Patients with −ECG/−Echo imaging results had the least downstream testing (2.3%), followed by +ECG/−Echo (12.8%), and +Echo (33.6%) (p < 0.001). An abnormal postexercise ECG is valid evidence of IHD. A submaximal ECG stress test is useful in clinical and epidemiologic studies and might be useful in assessing the effectiveness of efforts to reduce the risk of IHD. Exercise stress echocardiography (Echo) is a well-validated and commonly used test for the evaluation of suspected coronary artery disease (CAD). 1-3 A normal stress echocardiogram, defined as the absence of any left-ventricular wall motion abnormality at rest or with stress, portends an excellent prognosis. 4-8 In contrast, exercise stress Echo that reveals regional wall motion abnormalities is specific for CAD (specificity 80%-88%) 9 and is associated with an increased risk of adverse Positive or abnormal: Doctors may conclude the stress test is positive for cardiac ischemia—meaning the heart muscle wasn’t getting adequate oxygenated blood during the stress. There are certain ECG and imaging changes that would support this conclusion. There are also clinical findings that could support it.

A submaximal ECG stress test is useful in clinical and epidemiologic studies and might be useful in assessing the effectiveness of efforts to reduce the risk of IHD. Prior work demonstrates a majority of INOCA patients have coronary microvascular (CMD).2 These results support the concept that abnormal stress ECG with normal echo or perfusion test should raise the clinician’s suspicion for CMD and not dismissed as “false-positive”.2 While CMD evidenced by impaired coronary flow reserve predicts elevated MACE,2 ischemia evidenced by traditional stress testing does not stratify risk in this population.3 The results are concordant with evidence from Ischemic electrocardiographic (ECG) changes during vasodilator stress testing in the presence of abnormal myocardial perfusion imaging (MPI) are associated with more severe coronary artery disease (CAD). However, significance of ECG changes during vasodilator stress test with normal MPI has been controversial.
