Study shows evidence that BP should be measured in both arms
A new study has suggested that there is an association between a difference in interarm systolic blood pressure and a significant increased risk for future cardiovascular events, leading researchers to recommend expanded clinical use of interarm blood pressure measurement.
Measuring interarm blood pressure involves taking two readings, one for each arm.
Increased interarm systolic blood pressure differences are defined as 10 mmHg or greater, and while a link between interarm blood pressure and cardiovascular risk was suspected, little data existed to support the hypothesis until now.
The new study, led by Ido Weinberg, MD, Institute for Heart Vascular and Stroke Care, Massachusetts General Hospital, Boston, examined 3,390 participants aged 40 years and older from the Framingham Heart Study.
All subjects were free of cardiovascular disease at baseline, but investigators found that participants with higher interarm systolic blood pressure differences were at a much higher risk for future cardiovascular events than those with less than a 10 mm Hg difference between arms.
Researchers also found that participants with elevated interarm blood pressure difference were older, had a greater prevalence of diabetes mellitus, higher systolic blood pressure, and a higher total cholesterol level.
The study is published in the American Journal of Medicine.
