ECG changes during adenosine stress are not uncommon. It shows a moderate strength of association with reversible perfusion defects. ECG changes during adenosine merit critical evaluation of MPS findings.
Coronary Artery Disease (CAD) is the leading cause of death and disability of mankind. There are various screening and diagnostic tests available for evaluating CAD. We tried to evaluate Duke's treadmill score and Myocardial perfusion scan for evaluating CAD with invasive coronary angiogram as gold standard; 130 patients were included in the study. All underwent treadmill test and MPS. In results it was found that patients with High (7%) and Low (32%) Duke's score, MPS did not add much incremental value. But majority of the patients fell in moderate Duke's score (60%). MPS played a major role in this moderate Duke's score, which sub-classified it into Normal (64%), Mild (22%) and Severe (7.7%). In addition, correlation of MPS with invasive angiogram was very good with sensitivity of 85-90% and specificity of 87-100%. MPS plays important role in evaluating CAD, in that it provides incremental value in patients with moderate Duke's treadmill score.
