Classification, Diagnosis, and Treatment of Obesity-Related Heart Diseases

Area of Science:

• Cardiology
• Metabolic Disorders
• Preventive Medicine

Background:

• Obesity is a major risk factor for cardiovascular (CV) diseases, including cardiomyopathy, heart failure, atrial fibrillation, and sudden cardiac death.
• Obesity can alter cardiac structure and function, leading to subclinical cardiac dysfunction and overt heart failure.
• Early detection of obesity-related heart disease is crucial for preventing adverse CV events.

Purpose of the Study:

• To explore the complex relationship between obesity and cardiovascular disease (CVD) outcomes.
• To investigate the phenomenon known as the "obesity paradox" in CVD.
• To identify better predictors of CVD risk in obese individuals beyond body mass index (BMI).

Main Methods:

• Review of evidence-based medicine linking obesity to cardiovascular diseases.
• Analysis of diagnostic methods for early detection of obesity-related heart disease.
• Examination of studies on the "obesity paradox" and its implications.
• Evaluation of alternative indicators like waist-to-hip ratio, ectopic body fat, and cardiovascular fitness for risk stratification.

Main Results:

• Obesity is strongly associated with increased risks of various cardiovascular diseases and adverse events.
• The "obesity paradox" suggests that BMI alone is insufficient to predict clinical outcomes in CVD.
• Indicators such as waist-to-hip ratio, ectopic fat, and CV fitness can differentiate CV risk in individuals with similar BMIs.

Conclusions:

• A multidisciplinary approach is essential for managing cardiovascular health in overweight and obese patients.
• Personalized risk assessment using indicators beyond BMI is crucial for effective early intervention.
• Lifestyle modification, pharmacotherapy, and surgical interventions can improve CV outcomes in this population.
