    Physical working capacity in patients with acquired cardiac valvular defects is inversely related to pressures in the right auricle and pulmonary artery. This finding aligns with existing research on cardiac function and patient classification.

    Area of Science:

    • Cardiology
    • Physiology

    Context:

    • Assessing physical working capacity is crucial for managing patients with acquired cardiac valvular defects.
    • Right heart catheterization provides key hemodynamic data in these patients.

    Purpose:

    • To determine the relationship between physical working capacity and right heart pressures in patients with acquired cardiac valvular defects.
    • To correlate these findings with existing research and clinical classifications.

    Summary:

    • Physical working capacity was measured in 34 patients using a bicycle ergometer.
    • A significant inverse correlation was found between physical capacity and pressures in the right auricle and pulmonary artery.
    • These results support previous research linking physical capacity to functional class and factors like mitral stenosis severity and cardiac insufficiency.
