The majority of adults in the U.S. visit the doctor at least once a year–getting check-ups and their blood pressure taken. Next time, ask your doctor to check blood pressure in both arms because it could show if you’re at a higher risk for a stroke.
Check Blood Pressure in Both Arms
Getting your blood pressure checked at the doctor’s is routine. Blood pressure lets the doctor see a glimpse into your heart health and see if actions need to be taken.
The next time you’re there you may want to ask your doctor to measure blood pressure in both arms. Generally, they should be the same, but if they’re not that could mean trouble.
A group of British researchers reviewed the results of 20 studies where blood pressure was taken in both arms. Patients that had a difference of 15 points between each arm were two times more likely to have peripheral artery disease (PAD).
This disease means that there are clogged arteries in the legs, arms, or other non-heart body parts–usually caused by cholesterol. It affects 12 million Americans a year–more than stroke and heart disease combined– and can be deadly.
The study was published in The Lancet and states:
“We searched Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane, and Medline In Process databases for studies published before July 2011, showing differences in SBP between arms, with data for subclavian stenosis, peripheral vascular disease, cerebrovascular disease, cardiovascular disease, or survival. We used random effects meta-analysis to combine estimates of the association between differences in SBP between arms and each outcome…A difference in SBP of 10 mm Hg or more, or of 15 mm Hg or more, between arms, might help to identify patients who need further vascular assessment. A difference of 15 mm Hg or more could be a useful indicator of risk of vascular disease and death.”
Making sure to check blood pressure in both arms can save your life and help doctors catch any type of early heart problems.
Peripheral vascular disease (PVD) can lead to strokes and heart attacks. Like peripheral artery disease, it happens outside of the heart and can cause spasms, narrowing, or complete blockage.
Arteriosclerosis can often lead to PVD, which is when the arteries hardened because of plaque buildup. When this occurs, oxygen and blood flow are restricted and can lead to organ damage or even loss of limbs.
About 12%-20% of people age 60 and older develop PAD, which is a form of PVD and can be used somewhat interchangeably.
People who are overweight, over the age of 50, have heart disease, high blood pressure, or diabetes are at a higher risk of developing PVD. Poor diet and exercise habits can also contribute to it.
If you fall under any of these categories, have your doctor check blood pressure in both arms just to be sure that you don’t have PVD or at high risk for it.
