Lowering one’s blood pressure to reach ‘ normal’ values is known to have little clinical benefit according to Cochrane analysis.
 
According to Cochrane Review’s systematic analysis  of available  evidence, researchers found that the use of  anti -hypertensive drugs to bring down the  blood pressure below  140/90 mm Hg did not reduce associated  death rates or the morbidity linked to  high BP.

A number of publications suggest that “lower is better” and recommend aiming for lower BP targets. The present study does not endorse this view.

The review included seven trials involving 22,089 people. It showed that there was no difference, between the standard group (aiming for a BP of  140/90Hg) and the second group (aiming for 135/85Hg), in terms of death rates or associated morbidities like heart attacks, strokes and  heart  or kidney failure.
 
Says Jose Arguedas, lead researcher of the Faculty of Medicine at the University of Costa Rica, “At present there is no evidence from randomized trials to support aiming for a blood pressure target lower than 140/90, in the general population of patients with elevated blood pressure,”
 
“Our research included patients with diabetes or chronic renal disease, and the evidence was slightly less robust for those subgroups of patients. We intend to carry out separate systematic reviews for those subgroups, especially because guidelines recommend even lower blood pressure targets for them”, states Arguedas.
 
Perhaps the trick to increase one’s life span is to keep lifestyle diseases, like diabetes, at bay. This can be realized by   following the ‘take it easy’ policy to reduce stress and by maintaining a healthy lifestyle regime. Life then becomes more pleasurable and worth every living  minute!
