Objectives To determine the incidence of clinical, cardiac-related endpoints and mortality among patients presenting to an emergency or cardiology department with non-specific chest pain (NSCP), and who receive testing with a high-sensitivity troponin. A second objective was to identify risk factors for the above-noted endpoints during 12 months of follow-up. Design A prospective multicentre study. Setting Emergency and cardiology departments in Southern Denmark. Subjects The study enrolled 1027 patients who were assessed for acute chest pain in an emergency or cardiology department, and in whom a myocardial infarction or another obvious reason for chest pain had been ruled out. Patients were enrolled from September 2014 to June 2015 and followed for 1 year. Main outcome measures Clinical, cardiac-related endpoints (cardiac-related death, acute myocardial infarction, unstable angina and coronary revascularisation) and all-cause mortality. Results Over a period of 1 year, cardiac-related endpoints were found in 19 patients (1.9%): 0 patients experienced cardiac-related death, 2 (0.2%) had myocardial infarction, 4 (0.4%) had unstable angina pectoris and 17 (1.7%) underwent coronary revascularisation. All-cause mortality was observed in seven patients (0.7%). When compared with the general population, the standardised mortality ratio did not differ. The risk factors associated with the study endpoints included male gender, body mass index >25 kg/m(2), previous known coronary artery disease, hypertension, hypercholesterolaemia, diabetes mellitus and the use of statins. A total of 73% of the endpoints occurred in males. Conclusion The prognosis for patients with NSCP is favourable, with a 1-year mortality after discharge that is comparable with the background population. Few clinical endpoints took place during follow-up, and those that did were predominantly in males.
