Key result
Exercise echocardiography of atrioventricular plane displacement identifies CAD with ~80% sensitivity.
Why the study?
The effect of exercise on atrioventricular plane displacement and its utility in detecting reversible myocardial ischaemia in patients with coronary artery disease was not established.
Does exercise echocardiographic recording of atrioventricular plane displacement accurately detect reversible myocardial ischaemia in patients with stable angina?
Observational (n=68)
Does exercise echocardiographic recording of atrioventricular plane displacement accurately detect reversible myocardial ischaemia in patients with stable angina?
Effect estimate: Sensitivity 80%, Specificity 100%
Exercise echocardiographic recording of atrioventricular plane displacement is a simple and accurate non-invasive method for identifying patients with coronary artery disease.

High specificity supports diagnostic utility in stable angina; leaves open prospective validation against standard ischaemia tests.
A 1991 study conducted an observational in Coronary artery disease (n=68). Exercise echocardiographic recording of atrioventricular plane displacement vs. Healthy subjects was evaluated on Identification of coronary artery disease patients (Sensitivity 80%, Specificity 100%). Exercise echocardiographic recording of atrioventricular plane displacement identified patients with coronary artery disease with an overall sensitivity of 80% and specificity of 100%.
