[Painless ST segment depression during exercise stress tests in patients after acute myocardial infarct].
A group of 125 patients (of the total of 400 patients) had ischaemic ST-segment depression (greater than or equal to 1 mm) on exercise electrocardiogram. Of 125 patients with ischaemic response on exercise electrocardiogram 83 (66.4%) patients had both ST-segment depression and anginal pain, and 43 (33.6%) patients were without ischaemic symptoms during exercise testing. There was no difference with regard to sex and age between patients with and without anginal pain. There was no difference in frequency of arterial hypertension, but diabetes mellitus was more frequent in patients with painless ST-segment depression than in patients with painful ST-segment depression. Left ventricular function was more deteriorated in patients with painless ST-segment depression (PEP/LVET = 0.390 +/- 0.028) than in symptomatic patients (PEP/LVET = 0.366 +/- 0.042; P/0.001). There was no difference in heart rate on peak exercise and in magnitude of ST-segment depression in patients with and without anginal pain.
