[Evaluation of patient rehabilitation effectiveness after aortic valve prosthesis based on spiroergometric study data].

Patients after surgery introducing aortal valve prosthesis in cases of rheumatic aortal defect or defect due to bacterial endocarditis were examined using spiro- and bicycle ergometry. Two groups of patients were compared: those subjected to rehabilitation procedures and a control group undergoing no rehabilitation program. Functional results were better in post-rehabilitation patients. By the end of the rehabilitation program, the examined spiroergometric parameters were significantly closer to those of normal subjects, as compared to the controls. Spiroergometric investigation in patients with newly applied aortal valve prostheses supplements clinical data in providing a more profound functional evaluation of surgical results and rehabilitation efficiency.
