Published online: 21 January 2013

To the Editor: Scott and colleagues address the vexed issue of using highly sensitive (hs) cardiac troponin (cTn) assays to detect myocardial infarction (MI) and likely increases in hospitalisations.1 Greater numbers of MIs detected by hs-cTn assays also confound population surveillance of MI trends and our understanding of disease prevention.
