- AIM: To describe the epidemiology for out of hospital cardiac arrest of a non-cardiac aetiology. PATIENTS: All patients suffering from out of hospital cardiac arrest in whom resuscitation efforts were attempted in the community of Göteborg between 1981 and 2000. METHODS: Between October 1, 1980 and October 1, 2000, all consecutive cases of cardiac arrest in which the emergency medical service (EMS) system responded and attempted resuscitation were reported and followed up to discharge from hospital. RESULTS: In all, 5415 patients participated in the evaluation. Among them 1360 arrests (25%) were judged to be of a non-cardiac aetiology. Among these 24% were caused by a surgical cause or accident, 20% by obstructive pulmonary disease, 13% by drug abuse and the remaining 43% by 'another cause'. Of the patients with out of hospital cardiac arrest of a non-cardiac aetiology 4.0% survived to discharge from hospital as compared with 10.1% of the patients with a cardiac aetiology (P<0.0001). In the various subgroups survival was highest in those with drug abuse (6.8%) and lowest in those with 'another cause' (4.2%). Cerebral performance categories (CPC) score at hospital discharge tended to be worse among survivors from an arrest of non-cardiac than cardiac aetiology. Patients with a cardiac arrest of a non-cardiac aetiology differed from the remaining patients by being younger, including more women, less frequently having a witnessed arrest and less frequently being found in ventricular fibrillation/tachycardia. When simultaneously considering age, sex, witnessed status, presence of bystander cardiopulmonary resuscitation (CPR) and initial arrhythmia, the aetiology (non-cardiac vs. cardiac aetiology) was not an independent predictor of survival. CONCLUSION: Among patients with out of hospital cardiac arrest in whom resuscitation was attempted 25% were judged to be of a non-cardiac aetiology. These patients had a lower survival than patients with a cardiac arrest of cardiac aetiology. However, this was mainly explained by a lower occurrence of ventricular fibrillation and witnessed cardiac arrest.

- Aims: To describe the epidemiology, resuscitation factors and prognosis among a consecutive population of patients suffering from out-of-hospital cardiac arrest (OHCA) where pulseless electrical activity (PEA) was the first arrhythmia recorded on emergency medical services (EMS) arrival. Methods: Analysis of data collected prospectively on all patients regardless of age succumbing to OHCA during 1980–1997 in the community of Gothenburg where EMS initiated resuscitative measures. Results: 4662 patients with OHCA were attended by the EMS during the study period. Of these, 1069 (23%) were judged as having PEA as the first recorded arrhythmia; 158 (15%) of these were admitted alive to hospital and 26 (2.4%) were discharged alive. Survivors to discharge had a significantly larger share of bystander cardiopulmonary resuscitation (CPR) (28 vs. 8%, P=0.008), significantly higher levels of consciousness (8% awake vs. 0%, P<0.001) and higher median systolic blood pressure (145 vs. 106 mmHg, P<0.001) on arrival at hospital. No patient with unwitnessed cardiac arrest and PEA over 80 years old survived. Conclusion: Survival among patients suffering from OHCA and PEA is poor, especially among the elderly unwitnessed cases and those who do not receive bystander CPR. The latter seems to be of utmost importance among these patients.

- AIM: To describe patient characteristics, hospital investigations and interventions and early mortality among patients being hospitalized after out-of-hospital cardiac arrest in two hospitals. SETTING: Municipality of Göteborg, Sweden. PATIENTS: All patients suffering an out-of-hospital cardiac arrest who were successfully resuscitated and admitted to hospital between 1 October 1980 and 31 December 1996. All patients were resuscitated by the same Emergency Medical Service and admitted alive to one of the two city hospitals in Göteborg. RESULTS: Of 579 patients admitted to Sahlgrenska Hospital, 253 (44%) were discharged alive and of 459 patients admitted to Ostra Hospital, 152 (33%) were discharged alive (P < 0.001). More patients in Sahlgrenska Hospital were still receiving cardiopulmonary resuscitation (CPR) treatment (P = 0.03), but patients in Ostra had a lower systolic blood pressure and higher heart rate on admission. A larger percentage of patients admitted to Sahlgrenska Hospital underwent coronary angiography (P < 0.001), electrophysiological testing (P < 0.001), Holter recording (P < 0.001), echocardiography (P = 0.004), percutaneous transluminal coronary angioplasty (PTCA, P = 0.009), implantation of automatic implantable cardioverter defibrillator (AICD, P = 0.03) and exercise stress tests (P = 0.003). Inhabitants in the catchment area of Ostra Hospital had a less favourable socio-economic profile. CONCLUSION: Survival after out-of-hospital cardiac arrest may be affected by the course of hospital management. Other variables that might influence survival are socio-economic factors and cardiorespiratory status on admission to hospital. Further investigation is called for as more patients are being hospitalised alive after out-of-hospital cardiac arrest.

