Coronary microvascular dysfunction in diabetes mellitus: A review

Area of Science:

• Cardiovascular Medicine
• Endocrinology
• Pathophysiology

Background:

• Diabetes mellitus is associated with compromised cardiac function and accelerated atherosclerosis.
• Diabetic patients exhibit microvascular complications, including blindness, kidney failure, and peripheral gangrene.
• Inflammation plays a critical role in the pathophysiology of diabetes and its cardiovascular complications.

Purpose of the Study:

• To review predisposing factors and mechanisms of inflammation in diabetes.
• To assess current knowledge on triggers for inflammation in diabetic cardiovascular disease.
• To explore novel therapeutic strategies based on insights into diabetes and inflammation.

Main Methods:

• Comprehensive literature review of studies on diabetes, inflammation, and cardiovascular dysfunction.
• Evaluation of the roles of hyperglycemia, oxidative stress, and related pathways.
• Analysis of diabetic cardiomyopathy as a 'stem cell disease' and impaired coronary arteriole function.

Main Results:

• Diabetes leads to accelerated atherosclerosis and coronary microcirculatory dysfunction.
• Key factors include hyperglycemia, oxidative stress, advanced glycation end products, and inflammation.
• Diabetic cardiomyopathy involves complex mechanisms, potentially linked to stem cell dysfunction.

Conclusions:

• Inflammation is a crucial link between diabetes and cardiovascular complications.
• Understanding these mechanisms offers predictive and prognostic clinical utility.
• New insights may pave the way for innovative therapeutic interventions in diabetic cardiovascular disease.
