- Aim To describe the relative impact on survival of the delay from estimated time of collapse to call for an ambulance among patients who suffer from a bystander witnessed out of hospital cardiac arrest of a cardiac aetiology. Methods A majority of all ambulance organizations in Sweden (covering 85% of Sweden inhabitants) participate in a National survey of out of hospital cardiac arrest. Results In all there were 9340 patients with a bystander witnessed cardiac arrest of a cardiac aetiology in whom cardiopulmonary resuscitation (CPR) was attempted participating in this survey. Survival at one month among patients with a delay between estimated time of collapse and call for ambulance of less than or equal to4 min (median) was 6.9% versus 2.8% among patients with a median of >4 min (P<0.0001). When adjusting for age, sex, initial rhythm, estimated interval between collapse and start of CPR, place of arrest and the interval between call for ambulance and arrival of the rescue team, the odds ratio for survival was 0.70 (0.95% Cl. 0.58-0.84) per unit increase of the natural logarithm of delay in minutes between collapse and call. Conclusion Among patients with a bystander witnessed out of hospital cardiac arrest of a cardiac aetiology increased delay from estimated time of collapse to call for an ambulance decreased the chance of survival.

- Aims: Individuals with low socioeconomic status (SES) face widespread prejudice in society. Whether SES disparities exist in treatment and survival following in-hospital cardiac arrest (IHCA) is unclear. The aim of the current retrospective registry study was to examine SES disparities in IHCA treatment and survival, assessing SES at the patient level, and adjusting for major demographic, clinical, and contextual factors.Methods and results: In total, 24 217 IHCAs from the Swedish Register of Cardiopulmonary Resuscitation were analysed. Education and income constituted SES proxies. Controlling for age, gender, ethnicity, comorbidity, heart rhythm, aetiology, hospital, and year, primary analyses showed that high (vs. low) SES patients were significantly less likely to receive delayed cardiopulmonary resuscitation (CPR) (highly educated: OR = 0.89, and high income: OR = 0.98). Furthermore, patients with high SES were significantly more likely to survive CPR (high income: OR = 1.02), to survive to hospital discharge with good neurological outcome (highly educated: OR = 1.27; high income: OR = 1.06), and to survive to 30 days (highly educated: OR = 1.21; and high income: OR = 1.05). Secondary analyses showed that patients with high SES were also significantly more likely to receive prophylactic heart rhythm monitoring (highly educated: OR = 1.16; high income: OR = 1.02), and this seems to partially explain the observed SES differences in CPR delay.Conclusion: There are clear SES differences in IHCA treatment and survival, even when controlling for major sociodemographic, clinical, and contextual factors. This suggests that patients with low SES could be subject to discrimination when suffering IHCA.

- AIM: To describe the occurrence of death, development of acute myocardial infarction and need for hospitalization among patients on the waiting list for coronary artery by pass grafting and percutaneous transluminal coronary angioplasty. PATIENTS AND METHODS: All the patients on the waiting list for possible coronary revascularization in September 1990 in western Sweden. RESULTS: Of 718 patients waiting for either coronary artery bypass grafting or percutaneous transluminal coronary angioplasty, 15 (2.1%) died between the actual week in September 1990 and prior to revascularization and 12 (1.7%) developed a non-fatal acute myocardial infarction during the same period. All 15 patients who died before undergoing revascularization died a cardiac death. Death and/or the development of an acute myocardial infarction was significantly more frequent among the elderly, among patients with a low ejection fraction and among patients with a history of diabetes mellitus. In all, 29% required hospitalization prior to the procedure. The most common reason was symptoms of angina pectoris requiring hospitalization in 23% of the patients. CONCLUSION: Among patients on the waiting list before either coronary artery bypass grafting or percutaneous transluminal coronary angioplasty, 15 (2.1%) died prior to the procedure and 1.7% developed a non-fatal acute myocardial infarction. The risk of either death or developing an acute myocardial infarction was highest among patients in the older age groups, among patients with a history of diabetes mellitus and among patients with a lower ejection fraction.

