title: [Value of various criteria of assessment of a test in stress echocardiography in diagnosis of ischemic heart disease].
abstract: Aim of investigation was to study significance of electrocardiographical and echocardiographical criteria of development of angina attack, and their combination in assessment of results of stress echocardiographical tests (stress-echo) with various stress-agents. Stress echocardiography, coronary angiography and left ventriculography were carried out in 928 patients (805 men and 123 women) aged 31 - 72 years with suspected ischemic heart disease (IHD). Attack of angina (AA) was registered in 324 cases, 1.5 mm ST-segment depression (Scapital TE, Cyrillic) -- in 448 tests, disturbances of local myocardial contractility (DLC) at piece exercise -- in 625 patients. Coronaro-ventriculography did not reveal hemodynamically significant coronary artery lesions in 235 patients. Accuracy, sensitivity, and specificity of assessment of stress-echo result were for criterion "ST" 62.1, 56.9, 77.4%, respectively, for criterion "AA" - 50.0, 40.7, 87.0%, respectively, for criterion DLC - 90.7%, 88.9%, 96.2%, respectively, for combinations of criteria "ST+DLC" - 46.1, 30.6, 91.9%, "ST+AA" -- 66.7, 56.1, 97.8, respectively, for "DLC+AA" -- 54.9, 40.5, 97.4%, respectively. Echocardiographic criterion DLC appears to be determinant in assessment of results of stress-echo tests.
