Cardiovascular outcomes in type 1 and type 2 diabetes

Area of Science:

• Cardiology
• Endocrinology
• Public Health

Background:

• Diabetes mellitus is a global cardiometabolic health crisis.
• Type 1 diabetes, though less common (~2%), has early onset and long-term implications.
• Cardiovascular disease (CVD) and premature mortality are major outcomes for both type 1 and type 2 diabetes.

Purpose of the Study:

• To investigate the comparative CVD risk between type 1 and type 2 diabetes.
• To identify key factors influencing CVD risk in different diabetes types.
• To inform strategies for diabetes management and CVD prevention.

Main Methods:

• The study is a comprehensive review and analysis of existing literature on diabetes and CVD.
• It examines epidemiological data, risk factor associations, and clinical outcomes.
• Comparative analysis focuses on modifiable and non-modifiable risk factors.

Main Results:

• Type 2 diabetes prevalence is increasing, significantly impacting global health.
• CVD risk is influenced by both general cardiovascular factors (LDL cholesterol, hypertension, smoking) and diabetes-specific factors (HbA1c, albuminuria).
• Younger individuals with type 1 diabetes may face higher long-term CVD risk due to cumulative glucose exposure, despite declining CVD rates.

Conclusions:

• Effective diabetes management requires a focus on absolute and lifetime CVD risk.
• Life-long glycaemic control, lipid and hypertension management, and smoking cessation are paramount for prevention.
• A combination of healthy lifestyle, pharmacological therapy, and addressing individual risk factors is essential.
