What is Heart Age?

Heart Age is an easy-to-understand indicator of your heart's mechanical efficiency, based on how quickly your heart reacts to each beat and how effectively it pumps blood. Your Heart Age is shown relative to your actual age (e.g., "3 years younger"), so you can see at a glance how your cardiovascular health compares.

How is Heart Age Measured?

Heart Age is calculated from two timing markers - how quickly your heart reacts to each beat (Responsiveness) and how long it spends pump blood (Efficiency). These are measured through Impedance Cardiography (ICG) on BodyScan 2, which captures the electrical and mechanical signals of each heartbeat. Together, they reflect the mechanical efficiency of your heart as a pump.

What are the different results I can get?

Your Heart Age is displayed within a range, and the following color-coding will indicate your results:

🟢 = Younger than expected. Your heart’s timing and pump efficiency are performing better than average for your age. Keep up your regular movement and health habits - they’re working.

🔵 = In line. Your heart’s mechanical function is right where it’s expected for your age. No action needed - keep tracking to spot trends early.

🟠 = Older than expected. Your heart’s timing markers suggested reduced mechanical efficiency compared to what’s expected. This doesn’t mean something is wrong - it’s a signal to discuss with your doctor and monitor over time.

Where can I find my Heart Age score?

You can find the Heart Age score in the new Health Tab of the Withings App, currently available to BodyScan 2 and BodyFit users. Support for additional devices will be added in the coming months.

Make sure your Withings app is updated to the latest version (8.8.0 or later).

Tips for measuring Heart Age

For the most accurate Heart Age measurements, please follow these guidelines:

Before taking the measurements

• Always perform a measurement in the same conditions at the same time of day each day.
• Avoid taking measurements immediately after exercising or after consuming caffeine, as these might alter the results.
• Clean the scale (main body and handle) with warm water before stepping on it.
• Dry your body (especially hands and feet) before performing a measurement.
• Remove all rings/hand accessories before performing a measurement to make sure that no metal is touching the electrodes on the handle.

During the measurements

• Wear a light undergarment to avoid skin-to-skin contact.
• Pay attention to the position of your feet on the scale platform, and of your hands and fingers on the handle.
• Do not move during a measurement. This includes bending your knees or elbows.

Note: This is a long-term monitoring indicator, not a medical diagnosis. Consult a healthcare professional for medical advice. Based on established systolic time interval methods (Weissier et al., Circulation 1972) and ESC guidance on left-ventricular systolic function assessment.
