Role of hypertension in the progression of chronic renal disease
Ponce School of Medicine, Ponce, Puerto Rico 00732
Hypertension leads to renal disease through a series of mechanisms that seem to be exaggerated in African-Americans, who have a higher prevalence of both hypertension and end-stage renal disease than whites. Renal disease itself leads to hypertension, which in turn can contribute to progression of renal disease. Although there are numerous mechanisms involved in the process of renal disease progression, the reninangiotensin system plays a major role as determined by the beneficial response to angiotensin I-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (AT II blockers) of reduced rate of progression in a variety of clinical and experimental renal diseases. Macromolecular trafficking across the glomerulus leading to proteinuria plays a significant role in progression of chronic renal disease. Reversal of this abnormality and reduced stress on capillary walls may be the major mechanisms of beneficial action of ACEIs and AT II blockers in halting renal disease progression.
Keywords: ACE inhibitors; angiotensin II; chronic renal disease; hypertension; reninangiotensin system
