- BACKGROUND: Triple antithrombotic therapy with warfarin plus two antiplatelet agents is the standard of care after percutaneous coronary intervention (PCI) for patients with atrial fibrillation, but this therapy is associated with a high risk of bleeding.METHODS: inhibitor (clopidogrel or ticagrelor) and no aspirin (110-mg and 150-mg dual-therapy groups). Outside the United States, elderly patients (≥80 years of age; ≥70 years of age in Japan) were randomly assigned to the 110-mg dual-therapy group or the triple-therapy group. The primary end point was a major or clinically relevant nonmajor bleeding event during follow-up (mean follow-up, 14 months). The trial also tested for the noninferiority of dual therapy with dabigatran (both doses combined) to triple therapy with warfarin with respect to the incidence of a composite efficacy end point of thromboembolic events (myocardial infarction, stroke, or systemic embolism), death, or unplanned revascularization.RESULTS: The incidence of the primary end point was 15.4% in the 110-mg dual-therapy group as compared with 26.9% in the triple-therapy group (hazard ratio, 0.52; 95% confidence interval [CI], 0.42 to 0.63; P<0.001 for noninferiority; P<0.001 for superiority) and 20.2% in the 150-mg dual-therapy group as compared with 25.7% in the corresponding triple-therapy group, which did not include elderly patients outside the United States (hazard ratio, 0.72; 95% CI, 0.58 to 0.88; P<0.001 for noninferiority). The incidence of the composite efficacy end point was 13.7% in the two dual-therapy groups combined as compared with 13.4% in the triple-therapy group (hazard ratio, 1.04; 95% CI, 0.84 to 1.29; P=0.005 for noninferiority). The rate of serious adverse events did not differ significantly among the groups.CONCLUSIONS: inhibitor, and aspirin. Dual therapy was noninferior to triple therapy with respect to the risk of thromboembolic events. (Funded by Boehringer Ingelheim; RE-DUAL PCI ClinicalTrials.gov number, NCT02164864)

- OBJECTIVE: The primary aim of this study was to systematically compare perceived sleep quality, sleeplessness behavior, sense of mastery, self-esteem, depression, subjective health, and effects of sleep loss in men and women with stable coronary artery disease (CAD). Further aims were to determine possible predictors of poor sleep quality and sense of mastery, as well as the consequences of too little sleep. METHODS: Comparative-correlation and predictive design were used. Patients with a history of stable angina pectoris scheduled to undergo coronary angiography at Linköping University Hospital in Sweden were included. There were 47 women and 88 men (mean age 62.4 years) with CAD. Structured interviews using validated questionnaires covered sleep quality and sleep habits, effects of sleep loss, psychologic resources, and depression. RESULTS: Multiple stepwise regression analysis showed that sleeplessness behavior, depressed mood, female gender, and pharmacologic treatments with inflammation inhibitors significantly (P < .0001) accounted for the variance of poorer sleep quality. The analysis also showed that the following factors in descending order significantly accounted (P < .0001) for the outcome of sleep quality: inability to feel refreshed by sleep, difficulty in maintaining sleep, gastrointestinal problems, too little sleep, final morning awakening time, sleep onset latency, lying down because of daytime tiredness, and daytime physical tiredness. CONCLUSIONS: Compared with men, women with stable CAD may be especially at risk of experiencing poor sleep quality, even when sleeplessness behavior and pharmacologic treatments with inflammation inhibitors are controlled. It is also possible that they may be more at risk of depressed mood. Copyright © 2006 by Mosby, Inc.

- Aim: Research focusing on hyperarousability in association with general sensitivity to stress has increased. This study aimed to: (i) describe values for self-reported hyperarousal behaviour traits, depression, sleeplessness behaviour and health-related quality of life [The Short Form 36 Health Survey Questionnaire (SF-36)] in a gender-stratified random sample from the Swedish population, and (ii) test the validity and reliability of the Swedish version of the Hyperarousal Behavioural Trait Scale (H-scale). Methods: In this study, 402 women and 391 men from Sweden were included. A test-retest study was performed on 297 subjects. Results: The total mean score on the H-scale was 29.5 (SD 10.0, 95% CI 28.8-30.2). Compared to men, women scored higher on the H-scale (total score, sub-scales and many items), whereas no evidence of an age trend was seen. The H-scale has proven to be a valid and reliable scale. Pearson's correlation coefficient showed similar magnitude and direction between the H-scale and the Zung's Self-rating Depression Scale, as between the H-scale and the Vicious Cycle of Sleeplessness Behaviour Scale, Vitality, Mental Health and the Mental Component Summary index on the SF-36 respectively. The Cronbach's alpha for the H-scale was 0.84 and estimated stability test-retest point of time varies between 0.73 and 0.80. Conclusions: This study indicates gender differences in response style in association with altered health-related quality of life. The H-scale is a valid and reliable self-reported scale for measuring hyperarousal behavioural trait research outcome in clinical practice. © 2006 Nordic College of Caring Science.

