"Hypertension SBP ≥ 180 DBP ≥ 110  (& asymptomatic) urgency not so urgent"

I have seen many patients with high blood pressure and no symptoms (headache, epistaxis, faintness, psychomotor agitation, chest pain, dyspnoea, and neurologic deficit) who, with treatment, have lived long healthy lives. I have learnt not to panic and start gradual treatment. When I have “panicked” and started high dose medication I have sometimes caused harm through hypotension. 

This study had over 2 million office visits and 4.6% met the definition of hypertensive urgency (SBP ≥ 180 DBP ≥ 110 & asymptomatic).1 They compared a matched sample of 426 patients sent to hospital with 852 who were not. At 7, 30 & 180 days there was no difference in cardiovascular events. Patients sent home had more uncontrolled hypertension at 1 month but not 6 months. Patients sent home had fewer admissions at 7 and 30 days. Visits to emergency departments were associated with more hospitalisations.

Iona Heath from the UK has a great editorial on the topic.2
