Implementation of a high sensitivity cardiac troponin I assay and risk of myocardial infarction or death at five years: observational analysis of a stepped wedge, cluster randomised controlled trial
Objective To evaluate the impact of implementing a high sensitivity assay for cardiac troponin I on long term outcomes in patients with suspected acute coronary syndrome. Design Secondary observational analysis of a stepped wedge, cluster randomised controlled trial. Setting 10 secondary and tertiary care centres in Scotland, UK. Participants 48 282 consecutive patients with suspected acute coronary syndrome. Myocardial injury was defined as any high sensitivity assay result for cardiac troponin I >99th centile of 16 ng/L in women and 34 ng/L in men. Intervention Hospital sites were rando...
