[Evaluation of late surgical results in coronary disease supported by exercise stress test, noninvasive examination and work resumption].
The aim of the study was to assess effectiveness of surgery in management of coronary artery disease (CAD) during long-term follow-up in bearings of physical efficiency and work resumption. 21 males observed during 3-7 years after coronary artery by-pass grafting (CABG) underwent the study. Patients age ranged from 37 to 60 years (mean 51.7) at the beginning of the follow-up. 10 patients had hypertension and 12 suffered from myocardial infarction before CABG. Number of by-pass grafts ranged from 2 to 4. Postsurgical rehabilitation was performed in the cardiological health resort hospital. Assessment was based on anamnesis and physical, ECG, noninvasive as well as ECG bicycle exercise stress examinations. Long-term follow-up proved significant postoperative increase of exercise tolerance expressed by prolongation of ECG exercise test duration as well as augmentation of maximal load and performed work. Left ventricular contractility improvement measured by LVET/PEP and LVETI parameters was also stated. The best results were observed up to 6 years after surgery in patients with grafted left anterior descending artery. Preoperative myocardial infarction did not effect on longterm results of surgery. 75% of patients resumed a work after myocardial revascularization.
