Introduction: Coronary artery disease (CAD) is the leading cause of heart failure (HF). Only viable dysfunctional myocardium (hibernation) is potentially recoverable with restoration of adequate perfusion. Cardiac imaging modalities have emerged with the ability to differentiate between myocardial scar and viable myocardium and are now often used to direct therapy decisions including revascularization. Decrease in wall motion score (WMS) and improvement in LV ejection fraction (LVEF) during DSE is considered as a surrogate marker for viability of myocardium. It is largely unknown how cardiac specific biomarkers are released in relation the presence and extent of hibernation in patients with ischemic HF. The objectives of this study are to assess the relationship and interaction of the biomarkers BNP and hs TnI with hibernation in patients with chronic ischemic HF.
