Although long in the tooth atherosclerotic hypertensive individuals often maintain atherosclerotic renal artery bug, their hypertension is almost always STEPS IN M AKING THE DIAGNOSIS essential hypertension, not RVH T. O n stability, the ubiquity of OF RENOVASCULAR HYPERTENSION RVH T in the mongrel hypertensive population is to all intents no m ore than 2% to 3%.