- Introduction: Breathlessness is common in the population, especially in women and associated with adverse health outcomes. Obesity (body mass index (BMI) >30 kg/m(2)) is rapidly increasing globally and its impact on breathlessness is unclear.Methods: This population-based study aimed primarily to evaluate the association of current BMI and self-reported change in BMI since age 20 with breathlessness (modified Research Council score >= 1) in the middle-aged population. Secondary aims were to evaluate factors that contribute to breathlessness in obesity, including the interaction with spirometric lung volume and sex.Results: We included 13 437 individuals; mean age 57.5 years; 52.5% women; mean BMI 26.8 (SD 4.3); mean BMI increase since age 20 was 5.0 kg/m(2); and 1283 (9.6%) reported breathlessness. Obesity was strongly associated with increased breathlessness, OR 3.54 (95% CI, 3.03 to 4.13) independent of age, sex, smoking, airflow obstruction, exercise level and the presence of comorbidities. The association between BMI and breathlessness was modified by lung volume; the increase in breathlessness prevalence with higher BMI was steeper for individuals with lower forced vital capacity (FVC). The higher breathlessness prevalence in obese women than men (27.4% vs 12.5%; p<0.001) was related to their lower FVC. Irrespective of current BMI and confounders, individuals who had increased in BMI since age 20 had more breathlessness.Conclusion: Breathlessness is independently associated with obesity and with weight gain in adult life, and the association is stronger for individuals with lower lung volumes.

- A framework is needed for identifying internal and external factors essential for the nursing management of psychological supportive health care and education for patients' self-care in sleep. In order to generate more knowledge from the patient's perspective, the aim of this study was to describe how patients with coronary artery disease (CAD) perceive that their sleep is influenced by rest, activity and health in outpatient care. Qualitative interviews were performed with 33 outpatients. The data were analysed using a phenomenographic method. Three descriptive categories of the phenomenon were described: my lifestyle is reflected in my sleep behaviour, handling the practices around tiredness and sleep, and feelings of negative and positive efficacy. Feelings of tiredness, fatigue and sleepiness were different pre-sleep stages, but were also related to the patient's adaptation and recovery. Creating one's own personal time and feelings of efficacy gave an inner sense of strength which is indicated as being particularly important in managing stress and the demands of everyday life in a satisfactory manner. From a contextual, holistic perspective on health, it is important to identify the patient's needs, symptoms and intentional or unintentional self-care management strategies regarding sleep and lifestyle. To promote a positive health outcome it is essential to identify sleeplessness behaviour and perceived self-efficacy for self-care in sleep. © 2007 Nordic College of Caring Science.

- Many women with typical anginal chest pain have normal coronary angiograms, which may be due to altered endothelial function. We evaluated the endothelial markers cyclic GMP (cGMP) and immunoreactive endothelin (ir-ET) regarding presence of coronary atherosclerosis in women with clinical signs of unstable coronary artery disease (CAD). Plasma levels of cGMP and ir-ET were determined in 118 patients and 84 controls. Ischaemia was evaluated at an exercise test. Of the patients 20% had normal vessels, 14% insignificant CAD and 66% significant stenosis at coronary angiography. Mean (95% CI) concentration of cGMP (nmol/l) was higher in patients than in controls (5.05 (4.53; 5.58) vs. 3.79 (3.34; 4.23)). Separating patients according to daily intake of nitroglycerin, only patients with this medication had significantly higher cGMP level (5.73 (4.88; 6.58)), whereas the difference between those without (4.35 (3.76; 4.94)) and controls disappeared. Patients with ischaemia at exercise test had higher cGMP level than those without (6.01 (5.13; 6.88) vs. 4.30 (3.66; 4.94)), even after adjusting for nitroglycerin treatment. ir-ET (pmol/l) was lower in patients with normal vessels than patients with coronary atherosclerosis (0.83 (0.78; 0.88) vs. 0.98 (0.92; 1.04)) and than the control group (0.91 (0.87; 0.94)). The difference between the control group and patients with atherosclerosis was also significant. Patients with unstable CAD and long-term nitroglycerin treatment have increased cGMP level. Patients with exercise-induced ischaemia have higher cGMP level than those without, irrespective of nitroglycerin treatment, which may reflect a general compensatory mechanism. Patients with normal vessels have low level of ir-ET, indicating different mechanisms for ischaemia/angina in these patients compared with patients with atherosclerosis.

