[Initial occurrence of angina: diagnostic value of bicycle ergometry and Holter ECG monitoring].
The diagnostic value of exercise tests and Holter's ECG monitoring was assessed in 111 patients within the first 3 months since the onset of anginal attacks; 22 of those had a history of large-focal myocardial infarction. Coronaro-angiography was performed in all cases, and its results were compared with those of exercise tests in 107 patients, and of Holter's ECG monitoring, in 104. Bicycle ergometry was positive in 48% of patients. In Holter's ECG monitoring, ST changes were found in 53% of patients. Combined use of bicycle ergometry and Holter's monitoring allowed detecting ST displacement in 60%. Ischemic ST depression during bicycle ergometry in postinfarction patients is an evidence of polyvascular coronary arterial involvement.
