Use of Cardiopulmonary Exercise Testing to Assess Pulmonary Hypertension in Patients With Rheumatic Mitral Valve Disease: A Comparative Study With Echocardiography

Rheumatic mitral stenosis (RMS) is still a significant public health problem in low-and middle -income countries. Pulmonary hypertension (PH) is a common consequence of RMS and may be used as a surrogate of disease severity. Cardiopulmonary exer-cise testing (CPET) provides a comprehensive assess-ment of the cardiorespiratory systems and can identify indirect signs of PH. To evaluate the relationship between CPET parameters and PH quantified by echo-cardiography in patients with RMS. This cross-sec-tional study retrospectively included thirty patients

Rheumatic mitral stenosis (RMS) remains a significant public health issue in low- and middle-income countries. Pulmonary hypertension (PH) is a common consequence of RMS and can serve as an indicator of disease severity. Cardiopulmonary exercise testing (CPET) offers a comprehensive assessment of the cardiorespiratory system and can identify indirect signs of PH. This study retrospectively evaluated the relationship between CPET parameters and PH quantified by echocardiography in patients with RMS.
