Congestive heart failure (CHF) patients exhibit elevated blood ketone bodies and free fatty acids, indicating a ketosis-prone state. This is likely due to increased lipolysis driven by stress hormones.

Area of Science:

  • Cardiology
  • Metabolic Medicine
  • Endocrinology

Background:

  • Congestive heart failure (CHF) is a complex condition affecting cardiac function.
  • Metabolic alterations in CHF are not fully understood.
  • Ketone body metabolism plays a role in energy balance.

Purpose of the Study:

  • To investigate blood ketone body levels in patients with congestive heart failure (CHF).
  • To compare metabolic and hormonal profiles between CHF patients and controls.

Main Methods:

  • Blood samples were collected from 13 CHF patients and 11 controls.
  • Measured acetoacetate and b-hydroxybutyrate levels during fasting and after glucose infusion.
  • Assessed relevant metabolic and hormonal markers.

Main Results:

  • CHF patients showed significantly higher blood ketone bodies and free fatty acids during fasting and after glucose intake.
  • Elevated noradrenaline and growth hormone, with lower glucagon, were observed in CHF patients.
  • Despite comparable glucose and insulin, the glucagon-to-insulin ratio differed at peak ketonemia.

Conclusions:

  • Severe congestive heart failure (CHF) appears to be a state prone to ketosis.
  • Increased lipolysis, stimulated by stress hormones, likely contributes to elevated free fatty acids and subsequent ketogenesis.
