The 2020 International Society of Hypertension global hypertension practice guidelines - key messages and clinical considerations

      Abstract

      The International Society of Hypertension (ISH) has recently developed practice guidelines for the management of hypertension in adults aged ≥18 years. Conceptually, the 2020 ISH Guidelines are closer to the 2018 ESC/ESH Guidelines rather than to the 2017 ACC/AHA Guidelines. The ISH Guidelines have two distinctive features when compared with the 2018 European Society of Cardiology/European Society of Hypertension (ESC/ESH) Guidelines and the 2017 American College of Cardiology/American Heart Association (ACC/AHA) Guidelines. First, they are written in a concise and easy-to-read style; second, they focuses on practical issues related to the management of hypertension in ‘high-income’ as well as in ‘low-income’ countries, where there is limited access to resources for the diagnosis and treatment of hypertension. In our opinion, the 2020 ISH Guidelines share with the 2018 ESC/ESH Guidelines an important limitation which may impair the retention of these key aspects of Guidelines by physicians, with consequent difficult adoption in clinical practice. It consists in the definition of several blood pressure targets in relation to age, target organ damage and concomitant disease. We believe that results of randomized clinical trials and meta-analysis do not support the recommendation of differential BP targets, as well as of rigid ‘safety boundaries’. This review critically examines similarities and differences across the three major Hypertension Guidelines, which include the definition of hypertension, drug treatment, and blood pressure targets, with emphasis on key messages relevant for clinical practice.
