Diagnostic significance of myocardial and multimodal contrast exercise stress echocardiography in the detection of hemodynamically significant coronary artery stenosis in stable angina pectoris

Aim . To evaluate the diagnostic significance of myocardial contrast stress echocardiography (MCSE) and multimodal (MMSE) with dosed exercise in detecting hemo­dynamically significant coronary artery stenosis patients stable heart disease (CAD) without impaired regional left ventricular contractility at rest. Material methods MCSE MMSE were performed 61 pa­­tients suspected or CAD (mean age, 62,9±8,9 years). All underwent angiography. During MCSE, perfusion assessed. With MMSE, was Sensitivity, specificity, positive (LR+) negative (LR-) likelihood ratios for assessed com­parison Results The sensitivity assessment 82% (CI, 67-92%) specificity 70% (35-92%), LR+ — 2,74, LR- 0,26. Sensitivity 67% (50-81%) 90% (65-99%), 6,67, 0,37. an estimate 74% (58-87%) a (56-98%), 7,4, 0,28. mode cavitary contrasting 72% (55-85%) (56-99%), 7,18, 0,31. Conclusion are importance detection CAD, result which increases post-test probability hemodynamically stenosis. A isolated does not have diagnostically effect on CAD.
