Coronary artery calcium scan
For cardiovascular risk assessment
The experts we follow agree on this.
A coronary artery calcium scan is a strong tool for assessing heart health risk early.
Who is behind it
Voices including a molecular biology PhD, a former research biochemist and a board-certified cardiologist.
How strong the research is
Mostly expert experience so far, with published research still catching up.
In their words
“the ct coronary calcium score which is a low-dose radiation scan of your heart arteries... if your score is higher than zero means you do have some plaque building up”
a board-certified cardiologist
CAC scans are considered the most effective predictor of coronary heart disease as they directly report on disease status unlike blood tests.
A coronary calcium scan with a score of zero indicates no current cardiovascular disease progression and can be tracked over time.
You have 60,000 miles of blood vessels and plaque can be present elsewhere, so starting treatment if plaque is found anywhere is important.
CAC score is a good first step for screening coronary artery disease as it is fairly inexpensive and exposes patients to low radiation compared to other tests.
CAC can reveal calcified plaque indicating higher cardiovascular risk not evident from cholesterol alone.
A cardiologist performs the tilt table test to diagnose POTS by measuring heart rate changes.

How this reading was made
Every line here comes from a doctor, scientist or coach speaking publicly, and links to the moment they said it. Entrain listens for where independent experts arrive at the same place on their own, and shows where they part ways. Mostly expert experience so far, with published research still catching up.

Keep exploring heart and longevity
The experts agree
Blood pressure measurement
Regular blood pressure checks are a practical tool for heart and vessel health.
The experts agree
Cholesterol in context
Focus on metabolic health rather than cholesterol numbers alone, using tests to identify who truly needs treatment.
Most recommend it
Improving heart rate variability
Monitor and improve heart rate variability to gauge resilience and support hormonal and metabolic health.
Worth exploring
Statins
Statins are worth exploring for heart risk, but side effects and benefits vary by situation.

Smoking cessation
Our sources steer away from smoking due to clear health risks.
