Data from 54,000 people were examined in studies that spanned 4 different continents, and those with measurement data from both arms were examined in terms of MI, cerebrovascular event and mortality.

Normally, small blood pressure differences between the two arms (up to 10mmHg are considered physiological, but may also indicate pathological conditions, the aforementioned condition should be evaluated by specialist physicians), although there is usually no symptom of any health problem, new research has focused on this situation.

The study, conducted internationally and involving more than 50,000 subjects, claimed that the severity of the difference in blood pressure between the two arms correlated with the risk of heart attack, stroke and premature death, in other words, the more the difference is, the higher the risk.

Currently, according to current guideline (guideline), if the blood pressure difference between the two arms is higher than 20mmHg, advanced examination, screening and consultation (consultation) are required.

Guideline or guide
According to the authors of the new study, this situation in the guidelines is largely ignored. In addition, as the difference between the two arms increases, the cardiovascular risk increases. For this reason, blood pressures must be measured and recorded from both arms.

Data from 54,000 people were examined in studies that spanned 4 different continents, and those with measurement data from both arms were examined for 10 years in terms of MI (heart attack), cerebrovascular event (stroke) and mortality (death).

As a result of the studies conducted, each mmHg increase in systolic pressure measured between the arms increases the risk of angina (pain), MI and cerebrovascular events by 1% during the following 10-year period, in other words, each 1mmHg difference means an increasing risk of 1%.

Currently, the figure recommended as 20 mmHg in international guidelines has been reduced to 15mmHg in the UK and some European countries, but the Mayo Clinic has taken this a little further and reduced this figure to 10 mmHg.
