The new definition of HT given by AHA ACC is BP greater than 130 80 mm Hg. Anyone with BP more than 130 80 mm Hg is now considered as having HT. There is lot of evidence to suggest that any BP higher than 130 80 can be detrimental to health. So the gold standard for HT diagnosis is not 140 90 but 130 80. This applies to all age groups and comorbidities. People with BP more than 130 80 should be counselled for lifestyle changes and then drug treatment. So the new cut off between normal and high BP is 130 80 and not 140 90. Beta blockers are now rated as secondary drugs for HT not primary. First line drugs for HT are diuretics CCBs ACEIs and ARBs. Among the diuretics the preferred choice is chlorthalidone not HCTZ or indapamide. The new guidelines will change the way medicine will be practiced from now on. The BP should be 130 80 or lower. New Recommendation.
