title: [Use of loading tests to detect silent myocardial ischemia].
abstract: A total of 74 patients with postinfarct cardiosclerosis (PC) and stable angina (SA) were examined by Holter monitoring, bicycle ergometry, echocardiography and 201Tl chloride myocardial scintigraphy and loading tests (transesophageal cardiac pacing and isometric hand exercise test). The detection rate for silent myocardial ischemia (SI) was found to be 57.1% with Holter monitoring, 52.3% by bicycle ergometry, 62.5% with echocardiography, 100% with myocardial scintigraphy with loading test and 88.8% with that without the loading test. The detection rate for PC was 33.9, 32.0, 64.7, 81.8, and 56.7%, respectively. Higher SI detection rates in postinfarct patients were more frequently observed when echocardiography and myocardial scintigraphy in combination with loading tests in patients with PC without angina. The efficiency of SI detection in patients with various coronary heart disease increases when loading tests are employed. The loading tests in echocardiography and myocardial scintigraphy ensure the most complete detection of SI in postinfarct patients without angina.
