Initial hospital attendance, screening visit or telephone contact
Angina
During the initial emergency department or equivalent acute medical admissions unit attendance, study visit or telephone contact, the research team will review participants’ clinical history including cardiovascular risk factors, past medical history, standard clinical biochemical and haematological variables, high-sensitivity cardiac troponin concentrations and the 12-lead electrocardiogram. The Seattle Angina Questionnaire (SAQ-7) shortened Rose Angina and EQ-5D-5L questionnaires will also be administered at baseline.
