title: Hypertension and the kidney: determinants of the response to antihypertensive therapy and their implications.
abstract: Medicine has long recognized an association between hypertension and the kidney. The kidney may be a culprit or a victim in the process. As a culprit, the kidney may be responsible for the pathogenesis of hypertension in many patients, and in virtually all patients the renal response to antihypertensive therapy is a major determinant of its success or failure. In some patients, hypertension can lead to renal injury and even end-stage renal disease. Indeed, 25% of patients entering dialysis or transplant programs in the United States today have hypertension as the primary or sole mechanism, and another 25% have the complex combination of diabetes and hypertension as the cause. Antihypertensive therapy appears to be successful in preventing or arresting the renal response in accelerated hypertension, regardless of the treatment used to reduce blood pressure. However, treatment appears to be less successful in preventing the progression of moderate hypertension to end-stage renal disease. Substantial evidence suggests that angiotensin-converting enzyme inhibition and calcium channel blockade may prevent this progression when other antihypertensive therapy does not. The renal response to an angiotensin-converting enzyme inhibitor or a calcium channel-blocking agent appears to be determined by the pathogenetic features of the hypertension, and this may be an important determinant of the efficacy of the agents selected. Although still indistinct, the guidelines favoring selection of a specific antihypertensive agent are gradually emerging.