- Background: The purpose of this study is to investigate the impact of oxygen therapy on cardiovascular outcomes in relation to sex in patients with confirmed myocardial infarction (MI).Methods: The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction trial randomized 6,629 patients to oxygen at 6 L/min for 6-12 hours or ambient air. In the present subgroup analysis including 5,010 patients (1,388 women and 3,622 men) with confirmed MI, we report the effect of supplemental oxygen on the composite of all-cause death, rehospitalization with MI, or heart failure at long-term follow-up, stratified according to sex.Results: Event rate for the composite endpoint was 18.1% in women allocated to oxygen, compared to 21.4% in women allocated to ambient air (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.65-1.05). In men, the incidence was 13.6% in patients allocated to oxygen compared to 13.3% in patients allocated to ambient air (HR 1.03, 95% CI 0.86-1.23). No significant interaction in relation to sex was found (P=.16). Irrespective of allocated treatment, the composite endpoint occurred more often in women compared to men (19.7 vs 13.4%, HR 1.51; 95% CI, 1.30-1.75). After adjustment for age alone, there was no difference between the sexes (HR 1.06, 95% CI 0.91-1.24), which remained consistent after multivariate adjustment.Conclusion: Oxygen therapy in normoxemic MI patients did not significantly affect all-cause mortality or rehospitalization for MI or heart failure in women or men. The observed worse outcome in women was explained by differences in baseline characteristics, especially age

- Elevated body weight in adolescence is associated with early cardiovascular disease, but whether this association is traceable to weight in early adulthood, weight in midlife or to weight gain is not known. The aim of this study is to assess the risk of midlife coronary atherosclerosis being associated with body weight at age 20, body weight in midlife and body weight change.We used data from 25,181 participants with no previous myocardial infarction or cardiac procedure in the Swedish CArdioPulmonary bioImage Study (SCAPIS, mean age 57 years, 51% women). Data on coronary atherosclerosis, self-reported body weight at age 20 and measured midlife weight were recorded together with potential confounders and mediators. Coronary atherosclerosis was assessed using coronary computed tomography angiography (CCTA) and expressed as segment involvement score (SIS).The probability of having coronary atherosclerosis was markedly higher with increasing weight at age 20 and with mid-life weight (p<0.001 for both sexes). However, weight increase from age 20 until mid-life was only modestly associated with coronary atherosclerosis. The association between weight gain and coronary atherosclerosis was mainly seen in men. However, no significant sex difference could be detected when adjusting for the 10-year delay in disease development in women.Similar in men and women, weight at age 20 and weight in midlife are strongly related to coronary atherosclerosis while weight increase from age 20 until midlife is only modestly related to coronary atherosclerosis.

- BACKGROUND:Patients in clinical trials of fibrinolytic agents have been shown to be younger, less often female, and to have lower risk characteristics and a better outcome compared with unselected patients with ST-elevation myocardial infarction. However, a direct comparison of patients treated with fibrinolytic agents and not enrolled versus those enrolled in a trial, including a large number of patients, has not been performed.METHODS:Prospective data from the Swedish Register of Cardiac Intensive Care on patients admitted with acute myocardial infarction treated with thrombolytic agents in 60 Swedish hospitals were linked to data on trial participants in the ASsessment of Safety and Efficacy of a New Thrombolytic (ASSENT)-2 trial of fibrinolytic agents. Baseline characteristics, treatments, and long-term outcome were evaluated in 729 trial participants (A2), 2048 nonparticipants at trial hospitals (non-A2), and 964 nonparticipants at other hospitals (non-A2-Hosp).RESULTS:Nontrial patients compared with A2 patients were older and had higher risk characteristics and more early complications, although the treatments were similar. Patients at highest risk of death were the least likely to be enrolled in the trial. The 1-year mortality rate was 8.8% versus 20.3% and 19.0% (P <.001 for both) among A2 compared with non-A2 and non-A2-Hosp patients, respectively. After adjustment for a number of risk factors, the 1-year mortality rate was still twice as high in nontrial compared with A2 patients.CONCLUSIONS:The adjusted 1-year mortality rate was twice as high in patients treated with fibrinolytic agents and not enrolled in a clinical trial compared with those enrolled. One major reason for the difference in outcome appeared to be the selection of less critically ill patients to the trial.

