“…There is evidence that, in patients receiving antihypertensive treatment, cardiovascular risk is determined more strongly by the blood pressure achieved during treatment than by the initial blood pressure. 6,8 Thus, in the case-control study described above, 6 the risk of stroke was more than halved in patients in whom antihypertensive treatment resulted in a systolic blood pressure of less than 140 mm Hg, compared with those in whom systolic blood pressure remained above 160 mm Hg; by contrast, there was no significant association between baseline blood pressure and the risk of stroke in treated patients. Similarly, in a study of 3783 patients attending the Glasgow Blood Pressure Clinic, the lowest mortality rates in patients of all ages were seen in those in whom the greatest reductions in blood pressure were achieved ( Figure 2).…”
