AGT and hypertensive disorder: Hypertension is a critical risk factor for stroke, renal failure and cardiovascular disease and has been associated with a range of well recognized complications, including congestive heart failure, left ventricular hypertrophy, and atherosclerosis, and with more subtle structural and functional changes to target organs and tissues occurring as a consequence of enhanced salt sensitivity [2], enhanced angiotensin II sensitivity [3] and structural modifications to the arterial wall [4,5].
