Despite advanced therapies, maternal mortality in women with pulmonary arterial hypertension (PAH) remains high in pregnancy and is especially high during the post-partum period. However, recent data indicates that morbidity and mortality during pregnancy and after birth have improved for PAH patients. ⋯ Early termination should be discussed. Women who choose to continue with their pregnancy should be treated at specialised pulmonary hypertension centres with experience in managing PAH during and after pregnancy.

Regular patient assessment is essential for the management of chronic diseases, such as pulmonary arterial hypertension (PAH). Comprehensive patient assessment and risk stratification in PAH are important to guide treatment decisions and to monitor disease progression as well as patients' response to treatment. ⋯ The 2015 ESC/ERS PH guidelines recommend regular assessment of multiple variables at an expert centre. The respective merits and limitations of different risk assessment methods in PAH are discussed in this article, as well as some considerations that can be taken into account in the future development of risk assessment tools.

Venous thromboembolism (VTE), consisting of deep vein thrombosis and pulmonary embolism, is a major clinical concern associated with significant morbidity and mortality. The cornerstone of management of VTE is anticoagulation, and traditional anticoagulants include parenteral heparins and oral vitamin K antagonists. Recently, new oral anticoagulant drugs have been developed and licensed, including direct factor Xa inhibitors (e.g. rivaroxaban, apixaban and edoxaban) and thrombin inhibitors (e.g. dabigatran etexilate). This narrative review focusses on the characteristics of these direct anticoagulants and the main results of published clinical studies on their use in the prevention and treatment of VTE.

Pulmonary arterial hypertension (PAH) is a severe and progressive disease, characterised by high pulmonary artery pressure that usually culminates in right heart failure. Recent findings of alterations in the DNA methylation state of superoxide dismutase 2 and granulysin gene loci; histone H1 levels; aberrant expression levels of histone deacetylases and bromodomain-containing protein 4; and dysregulated microRNA networks together suggest the involvement of epigenetics in PAH pathogenesis. ⋯ Moreover, the influence of genetic predisposition and the acquisition of epigenetic alterations in response to environmental cues in PAH progression and establishment has largely been unexplored on a genome-wide scale. In order to gain insights into the molecular mechanisms leading to the development of PAH and to design novel therapeutic strategies, high-throughput approaches have to be adopted to facilitate systematic identification of the disease-specific networks using next-generation sequencing technologies, the application of these technologies in PAH has been relatively trivial to date.
