- Scarce and conflicting evidence exists on whether clopidogrel is effective and whether dual antiplatelet treatment (DAPT) is safe in patients with acute coronary syndrome and chronic kidney disease (CKD). To study this, we performed an observational, prospective, multicenter cohort study of 36,001 patients of the SWEDEHEART registry. The exposure was DAPT prolonged after 3 months versus DAPT stopped at 3 months in consecutive patients with acute coronary syndrome and known serum creatinine. DAPT duration with clopidogrel and aspirin was assessed by dispensed tablets. CKD stages were classified according to estimated glomerular filtration rate (eGFR). Study outcomes were 1) the composite of death, myocardial infarction, or ischemic stroke; 2) bleeding; or 3) the aggregate of these two outcomes within day 111 and 365 from discharge. A longer DAPT duration, as compared with 3-month DAPT, was associated with lower hazard ratios for outcome one in each CKD stratum (eGFR over 60, adjusted hazard ratio [95% confidence interval] 0.76 [0.67-0.85]; eGFR 60 and less, 0.84 [0.73-0.96], of which eGFR between 45 and 60, 0.85 [0.70-1.05], eGFR between 30 and 45, 0.78 [0.62-0.97]; eGFR 30 and less ml/min/1.73 m(2), 0.93 [0.70-1.24]. Bleeding (outcome 2) was in general more common in the longer DAPT group of each aforementioned CKD stratum. Aggregated outcome analysis (outcome 3) similarly favored longer DAPT in each stratum. There was no interaction between DAPT duration and CKD strata for any of the study outcomes. Thus, a prolonged as compared with three-month DAPT was similarly associated with a lower risk of death, stroke, or reinfarction regardless of underlying CKD.

- Aims/hypothesis: In a population-based cohort of elderly men with well-defined phenotypes and biochemical markers related to type 2 diabetes mellitus, we analysed two single nucleotide polymorphisms (SNPs), rs7903146 and rs12255372, in the transcription factor 7-like 2 gene (TCF7L2), which are associated with an increased risk of type 2 diabetes mellitus. Materials and methods: The 1,142 subjects were from the population-based Uppsala Longitudinal Study of Adult Men cohort study (see http://www.pubcare.uu.se/ULSAM/ , last accessed in May 2007). Insulin sensitivity was assessed using a euglycaemic-hyperinsulinaemic clamp; fasting intact and 32-33 split proinsulin, immunoreactive insulin and specific insulin were measured in plasma samples. The SNPs rs7903146 and rs12255372 were genotyped using a fluorescent homogeneous single base extension assay. The SNP genotypes were analysed against diabetes prevalence at age 70 using logistic regression and against quantitative biochemical measures using linear regression analysis. Results: We replicated the association with type 2 diabetes mellitus for both SNPs in this cohort of elderly males. The highest significant odds ratio (2.15, 95% CI 1.20-3.85) was found for SNP rs7903146. The odds ratio for SNP rs12255372 was 1.69 (95% CI 1.20-2.39). Both TCF7L2 SNPs were found to be significantly associated with plasma proinsulin when adjusting for insulin sensitivity, both in the whole cohort and when the diabetic subjects were excluded. Analysis for fasting plasma insulin or insulin sensitivity did not give significant results. Conclusions/interpretation: The association between the risk alleles of the two SNPs studied and levels of proinsulin in plasma, identified when adjusting for insulin sensitivity using euglycaemic-hyperinsulinaemic clamp measurements in this study, is an important novel finding.

- Background: There are conflicting data on outcomes in patients with atrial fibrillation treated with non-vitamin K oral anticoagulants across varying body mass index (BMI). We investigated cardiovascular and bleeding risk in patients with atrial fibrillation with varying BMI.Methods and Results: Observational cohort study from the Swedish oral anticoagulation registry between August 2, 2011, and December 31, 2018. Primary outcomes were mortality, ischemic stroke/systemic embolism, and major bleeding. Baseline BMI (kg/m(2)) was analyzed continuously and categorized: underweight (<18.5 kg/m(2)), normal weight (18.5 to <25 kg/m(2)), preobesity (25 to <30 kg/m(2)), and obesity class I to III (30 to <35, 35 to <40, and >= 40 kg/m(2)). Adjusted Cox models and nonlinear relationships of BMI were modeled using restricted cubic splines. Non-vitamin K oral anticoagulant-treated patients with atrial fibrillation were included (n=26 047). At baseline, 602 (2.3%) were underweight, 9101 (34.9%) were normal weight, 9970 (38.3%) were preobese, 4280 (16.4%) were obese class I, 1486 (5.7%) were obese class II, and 608 (2.3%) were obese class III. Underweight and obesity class III were in adjusted continuous analysis associated with increased mortality and major bleeding, with lowest risk observed among preobese patients with BMI 28.2 and 26.2 kg/m(2), respectively. In adjusted categorical analysis, underweight was associated with increased mortality (hazard ratio [HR], 1.77 [95% CI, 1.57-1.99]) and nonsignificant higher risk of major bleeding (HR, 1.23 [95% CI, 0.95-1.58]). Similarly, obesity class III was associated with increased mortality (HR, 1.67 [95% CI, 1.40-1.99]) and major bleeding (HR, 1.68 [95% CI, 1.29-2.17]). No significant association was observed between higher BMI and ischemic stroke/systemic embolism.Conclusions: In non-vitamin K oral anticoagulant-treated patients with atrial fibrillation, there appears to be a U-shaped relationship between BMI and mortality and major bleeding.

