What Is Cardiovascular Age?
Cardiovascular Age is an estimate of the health of your cardiovascular system in relation to your actual age. It's calculated by measuring your estimated pulse wave velocity (PWV) and evaluating age-related changes in the shape of your heartbeat’s signal. Although Oura Ring does not directly measure your PWV, your photoplethysmograph (PPG) waveform is used to estimate your CVA.
CVA is affected by a number of factors, including diet, exercise, genetic predisposition, blood pressure, cholesterol levels, and smoking. You can slow the aging of your cardiovascular system through regular exercise and changes to your lifestyle and habits.
How to Use Cardiovascular Age
Cardiovascular Age can be found in the Oura App:
- Go to the My Health tab
- Tap on Heart Health
- Tap on Cardiovascular Age
Cardiovascular Age requires at least 14 nights of data from the past 30 days in order to calibrate the first baseline reading. This preliminary baseline can change as your nighttime data accumulates. Wear your ring consistently at night to ensure that you receive regular, accurate readings.
Once the calibration is complete, the app will display a chart of your CVA as compared to your actual age.
Cardiovascular Age is divided into three levels:
- Below: 6 or more years below your actual age
- Aligned: up to 5 years above or below your actual age
- Above: 6 or more year above your actual age
Tap the CVA chart for an expanded view with more detail that includes your estimated PWV in meters per second, along with recent tags and activities. You can scroll this graph back to view previous weeks' data. CVA is a slow-moving metric and lifestyle changes can take several weeks to show a noticeable effect in the app.
Things to Keep in Mind
- If your CVA is higher than your actual age, don't focus on the absolute number. Instead focus on the relative trend of your CVA over time. Regular exercise and changes to diet and other habits can help improve your Cardiovascular Age
- Although Cardio Capacity and Cardiovascular Age are both part of Oura's Heart Health feature, the two measurements do not have a direct impact on each other. Seeing an increase or decrease in one metric will not necessarily mean seeing an increase or decrease in the other
- Cardiovascular Age results may not be valid for users with certain medical conditions, including heart diseases, neurodegenerative diseases, or pacemakers
-
If you do not see your CVA data after having worn your Oura Ring for at least 14 nights, go to My Profile in the
menu of the Oura App and check that the following personal data has been entered:
- Sex assigned at birth
- Height: between 3'6" - 8'2" (1.1-2.5m)
- Age: between 15-120
Oura Ring is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions or illnesses. Please do not make any changes to your medication, nutrition, or workouts without first consulting your doctor or another medical professional.