- The effect of high thoracic epidural anaesthesia with intermittent epidural bolus injections of bupivacaine (2.5 or 5 mg ml-1) was studied in 28 patients with unstable angina pectoris. The majority of the patients had a history of previous acute myocardial infarction(s) and/or angina pectoris and severe coronary artery disease. All patients were treated wth nitroglycerin infusion for gt;24 h and were included in the study if they had chest pain, not caused by acute myocardial infarction, at bed rest or recurrent anginal pain at rest < 2 days after infarction. 4.4 ± 0.3 ml of bupivacaine induced a blockade of the upper seven sympathetic segments ( Th1-7) for 98 ± 9min. Heart rate decreased significantly from 70 ± 3 to 64 ± 3 beats min-1 while blood pressure was unaffected by thoracic epidural anaesthesia. In 27 patients (96%) the anaesthesia induced complete analgesia. Nitroglycerin infusion was discontinued definitely within 3 h in 26 patients (93%) and pain was thereafter controlled by means of thoracic epidural anaesthesia as the sole treatment in 23 patients (82%) and as the major treatment in 25 patients (89%). Twenty-one patients (75%) were fully mobilized and stabilized. Treatment with thoracic epidural anaesthesia lasted for 6.0 ± 1.1 days. The number of daily epidural injections decreased significantly with time from 2.7 ±0.3 the first day to 0.9 ± 0.3 the fourth day (P>0.01, n = 19). Two patients developed acute myocardial infarction during the anaesthesia treatment period, and one of these patients died. Exercise stress testing was performed on eight patients three to five days after the start of thoracic epidural anaesthesia. At a comparable workload, ST-segment depression was significantly (P>0.05) less pronounced during anaesthesia ( − 0.6 ± 0.1 mm) compared with control ( − 1.3 ± 0.2mm). The respective heart rate values were 95 ± 7 and 107 ± 7 beats min -1 (P > 0.05), while systolic or diastolic blood pressure did not differ between the two conditions. We conclude that blockade of cardiac sympathetic afferents and efferents by means of thoracic epidural anaesthesia can effectively treat pain and stabilize patients with unstable angina pectoris refractory to medical treatment. Furthermore, thoracic epidural anaesthesia attenuates stress-induced myocardial ischaemia; thus, it may be an efficient supplementary treatment for the control of pain and for stabilizing patients with unstable angina pectoris during diagnostic procedures and prior to coronary surgery or angioplasty.

- Objective To describe mortality and morbidity during a period of 2 years after coronary artery bypass grafting in relation to gender. Design Prospective follow-up study. Setting Two regional cardiothoracic centres which performed all the coronary artery bypass operations in western Sweden at the time. Sub|ects A total of 2129 (1727 (81%) men and 402 (19%) women) consecutive patients undergoing coronary artery bypass surgery between June 1988 and June 1991 without concomitant procedures. Results Females were older and more frequently had a history of hypertension, diabetes mellitus, congestive heart failure, renal dysfunction and obesity. In a multivariate analysis, taking account of age, history of cardiovascular diseases and renal dysfunction, female sex appeared as a significant independent predictor of mortality during the 30 days after coronary artery bypass grafting (/><0-05), but not thereafter. Various postoperative complications including neurological deficit, hydro- and pneumo-thorax, perioperative myocardial damage and the need for assist devices and prolonged reperfusion were more common in females than males. Conclusion Females run an increased risk of early death and the development of postoperative complications after coronary artery bypass surgery as compared with males. Late mortality does not appear to be influenced by gender and the long-term benefit of the coronary artery bypass graft operation is similar in men and women.

- Congestive heart failure is one of the major symptoms accompanying acute myocardial infarction (AMI). The study aimed to describe the occurrence, characteristics and prognosis of congestive heart failure in AMI and to compare post-MI patients with and without congestive heart failure. The methods used included baseline characteristics, initial symptoms, electrocardiogram (ECG), mortality during hospitalization and one year follow-up in consecutive patients with AMI admitted to Sahlgrenska Hospital, Göteborg, Sweden. Congestive heart failure was observed in 51% of the cases. Patients with congestive heart failure were older, more frequently had a history of previous cardiovascular disease, and, less frequently had chest pain on admission to hospital. They had a higher occurrence of life-threatening ventricular arrhythmias during initial hospitalization, and their mortality during one year follow-up was 39% as compared to 17% in patients without congestive heart failure (P<0.001). This difference remained significant when correcting for differences at baseline. Patients with severe congestive heart failure had a one year mortality of 47% vs 31% in patients with moderate congestive heart failure (P<0.01). Signs and symptoms of congestive heart failure occur in every second patient admitted to hospital due to AMI, and indicate a bad prognosis, which is directly related to the severity of congestive heart failure.

- BACKGROUND: A large number of patients who call for an ambulance because of acute chest pain have an acute ischaemic event, but some do not. AIM. To relate the ambulance despatcher's estimated severity of pain and presence of associated symptoms, in patients who call for an ambulance because of acute chest pain, to whether they develop acute myocardial infarction (AMI) and to the risk of early death. PATIENTS: All those with acute chest pain who contacted the despatch centre in Göteborg over a 2-month period. RESULTS: In all, 503 patients fulfilled the inclusion criteria. Patients judged as having severe chest pain (68%) developed AMI during the first 3 days in hospital on 26% of occasions as compared with 13% among patients judged as having only vague chest pain (P = 0.0004). The difference was less marked among the elderly and women. The presence of any of the following associated symptoms, dyspnoea, nausea, vertigo, cold sweat or syncope, tended to be associated with a higher infarction rate (24%) than if none of these symptoms was present (17%, P = 0.06). Mortality during the pre-hospital and the hospital phase was not associated with the estimated severity of pain or the presence of associated symptoms. CONCLUSIONS: The despatcher's estimation of the severity of pain and the presence of associated symptoms appears to be associated with the development of AMI but not with early mortality.
