Insights

A new LIVER-ASCVD+ model improves cardiovascular risk prediction in patients with Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) and Metabolic Dysfunction-Associated Steatohepatitis (MASH). This model integrates liver biomarkers, offering better accuracy than existing tools for these high-risk populations.

Area of Science:

  • Cardiology
  • Hepatology
  • Epidemiology

Background:

  • Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) and Metabolic Dysfunction-Associated Steatohepatitis (MASH) are growing global health concerns.
  • Current cardiovascular disease (CVD) risk models inadequately predict events in MASLD/MASH patients.

Purpose of the Study:

  • To develop and validate a novel regression model, LIVER-ASCVD+, for enhanced CVD risk prediction in MASLD/MASH patients.
  • To integrate traditional cardiovascular risk factors with liver biomarkers for improved accuracy.

Main Methods:

  • A retrospective cohort study of 9,185 biopsy-confirmed MASH patients.
  • Comparison of LIVER-ASCVD+ model performance against the ASCVD Risk Estimator Plus.
  • Kaplan-Meier survival analysis and propensity-matched control cohorts.

Main Results:

  • LIVER-ASCVD+ showed superior predictive accuracy for myocardial infarction/stroke (AUC: 0.68) and mortality (AUC: 0.63) versus ASCVD Risk Estimator Plus (AUCs: 0.63 and 0.54).
  • The model effectively stratified patients into distinct risk categories with significant outcome differences.
  • Kaplan-Meier analyses confirmed the model's enhanced predictive capability.

Conclusions:

  • Integrating liver biomarkers significantly improves CVD risk prediction in MASLD/MASH patients.
  • The LIVER-ASCVD+ model offers a promising tool for clinical decision-making and improving patient outcomes.
  • Further validation of the LIVER-ASCVD+ model is recommended.

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Physiological Pharmacokinetic Models: Incorporating Hepatic Transporter-Mediated Clearance

Drug transporters are critical in drug absorption, distribution, and excretion processes. They should be included in physiological-based pharmacokinetic (PBPK) models, which help predict human drug disposition. However, predicting this is challenging during drug development, especially when liver transport is involved. However, with a realistic representation of body transport processes, an accurate model may be possible.

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

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:
