Comparative Study
Sensitive cardiac troponin in the diagnosis and risk stratification of acute heart failure.
The aim of our study was to investigate the diagnostic and prognostic value of a sensitive cardiac troponin I (s-cTnI) assay in patients with acute heart failure (AHF). ⋯ Sensitive cardiac troponin I is a strong predictor of short- and long-term prognosis in AHF that helps to reclassify patients in terms of mortality risk. Detectable levels of s-cTnI, even within the normal range, are independently associated with mortality.

To investigate whether Caucasian patients with polymyositis (PM) or dermatomyositis (DM) and interstitial lung disease (ILD) have elevated serum levels of KL-6 compared with patients without ILD and whether KL-6 could be used as a marker for ILD activity and treatment efficacy of ILD in PM/DM. ⋯ The level of serum KL-6 may serve as measure of ILD in patients with PM/DM and is a promising biomarker for use in clinical practice to assess clinical response to treatment.

Venous thromboembolism (including deep vein thrombosis and pulmonary embolism) and atrial fibrillation are common conditions in Western countries. The mainstay of treatment and prevention for these diseases is fast-acting anticoagulant drugs such as heparins and vitamin K antagonists. ⋯ Recently, new antithrombotic drugs that act directly by inhibiting activated coagulation factors such as factor X or thrombin have been developed and investigated in phase III clinical trials. The aim of this article is to review: (i) the need to develop new drugs; (ii) their efficacy/safety as demonstrated in clinical trials; (iii) the need for laboratory monitoring and (iv) the direction towards the use of these new drugs in the real-life clinical situation.

Review
Can persistent organic pollutants and plastic-associated chemicals cause cardiovascular disease?
During the last decade, associations between persistent organic pollutants (POPs), such as polychlorinated biphenyls, dioxins and pesticides, and cardiovascular (CV) risk factors and overt CV disease (CVD) have been reported in humans. Recently, associations between plastic-associated chemicals (PACs), such as bisphenol A and phthalates, and CVD have also begun to emerge. Several approaches to evaluating such associations have been used: accidents with a high level of exposure, occupational exposure studies, geographical studies of subjects living near a contaminated area and traditional case-control or cohort studies with measurements of circulating levels of different environmental contaminants in the general population. ⋯ The evidence regarding associations between exposure to POPs and other CV risk factors, such as hypertension, obesity and lipids, is less strong and is mainly based on cross-sectional data. Associations between overt CVD and POPs have been reported using all the above approaches, but prospective data from population-based studies are still lacking to provide firm evidence of an important and independent role of POP exposure in the pathogenesis of CVD. Nevertheless, taken together, current evidence suggests that further longitudinal and experimental studies should be conducted to investigate the effect of exposure to both POPs and PACs, such as bisphenol A and phthalates.
