To control the development of people with congenital heart disease (CHD), it is important to follow their aerobic capacity (AC), especially when they exercise. This research aimed to study the progress of AC during a follow-up of adults with CHD. This is a longitudinal study which involved 127 adults with a mean age of 33.8 (11.1) years (57.5% female; 75 moderate CHD and 52 complex CHD) who had undergone two cardiopulmonary exercise tests (CEPT) in at least one year between the first and the second test. The AC and exercise performance (EP) (duration of exercise time, velocity and percentage of grade) were assessed using a ramp protocol over a treadmill. In a mean of 4.5 (2.0) years of follow-up, there was a significant decrease in AC. The VO2peak at baseline was 27.8 (27.7) mL/kg/min (82.9% (20.3%) predicted) versus 26.6 (7.8) mL/kg/min (79.3% (20.8%) predicted) at the end of follow-up. This decline was independent of the body weight increase. There was no significant difference in HRpeak and EP among periods. These results suggest a sign of favorable evolution of adults with CHD. More research is needed to study different factors that could contribute to AC reduction.
