Cardiac rehabilitation improves the subjective condition of the patient; but are there associated structural and functional cardiac adaptations? The study group consisted of 39 patients with an inferior infarction and 21 patients with an anterior infarction, treated by surgical revascularization followed by 4 months of cardiac rehabilitation. Maximal exercise testing and Doppler echocardiography were performed before and after the rehabilitation program. Performance capacity was significantly improved after cardiac rehabilitation, but left ventricular function remained unchanged on Doppler imaging. Only by analyzing the subgroups using strain imaging significant differences were noted after cardiac rehabilitation: patients with an inferior infarction exhibited improved strain values in the anterior wall; those with an anterior infarction had improved strain values in the inferior wall. Strain values in the infarcted regions were worse after cardiac rehabilitation. Strain imaging indicated that cardiac rehabilitation could bring about improvements in cardiac function exclusively in the healthy non-infarcted myocardium, while there were signs of further deterioration of myocardial function in the highly ischemic zones.
