority of these risk factors were more markedly associated with prognosis in women discharged directly from the emergency department than in those hospitalised. In the subset aged ≤75 years defined above (n=241), the following were independent predictors of death: a history of AMI and working capacity in a bicycle exercise tolerance test. Conclusion: Among women admitted to hospital due to chest pain or other symptoms raising a suspicion of AMI, 42.5% had died after 10 years. Major risk indicators of death were age, history of cardiovascular disease, pathological ECG on admission and symptoms of congestive heart failure on admission. Women presenting with an acute coronary syndrome but minimal myocardial damage, work capacity and a history of AMI predicted a poor outcome.

  • Ten-year mortality rate among patients in whom acute myocardial infarction was not confirmed in relation to clinical history and observations during hospital stay : experiences from the Göteborg Metoprolol Trial
  • 1994
  • Ingår i: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 44:3, s. 217-224
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The majority of patients hospitalized due to suspected acute myocardial infarction (AMI) will eventually not develop infarction. Information about the long-term prognosis in this patient population is limited. AIM: To describe the mortality during 10 years of follow-up in patients hospitalized due to an initially strong suspicion of AMI, but in whom the diagnosis of AMI could not be confirmed. PATIENTS: All patients participating in an early intervention trial with metoprolol in suspected AMI, but in whom the diagnosis was not confirmed. Patients were included during 1976-1981. RESULTS: In all 1395 patients were included in the study, of whom 586 did not fulfil the criteria for confirmed AMI. The overall mortality during 10 years of follow-up in this population was 26%. In a multivariate analysis considering age, sex, history of cardiovascular diseases, initial heart rate and various complications during the hospital stay, including congestive heart failure, severe ventricular arrhythmias, tachycardia, hypotension, high degree AV-block and severe chest pain, the following appeared as independent predictors of death: previous infarction (P < 0.001), age (P < 0.001), history of diabetes mellitus (P < 0.001) history of smoking (P < 0.05), history of hypertension (P < 0.05), male sex (P < 0.05), and the initial heart rate (P < 0.05). CONCLUSION: Among patients in whom AMI was not confirmed the major risk indicators for death during 10 years of follow-up were: a history of cardiovascular diseases and smoking, age, male sex and high heart rate on admission to hospital.

  • Use of medical resources complications and long-term outcome in patients hospitalized with acute chest pain. A comparison between a city university hospital and a county hospital
  • 2002
  • Ingår i: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 85:2-3, s. 229-238
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The primary aim was to test the hypothesis that there is a difference in long-term outcome after hospital discharge among patients hospitalized with acute chest pain in a university hospital and a county hospital. Secondary aims were to compare these two hospitals with regard to use of medical resources, occurrence of complications and risk indicators for death. Patients: All patients hospitalized at Sahlgrenska University Hospital in Göteborg (with a catchment population of 706 inhabitants/km2) and Uddevalla County Hospital (with a catchment population of 34 inhabitants/km2) due to symptoms of acute chest pain during a period of 6 months. Results: Complications, use of medical resources and mortality during the subsequent 2 years after discharge were compared among 1592 hospitalizations in a city hospital and 822 in a county hospital due to acute chest pain. Angina pectoris after the first event, congestive heart failure and various arrhythmias were more frequently reported in the county hospital. The use of medical resources differed. Thus, the use of betablockers, heparin, antiarrhythmics, diuretics and nipride was more frequent in the county hospital, whereas the use of nitrates, digitalis, coronary angiography, percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting (CABG) was more frequent in the city hospital. Despite these differences, the mortality 2 years after hospital discharge was similar (14.7% in the city hospital and 12.8% in the county hospital, P=0.26). Two factors, intravenous digitalis in hospital and a prescription of insulin at discharge, were significantly more associated with death in the county hospital compared with the city hospital. Conclusions: When comparing a city university hospital with a county hospital with regard to patients admitted with chest pain, major differences in terms of complications and use of medical resources were found. Thus, various complications were reported more frequently in the county hospital. The use of medical resources varied, some being used more frequently in the county hospital, whereas others were used more frequently in the university hospital. Despite these differences the mortality 2 years after hospital discharge was similar in the two cohorts.

  • Limitation of physical activity, dyspnea and chest pain before and two years after coronary artery bypass grafting in relation to sex
  • 1997
  • Ingår i: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 61:2, s. 123-133
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: To describe the limitation of physical activity and its causes, and symptoms of dyspnea and chest pain prior to and during two years after coronary artery bypass grafting (CABG) in relation to sex. Methods: All patients from western Sweden who underwent CABG between June 1988 and June 1991 were approached with a questionnaire prior to, three months and two years after CABG evaluating the issues raised above. Results: In all, 2121 patients were operated on, of which 81% were males. Physical activity was significantly improved and symptoms of chest pain and dyspnea were significantly reduced in both men and women after CABG. The improvement was significantly greater in males than in females even after adjustment for preoperative differences between the sexes. Conclusion: There was an improvement for both men and women in terms of limitations for physical activity and cardiovascular symptoms three months and two years after CABG as compared with prior to the operation. Female patients suffered from significantly more symptoms of chest pain and dyspnea and limitations in physical activity after CABG than men, also when adjustment was made for preoperative differences between the sexes.
