- BACKGROUND: There have been few studies of the outcome in elderly patients who have suffered in-hospital cardiac arrest (IHCA) and the association between cardiac arrest characteristics and survival.AIM: The aim of this large observational study was to investigate the survival and neurological outcome in the elderly after IHCA, and to identify which factors were associated with survival.METHODS: We investigated elderly IHCA patients (≥70years of age) who were registered in the Swedish Cardiopulmonary Resuscitation Registry 2007-2015. For descriptive purposes, the patients were grouped according to age (70-79, 80-89, and ≥90years). Predictors of 30-day survival were identified using multivariable analysis.RESULTS: Altogether, 11,396 patients were included in the study. Thirty-day survival was 28% for patients aged 70-79 years, 20% for patients aged 80-89 years, and 14% for patients aged ≥90years. Factors associated with higher survival were: patients with an initially shockable rhythm, IHCA at an ECG-monitored location, IHCA was witnessed, IHCA during daytime (8 a.m.-8 p.m.), and an etiology of arrhythmia. A lower survival was associated with a history of heart failure, respiratory insufficiency, renal dysfunction and with an etiology of acute pulmonary oedema. Patients over 90 years of age with VF/VT as initial rhythm had a 41% survival rate. We found a trend indicating a less aggressive care with increasing age during cardiac arrest (fewer intubations, and less use of adrenalin and anti-arrhythmic drugs) but there was no association between age and delay in starting cardiopulmonary resuscitation (CPR). In survivors, there was no significant association between age and a favourable neurological outcome (CPC score: 1-2) (92%, 93%, and 88% in the three age groups, respectively).CONCLUSIONS: Increasing age among the elderly is associated with a lower 30-day survival after IHCA. Less aggressive treatment and a worse risk profile might contribute to these findings. Relatively high survival rates among certain subgroups suggest that discussions about advanced directives should be individualized. Most survivors have good neurological outcome, even patients over 90 years of age.

- BACKGROUND: The clinical effect of routine oxygen therapy in patients with suspected acute myocardial infarction who do not have hypoxemia at baseline is uncertain. METHODS: In this registry-based randomized clinical trial, we used nationwide Swedish registries for patient enrollment and data collection. Patients with suspected myocardial infarction and an oxygen saturation of 90% or higher were randomly assigned to receive either supplemental oxygen (6 liters per minute for 6 to 12 hours, delivered through an open face mask) or ambient air. RESULTS: A total of 6629 patients were enrolled. The median duration of oxygen therapy was 11.6 hours, and the median oxygen saturation at the end of the treatment period was 99% among patients assigned to oxygen and 97% among patients assigned to ambient air. Hypoxemia developed in 62 patients (1.9%) in the oxygen group, as compared with 254 patients (7.7%) in the ambient-air group. The median of the highest troponin level during hospitalization was 946.5 ng per liter in the oxygen group and 983.0 ng per liter in the ambient-air group. The primary end point of death from any cause within 1 year after randomization occurred in 5.0% of patients (166 of 3311) assigned to oxygen and in 5.1% of patients (168 of 3318) assigned to ambient air (hazard ratio, 0.97; 95% confidence interval [CI], 0.79 to 1.21; P=0.80). Rehospitalization with myocardial infarction within 1 year occurred in 126 patients (3.8%) assigned to oxygen and in 111 patients (3.3%) assigned to ambient air (hazard ratio, 1.13; 95% CI, 0.88 to 1.46; P=0.33). The results were consistent across all predefined subgroups. CONCLUSIONS: Routine use of supplemental oxygen in patients with suspected myocardial infarction who did not have hypoxemia was not found to reduce 1-year all-cause mortality.