- The aim of our research was to study the long-term prognosis among patients discharged alive after an out-of-hospital cardiac arrest (OHCA) in comparison with patients discharged alive after acute myocardial infarction (AMI) without OHCA, and also to study the long-term influence of AMI in connection with OHCA. Our research was conducted in the municipality of Göteborg. We retrospectively studied patients discharged from hospital 1990-91 after an OHCA of cardiac aetiology and patients discharged after an AMI without prehospital cardiac arrest. During 1980-98, we studied all patients discharged alive after OHCA of cardiac aetiology, divided into groups of precipitating AMI and no AMI. The study includes 48 patients discharged alive after an OHCA 1990-91, 30 (62%) of whom had a simultaneous AMI and 1425 patients with an AMI without OHCA. Compared with AMI survivors, survivors of an OHCA of cardiac origin were younger but had more frequently a history of congestive heart failure. Their mortality rate during the subsequent 5 years was 46%, compared with 40% among survivors of an AMI (NS). The 5-year mortality rate among patients with an OHCA precipitated by an AMI was 40%. When correcting for differences at baseline, the adjusted risk ratio for death among patients with an OHCA of cardiac origin was 1.2 (95% CI 0.8-1.8) compared with patients with an uncomplicated AMI. During 1980-98, 215 patients were judged as having an OHCA precipitated by an AMI and 115 patients had an OHCA of cardiac aetiology but no simultaneous AMI. Five-year mortality was 54% and 50% respectively (NS). It is concluded that survivors of an OHCA of cardiac origin differed from survivors of an uncomplicated AMI in that they were younger and more frequently had a history of cardiovascular disease. Their 5-year mortality after discharge was similar to that of survivors of an AMI without a prehospital cardiac arrest, even after adjusting for differences at baseline.

- Abstract Background We studied time trends in long-term survival after out-of-hospital cardiac arrest (OHCA) for patient characteristics and described predictors for death after discharge. Because long-term prognosis among patients with coronary heart disease has improved in the last decades, we hypothesized that the prognosis after OHCA would improve with time. Methods We analyzed data that were prospectively collected from all patients discharged from the hospital after OHCA in the community of Göteborg, Sweden, from 1980 to 1998 and divided the data into 2 time periods, 1980 to 1991 and 1991 to1998, with an equal number of patients. Results A total of 430 patients were included in the survey. Age, sex proportions, cardiovascular comorbidity, resuscitation factors, and inhospital complications did not change with time. A diagnosis of a precipitating myocardial infarction was more common during period 1 (66% vs 54%). The prescription of aspirin (22% vs 52%), angiotensin-converting enzyme inhibitors (7% vs 29%), anticoagulants (13% vs 27%), and lipid-lowering agents (0% vs 6%) at discharge increased during period 2. Long-term survival did not improve with time; the 5-year mortality rates were 53% in period 1 and 52% in period 2. Independent predictors of an increased risk of death included age (risk ratio [RR] 1.06, 95% CI 1.05–1.08), history of myocardial infarction (RR 2.02, 95% CI 1.51–2.72), history of smoking (RR 1.77, 95% CI 1.29–2.44), and worse cerebral performance at discharge (RR 1.71, 95% CI 1.44–2.02). The prescription of β-blockers at discharge was independently predictive of decreased risk of death (RR 0.63, 95% CI 0.46–0.85). Conclusion The long-term survival rate after OHCA did not change. Baseline characteristics remained generally unchanged, but the drugs prescribed at discharge changed in several aspects. Age, a history of myocardial infarction, a history of smoking, cerebral performance category at discharge, and the prescription of β-blockers were independent predictors of outcome.

