Diagnostic accuracy of resting left ventricular akinesia/hypokinesia in predicting abnormal coronary angiography

摘要

Background Although several reports demonstrate the efficacy of stress echocardiography in diagnosing coronary artery disease, comparable studies on the competence of the same imaging technique at rest are limited. This study aimed to evaluate whether ventricular akinesia/hypokinesia and left ventricular ejection fraction (LVEF)?Methods This study prospectively enrolled 100 diagnostic coronary catheterization candidates. Any routine echocardiography that the candidates had undergone before diagnostic coronary catheterization was reviewed. Patients were subclassified according to the presence and location of ventricular akinesia/hypokinesia, LVEF, and the results of diagnostic coronary catheterization. LVEF?Results Abnormal coronary angiography was significantly associated with akinesia/hypokinesia (OR?=?4.85, P =?0.002) and LVEF?Conclusion The overall diagnostic accuracy of akinesia/hypokinesia and LVEF
