INTERCHEST clinical prediction rule for chest pain in primary care

The INTERCHEST clinical prediction rule is a diagnostic tool used in primary care settings to evaluate patients presenting with chest pain. The name "INTERCHEST" is an abbreviation derived from the study "International Chest pain prediction rule" which developed this tool. This calculator is specifically designed for adult patients who present to primary care with chest pain. Its primary clinical utility is to help clinicians estimate the probability of coronary artery disease (CAD) in these patients. By considering various patient characteristics and symptoms, the INTERCHEST rule provides a score that can predict the likelihood of CAD, thereby aiding in decision-making about further diagnostic testing and management. The INTERCHEST rule should not be used in patients with known CAD, those with a clear alternative diagnosis for their chest pain, or those with chest pain due to trauma. It is also not intended for use in emergency settings, where more acute causes of chest pain (such as myocardial infarction) need to be ruled out.
