Heart Failure and Diabetes Mellitus: Dangerous Liaisons

Area of Science:

• Cardiology
• Endocrinology
• Metabolic Diseases

Background:

• Diabetes mellitus (DM) significantly increases heart failure (HF) prevalence.
• Approximately 40% of HF patients have DM, experiencing worse clinical outcomes.
• A bidirectional relationship exists, with HF increasing DM onset risk via insulin resistance.

Purpose of the Study:

• To review the epidemiology of DM-induced HF (DM-HF).
• To elucidate the pathogenic mechanisms underlying DM-HF.
• To discuss current and future treatment strategies for DM-HF.

Main Methods:

• Literature review of epidemiological data.
• Analysis of pathophysiological mechanisms.
• Synthesis of therapeutic approaches.

Main Results:

• DM is a major risk factor for HF development and progression.
• Pathophysiology involves endothelial and renal dysfunction, obesity, and impaired myocardial energetics.
• Insulin resistance is a key mechanism linking HF to DM onset.

Conclusions:

• DM-HF represents a significant clinical challenge with complex pathophysiology.
• Effective management requires addressing both DM and HF components.
• Further research into targeted therapies for DM-HF is warranted.
