A national study found that the treating people appropriately for high blood pressure reduced their entire mortality by 20%. Treating people adequately for hypertension has been complex because it is estimated that 50% of hypertensives don't know they've high blood pressure, 50% of of those who do know are inadequately treated by MD, and 50% are appropriately treated fail to follow this treatement.
