[Changes in central hemodynamics in chronic liver diseases (radiocardiologic study)]
Insights
Chronic liver disease patients exhibit distinct hemodynamic circulation types. Cirrhosis with ascites shows increased hyperkinetic circulation and reduced blood volume, impacting treatment strategies.
Area of Science:
- Cardiology
- Hepatology
- Medical Imaging
Context:
- Chronic liver diseases (CLD) significantly alter systemic hemodynamics.
- Understanding hemodynamic profiles is crucial for managing CLD complications.
- Radionuclide cardiography offers a method to assess cardiac function and blood volume in CLD.
Purpose:
- To define hemodynamic circulation types in patients with chronic liver diseases.
- To investigate the relationship between liver cirrhosis, ascites, and hemodynamic patterns.
- To correlate hemodynamic types with circulating plasma and blood volumes in CLD.
Summary:
- Three hemodynamic circulation types (hyperkinetic, eukinetic, hypokinetic) were identified in 136 CLD patients.
- Liver cirrhosis with ascites was associated with a significant increase in hyperkinetic circulation, often linked to hypervolemia.
- Hypokinetic circulation in cirrhotic patients with ascites correlated with decreased plasma and blood volumes, suggesting careful diuretic use.
Impact:
- The findings highlight the hemodynamic heterogeneity in CLD, influenced by disease progression and underlying genetic factors.
- Identified hemodynamic patterns can inform personalized treatment approaches for CLD patients.
- This study underscores the importance of considering hemodynamic status, particularly blood volume, when managing ascites in liver cirrhosis.
Abstract:
Some indices of central hemodynamics: cardiac and systolic indices, specific peripheral resistance and circulating plasma and blood volumes were studied in 136 patients with chronic liver diseases using radionuclide cardiography. I. Three hemodynamic types of blood circulation (hyper-, eu- and hypokinetic) were defined in patients with chronic liver diseases as well as in healthy persons. II. In liver cirrhosis and ascites the number of patients with the hyperkinetic type of circulation increased significantly, mainly at the expense of patients with hypervolemia. III. A significant decrease in circulating plasma and blood volumes was noted in patients with liver cirrhosis complicated by ascites, with the hypokinetic type of circulation. It should be borne in mind in administration of diuretics to such patients. The above results suggested that different types of circulation in patients with chronic liver diseases were formed under the influence of the disease against a background of existing constitutionally and genetically determined hemodynamic heterogeneity.
