- Background: Previous metoprolol studies in myocardial infarction patients were performed with immediate-release (IR) metoprolol. This study aims to evaluate if extended-release metoprolol CR/XL once daily gives a similar β-blockade over 24 h compared to multiple dosing of metoprolol IR. Methods: After 2 days of routine metoprolol treatment, 27 patients with suspected acute myocardial infarction were randomized to open-label treatment with metoprolol IR (50 mg four times daily or 100 mg twice daily) or metoprolol CR/XL 200 mg once daily for 3 days. Results: Metoprolol CR/XL 200 mg once daily gave more pronounced suppression of peak heart rate, with lower peak and less variation in peak to trough plasma levels. There were no differences in AUC between the CR/XL and IR formulations, although the trough plasma metoprolol levels were comparable for metoprolol CR/XL 200 mg once daily and metoprolol IR 50 mg four times daily, but lower for metoprolol IR 100 mg twice daily. Both treatments were well tolerated. Conclusions: Metoprolol CR/XL 200 mg once daily showed lower peak and less variation in peak to trough plasma levels compared to multiple dosing of metoprolol IR with the same AUC. This was accompanied by a more uniform β-blockade over time, which was reflected by heart rate, and a more pronounced suppression of peak heart rate with similar tolerability. This suggests metoprolol CR/XL may be used as an alternative to metoprolol IR in patients with myocardial infarction.

- OBJECTIVES: Survival after out-of-hospital cardiac arrest (OHCA) varies between communities, due in part to variation in the methods of measurement. The Utstein template was disseminated to standardize comparisons of risk factors, quality of care, and outcomes in patients with OHCA. We sought to assess whether OHCA registries are able to collate common data using the Utstein template. A subsequent study will assess whether the Utstein factors explain differences in survival between emergency medical services (EMS) systems. STUDY DESIGN: Retrospective study. SETTING: This retrospective analysis of prospective cohorts included adults treated for OHCA, regardless of the etiology of arrest. Data describing the baseline characteristics of patients, and the process and outcome of their care were grouped by EMS system, de-identified, and then collated. Included were core Utstein variables and timed event data from each participating registry. This study was classified as exempt from human subjects' research by a research ethics committee. MEASUREMENTS AND MAIN RESULTS: Thirteen registries with 265 first-responding EMS agencies in 13 countries contributed data describing 125,840 cases of OHCA. Variation in inclusion criteria, definition, coding, and process of care variables were observed. Contributing registries collected 61.9% of recommended core variables and 42.9% of timed event variables. Among core variables, the proportion of missingness was mean 1.9±2.2%. The proportion of unknown was mean 4.8±6.4%. Among time variables, missingness was mean 9.0±6.3%. CONCLUSIONS: International differences in measurement of care after OHCA persist. Greater consistency would facilitate improved resuscitation care and comparison within and between communities.

- Objectives. In a review based on estimations and assumptions, to report the estimated number of survivors after out-of-hospital cardiac arrest (OHCA) in whom cardiopulmonary resuscitation (CPR) was started and to speculate about possible future improvements in Sweden.Design. An observational study. Setting All ambulance organisations in Sweden. Subjects Patients included in the Swedish Cardiac Arrest Registry who suffered an OHCA between January 1, 2008 and December 31, 2010. Approximately 80% of OHCA cases in Sweden in which CPR was started are included. Interventions NoneResults. In 11005 patients, the 1-month survival rate was 9.4%. There are approximately 5000 OHCA cases annually in which CPR is started and 30-day survival is achieved in up to 500 patients yearly (6 per 100000 inhabitants). Based on findings on survival in relation to the time to calling for the Emergency Medical Service (EMS) and the start of CPR and defibrillation, it was estimated that, if the delay from collapse to (i) calling EMS, (ii) the start of CPR, and (iii) the time to defibrillation were reduced to <2min, <2min, and <8min, respectively, 300400 additional lives could be saved.Conclusion. Based on findings relating to the delay to calling for the EMS and the start of CPR and defibrillation, we speculate that 300400 additional OHCA patients yearly (4 per 100000 inhabitants) could be saved in Sweden.

