Study of  data from 22,672 patients with stable coronary artery disease enrolled  in the CLARIFY registry (including patients from 45 countries) and treated for hypertension showed that n on-fatal and fatal outcomes  decreased as blood pressure was reduced to a  120–139 mm Hg systolic or a 70–79 mm Hg diastolic  range over 5 years of treatment. Blood pressure  reductions to less than 120/70 mm Hg, however, were  accompanied by a marked increase of cardiovascular risk  that involved cause-specific events such as myocardial  infarction and heart failure, only sparing stroke, whose  risk remained similar to that seen at the higher blood  pressure values.

This finding warns against an extensive  extrapolation of the results of the SPRINT trial (ie, that  an approach of the lower the achieved blood pressure,  the better, should be pursued in all individuals at high  cardiovascular risk).…
