Research recommendations
The Guideline Development Group has made the following recommendations for research,
based on its review of evidence, to improve NICE guidance and patient care in the future.
4.1 Out-of-office monitoring
In adults with primary hypertension, does the use of out-of-office monitoring (HBPM or ABPM)
improve response to treatment?
Why this is important
There is likely to be increasing use of HBPM and for the diagnosis of hypertension as a
consequence of this guideline update. There are, however, very few data regarding the utility of
HBPM or ABPM as means of monitoring blood pressure control or as indicators of clinical
outcome in treated hypertension, compared with clinic blood pressure monitoring. Studies should
incorporate HBPM and/or ABPM to monitor blood pressure responses to treatment and their
usefulness as indicators of clinical outcomes.
4.2 Intervention thresholds for people aged under 40 with
hypertension
In people aged under 40 years with hypertension, what are the appropriate thresholds for
intervention?
Why this is important
There is uncertainty about how to assess the impact of blood pressure treatment in people aged
under 40 years with stage 1 hypertension and no overt target organ damage or cardiovascular
disease (CVD). In particular, it is not known whether those with untreated hypertension are more
likely to develop target organ damage and, if so, whether such damage is reversible. Target
organ damage and CVD as surrogate or intermediate disease markers are the only indicators
that are likely to be feasible in younger people because traditional clinical outcomes are unlikely
to occur in sufficient numbers over the timescale of a typical clinical trial. The data will be