Tidskriftsartikel (refereegranskat)abstract
- Although low-dose acetylsalicylic acid (ASA) is recommended for prevention of cardiovascular events in at-risk patients, its long-term use can be associated with the risk of peptic ulcer and upper gastrointestinal (GI) symptoms that may impact treatment compliance. This prespecified secondary analysis of the OBERON study (NCT00441727) determined the efficacy of esomeprazole for prevention/resolution of low-dose ASA-associated upper GI symptoms. A post hoc analysis of predictors of symptom prevention/resolution was also conducted. Helicobacter pylori-negative patients taking low-dose ASA (75-325 mg) for cardiovascular protection who had ≥1 upper GI risk factor were eligible. The patients were randomized to once-daily esomeprazole 40 mg, 20 mg, or placebo, for 26 weeks; 2303 patients (mean age 67.6 years; 36% aged >70 years) were evaluable for upper GI symptoms. The proportion of patients with dyspeptic or reflux symptoms (self-reported Reflux Disease Questionnaire) was significantly lower (P < 0.0001) in those treated with esomeprazole versus in those treated with placebo. Treatment with esomeprazole (P < 0.0001), age >70 years (P < 0.01), and the absence of upper GI symptoms at baseline (P < 0.0001) were all factors associated with prevention/resolution of upper GI symptoms. Together, these analyses demonstrate that esomeprazole is effective in preventing and resolving patient-reported upper GI symptoms in low-dose ASA users at increased GI risk.

- Peripartumkardiomyopati är en sällsynt form av hjärtsvikt. Diagnostiska kriterier är nytillkommen hjärtsvikt från sen graviditet och upp till fem månader efter förlossning, avsaknad av annan förklaring till hjärtsvikt och nedsatt systolisk vänsterkammarfunktion Orsaken till tillståndet tros vara omvandling av prolaktin till en kardiotoxisk variant. Terapin är den etablerade, men ACE-hämmare och ARB får inte ges till ammande mödrar. Hjärttransplantation har tillgripits. Maligna hjärtarytmier har krävt behandling med implanterbar defibrillator och pacemaker. Hämning av produktionen av prolaktin med bromokriptin har gett goda resultat i en liten studie. Resultaten har inte bekräftats.

- AIM: The aim of this study is to describe the outcome changes after out-of-hospital cardiac arrest (OHCA) in Gothenburg, Sweden, after introduction of mechanical chest compression (MCC). METHODS: Following introduction of MCC, 1183 OHCA patients were treated from November 1, 2007, to December 31, 2011 (period 2). They were compared with 1218 OHCA patients before MCC was introduced from January 1, 1998, to May 30, 2003 (period 1). Patients in period 2 were evaluated for survival in relation to MCC use. RESULTS: The percentage of patients admitted to hospital alive increased from 25.4% to 31.9% (P < .0001). Survival to 1 month increased from 7.1% to 10.7% (P = .002) from period 1 to period 2. The proportion of ventricular fibrillation/ventricular tachycardia decreased in period 2 (P = .002). However, bystander cardiopulmonary resuscitation (P < .0001), crew-witnessed cases (P = .04), percutaneous coronary intervention (P < .0001), therapeutic hypothermia (P < .0001), and implantable cardioverter-defibrillator use (P = .01) increased, as did time from call to emergency medicine service arrival (P < .0001) and to defibrillation (P = .006). In period 2, 60% of OHCA patients were treated with MCC. The percentages admitted alive to hospital (MCC vs no MCC) were 28.6% and 36.1% (P = .008). Corresponding figures for survival to 1 month were 5.6% and 17.6% (P < .0001). In the MCC group, we found increase in the delay from collapse to defibrillation (P < .0001), greater use of adrenaline (P < .0001), and fewer crew-witnessed cases (P < .0001). CONCLUSION: Survival to 1 month after implementation of MCC was higher than before introduction. However, patients receiving MCC had low survival. Although case selection might play a role, results do not support a widespread use of MCC after OHCA.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To identify levels of kinesiophobia during the first 4 months after an acute episode of coronary artery disease (CAD), while controlling for gender, anxiety, depression, and personality traits. Methods: In all, 106 patients with CAD (25 women), mean age 63.1 11.5 years, were included in the study at the cardiac intensive care unit, Sahlgrenska University Hospital, Sweden. The patients completed questionnaires at 3 time points: in the cardiac intensive care unit (baseline), 2 weeks, and 4 months after baseline. The primary outcome measure was kinesiophobia. Secondary outcome measures were gender, anxiety, depression, harm avoidance, and positive and negative affect. A linear mixed model procedure was used to compare kinesiophobia across time points and gender. Secondary outcome measures were used as covariates. Results: Kinesiophobia decreased over time (P = .005) and there was a significant effect of gender (P = .045; higher values for women). The presence of a high level of kinesiophobia was 25.4% at baseline, 19% after 2 weeks, and 21.1% after 4 months. Inclusion of the covariates showed that positive and negative affect and harm avoidance increased model fit. The effects of time and gender remained significant. Conclusions: This study highlights that kinesiophobia decreased over time after an acute CAD episode. Nonetheless, a substantial part of the patients were identified with a high level of kinesiophobia across time, which emphasizes the need for screening and the design of a treatment intervention.