- Background. Extended dosing of the erythropoiesis-stimulating agent (ESA) darbepoetin alfa (DA) once biweekly or monthly reduces anaemia treatment burden. This observational study assessed outcomes and dosing patterns in patients with chronic kidney disease not on dialysis (CKD-NoD) commencing extended dosing of DA. Methods. Adult CKD-NoD patients starting extended dosing of DA in Europe or Australia in June 2006 or later were followed up until December 2012. Outcomes included haemoglobin (Hb) concentration, ESA dosing, mortality rates and receipt of dialysis and renal transplantation. Subgroup analyses were conducted for selected outcomes. Results. Of 6035 enrolled subjects, 5723 (94.8%) met analysis criteria; 1795 (29.7%) received dialysis and 238 (3.9%) underwent renal transplantation. Mean (standard deviation) Hb concentration at commencement of extended dosing was 11.0 (1.5) g/dL. Mean [95% confidence interval (CI)] Hb 12 months after commencement of extended dosing (primary outcome) was 11.6 g/dL (11.5, 11.6) overall and was similar across countries, with no differences between subjects previously treated with an ESA versus ESA-naive subjects, subjects with versus without prior renal transplant or diabetics versus non-diabetics. Weekly ESA dose gradually decreased following commencement of extended DA dosing and was similar across subgroups. The decrease in weekly DA dose was accompanied by an increase in the proportion of patients receiving iron therapy. Hb concentrations declined following changes in ESA labels and treatment guidelines. The mortality rate (95% CI) was 7.06 (6.68, 7.46) deaths per 100 years of follow-up. Subjects alive at study end had stable Hb concentrations in the preceding year, while those who died had lower and declining Hb concentrations in their last year. Conclusions. Long-term, extended dosing of DA maintained Hb concentrations in patients already treated with an ESA and corrected and maintained Hb in ESA-naive patients.

- Background: Knowledge about the prevalence of obstructive sleep apnea (OSA) in coronary artery disease (CAD) is insufficient. The aim of the current report was to evaluate the occurrence and predictors of OSA among revascularized patients with CAD within the framework of a randomized controlled trial (Randomized Intervention with CPAP in Coronary Artery Disease and Sleep Apnea [RICCADSA]), evaluating the impact of continuous positive airway pressure on cardiovascular outcomes in CAD patients with OSA. Material and Methods: All patients undergoing percutaneous coronary intervention or coronary artery bypass grafting between September 2005 and November 2010 (n = 1,291) were invited to participate. Anthropometrics and medical history were obtained, ambulatory sleep recording was performed, and all subjects completed the Epworth Sleepiness Scale (ESS) questionnaire. Results: In total, 662 patients participated in the sleep study. OSA, defined as an apnea–hypopnea index equal to or greater than 15/hour, was found among 422 (63.7%). The prevalence of hypertension was 55.9%; obesity (body mass index ≥ 30 kg/m2), 25.2%; diabetes mellitus, 22.1%; and current smoking, 18.9%. The patients with CAD who did not participate in the study demonstrated an almost similar anthropometric and clinical profile compared with the studied group. The majority (61.8%) of the patients with OSA were nonsleepy (ESS score < 10). Patients with OSA had a higher prevalence of obesity, hypertension, diabetes mellitus, and history of atrial fibrillation, whereas current smoking was more common in the non-OSA group. Age, male sex, body mass index, and ESS score, but not comorbidities, were independent predictors of OSA. Conclusions: The occurrence of unrecognized OSA in this revascularized CAD cohort was higher than previously reported. We suggest that OSA should be considered in the secondary prevention protocols in CAD.

- This paper reports, consistent with Utstein Style definitions, 13 years experience observing out-of-hospital cardiac arrest survivors' prognosis, longevity and functional status. We report for all patients, available outcome information for out-of-hospital cardiac arrest survivors in Göteborg Sweden between 1980 and 1993. Patients were followed for at least 1 year and some for over 14 years. From 1980 to 1993 Göteborg EMS treated 3754 out-of-hospital cardiac arrests. 9% (n = 324) were discharged from the hospital alive. Survivors' median age was 67 and 21% (n = 67) were women. Mortality rate was: 21% (n = 61) at 1 year; 56% (n = 78) by 5 years; and 82% (n = 32) by 10 years following the arrest. During the first 3 years, 16% (n = 46) experienced another cardiac arrest, 19% (n = 53) had an acute myocardial infraction and a total of 81% (n = 232) were rehospitalized for various conditions. 14% (n = 40) returned to previous employment, and 74% (n = 229) had retired before their arrest occurred. Cerebral performance categories (CPC) scores were: At hospital discharge N = 324; Data available for 320-1 = 53% (n = 171), 2 = 21% (n = 66), 3 = 24% (n = 77), 4 = 2% (n = 6). One year post arrest N = 263; Data available for 212-1 = 73% (n = 156), 2 = 9% (n = 18), 3 = 17% (n = 36), 4 = 1% (n = 2). Overall, 21% (n = 61) of cardiac arrest survivors died during the first year, and an additional 16% (n = 46) experienced another arrest. 73% of those patients who were still alive after 1 year returned to pre-arrest function.
