  Fig. 1.. Sample 0/2 hour pathway for rule-out of myocardial infarction with high sensitivity troponint (Roche Elecsys). *If symptoms less than 3 hrs, repeat troponin in 2 hrs. **If alternative explanation of myocardial injury or troponin elevation other than acute coronary syndrome (e.g., CHF, ESRD) consider repeat testing to assure stability. ACS, acute coronary syndrome; T0, time zero; Delta, change in troponin concentration over time.
