Diabetic cardiomyopathy: pathophysiology and clinical features

Area of Science:

• Cardiology
• Endocrinology
• Pathophysiology

Background:

• Diabetic cardiomyopathy (DCM) is a distinct cardiac pathology in diabetic patients.
• Diabetes mellitus alters cardiac metabolism, leading to impaired energy production and contractile dysfunction.
• Microvascular changes and extracellular matrix remodeling contribute to DCM pathogenesis.

Purpose of the Study:

• To review current knowledge on the pathogenesis and clinical features of diabetic cardiomyopathy.
• To summarize advancements in early detection methods for DCM.
• To identify unmet needs in the prevention and treatment of diabetic cardiomyopathy.

Main Methods:

• Review of basic and clinical studies on diabetic cardiomyopathy.
• Analysis of metabolic and signaling pathway alterations in the diabetic heart.
• Evaluation of advanced echocardiographic techniques and magnetic resonance spectroscopy for DCM detection.

Main Results:

• Diabetes enhances fatty acid metabolism and suppresses glucose oxidation in the heart.
• Impaired excitation-contraction coupling and increased susceptibility to ischemia/reperfusion injury are key features.
• Sensitive imaging modalities enable early DCM detection and differentiation from other heart diseases.

Conclusions:

• Diabetic cardiomyopathy is a common, often unrecognized condition in asymptomatic diabetic patients.
• Current diagnostic tools allow for early identification of DCM.
• Effective strategies for DCM prevention and treatment are still needed to improve patient outcomes.
