NCT01838148

Brief Summary

The primary aim is to perform the largest study worldwide to evaluate novel biochemical and electrocardiographic signatures alone as well as in combination with the standard 12-lead exercise ECG in the detection of exercise-induced myocardial ischemia (diagnostic endpoint). The secondary aim is to evaluate these innovative tools in the risk prediction for the occurrence of cardiovascular death and acute myocardial infarction during long-term follow-up.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic utility of novel biochemical and electrocardiographic signatures

    Diagnostic utility of biochemical (i.e. cardiac troponin, brain natriuretic peptide) and electrocardiographic signatures alone as well as in combination with the standard 12-lead exercise ECG in the detection of exercise-induced myocardial ischemia, mainly quantified by the area under the receiver operating characteristics curves (AUC ROC) and positive/negative predictive values, respectively.

    baseline

Secondary Outcomes (4)

  • One year event-free survival

    360 days

  • Two year event-free survival

    2 years

  • Five year event-free survival

    5 years

  • Eight year event-free survival

    8 years
