Performance of risk scores for coronary artery disease: a retrospective cohort study of patients with chest pain in urgent primary care.

Objective: To evaluate the diagnostic performance of the Marburg Heart Score (MHS), INTERCHEST, Gencer rule, Bruins Slot rule and compare these with unaided clinical judgement in patients with chest pain in urgent primary care.

Design: Retrospective, cohort study.

Setting: Regional primary care facility responsible for out-of-hours primary care for a quarter-million people in the Netherlands.

Performance of a simplified HEART score and HEART-GP score for evaluating chest pain in urgent primary care.

Background: Chest pain is a common symptom in urgent primary care. The distinction between urgent and non-urgent causes can be challenging. A modified version of the HEART score, in which troponin is omitted ('simplified HEART') or replaced by the so-called 'sense of alarm' (HEART-GP), may aid in risk stratification.
