Diabetes-related heart failure

Area of Science:

• Cardiology
• Endocrinology
• Molecular Biology

Background:

• The link between diabetes mellitus (DM) and heart failure (HF) is increasingly recognized.
• Traditional views attributed diabetes-related cardiac dysfunction primarily to coronary artery disease and hypertension.
• Recent guidelines offer definitions for diabetic cardiomyopathy (DMC), but a complete understanding is still evolving.

Purpose of the Study:

• To provide a comprehensive overview of current concepts in diabetic cardiomyopathy (DMC).
• To analyze existing preclinical and clinical evidence regarding DMC.
• To explore novel molecular mechanisms underlying DMC.

Main Methods:

• Review of current scientific literature and guidelines.
• Analysis of preclinical and clinical studies on DMC.
• Synthesis of information on molecular pathways involved in DMC.

Main Results:

• Diabetic cardiomyopathy (DMC) is defined as heart failure (HF) in diabetic patients, irrespective of coronary stenosis or hypertension.
• DMC encompasses both HF with reduced ejection fraction (HF-REF) and HF with preserved ejection fraction (HF-PEF).
• Existing guidelines provide a foundational definition, yet a complete understanding and clear clinical guidelines are still under development.

Conclusions:

• Diabetic cardiomyopathy (DMC) represents a significant clinical challenge at the intersection of DM and HF.
• A thorough understanding of DMC requires integrating evidence from diverse studies and exploring new molecular mechanisms.
• Further research and clearer guidelines are needed to effectively manage DMC.
