Hypertension -- Unique Phenotypes and Antihypertensive Treatment

"At present approximately 50 million Americans live with blood pressure (BP) levels elevated enough to be considered 'hypertensive.' According to most of the current national guidelines, this means sitting systolic/diastolic blood pressure (SBP/DBP) values > 140/90 mm Hg for nondiabetic individuals and 130/80 mm Hg for those with diabetes.[1-3] Although the proportion of patients who achieve BP control has increased in the past quarter century, control is still low. For example, in the United States it is still only 34%,[4] and control rates are still lower in many other industrialized countries."

Was there a difference in the criteria for diagnosing Hypertension in Diabetics even earlier?
