title: High-sensitivity troponin: where are we now and where do we go from here?
abstract: High-sensitivity troponin (hsTn) assays are used clinically in most parts of the world and are expected to be approved by the US FDA for clinical use in the USA soon. Clinical use of hsTn leads to improvements in the detection of myocardial injury, shorter time to ruling out acute myocardial infarction, improved risk-stratification of patients with heart failure and atrial fibrillation among others. HsTn may also guide strategies for primary and secondary prevention of cardiovascular disease. However, unmet challenges remain, including distinguishing between acute and chronic hsTn elevations, distinguishing between type 1 and type 2 acute myocardial infarction and determining whether to use gender-neutral or gender-specific reference values.
