Intensive blood pressure control 'favours' cerebral blood flow

Researchers have analysed an imaging sub-study of the landmark SPRINT trial

Intensive blood pressure lowering in elderly patients appears to increase, rather than decrease, cerebral perfusion compared with standard treatment, a study shows.

US clinicians say this modest, yet significant, effect on cerebral blood flow was most pronounced among those with a history of cardiovascular disease.

Results from their sub-study of 547 participants in the SPRINT (Systolic Blood Pressure Intervention Trial)  suggests that, contrary to widely-held
