According to the BMJ, hypertension (HTN) in Caucasians is high renin (type 1) HTN and responds best to treatment with ACEi and beta-blockers (AB drugs).HTN in young black people is low renin (type 2) HTN and responds better to calcium channel blockers and diuretics (CD drugs).
Morris Brown writes that "as for diabetes, hypertension can usefully be considered as of type 1 or type 2, each with its own preferred treatment."
AB = ACEi, BB for type 1 HTN
CD = CCB, Diuretics for type 2 HTN
This is the proposed ABCD of HTN treatment.
A study published in the Jan 2008 edition of Archives of Internal Medicine "failed to provide support for the selection of alpha-blockers, ACEi, or CCB over thiazide-type diuretics to prevent cardiovascular problems in patients with metabolic syndrome."
