Epidemiology of the diabetic heart

Area of Science:

• Endocrinology and Metabolism
• Cardiology
• Public Health

Background:

• Diabetes mellitus represents a worldwide epidemic, with cardiovascular disease (CVD) as its primary complication causing significant morbidity and mortality.
• The elevated CVD risk associated with diabetes extends beyond diagnosed type I and type II cases to prediabetic states, including impaired fasting glucose, impaired glucose tolerance, metabolic syndrome, and obesity.
• A continuum of risk for CVD exists, progressing from insulin resistance and prediabetic conditions through to diagnosed diabetes mellitus.

Purpose of the Study:

• To highlight the substantial cardiovascular disease burden in the context of the global diabetes epidemic.
• To emphasize that the increased risk of cardiovascular events is not limited to overt diabetes but also present in prediabetic stages.
• To underscore the importance of preventive strategies targeting diabetes and its precursors for cardiovascular health.

Main Methods:

• Review of existing studies and evidence linking diabetes and prediabetic states to cardiovascular disease.
• Analysis of the progression from insulin resistance to diabetes and its association with cardiovascular risk.
• Examination of the prevalence of cardiac dysfunction in diabetic patients due to comorbidities.

Main Results:

• Cardiovascular disease is the leading cause of death and disability in individuals with diabetes mellitus.
• Prediabetic conditions such as impaired fasting glucose, impaired glucose tolerance, metabolic syndrome, and obesity are associated with increased cardiovascular disease risk.
• Diabetic patients exhibit a high incidence of heart failure and impaired cardiac function, often resulting from the interplay of coronary artery disease, hypertension, and diabetic cardiomyopathy.

Conclusions:

• The diabetes epidemic is intrinsically linked to a vast and growing proportion of cardiovascular disease mortality and morbidity.
• Preventing diabetes and its prediabetic stages is the most effective approach to mitigate serious cardiovascular events.
• Addressing the continuum of risk from insulin resistance through prediabetes to diabetes is essential for public health strategies aimed at reducing cardiovascular disease.
