What does my risk score mean? What does “similarity” refer to?

Your Cardiogram risk score gives you a high-level estimate of how closely your health patterns resemble those of users who have reported having a specific medical condition — like hypertension, diabetes, or sleep apnea.

🧠 How the risk score is calculated

Our AI algorithm analyzes up to 15 health and demographic variables, including:

• Resting heart rate

• Steps and activity

• Heart rate during exercise

• Sleep patterns (if available)

• Age, sex, height, and weight

The algorithm compares your data to patterns from Cardiogram users who have self-reported a diagnosis. If your data is statistically similar, your score may indicate a higher likelihood of that condition — not a diagnosis.

📊 What “similarity” means

“Similarity” refers to how closely your data matches the patterns of users who were diagnosed with a condition. For example:

Users with hypertension may share patterns in resting heart rate, exercise recovery, and physical profile.

If your data looks similar, your hypertension risk score may be higher — but that doesn’t mean you have hypertension.

It’s a statistical correlation, not a clinical evaluation.

🩺 Important reminder

Cardiogram’s risk scores:

• Are not medical diagnoses

• Are not FDA-cleared

• Should be used as one of many tools to monitor your health over time

If you’re concerned about your score, we always recommend discussing it with a healthcare provider.
