2020 International Society of Hypertension Global Hypertension Practice Guidelines

To align with its mission to reduce the global burden of raised blood pressure (BP), the International Society of Hypertension (ISH) has developed worldwide practice guidelines for the management of hypertension in adults, aged 18 years and older. The ISH Guidelines Committee extracted evidence-based content presented in recently published extensively reviewed guidelines and tailored and standards of care in a practical format that is easy-to-use particularly in low, but also in high resource settings – by clinicians, but also nurses and community health workers, as appropriate. Although distinction between low and high resource settings often refers to high (HIC) and low- and middle-income countries (LMIC), it is well established that in HIC there are areas with low resource settings, and vice versa. Herein optimal care refers to evidence-based standard of care articulated in recent guidelines1,2 and summarized here, whereas standards recognize that standards would not always be possible. Hence essential standards refer to minimum standards of care. To allow specification of essential standards of care for low resource settings, the Committee was often confronted with the limitation or absence in clinical evidence, and thus applied expert opinion.