Journal article (peer-reviewed)abstract
- Background: There has been in increase in the use of systems for organizing lay responders for suspected out-of-hospital cardiac arrests (OHCAs) dispatch using smartphone-based technology. The purpose is to increase survival rates; however, such systems are dependent on people's commitment to becoming a lay responder. Knowledge about the characteristics of such volunteers and their motivational factors is lacking. Therefore, we explored characteristics and quantified the underlying motivational factors for joining a smartphone-based cardiopulmonary resuscitation (CPR) lay responder system. Methods: In this descriptive cross-sectional study, 800 consecutively recruited lay responders in a smartphone-based mobile positioning first-responder system (SMS-lifesavers) were surveyed. Data on characteristics and motivational factors were collected, the latter through a modified version of the validated survey "Volunteer Motivation Inventory" (VMI). The statements in the VMI, ranked on a Likert scale (1-5), corresponded to(a) intrinsic (an inner belief of doing good for others) or (b) extrinsic (earning some kind of reward from the act) motivational factors. Results: A total of 461 participants were included in the final analysis. Among respondents, 59% were women, 48% between 25 and 39 years of age, 37% worked within health care, and 66% had undergone post-secondary school. The most common way (44%) to learn about the lay responder system was from a CPR instructor. A majority (77%) had undergone CPR training at their workplace. In terms of motivation, where higher scores reflect greater importance to the participant, intrinsic factors scored highest, represented by the category values (mean 3.97) followed by extrinsic categories reciprocity (mean 3.88) and self-esteem (mean 3.22). Conclusion: This study indicates that motivation to join a first responder system mainly depends on intrinsic factors, i.e. an inner belief of doing good, but there are also extrinsic factors, such as earning some kind of reward from the act, to consider. Focusing information campaigns on intrinsic factors may be the most important factor for successful recruitment. When implementing a smartphone-based lay responder system, CPR instructors, as a main information source to potential lay responders, as well as the workplace, are crucial for successful recruitment.

Journal article (peer-reviewed)abstract
- BACKGROUND: In the DETO2X-AMI trial (Determination of the Role of Oxygen in Suspected Acute Myocardial Infarction), we compared supplemental oxygen with ambient air in normoxemic patients presenting with suspected myocardial infarction and found no significant survival benefit at 1 year. However, important secondary end points were not yet available. We now report the prespecified secondary end points cardiovascular death and the composite of all-cause death and hospitalization for heart failure. METHODS: In this pragmatic, registry-based randomized clinical trial, we used a nationwide quality registry for coronary care for trial procedures and evaluated end points through the Swedish population registry (mortality), the Swedish inpatient registry (heart failure), and cause of death registry (cardiovascular death). Patients with suspected acute myocardial infarction and oxygen saturation of >= 90% were randomly assigned to receive either supplemental oxygen at 6 L/min for 6 to 12 hours delivered by open face mask or ambient air. RESULTS: A total of 6629 patients were enrolled. Acute heart failure treatment, left ventricular systolic function assessed by echocardiography, and infarct size measured by high-sensitive cardiac troponin T were similar in the 2 groups during the hospitalization period. All-cause death or hospitalization for heart failure within 1 year after randomization occurred in 8.0% of patients assigned to oxygen and in 7.9% of patients assigned to ambient air (hazard ratio, 0.99; 95% CI, 0.84-1.18; P=0.92). During long-term follow-up (median [range], 2.1 [1.0-3.7] years), the composite end point occurred in 11.2% of patients assigned to oxygen and in 10.8% of patients assigned to ambient air (hazard ratio, 1.02; 95% CI, 0.88-1.17; P=0.84), and cardiovascular death occurred in 5.2% of patients assigned to oxygen and in 4.8% assigned to ambient air (hazard ratio, 1.07; 95% CI, 0.87-1.33; P=0.52). The results were consistent across all predefined subgroups. CONCLUSIONS: Routine use of supplemental oxygen in normoxemic patients with suspected myocardial infarction was not found to reduce the composite of all-cause mortality and hospitalization for heart failure, or cardiovascular death within 1 year or during long-term follow-up.

- Circulating neutrophil gelatinase-associated lipocalin (NGAL) concentration increases in cardiovascular disease, but the long-term prognostic value of NGAL concentration has not been evaluated in acute coronary syndrome (ACS). We examined the association between NGAL concentration and prognosis in patients with ACS after non-ST-elevation myocardial infarction (NSTEMI) or STEMI.NGAL concentration was measured in blood from 1121 consecutive ACS patients (30% women, mean age 65 years) on the first morning after admission. After adjustment for 14 variables, NGAL concentration predicted long-term (median 167 months) mortality (hazard ratio [HR] 1.33, 95% confidence interval [CI] 1.10-1.61, P = 0.003) for quartile (q) 4 of NGAL concentration. NGAL concentrations also predicted long-term mortality (HR = 1.63, 95% CI 1.31-2.03, P < 0.001, N = 741) when adjusting for Global Registry of Acute Coronary Events (GRACE) score, left ventricular ejection fraction (LVEF), and pro-B-type natriuretic peptide (proBNP) and C-reactive protein (CRP) concentrations. With these adjustments, NGAL concentration predicted long-term mortality in NSTEMI patients (HR = 2.02, 95% CI 1.50-2.72, P < 0.001) but not in STEMI patients (HR = 1.32, 95% CI 0.95-1.83, P = 0.100). In all patients, the combination of NGAL concentration and GRACE score yielded an HR of 5.56 (95% CI 4.37-7.06, P < 0.001) for q4/q4 for both variables.NGAL concentration in ACS is associated with long-term prognosis after adjustment for clinical confounders. Measuring circulating NGAL concentration may help to identify patients-particularly those with NSTEMI-needing closer follow-up after ACS.

