It sounds like the opening of a joke – but high blood pressure is no laughing matter.
If you are anything like the norm, your doctor measures your blood pressure from one arm only and considers it done.
Research now shows this might be inaccurate and therefore extremely dangerous. Doctors think that a one-arm blood pressure test is good enough.
Nothing to suggest the blood vessels in both your arms are NOT equally open or equally obstructed, so why not?
Blood pressure is literally the pressure at which blood flows through your blood vessels. If they’re clear and flexible enough to contract and relax as needed, blood can flow through easily and your blood pressure is normal.
If, on the other hand, they are blocked or their flexibility is compromised, your heart must pump much harder to get the blood through, which increases the amount of pressure in those vessels.
So what’s wrong with measuring blood pressure in one arm only? After all, if something is wrong, wouldn’t it show up in either arm equally?
Researchers from China have just published an analysis of previous scientific studies that proves that one-arm tests can yield very different readings and can actually put you at risk of cardiovascular death.
The seven studies they surveyed were performed on 17,439 subjects from the United States, China, United Kingdom, and South Korea.
They concluded:
1. People whose arms yielded a difference in systolic blood pressure of 10 or more mmHg were 58 times more likely to die of cardiovascular disease than those with a difference of less than 10 mmHg.
2. Those with an inter-arm systolic blood pressure difference of 15 mmHg or higher were 80% more likely to die than those with a difference of less than 15 mmHg.
In other words, the larger the difference between your two arms, the greater your chance of dying of a cardiovascular event.
If you want to ensure that a doctor measures your blood pressure accurately, ask for a simultaneous reading from both arms to get the best results.