Tidskriftsartikel (refereegranskat)abstract
- AIM: To evaluate changes in characteristics and survival over time in out-of-hospital cardiac arrest (OHCA) due to drowning and describe factors of importance for survival. METHOD: Retrospectively reported and treated drowning cases reported to the Swedish OHCA registry between 1990 and 2012, n=529. The data were clustered into three seven-year intervals for comparisons of changes over time. RESULTS: There were no changes in age, gender, witnessed status, shockable rhythm or place of OHCA during the time periods. Bystander CPR increased over time, 59% in interval 1992-1998, versus 74% in interval 2006-2012 (p=0.005). There was a decrease in delay between OHCA and calling for the Emergency Medical Service (EMS) over the years, while calling for the EMS to arrival increased in terms of time. Survival to hospital admission appears to have increased over the years (p=0.009), whereas survival to one month did not change significantly over time. In a multivariate analysis, witnessed status, female gender, bystander CPR, place-home and EMS response time were associated with survival to hospital admission. For survival to one month, place, age, shockable rhythm and logarithmised delay from calling for an ambulance to arrival were of significance for survival. CONCLUSION: In OHCA due to drowning, over a period of 20 years, bystanders have called for help at an earlier stage and administered CPR more frequently in the past few years. Survival to hospital admission has increased, while shockable rhythm and early arrival of the EMS appear to be the most important factors for survival to one month.

Tidskriftsartikel (refereegranskat)abstract
- AIM: The aim of this study is to determine the prevalence of cardiac disease and its relationship to the victim's probable intent among patients with cardiac arrest due to drowning. METHOD: Retrospective autopsied drowning cases reported to the Swedish National Board of Forensic Medicine between 1990 and 2010 were included, alongside reported and treated out-of-hospital cardiac arrests due to drowning from the Swedish Out of Hospital Cardiac Arrest Registry that matched events in the National Board of Forensic Medicine registry (n = 272). RESULTS: Of 2166 drowned victims, most (72%) were males; the median age was 58 years (interquartile range, 42-71 years). Drowning was determined to be accidental in 55%, suicidal in 28%, and murder in 0.5%, whereas the intent was unclear in 16%. A contributory cause of death was found in 21%, and cardiac disease as a possible contributor was found in 9% of all autopsy cases. Coronary artery sclerosis (5%) and myocardial infarction (2%) were most frequent. Overall, cardiac disease was found in 14% of all accidental drownings, as compared with no cases (0%) in the suicide group; P = .05. Ventricular fibrillation was found to be similar in both cardiac and noncardiac cases (7%). This arrhythmia was found in 6% of accidents and 11% of suicides (P = .23). CONCLUSION: Among 2166 autopsied cases of drowning, more than half were considered to be accidental, and less than one-third, suicidal. Among accidents, 14% were found to have a cardiac disease as a possible contributory factor; among suicides, the proportion was 0%. The low proportion of cases showing ventricular fibrillation was similar, regardless of the presence of a cardiac disease.

- 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.
