High-sensitivity cardiac troponin (hs-cTn) assays allow more rapid rule-in and rule-out of myocardial infarction (MI) compared with conventional troponin assays. A recent nationwide cohort study including 87,879 patients with a first MI revealed that although the use of hs-cTn had no impact on survival, it was associated with increased incidence of MI. In addition, the study found that use of hs-cTn reduced risk of reinfarction while also increasing the use of coronary angiography and revascularization.