- Context: Cross-sectional and nested case-control studies indicate a relationship between adiponectin, obesity, and coronary heart disease (CHD). Objective: Our objective was to investigate whether adiponectin could predict CHD in a population-based cohort of elderly men. Design and Setting: From 1991-1995 a baseline investigation was carried out in 832 healthy men aged 70 yr in the Uppsala Longitudinal Study of Adult Men (ULSAM study). They were followed up to 10.4 yr using Swedish national registry data. The baseline investigation included anthropometry, blood pressure, smoking, serum lipids, a euglycemic insulin clamp, and fasting serum adiponectin. Main Outcome Measures: Main outcome measures were defined as death or first-time hospitalization for CHD (n = 116), recorded in the Cause of Death Registry or in the Hospital-Discharge Registry of the National Board of Health and Welfare, Sweden. Associations were analyzed using Cox's proportional hazards regression, presented as hazard ratios (HR) with 95% confidence intervals (CI) for 1 SD increase in the predictor variable. Results: In a multivariable analysis including total cholesterol (HR, 1.24; CI, 1.02-1.50), high-density lipoprotein cholesterol (HR, 0.72; CI, 0.58-0.89), smoking (HR, 1.39; CI, 0.91-2.14), and systolic blood pressure (HR, 1.26; CI, 1.05-1.52), serum adiponectin was associated with lower risk for CHD (HR, 0.81; CI, 0.66-0.99). The association was independent of BMI and remained significant after adjustment for insulin sensitivity index. Conclusions: In this population-based cohort of healthy men, elevated serum levels of adiponectin were associated with a lower risk for CHD. Importantly, the association between adiponectin and CHD was independent of other well-known risk factors.

Tidskriftsartikel (refereegranskat)abstract
- Myocardial infarction is a leading cause of death globally but is notoriously difficult to predict. We aimed to identify biomarkers of an imminent first myocardial infarction and design relevant prediction models. Here, we constructed a new case–cohort consortium of 2,018 persons without prior cardiovascular disease from six European cohorts, among whom 420 developed a first myocardial infarction within 6 months after the baseline blood draw. We analyzed 817 proteins and 1,025 metabolites in biobanked blood and 16 clinical variables. Forty-eight proteins, 43 metabolites, age, sex and systolic blood pressure were associated with the risk of an imminent first myocardial infarction. Brain natriuretic peptide was most consistently associated with the risk of imminent myocardial infarction. Using clinically readily available variables, we devised a prediction model for an imminent first myocardial infarction for clinical use in the general population, with good discriminatory performance and potential for motivating primary prevention efforts.

- OBJECTIVES The aim of this study was to describe current practice regarding completeness of revascularization in patients with multivessel disease undergoing percutaneous coronary intervention (PCI) and to investigate the association of incomplete revascularization (IR) with death, repeat revascularization, and myocardial infarction (MI) in a large nationwide registry. BACKGROUND The benefits of multivessel PCI are controversial. METHODS Between 2006 and 2010 we identified 23,342 patients with multivessel disease in the SCAAR (Swedish Coronary Angiography and Angioplasty Registry) and merged data with official Swedish health data registries. IR was defined as any nontreated significant (60%) stenosis in a coronary artery supplying > 10% of the myocardium. RESULTS Patients with IR (n = 15,165) were older, had more extensive coronary disease, and more often had ST-segment elevation MI at presentation than those with complete revascularization (CR) (n = 8,177). All-cause 1-year mortality, MI, and repeat revascularization were higher in IR than CR: 7.1% versus 3.8%, 10.4% versus 6.0%, and 20.5% versus 8.5%, respectively. Propensity score methodology was used in the adjusted analyses. Adjusted hazard ratio (HR) for the composite of death, MI, or repeat revascularization at 1 year was higher in IR than CR: 2.12 (95% confidence interval [CI]: 1.98 to 2.28; p < 0.0001). Adjusted HR for death and the combination of death/MI were 1.29 (95% CI: 1.12 to 1.49; p = 0.0005) and 1.42 (95% CI: 1.30 to 1.56; p < 0.0001), respectively. CONCLUSIONS Incomplete revascularization at the time of hospital discharge in patients with multivessel disease undergoing PCI is associated with a high risk of recurrent 1-year adverse cardiac events.

- The activity index of stearoyl-CoA desaturase (SCD), a key enzyme in lipogenesis, was associated with increased risk of fracture in a longitudinal population-based cohort of men. This indicates that elevated levels of endogenous lipogenesis increase the risk of fracture and suggest a role for saturated fat in the pathogenesis of osteoporosis. INTRODUCTION: Osteoblasts and marrow adipocytes are derived from a common mesenchymal progenitor, and experimental studies have indicated that increased adipogenesis can occur at the expense of osteoblasts, leading to bone loss. Stearoyl-CoA desaturase (SCD) converts saturated to monounsaturated fatty acids and is a key enzyme in lipogenesis. METHODS: Analysis was performed in a population-based, longitudinal cohort study of men (n = 2009). A product-to-precursor index (palmitoleic acid/palmitic acid) was used to estimate SCD activity in fasting serum analyzed in samples obtained at enrollment at age 50 years. Fractures were documented in 422 men during 35 years of follow-up. Cox regression analysis was used to determine the risk of fracture according to SCD activity index. RESULTS: The risk of fracture was highest among men with the highest levels of SCD activity index. Multivariable analysis of the risk of fracture in the highest quintile as compared to the lowest one showed that the rate ratio was 1.71 (95% CI 1.26-2.33) for any fracture, with an estimated population attributable risk of 15%. The risk was further increased within the highest quintile. CONCLUSIONS: Our results indicate that elevated levels of endogenous lipogenesis increase the risk of fracture and suggest a role for saturated fat in the pathogenesis of osteoporosis.
