The American College of Cardiology/American Heart Association released guidelines for the prevention, detection, evaluation, and management of high blood pressure (BP) in adults in 2017. In 2018, the European Society of Cardiology (ESC)/European Society of Hypertension (ESH) published new guidelines for the management of arterial hypertension. Despite the many similarities between these two guidelines, there are also major differences in the guidelines in terms of diagnosis and treatment of hypertension. A working group of the Hong Kong College of Physicians (HKCP) convened and conducted a focused discussion on important issues of public interest, including classification of BP, BP measurement, thresholds for initiation of antihypertensive medications, BP treatment targets, and treatment strategies. The HKCP concurs with the 2018 ESC/ESH guideline on BP classification, which defines hypertension as office systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg. The HKCP also acknowledges the growing evidence of home BP monitoring and ambulatory BP monitoring in the diagnosis and monitoring of hypertension and endorses the wider use of both methods. The HKCP also supports the direction of a risk-based approach for initiation of antihypertensive medications and the specification of a treatment target range for both systolic and diastolic BP with consideration of different age-groups and specific disease subgroups. Non-pharmacological interventions are crucial, both at the societal and individual patient levels. The recent guideline publications provide good opportunities to increase public awareness of hypertension and encourage lifestyle modifications among the local population.
