Role of serum troponin-l in identifying left ventricular ejection fraction of

To determine the serum levels of troponin-l in identifying left ventricular ejection fraction [LVEF] of 63.5 ng/ml predicted LVEF of <40% with a sensitivity of 94% and specificity of 97% in patients receiving streptokinase, whereas in patients undergoing primary PCI, troponin-l levels of > 87.5 ng/ml predicted LVEF < /=40% with a sensitivity of 86% and specificity of 100%. Troponin-l concentration of > 63.5 ng/ml and > 87.5 ng/ml can predict LVEF
