Can noninvasive exercise test criteria identify patients with left main or 3-vessel coronary disease after a first myocardial infarction?

Low-level exercise testing after myocardial infarction: usefulness in enhancing clinical risk stratification.

“…A heart rate of 120 beats/min or greater was attained by 202 patients during the limited test, 17 of whom died within 1 year (8.4%) compared with 14 of the 464 (3%) whose heart rate did not exceed this threshold (p < .01). This end point, as anticipated, was influenced by the presence of a /3-blocking agent at the time of the test.…”

Significance of hypotensive response during dobutamine stress echocardiography

“…In patients unable to perform exercise testing, dobutamine stress echocardiography (DSE) is a useful alternative because of its ability to reproduce physiologic responses to exercise stress, ease of use, patient acceptance and safety [1][2][3][4]. A hypotensive response to exercise stress has been shown to correlate with severe coronary artery disease as well as poor cardiac prognosis [5][6][7]. Hypotensive response occurring during dobutamine stress testing appears to be more common, with an occurrence of 14-48% [8,9].…”

Studies on ergometer exercise testing I. Significance of the type of st‐segment response, sex, and chest pain

“…However, subjects with a poor chronotropic response may have significant CAD with a negative EECG (Ellestad and Halliday, 1977;Patterson et al, 1983). STsegment elevation has been considered significant in a minority of studies (Berman et al, 1978;Campos et al, 1983;Detry et al, 1977;McNeer et al, 1978).…”
