[Prognostic value of exercise tests performed 3 months after coronary artery grafting in evaluation cardiac events. 6 years follow-up].
Prognostic value of exercise test in evaluation of cardiac events were examined in 326 pts after coronary artery bypass grafting (CABG). During 6 years follow up 18 (5.5%) cardiac deaths and 23 (7.1%) myocardial infarctions were observed. Chest pains persisted in 116 pts (35.6%) and 37 (11.3%) pts needed hospital treatment. Coronary and bypass angiography were performed in 25 pts (7.7%) followed by PTCA in 8 pts (2.5%) and CABG in 5 (1.5%) pts. Exercise duration and maximal work capacity in exercise tests were significantly lower in pts with cardiac events. Reasons of exercise termination: ST segment depression, heart rate and blood pressure values were not different in pts with and without cardiac events and didn't have prognostic value. Patients with cardiac events had significantly reduced left ventricle function. The value of ejection fraction influenced significantly relative risk of cardiac death (p < 0.05).
