Thorask is a diagnostic medical expert system, which assists health professionals, and managed care providers in optimizing the triage, diagnosis, and management of non-traumatic chest pain.

Thorask is a straightforward, easy to use program requiring only the input of carefully obtained clinical information. The program includes a module for the less experienced to help distinguish the three principal categories of chest pain (typical angina, atypical angina, non-angina) from each other. After the physician has answered basic questions about the patient’s history, and directed physical findings, which takes him 3–7 minutes, the program immediately displays a list of diagnoses. The diagnoses are presented in decreasing order of likelihood, together with their estimated probabilities. The program also provides concise descriptions of relevant clinical conditions and their presentations as well as brief suggestions for diagnostic approaches. For purposes of record keeping, documentation, and data analysis, there are options for saving and printing cases.
