Shoulder pain may indicate higher heart disease risk: study

Los Angeles: Your shoulder pain may not just be a result of excessive physical strain, say scientists who warn that the condition could point to an increased risk of heart disease, reports PTI.

A new study led by researchers from the University of Utah in the US found that individuals with symptoms that put them at increased risk for heart disease could be more likely to have shoulder problems, including joint pain and rotator cuff injury.

"If someone has rotator cuff problems, it could be a sign that there is something else going on. They may need to manage risk factors for heart disease," said Kurt Hegmann from University of Utah.

Repeated physical stress is most frequently blamed for aggravating shoulder joints and the muscles and tendons that surround them.

Think about a pitcher who throws a baseball 100 times a day. While physical exertion can certainly be an irritant, accumulating evidence points other factors that could also be at play.

Previous research found that people who had an increased risk for heart disease also had a tendency towards carpal tunnel syndrome, Achilles tendinitis and tennis elbow, all musculoskeletal disorders.

The current study adds shoulder problems to the list and takes the connection one step further. The more heart disease risk factors that each of the study participants had racked up - including high blood pressure, high cholesterol, diabetes - the more likely they were to have had shoulder trouble.

As many as 36 participants with the most severe collection of risk factors were 4.6 times more likely than those with none of the risk factors to have had shoulder joint pain.

They were also nearly six times more likely to have had a second shoulder condition, rotator cuff tendinopathy.

Participants with mid-level heart risk were less likely to have had either shoulder condition, at 1.5 to three-fold.

Shared trends bolster that there could be a relationship between heart risk and shoulder problems, but researchers will need to follow up with a prospective study to prove cause and effect.

It may seem like physical strain would be at least just as likely to cause shoulder pain but data from the 1,226 skilled labourers who took part in the study suggest otherwise.

Ergonomists carefully monitored airbag manufacturers, meat, processors, cabinet makers and skilled labourers.

Every forceful twist, push and pull was factored into a strain index assigned to each worker. However a more straining job did not translate to an uptick in shoulder difficulties. Nor did more time spent doing other physical activities.

"Cardiovascular disease risk factors could be more important than job factors for incurring these types of problems," said Hegmann.
