A ‘J-curve’ association between blood pressure (BP) and stroke has been previously reported, whereby highest and the lowest BPs were associated with increased risks of recurrent stroke among patients with recent ischaemic stroke. Clearly, such a finding has management implications. In an upcoming issue of JNNP, the PROGRESS Collaborative Group dismiss this myth. Namely, large reductions of BP (> 20 mmHg) WERE NOT associated with an increased risk of any types of stroke, with the annual incidence hovering between 2-3%.
So I guess, the answer may well be to treat hypertension aggressively, but not to the point of dizziness.
