You may be eligible if
diagnosed hypertension (HT) from clinical records
nocturnal HT (night-time systolic blood pressure (SBP) during sleep ≥120 mmHg) and stage I hypertension (daytime SBP = 135-159mmHg)
You may not be if
patients with atrial fibrillation (many home blood pressure (BP) machines are not validated in these patients and these patients have greater BP variability)
daytime office systolic BP ≥180 mmHg or diastolic BP ≥120 mmHg (regardless of nocturnal BP) because these patients need urgent BP treatment and it is not known if medications given in the evening are equally effective
patients with known obstructive sleep apnoea because the night-time BP of these patients is predominately affected by the sleep apnoea
patients with known stroke, ischemic heart disease, heart failure, kidney failure, peripheral vascular disease and diabetes mellitus because their daytime BP targets will be different
dementia or psychiatric illness that impairs patients' ability to perform home blood pressure monitoring (HBPM) by themselves
patients with end-stage malignancies
nocturnal worker, because they will have a reverse BP pattern to other participants
patients who sleep after 2am or wake up before 4am because these patients will not be asleep during night HBPM
patients receiving ≥3 BP medications at maximal tolerated doses because there is little space for drug titration and these patients may have secondary HT representing another disease spectrum
patients receiving anti-coagulants because ABPM can induce significant bruises (during repeated cuff inflations) in these patients.
