- The purpose of this study was to describe type A behavior pattern and trait anger in patients with myocardial infarction with nonobstructive coronary arteries (MINOCA) and compare them with patients with coronary heart disease and healthy controls. Type A behavior pattern and anger have been linked to coronary heart disease in previous studies. This is the first study to assess type A behavior pattern and trait anger in MINOCA patients.One hundred MINOCA patients, consecutively recruited during 2007-2011 at 5 coronary care units in Stockholm, were matched for sex and age to 100 coronary heart disease patients and 100 healthy controls. All participants completed the Bortner Rating Scale to quantify type A behavior pattern and the Spielberger Trait Anger Scale to quantify anger 3 months after the acute event.MINOCA patients' Bortner Rating Scale score was 70.9 ± 10.8 (mean ± SD) and Spielberger Trait Anger Scale score was 14 (12-17) (median; interquartile range). Coronary heart disease patients' Bortner Rating Scale score was 70.5 ± 10.2 and Spielberger Trait Anger Scale score was 14 (12-17). Healthy controls' Bortner Rating Scale score was 71.9 ± 9.1 and Spielberger Trait Anger Scale score was 13 (11-16).We found no significant differences in Bortner Rating Scale score and Spielberger Trait Anger Scale score among MINOCA, coronary heart disease patients, and healthy controls, regardless of whether total scores, subscales, or cutoffs were used to classify type A behavior pattern and trait anger. However, we cannot exclude the existence of an occasional episode of anger or mental stress in relation to the coronary event. This is the first study to assess type A behavior pattern and trait anger in patients with MINOCA, and future studies need to confirm the current findings before any firm conclusions can be made.

- OBJECTIVE: Although the causality of the obesity—hypertension association is established, the potential for prevention is not. We hypothesized that weight gain between early adulthood and mid-life is associated with higher mid-life blood pressure.METHODS: We investigated the hypothesis using a large contemporaneous population-based mid-life cohort of men and women aged 50-64 years. Recalled body weight at age 20 years was self-reported, and mid-life body weight and office blood pressures were measured in accordance with a detailed protocol.RESULTS: On average, men had gained 14.9 (95% CI 14.6-15.2) kg of weight, and women 14.6 (95% CI 14.4-14.9) kg, between age 20 years and the mid-life examination, corresponding to 0.40 (95% CI 0.39-0.41) kg/year for men and women. Both weight at age 20 years and weight at the mid-life examination were associated with mid-life blood pressures. On average, a 10 kg weight increase between age 20 years and mid-life was associated with 2.2 (95% CI 0.9-3.5) mmHg higher systolic and 1.7 (95% CI 0.9-2.5) mmHg higher diastolic mid-life blood pressure in men, and 3.2 (2.5-4.0) mmHg higher systolic and 2.4 (1.9-2.9) mmHg higher diastolic mid-life blood pressure in women. Mid-life weight was more closely associated than weight at age 20 years with mid-life blood pressure. For a given mid-life weight, blood pressure was higher in persons with higher weight gain from age 20 years.CONCLUSION: In sum, weight gain between early adulthood and mid-life was associated with higher mid-life blood pressure. The magnitude of the association indicates a potentially great public health impact of strategies to prevent weight gain throughout adulthood.

- Reduced lung function is associated with cardiovascular mortality, but the relationships with atherosclerosis are unclear. The population-based Swedish CArdioPulmonary BioImage study measured lung function, emphysema, coronary CT angiography, coronary calcium, carotid plaques and ankle-brachial index in 29,593 men and women aged 50–64 years. The results were confirmed using 2-sample Mendelian randomization. Lower lung function and emphysema were associated with more atherosclerosis, but these relationships were attenuated after adjustment for cardiovascular risk factors. Lung function was not associated with coronary atherosclerosis in 14,524 never-smokers. No potentially causal effect of lung function on atherosclerosis, or vice versa, was found in the 2-sample Mendelian randomization analysis. Here we show that reduced lung function and atherosclerosis are correlated in the population, but probably not causally related. Assessing lung function in addition to conventional cardiovascular risk factors to gauge risk of subclinical atherosclerosis is probably not meaningful, but low lung function found by chance should alert for atherosclerosis.

