- drug therapy should be started in all patients with sustained systolic
blood pressures >= 160 mmHg despite non-pharmacologic measures (1,2)
- isolated hypertension (>=160/<90 mmHg) occurs in more than 50% of
patients over 60 years old. Isolated systolic hypertension and wide pulse
pressure in elderly people increase the risk of mortality and morbidity (2).
Treatment leads to a reduction in risk (2,3,4,5)
- in the SHEP trial, treatment of isolated systolic hypertension with
chlorthalidone stepped-care therapy for 4.5 years was associated with
longer life expectancy at 22 years of follow-up (6)
- there is no firm evidence to guide the management of borderline isolated
hypertension (systolic blood pressure 140-159mmHg and diastolic blood pressures
- NICE state that patients with isolated systolic hypertension (systolic BP
160 mmHg or more) should be offered the same treatment as patients with both
raised systolic and diastolic blood pressure (1)
- the guidance also notes that patients with isolated systolic hypertension
received similar benefits from treatment to other patients with raised
