11. Chest pain score: a novel and practical approach to angina pectoris. A diagnostic accuracy study
ABSTRACT BACKGROUND: The chest pain classifications that are currently in use are based on studies that are several decades old. Various studies have indicated that these classifications are not sufficient for determining the origin of chest pain without additional diagnostic tests or tools. We describe a new chest pain scoring system that examines the rel
