What would be the reason for differing blood pressure in arms? 120/60 in left, 140/65 in right.

Ive already have 2 Echocardiograms to rule out Coarction of the Aorta, as well as two EKG's. Also had 1 CT scan to check for kidney problems, Bun/Creatine ration is fine. Was diagnosed with hypertension at 22 years old "Now 23" and have been taking Benicar HCTZ and average bp is 132/75

Although I am still worried about this difference between my two arms? My right-arm is usually higher, although sometimes the pressures are very much the same? In other words the difference isn't consistent, but I notice it and it frightens me.

Thank you

It is quite common to have the blood pressure be somewhat different in the two arms. Usually the blood pressure is higher in the right arm, and that is due to the way the arteries come off of the aorta. A modest different in blood pressure between the two arms is not a cause for concern. It would appear that your blood pressure is under reasonable control with medication. It's also a good idea to limit salt intake.
