[Altered left ventricular diastolic function in patients with lymphogranulomatosis]

Area of Science:

• Cardiology
• Oncology
• Echocardiography

Context:

• Hodgkin's disease (HD) is a cancer of the lymphatic system.
• Cardiac complications can arise from HD, including tumor infiltration and treatment side effects.
• Diastolic dysfunction is a key indicator of cardiac health.

Purpose:

• To investigate the impact of Hodgkin's disease on left ventricular diastolic function and intracardiac hemodynamics using Doppler echocardiography.
• To assess the influence of tumor burden, specific HD variants, and chemotherapy on cardiac diastolic function.

Summary:

• Doppler echocardiography revealed impaired elastic characteristics and altered diastolic blood flow in the left ventricle of 28 HD patients.
• Pericardial involvement and advanced tumor intoxication (mixed-cell variant) correlated with more pronounced diastolic dysfunction, left atrial dysfunction, and left ventricular remodeling.
• Chemotherapy exacerbated diastolic blood flow disorders, with increased polychemotherapy courses linked to worsening left ventricular relaxation.

Impact:

• Tumor intoxication and chemotherapy cardiotoxicity are significant contributors to central hemodynamic disorders in HD patients.
• Diastolic dysfunction of the left heart ventricle is a principal component of these hemodynamic changes.
• Findings highlight the need for monitoring cardiac function in HD patients, considering both disease progression and treatment effects.
