Which systolic pressure should be used for the management of an aortic aneurysm?

Below 140. Lower is fine, too, as long as you are not feeling lightheaded or dizzy. Keeping the BP low slows the rate of aneurysm expansion. Decreasing the heart rate to <80 is also thought to reduce the shear stress that increases growth rate of aneurysms. Remember, active smoking increases the rate of growth of aneurysms and increases the rupture rate of smaller aneurysms, so quit if you are still smoking!
Normlal BP. Good BP control is always important in health management. Understand however that BP control will not cause AAA to decrease in size. Careful and frequent monitoring of the size of the aneurysm is very much in order.

What is the systolic pressure that should be used for the management of an aortic aneurysm?

Less than 120. I usually recommend beta blockers and aim for systolic less than 120. I also get echocardiogram to rule out bicuspid aortic valve and aortic regurgitation.
Heart rate. I think that as important as blood pressure control is the control of heart rate. I try to keep the heart rate around 60 beats per minute with a beta blocker. Every time your heart beats it's a jolt to the artery. If you slow the heart rate from 80 to 60 bpm, then that is 28, 000 beats a day - 200, 000 beats a week and more than 6 million in a month!
