A polymorphism in the angiotensin-converting-enzyme gene (ACE I/D) has been associated with abdominal aortic aneurysm and a link between aortic aneurysm and aortic stiffness has been suggested.
Influence of angiotensin-converting enzyme and angiotensin II type 1 receptor gene polymorphisms on aortic stiffness in normotensive and hypertensive patients.
Since we have recently shown that in hypertensive individuals the A1166C polymorphism of the angiotensin II type 1 receptor (AT1-R) is an independent determinant of aortic stiffness, we designed the present study to assess the influence of this polymorphism on the changes of aortic stiffness after chronic treatment with the angiotensin-converting enzyme inhibitor perindopril and the calcium channel blocker nitrendipine.
