Insights

In cirrhosis patients with ascites, advanced left ventricular diastolic dysfunction (LVDD) is linked to inflammation, worsening kidney function, and increased risk of hepatorenal syndrome (HRS) and death. Early detection of LVDD is crucial for managing these complications.

Area of Science:

  • Cardiology
  • Hepatology
  • Nephrology
  • Internal Medicine

Background:

  • Left ventricular diastolic dysfunction (LVDD) is a common cardiac issue in cirrhosis patients.
  • The relationship between LVDD, systemic inflammation, and clinical outcomes in cirrhosis with ascites requires further investigation.

Purpose of the Study:

  • To examine the association between LVDD and systemic inflammation in patients with cirrhosis and ascites.
  • To determine the impact of LVDD on renal function, hepatorenal syndrome (HRS) development, and survival.

Main Methods:

  • Prospective enrollment of 215 patients with cirrhosis and ascites.
  • Assessment of LVDD using Doppler echocardiography.
  • Measurement of inflammatory markers, systemic hemodynamics, vasoactive factors, and radioisotope-assessed renal function.
  • Monitoring for HRS development and liver-related mortality over 5 years.

Main Results:

  • LVDD was diagnosed in 66% of patients; grade 2/3 LVDD was present in 43%.
  • Serum lipopolysaccharide-binding protein (LBP), plasma renin activity (PRA), and glomerular filtration rate (GFR) were independently associated with LVDD severity.
  • Advanced LVDD (grade 2/3) was linked to higher 5-year risks of HRS (35.5% vs. 14.4%) and death (53.3% vs. 28.2%) compared to grade 1.
  • The diastolic function marker E/e' strongly correlated with LBP, PRA, and GFR in LVDD patients.

Conclusions:

  • LVDD occurrence and severity in cirrhosis with ascites correlate with inflammatory activity.
  • Advanced LVDD is associated with circulatory and renal dysfunction, increasing the risk of HRS and mortality.

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
