Consensus documents and challenges in hypertension research.

DOI:10.1097/HJH.0000000000001040 G uidelines and consensus documents are important instruments by which scientific and healthcare societies or organizations translate the most recent findings of medical research to medical practice, and the Journal of Hypertension is delighted to publish those issued by its endorsing societies and their working groups. Guidelines and consensus documents are also valuable, not only for providing practical recommendations in the areas where evidence and therefore consensus are available, but for identifying areas that are still disputed and require further in-depth investigation. In this way, consensus documents and original articles work together in a scientific journal such as ours in clarifying dissention, stimulating investigation and deepening knowledge. The present issue of the Journal publishes 21 original articles, two consensus documents and one review article. The first consensus document has been produced by the European Society of Hypertension Working Group on Blood Pressure Monitoring and focuses on methodology and technology for peripheral and central blood pressure and blood pressure variability measurement (Stergiou et al., pp. 1665–1677), discussing key research and practical issues in regard to peripheral office, home and ambulatory measurements; peripheral blood pressure variability and central blood pressure measurement. The document wisely acknowledges that its objectives are not only to review current achievements, but particularly that of presenting open research questions and suggesting future research and developments for investigators as well as for manufacturers. The complementary nature of consensus documents and original research is illustrated by the publication in this same issue of the journal of an original article (Lindroos et al., pp. 1730–1737) comparing night-time ambulatory blood pressure monitoring with new techniques for night-time recording of blood pressure at home, and investigating their respective associations with hypertension-associated organ damage. The other consensus document published in the current issue of the Journal is a joint statement of the European Society of Hypertension and the European Association for the Study of Obesity, which calls attention on the quite neglected topic of the relationships between obesity and heart failure (Jordan et al., pp. 1678–1688). The overview of the area the document provides identifies open questions that ought to be addressed and strongly encourages prospective trials to properly answer these questions. The review article following the two consensus documents introduces a series of original articles focusing on
