The HEART Score for Chest Pain is a clinical calculator used in the evaluation of patients presenting with chest pain in the emergency department. The acronym HEART stands for History, ECG, Age, Risk Factors, and Troponin, which are the five elements used to calculate the score. 

This scoring system is designed to stratify risk in patients with chest pain, helping clinicians to decide whether a patient can be safely discharged, requires further diagnostic testing, or needs immediate intervention. It is particularly useful in identifying patients at low risk of major adverse cardiac events within the next six weeks.

There are no specific exclusion criteria for the use of the HEART Score, but it should be noted that it is not designed to replace clinical judgment. It should be used as a tool to aid decision-making in conjunction with a thorough clinical assessment.

# Scoring:
- If score == 0, then Low score (0): risk of major adverse cardiac events is 0.9-1.7%
- If score == 1, then Low score (1): risk of major adverse cardiac events is 0.9-1.7%
- If score == 2, then Low score (2): risk of major adverse cardiac events is 0.9-1.7%
- If score == 3, then Low score (3): risk of major adverse cardiac events is 0.9-1.7%
- If score == 4, then Moderate score (4): risk of major adverse cardiac events is 12-16.6%
- If score == 5, then Moderate score (5): risk of major adverse cardiac events is 12-16.6%
- If score == 6, then Moderate score (6): risk of major adverse cardiac events is 12-16.6%
- If score == 7, then High score (7): risk of major adverse cardiac events is 50-65%
- If score == 8, then High score (8): risk of major adverse cardiac events is 50-65%
- If score == 9, then High score (9): risk of major adverse cardiac events is 50-65%
- If score == 10, then High score (10): risk of major adverse cardiac events is 50-65%)
