Systemic inflammation in patients with heart failure

D Hasper1, M Hummel, F X Kleber

Summary

End-stage heart failure causes systemic inflammation. Mechanical circulatory support resolves inflammation, but persistent inflammation indicates infection risk, suggesting inflammatory mediator monitoring for therapy effectiveness.

Area of Science:

  • Cardiology
  • Immunology
  • Critical Care Medicine

Background:

  • Chronic heart failure (CHF) can lead to systemic hypoxia and inflammation.
  • Mechanical circulatory support (MCS) aims to improve systemic oxygenation and reduce inflammation.

Purpose of the Study:

  • To investigate systemic inflammation in chronic heart failure and cardiogenic shock.
  • To evaluate the impact of biventricular assist device (BIVAD) systems on systemic inflammation.

Main Methods:

  • Measured plasma levels of cytokines (IL-6, IL-8, TNF-alpha) and soluble adhesion molecules (sVCAM, sE-, sL-, sP-Selectin).
  • Compared patients with CHF (NYHA classes II-III), cardiogenic shock (pre- and post-BIVAD), and coronary artery disease (control).

Main Results:

Related Experiment Videos

  • Patients with cardiogenic shock showed elevated cytokines and soluble adhesion molecules.
  • Successful BIVAD implantation reduced signs of systemic inflammation.
  • Persistent inflammation was observed in patients with infectious complications.

Conclusions:

  • End-stage heart failure presents a systemic hypoxic and inflammatory syndrome.
  • Elevated inflammatory mediators during MCS may signal persistent hypoxia and infection risk.
  • Monitoring inflammatory mediators could assess MCS therapy effectiveness.