Tidskriftsartikel (refereegranskat)abstract
- Background: Different regional depots of fat have distinct metabolic properties and may relate differently to adverse cardiac remodeling. We sought to quantify regional depots of body fat and to investigate their relationship to cardiac structure and function in Type 2 Diabetes (T2D) and controls.Methods: From the SCAPIS cohort in Linköping, Sweden, we recruited 92 subjects (35% female, mean age 59.5 ± 4.6 years): 46 with T2D and 46 matched controls. In addition to the core SCAPIS data collection, participants underwent a comprehensive magnetic resonance imaging examination at 1.5 T for assessment of left ventricular (LV) structure and function (end-diastolic volume, mass, concentricity, ejection fraction), as well as regional body composition (liver proton density fat fraction, visceral adipose tissue, abdominal subcutaneous adipose tissue, thigh muscle fat infiltration, fat tissue-free thigh muscle volume and epicardial adipose tissue).Results: Compared to the control group, the T2D group had increased: visceral adipose tissue volume index (P < 0.001), liver fat percentage (P < 0.001), thigh muscle fat infiltration percentage (P = 0.02), LV concentricity (P < 0.001) and LV E/e'-ratio (P < 0.001). In a multiple linear regression analysis, a negative association between liver fat percentage and LV mass (St Beta -0.23, P < 0.05) as well as LV end-diastolic volume (St Beta -0.27, P < 0.05) was found. Epicardial adipose tissue volume and abdominal subcutaneous adipose tissue volume index were the only parameters of fat associated with LV diastolic dysfunction (E/e'-ratio) (St Beta 0.24, P < 0.05; St Beta 0.34, P < 0.01, respectively). In a multivariate logistic regression analysis, only visceral adipose tissue volume index was significantly associated with T2D, with an odds ratio for T2D of 3.01 (95% CI 1.28-7.05, P < 0.05) per L/m2 increase in visceral adipose tissue volume.Conclusions: Ectopic fat is predominantly associated with cardiac remodeling, independently of type 2 diabetes. Intriguingly, liver fat appears to be related to LV structure independently of VAT, while epicardial fat is linked to impaired LV diastolic function. Visceral fat is associated with T2D independently of liver fat and abdominal subcutaneous adipose tissue.

- Objective: In non-alcoholic fatty liver disease (NAFLD), liver fibrosis is the strongest predictor of adverse outcomes. We sought to investigate the relationship between liver fibrosis and cardiac remodeling in participants from the general population using magnetic resonance imaging (MRI), as well as explore potential mechanistic pathways by analyzing circulating cardiovascular biomarkers.Methods: In this cross-sectional study, we prospectively included participants with type 2 diabetes and individually matched controls from the SCAPIS (Swedish CArdioPulmonary bioImage Study) cohort in Linköping, Sweden. Between November 2017 and July 2018, participants underwent MRI at 1.5 Tesla for quantification of liver proton density fat fraction (spectroscopy), liver fibrosis (stiffness from elastography), left ventricular (LV) structure and function, as well as myocardial native T1 mapping. We analyzed 278 circulating cardiovascular biomarkers using a Bayesian statistica lapproach.Results: In total, 92 participants were enrolled (mean age 59.5 ± 4.6 years, 32 women). The mean liver stiffness was 2.1 ± 0.4 kPa. 53 participants displayed hepatic steatosis. LV concentricity increased across quartiles of liver stiffness. Neither liver fat nor liver stiffness displayed any relationships to myocardial tissue characteristics (native T1). In a regression analysis, liver stiffness was related to increased LV concentricity. This association was independent of diabetes and liver fat (Beta = 0.26, p = 0.0053), but was attenuated (Beta = 0.17, p = 0.077) when also adjusting for circulating levels of interleukin-1 receptor type 2.Conclusion: MRI reveals that liver fibrosis is associated to structural LV remodeling, in terms of increased concentricity, in participants from the general population. This relationship could involve the interleukin-1 signaling.
