In the October 2024 study titled “Arm Position and Blood Pressure Readings: The ARMS Crossover Randomized Clinical Trial,” published in JAMA Internal Medicine,1 researchers explored how different arm positions during blood pressure measurement affect the accuracy of the readings. This inaccurate measurement could misdiagnose up to 54 million American adults with hypertension.
Accurate blood pressure measurements are more important than you might think. Hypertension, often called the silent killer, is the leading cause of cardiovascular disease and preventable death worldwide. Every year, millions suffer from heart attacks and strokes, stemming from unmanaged high blood pressure.
When you visit your doctor, the blood pressure reading you receive plays a role in determining your health plan. If your blood pressure is inaccurately measured, it will lead to serious consequences. Overestimation might result in unnecessary medications and stress, while underestimation could mean missing a critical diagnosis that needs immediate attention.
- Physiological factors like changes in hydrostatic pressure and decreased venous return cause elevated readings when arms aren’t properly supported at heart level during measurement
- Misdiagnosis due to improper arm positioning impacts treatment decisions, leading to unnecessary treatments that put you at risk of other health complications
- Ensuring standardized arm position during blood pressure measurement and using appropriate equipment like adjustable armrests is important for accurate diagnosis. Strategies to protect your heart health are also included below
