- Background Patients with chronic kidney disease (CKD) have poor outcomes following myocardial infarction (MI). We performed an untargeted examination of 175 biomarkers to identify those with the strongest association with CKD and to examine the association of those biomarkers with long-term outcomes. Methods A total of 175 different biomarkers from MI patients enrolled in the Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) registry were analysed either by a multiple reaction monitoring mass spectrometry assay or by a multiplex assay (proximity extension assay). Random forests statistical models were used to assess the predictor importance of biomarkers, CKD and outcomes. Results A total of 1098 MI patients with a median estimated glomerular filtration rate of 85 mL min(-1)/1.73 m(2)were followed for a median of 3.2 years. The random forests analyses, without and with adjustment for differences in demography, comorbidities and severity of disease, identified six biomarkers (adrenomedullin, TNF receptor-1, adipocyte fatty acid-binding protein-4, TNF-related apoptosis-inducing ligand receptor 2, growth differentiation factor-15 and TNF receptor-2) to be strongly associated with CKD. All six biomarkers were also amongst the 15 strongest predictors for death, and four of them were amongst the strongest predictors of subsequent MI and heart failure hospitalization. Conclusion In patients with MI, a proteomic approach could identify six biomarkers that best predicted CKD. These biomarkers were also amongst the most important predictors of long-term outcomes. Thus, these biomarkers indicate underlying mechanisms that may contribute to the poor prognosis seen in patients with MI and CKD.

- Introduction: Most mental disorders, when examined individually, are associated with an increased risk of cardiometabolic complications. However, these associations might be attributed to a general liability toward psychopathology or confounded by unmeasured familial factors.Objectives: To examine whether the associations between psychiatric diagnoses and increased risk of cardiometabolic complications are attributable to a general liability toward psychopathology, or confounded by unmeasured familial factors.Methods: We conducted a cohort study in Sweden and identified all individuals and their siblings born in Sweden 1955-1962 with follow-up through 2013. After excluding individuals who died or emigrated before 1987, the final sample consisted 672 823 individuals. We extracted ICD-coded diagnoses (recorded 1973-1987) for ten psychiatric conditions and criminal convictions when participants were aged 18-25 years, and ICD-coded diagnoses (recorded 1987-2013) for five cardiometabolic complications (obesity, hypertensive diseases, hyperlipidemia, type 2 diabetes mellitus, and cardiovascular diseases) when the participants were 51-58 years old. Logistic regression models were used to estimate the bivariate associations between psychiatric conditions or criminal convictions and cardiometabolic complications in individuals. A general factor model was used to identify general, internalizing, externalizing, and psychotic factors based on the psychiatric conditions and criminal convictions. We then regressed the cardiometabolic complications on the latent general factor and three uncorrelated specific factors within a structural equation modeling framework in individuals and across sibling pairs.Results: Each psychiatric conditions significantly increased the risk of cardiometabolic complications; however, most of these associations were attributable to the general factor of psychopathology, rather than to specific psychiatric conditions. There were no or only small associations between individuals’ general psychopathology and their siblings’ cardiometabolic complications, suggesting that the associations were not attributable to genetic or environmental confounding factors shared within families. The same pattern was evident for the specific internalizing and psychotic factors.Conclusions: Individuals with mental disorders in early life had an increased long term risk of cardiometabolic complications, which appeared attributable to a general liability toward psychopathology. Sibling analyses suggested that the elevated risk could not beattributed to confounds shared within families. This highlights the importance of transdiagnostic and lifestyle based interventions to reduce the risk of cardiometabolic complications, particularly in patients with several mental disorders.

- Introduction: Smoking is a major risk factor for both chronic obstructive pulmonary disease (COPD) and myocardial infarction (MI). Systemic inflammation also contributes to both diseases and has been suggested as a potential target for intervention. Prevalence of COPD in those with a significant smoking history hospitalised for MI has not been well-characterised. We sought to obtain an accurate estimate of COPD burden in this group and characterise the population.Methods: Two consecutive cohorts of patients hospitalised for MI with a smoking history of ≥10 pack-years were recruited in Sweden and the United Kingdom (UK). Baseline characteristics were recorded, including treatment with inhaled corticosteroids (ICS) and eosinophil count in blood. Microspirometry was performed using the Vitalograph COPD-6 device and symptom burden assessed using the COPD Assessment Test (CAT). The primary outcome was the prevalence of a preliminary diagnosis of clinically-significant COPD, here defined as a ratio of forced expiratory volume in 1 and 6 seconds (FEV1/FEV6) <0.7 and with FEV1 <80% of predicted value.Results: In the UK cohort, 216 participants with MI (26% female, median age 60 (IQR 53–67) years, smoking history 32 (23–45) pack-years) were recruited. The proportion with any COPD was 36%. Clinically-significant COPD was found in 30 participants (13.9%, 95% CI 9.5–19.2). Of these, 43% had a prior COPD diagnosis, 20% had an eosinophil count ≥300 cells/mm3, mean CAT score was 14.4 ± 9.3), 80% had high symptom burden (CAT score >10) and 23% were receiving ICS. The Swedish cohort included 302 participants with MI (24% female, median age 68 (IQR 61–76) years, 26 (15–38) pack years), and clinically-significant COPD was found in 52 (17.2%; 12.9–21.5). In these 52 participants, 17% had a prior COPD diagnosis, 20% had an eosinophil count ≥300 cells/mm3, mean CAT score was 12.9 ± 7.2, 63% had CAT score ≥10 and 15% had treatment with ICS.Conclusions: The prevalence of preliminary diagnosis of clinically-significant COPD in patients with a ≥10 pack-year smoking history hospitalised for MI is similar between two European cohorts and under-recognised. Further work is warranted to determine whether identification and treatment of COPD improves clinical outcomes following MI.
