The chapters in this monograph detail the past, present and potential future of markers used for the detection of myocardial injury and for risk assessment as part of a cardiovascular disease work-up strategy. The strengths of this extensive overview, written by many of the current leaders in the field, lie in the evidence presented in addressing analytical/technical, clinical, and outcome-assessments of each biomarker currently used in clinical practice, and for those being investigated as potential cutting-edge tools.