- Background: Several studies have shown that metabolic surgery is associated with remission of diabetes and hypertension. In terms of diabetes, factors such as duration, insulin use, weight loss, and age have been shown to contribute to the likelihood of remission. Such factors have not been determined for hypertension. The aim of this study was to evaluate factors associated with the remission and relapse of hypertension after metabolic surgery, as well as the risk for major adverse cardiovascular event (MACE) and mortality in patients with and without remission.Methods and findings: All adults who underwent metabolic surgery between January 2007 and June 2016 were identified in the nationwide Scandinavian Obesity Surgery Registry (SOReg). Through cross-linkage with the Swedish Prescribed Drug Register, Patient Register, and Statistics Sweden, individual data on prescriptions, inpatient and outpatient diagnoses, and mortality were retrieved. Of the 15,984 patients with pharmacologically treated hypertension, 6,286 (39.3%) were in remission at 2 years. High weight loss and male sex were associated with higher chance of remission, while duration, number of antihypertensive drugs, age, body mass index (BMI), cardiovascular disease, and dyslipidemia were associated with lower chance. After adjustment for age, sex, BMI, comorbidities, and education, the cumulative probabilities of MACEs (2.8% versus 5.7%, adjusted odds ratio (OR) 0.60, 95% confidence interval (CI) 0.47 to 0.77, p < 0.001) and all-cause mortality (4.0% versus 8.0%, adjusted OR 0.71, 95% CI 0.57 to 0.88, p = 0.002) were lower for patients being in remission at 2 years compared with patients not in remission, despite relapse of hypertension in 2,089 patients (cumulative probability 56.3%) during 10-year follow-up. The main limitations of the study were missing information on nonpharmacological treatment for hypertension and the observational study design.Conclusions: In this study, we observed an association between high postoperative weight loss and male sex with better chance of remission, while we observed a lower chance of remission depending on disease severity and presence of other metabolic comorbidities. Patients who achieved remission had a halved risk of MACE and death compared with those who did not. The results suggest that in patients with severe obesity and hypertension, metabolic surgery should not be delayed.Author summary:Why was this study done?Hypertension, particularly in combination with morbid obesity, is a leading cause of mortality and disability worldwide.There is a growing body of evidence supporting the reduction of major adverse cardiovascular events (MACEs) and mortality among patients with metabolic comorbidities after bariatric surgery. Less is known of the factors associated with remission and relapse of disease as well as the impact on MACEs and morality from reaching remission.The main purpose of this study was to assess which factors that contribute to the remission and relapse of hypertension after metabolic surgery, as well as the risk for MACE and mortality in patients who have achieved remission of hypertension.What did the researchers do and find?In this nationwide observational study, 15,984 patients with hypertension undergoing a primary metabolic procedure were included.Almost 40% of patients with hypertension experienced remission of hypertension 2 years after surgery. While 56% relapsed over 10-year follow-up, those who reached remission experienced lower probability for MACEs and all-cause mortality compared with those who did not reach remission.What do these findings mean?The results of this study suggest that metabolic surgery has the highest success rate for patients early in the course of disease and thus suggests that metabolic surgery should not be delayed for patients with severe obesity and hypertension.

- Background: Patients on dialysis who have an acute myocardial infarction (AMI) have an exceedingly poor prognosis, but it is unknown to what extent guideline-recommended interventions and treatments are used and to which benefit. We aimed to assess temporal changes in the use of treatments and survival rates in dialysis patients with an AMI.Methods and Results: All consecutive AMI cases from 1996 to 2013 enrolled in the SWEDEHEART registry (Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) were included. The Swedish Renal Registry identified all chronic dialysis cases. Multivariable adjusted standardized 1-year mortality was estimated. An age-sex-calendar year-matched dialysis background population from the Swedish Renal Registry was used to obtain a standardized incidence ratio. All analyses were performed in 2-year blocks, where each individual could be included several times but in different time blocks; hence the term AMI cases and not patients is used. Of 289 699 cases with AMI, 1398 (0.5%) were on dialysis (73.6% hemodialysis; 26.4% peritoneal dialysis). Among dialysis cases, 29.4% were women, and 21.0% had ST-segment-elevation myocardial infarction. Through 1996 to 2013, dialysis cases had similar age (median, 70 years [interquartile range, 62-77]; P for trend, 0.14), but the proportion with diabetes mellitus increased (36.0%-55.3%; P for trend, 0.005). Dialysis cases admitted with AMI were treated more invasively and received more discharge medications in the later years. From 1995 to 2013, in-hospital and 1-year mortality decreased from 25.4% to 9.4% and from 59.6% to 41.2%, respectively. The standardized in-hospital and 1-year mortality decreased from 25.7% to 9.4% and from 54.6% to 41.2%. Yet, compared with the matched dialysis population, the odds of death remained as high in 2012/2013 as in 1996/1997 (odds ratio, 2.04; 95% CI, 1.62-2.58 and odds ratio, 1.99; 95% CI, 1.52-2.60, respectively; P for trend, 0.34).Conclusions: Over the last 18 years, more patients on dialysis with AMI have been treated with evidence-based therapies. Overall, dialysis cases with AMI have an improved in-hospital and 1-year survival in the more recent years compared with earlier years. However, this appears largely to be because of improved survival in the general dialysis population.