Prehospital ECG signs of acute coronary occlusion are associated with reduced one-year motality
- 2013
-
In: International Journal of Cardiology. - : Elsevier Ireland Ltd. - 0167-5273 .- 1874-1754. ; 168:4, s. 3594-3598

Journal article (peer-reviewed)abstract
- BACKGROUND: We wanted to evaluate predictors of direct admittance to a coronary care unit (CCU) and predictors of death in patients with suspected acute coronary syndromes (ACS). METHODS: During 2004-2007, all consecutive prehospitally triaged patients with suspected ACS were prospectively included. Prehospital and emergency data were collected at point of care. Data from medical records, ECG-, echocardiography- and laboratory databases was collected retrospectively. RESULTS: In all, 2757 patients were included. Out of these 858 were directly admitted to the CCU or cath/lab. Predictors for direct admittance to the CCU were ST-segment elevation on the initial ECG; odds ratio (OR) 46.11, left bundle branch block; OR 3.30, ongoing symptoms; OR 2.90, current smoking; OR 2.18 and ST-segment depression; OR 2.05. Independent predictors for 1-year mortality were cardiogenic shock; OR 14.40, increasing age OR (per year) 1.08, diabetes; OR 2.09 and chronic heart failure; OR 1.67. ST-segment elevation was associated with a lower 1-year mortality rate; OR 0.52. CONCLUSIONS: Among patients with a suspected ACS, prehospital ECG-signs indicating an acute coronary occlusion were not only a predictor for direct admission to acute coronary care but also a predictor for increased survival. To improve future outcome in acute ischemic heart diseases we must find and treat not only the STEMI's but also the high-risk NSTEMIs that otherwise would have a poor prognosis.

- Objective Identify differences in the early treatment of acute chest pain patients with regard to the language proficiency of patients and thus identify opportunities for improving equity in cardiac care. Design Retrospective cross-sectional study comparing care delivered to Swedish-speaking (SS) and non-Swedish-speaking (NSS) patients. Setting A Swedish university hospital that provides highly specialized care to 1.6 million inhabitants. Participants All patients with acute chest pain or symptoms suggestive of acute coronary syndrome who sought care between mid-September and mid-December 2008 (2588 visits). Missing data on the patient group to which study subjects belonged were 2% (45 visits). NSS represented 8% of the 2543 visits (NSS = 2334; NNSS = 209). Main Outcome Measure(s) Delay times from arrival in hospital to admission to catheterization laboratory or ward (ΔTHOSP-PCI), first physical contact to first electrocardiogram (ΔTCONTACT-ECG), first physical contact to first aspirin (ΔTCONTACT-ASA) and arrival in hospital to coronary angiography (ΔTHOSP-ANGIO). Also included baseline characteristics of patients, diagnosis and findings in hospital and secondary preventive activities. Results The median ΔTHOSP-PCI was longer for NSS by 43 min [254 versus 211, 95% confidence interval (CI), odds ratio (OR) = (1.3; 2.8)]. The median ΔTCONTACT-ECG and ΔTHOSP-ANGIO were longer for NSS by 4 min [17 versus 13, 95% CI, OR = (0.8; 1.8)] and 14 h [44 versus 30, 95% CI, OR = (0.6; 3.6)], respectively. Conversely, the median ΔTCONTACT-ASA was longer for SS by 20 min [81 versus 61, 95% CI, OR = (0.3; 1.6)]. Conclusions Poorer language proficiency was associated with longer delay time from arrival in hospital to admission to catheterization laboratory or ward. No other delay times were found to be statistically significantly different with respect to the language proficiency of patients.
