Low Athens QRS score may flag false-negative stress tests for angiography referral; leaves open prospective validation before routine adoption.
Does a low Athens QRS score predict obstructive coronary artery disease in patients with chest pain and a normal exercise stress test?
A low Athens QRS score (≤5) is a strong independent predictor of obstructive CAD in patients with chest pain despite a normal exercise stress test.
