Design outcomes

Primary

Measure	Time frame
Research 1: Factors that influence exercise tolerance and its improvement in patients undergoing TAVI. To examine changes in 6-minute walking distance before and after TAVI and the factors that influence its improvement. Research 2: Factors influencing the improvement of exercise tolerance by cardiac rehabilitation in patients undergoing TAVI. We will examine the factors that affect the frequency and frequency of cardiac rehabilitation and the changes in 6-minute walking distance 5 months after discharge and its improvement.	—
