2020 International Society of Hypertension Global Hypertension Practice Guidelines

Context and Purpose of This Guideline
\nStatement of Remit
\nTo align with its mission to reduce the global burden of raised
\nblood pressure (BP), the International Society of Hypertension
\n(ISH) has developed worldwide practice guidelines for the
\nmanagement of hypertension in adults, aged 18 years and
\nolder.
\nThe ISH Guidelines Committee extracted evidence-based
\ncontent presented in recently published extensively reviewed
\nguidelines and tailored and standards
\nof care in a practical format that is easy-to-use particularly
\nin low, but also in high resource settings – by clinicians, but
\nalso nurses and community health workers, as appropriate.
\nAlthough distinction between low and high resource settings
\noften refers to high (HIC) and low- and middle-income countries (LMIC), it is well established that in HIC there are areas
\nwith low resource settings, and vice versa.
\nHerein optimal care refers to evidence-based standard of
\ncare articulated in recent guidelines1,2 and summarized here,
\nwhereas standards recognize that
\nstandards 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,
\nthe Committee was often confronted with the limitation or
\nabsence in clinical evidence, and thus applied expert opinion
