Key result
Graded exercise testing in patients with resting ST depression detected coronary artery obstruction with a sensitivity of 0.92 and specificity of 0.75.
Why the study?
Does near maximal graded exercise testing accurately detect coronary artery obstruction in patients with resting ST-segment depression?
Observational (n=37)
Does near maximal graded exercise testing accurately detect coronary artery obstruction in patients with resting ST-segment depression?
Effect estimate: Sensitivity 0.92, Specificity 0.75
Exercise stress testing is safe and provides high sensitivity for detecting coronary artery obstruction in selected patients who already have abnormal ST segments at rest.

May support graded exercise testing for obstruction detection in resting ST depression; leaves open confirmation in larger prospective studies.
Kansal et al. (1976) conducted an observational in Chest pain with resting ST-segment depression (n=37). Graded exercise test (additional ST depression ≥0.1 mV) vs. Coronary angiogram was evaluated on Coronary artery obstruction (Sensitivity 0.92, Specificity 0.75). Graded exercise testing in patients with resting ST depression detected coronary artery obstruction with a sensitivity of 0.92 and specificity of 0.75.
