BP mismatch between arms signals risk
March 22, 2012
Patients with hypertension who have double-digit differences in blood pressure between arms appear to be at risk for cardiovascular events and premature death, a small study showed.
The risk of all-cause death over a follow-up of about 10 years was more than three-fold higher for patients with interarm systolic blood pressure differences of 10 mm Hg (HR 3.6, 95% CI 2.0 to 6.5) and 15 mm Hg (HR 3.1, 95% CI 1.6 to 6.0), according to Christopher Clark, PhD, of the University of Exeter in England, and colleagues.
Similar relationships were seen for cardiovascular death and combined cardiovascular and cerebrovascular events, the researchers reported online in BMJ.
