Two months ago, I pointed a new study that demonstrated at pre-hypertension, that no man's land between normal blood pressure & hypertension, was associated with an increase risk of stroke. Well, in a meta-analysis published online this week prior to print in February 2012, the authors proved that treating patients w/pre-hypertension lowered their risk of stroke.
As with any other therapy, there was a downside to these double-edged medications. High potassium, kidney failure, excessively low blood pressure, and water retention were all identified as complications & side effects of the medications. When you consider that over 53 million adults in America alone have pre-hypertension, even the small risk of side effect implies affecting a not inconsequential number of patients.
I don't know about you, but aside from kidney failure, I'd rather deal w/hyperkalemia, hypotension, and edema than the residual effects of a stroke.
