INTRODUCTION:
Given the advances in diagnosis and clinicalsurgical therapies, congenital heart defects are increasing their prevalence in the adult population. Yet, there is still no consensus on the best way to follow up with these patients. Among the validated tools for monitoring patients with heart disease, the Cardiopulmonary Exercise Test (CPET) plays an important role. However, the use of this test for monitoring the population of Grown Up Congenital Heart (GUCH) still lacks studies. This study aimed to assess the correlation between ergospirometry variables and the severity of the GUCH population measured by echocardiographic aspects.METHODS:
A retrospective cohort with 248 GUCH (Table 1) over 18 years old, was referred to CPET, from 2015 to 2021, in a tertiary hospital in the state of São Paulo. Patients were sequentially included, and those in functional class IV or with contraindications to CPET were excluded. Ergospirometry variables were analyzed in association with ventricular function - estimated by echocardiogram in the same period.RESULTS:
Most patients were in functional class I and II (86.3%). In the echocardiographic findings, 40% had pulmonary hypertension and almost all had preserved left ventricle function. The CPET showed a median VO2 peak around 69% of predict. Other parameters are summarized in Table 2. CPET variables were able to stratify the severity of GUCH, mainly by pulmonary hypertension. Comparing CPET data and imaging diagnosis, VE/VCO2 slope> 32 and OUES <60% were related to the presence of pulmonary hypertension.CONCLUSION:
The CPET is an important resource for prognostic and diagnostic definition in the evolution of GUCH patients.
