[The prognostic value of electrocardiographic exercise test in patients after acute myocardial infarction].
The subject of this trial were 243 patients with uncomplicated acute myocardial infarction, hospitalized in years 1992-1996, who were made an electrocardiographic exercise test in the second or third week of the in-hospital stay and whose further history in the 2-6 period after myocardial infarction (average follow-up time lasted for 4.0 +/- 1.9 years) was known. The aim of this trial was to determine the influence of the positive exercise test on the long-term prognosis after acute myocardial infarction in a group with uncomplicated acute myocardial infarction. The course of infarction and the frequency of cardiac events (cardiac death, reinfarction, revascularisation) occurrence in 78 patients with positive exercise test (group I) were compared with a group of 165 patients with negative exercise test (group II). Both groups were compared in respect to age, gender, history of myocardial infarction, risk factors and the course of the infarction in the in-hospital period. The multivariable logistic regression analyse showed that the positive exercise test did not have a statistically significant influence on the increase of post-hospital morbidity but it correlates with significantly more frequent use of the invasive treatment and reinfarction during the follow-up period in this group. Negative exercise test in patients with uncomplicated acute myocardial was a significant factor of the good long-term prognosis.