- Aims Optimal antithrombotic therapy after percutaneous coronary intervention (PCI) in patients with myocardial infarction (MI) and atrial fibrillation is uncertain. In this study, we compared antithrombotic regimes with regard to a composite cardiovascular outcome of all-cause mortality, MI or ischaemic stroke, and major bleeds. Methods and results Patients between October 2005 and December 2012 were identified in Swedish registries, n = 7116. Landmark 0-90 and 91-365 days of outcome were evaluated with Cox-regressions, with dual antiplatelet therapy as reference. At discharge, 16.2% received triple therapy (aspirin, clopidogrel, and warfarin), 1.9% aspirin plus warfarin, 7.3% clopidogrel plus warfarin, and 60.8% dual antiplatelets. For cardiovascular outcome, adjusted hazard ratio with 95% confidence interval (HR) for triple therapy was 0.86 (0.70-1.07) for 0-90 days and 0.78 (0.58-1.05) for 91-365 days. A HR of 2.16 (1.48-3.13) and 1.61 (0.98-2.66) during 0-90 and 91-365 days, respectively, was observed for major bleeds. For aspirin plus warfarin, HR 0.82 (0.54-1.26) and 0.62 (0.48-0.79) was observed for cardiovascular outcome and 1.30 (0.60-2.85) and 1.01 (0.63-1.62) for major bleeds during 0-90 and 91-365 days, respectively. For clopidogrel plus warfarin, HR of 0.90 (0.68-1.19) and 0.68 (0.49-0.95) was observed for cardiovascular outcome and 1.28 (0.71-2.32) and 1.08 (0.57-2.04) for major bleeds during 0-90 and 91-365 days, respectively. Conclusion Compared to dual antiplatelets, aspirin or clopidogrel plus warfarin therapy was associated with similar 0-90 days and lower 91-365 days of risk of the cardiovascular outcome, without higher risk of major bleeds. Triple therapy was associated with non-significant lower risk of cardiovascular outcome and higher risk of major bleeds.

- 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: 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.

- BACKGROUND Cardiac troponin is the preferred biomarker for diagnosing myocardial infarction (MI). OBJECTIVES The aim of this study was to examine the implications of introducing high-sensitivity cardiac troponin T (hs-cTnT) into clinical practice and to define at what hs-cTnT level risk starts to increase. METHODS We analyzed data from 48,594 patients admitted because of symptoms suggesting an acute coronary syndrome and who were entered into a large national registry. Patients were divided into Group 1, those with hs-cTnT <6 ng/l; Group 2, those with hs-cTnT 6 to 13 ng/l; Group 3, those with hs-cTnT 14 to 49 ng/l (i.e., a group in which most patients would have had a negative cardiac troponin T with older assays); and Group 4, those with hs-cTnT >= 50 ng/l. RESULTS There were 5,790 (11.9%), 6,491 (13.4%), 10,476 (21.6%), and 25,837 (53.2%) patients in Groups 1, 2, 3, and 4, respectively. In Groups 1 to 4, the proportions with MI were 2.2%, 2.6%, 18.2%, and 81.2%. There was a stepwise increase in the proportion of patients with significant coronary stenoses, left ventricular systolic dysfunction, and death during follow-up. When dividing patients into 20 groups according to hs-cTnT level, the adjusted mortality started to increase at an hs-cTnT level of 14 ng/l. CONCLUSIONS Introducing hs-cTnT into clinical practice has led to the recognition of a large proportion of patients with minor cardiac troponin increases (14 to 49 ng/l), the majority of whom do not have MI. Although a heterogeneous group, these patients remain at high risk, and the adjusted mortality rate started to increase at the level of the 99th percentile in healthy controls.
