This study looked at whether a 6-minute stepper test (ST6) can accurately measure exercise tolerance in people with heart conditions undergoing rehabilitation. Researchers compared the stepper test results with the standard 6-minute walk test and a cardiac stress test in 60 patie…

This completed study followed 427 children under 14 who had surgery for mitral regurgitation (a leaky heart valve) at eight hospitals in China. Researchers compared two surgical repair strategies to see which led to better outcomes, like survival and avoiding repeat surgery. The …

This study followed 77 patients under 60 who had a mechanical aortic valve replacement to see if a mismatch between the valve size and the patient's body affects heart recovery and exercise ability. Participants did exercise tests and heart ultrasounds years after surgery. The go…
