Objective: The aim of this study was to investigate the ability of
Athens QRS score values to detect stenoses in other coronary arteries
than the obstructed ones (which caused the myocardial infarction [MI])
in patients with a history of MI.
Methods: We studied 125 patients (93 males and 32 females, mean age 54
+/- 7 years [range 4568 years]) with a history of MI (46 patients with
anterior MI, 54 patients with inferior MI, 25 patients with lateral MI).
All patients underwent treadmill exercise testing and coronary
arteriography.
Results: Athens QRS score values were inversely related to the extent of
CAD: -0.5 +/- 0.3 mm for patients with 1-VD (obstructed vessel), -3.4
+/- 2.2 mm for patients with 2-VD (obstructed vessel and stenosis in
another vessel), and -5 +/- 1.8 mm for patients with 3-VD (obstructed
vessel and stenoses in two more vessels). The ROC curves for the
detection of multivessel disease showed that the area under the curve
for QRS score values < -3 mm is significantly higher than the curve for
ST-segment depression greater than or equal to1 mm (0.948 vs 0.792, P <
0.001).
Conclusions: Values of the Athens QRS score less than -3 may distinguish
single- from multivessel coronary artery disease in patients with a
history of MI.
