The Marburg Heart Score (MHS) calculator is a tool designed to assess the risk of coronary heart disease using responses to five specific questions. Each response is assigned a numerical value, and these values are totaled to determine the overall risk level.

The scoring is as follows:

- For individuals who are female and aged 65 years or older, or male and aged 55 years or older:
  - "Yes" receives a score of 1.
  - "No" receives a score of 0.
- If there is a known history of coronary artery disease, cerebrovascular disease, or peripheral artery disease:
  - "Yes" receives a score of 1.
  - "No" receives a score of 0.
- If the pain experienced by the individual worsens with exercise:
  - "Yes" receives a score of 1.
  - "No" receives a score of 0.
- If the pain is reproducible with palpation:
  - "Yes" receives a score of 0.
  - "No" receives a score of 1.
- If the individual assumes a cardiac origin for their pain:
  - "Yes" receives a score of 1.
  - "No" receives a score of 0.

These scores are summed, providing a total score that ranges from 0 to 5. The interpretation of this score is straightforward:

- A score between 0 and 2 suggests a low risk of coronary heart disease.
- A score of 3 indicates an intermediate risk.
- Scores of 4 or 5 denote a high risk.

This system provides a structured way to evaluate heart disease risk, helping to guide further investigation and management based on the total score.

The Marburg Heart Score (MHS) is a clinical calculator used in primary care settings to predict the likelihood of coronary artery disease (CAD) in patients presenting with chest pain. It is particularly useful in identifying low-risk patients who may not require immediate referral for further diagnostic testing, such as angiography. The MHS takes into account five variables: age/gender, known clinical vascular disease, patient assumes symptoms are of cardiac origin, pain worse with exercise, and pain not reproducible with palpation. The score ranges from 0 to 5, with higher scores indicating a higher probability of CAD. The MHS is not recommended for use in patients with known CAD, as it is designed to assist in the initial diagnosis of this condition.
