Cardiovascular disease in diabetes type 2: current concepts.

Area of Science:

• Endocrinology and Public Health

Background:

• Type 2 diabetes has seen a dramatic global increase from 108 to 422 million adults between 1980 and 2014.
• Prevalence has doubled in men (4.3% to 9.0%) and increased in women (5.0% to 7.9%), with significant rises in low- and middle-income countries.
• Type 2 diabetes is increasingly recognized as heterogeneous, with cardiovascular disease risk varying by phenotype, age, and complications.

Purpose of the Study:

• To analyze the global trends and public health impact of type 2 diabetes.
• To investigate the heterogeneity of cardiovascular disease risk in type 2 diabetes.
• To highlight the need for more research in low- and middle-income countries.

Main Methods:

• Analysis of global diabetes prevalence data from 1980-2014.
• Review of existing research on cardiovascular disease risk factors and outcomes in type 2 diabetes.
• Examination of the influence of factors like obesity, age, glycaemic control, and renal complications.

Main Results:

• Global adult diabetes cases rose to 422 million by 2014, driven by obesity, population growth, and longevity.
• Low- and middle-income countries show the most significant increases, with rates surpassing high-income nations.
• Cardiovascular disease risk in type 2 diabetes is not uniform, with heart failure emerging as a key concern linked to poor glycaemic control and obesity.

Conclusions:

• Type 2 diabetes represents an accelerating global health challenge, particularly in lower-income nations.
• Understanding diabetes heterogeneity is crucial for accurate cardiovascular risk assessment and personalized treatment.
• Further research, especially in underrepresented regions, is essential to improve management and outcomes for type 2 diabetes patients.
