Insulin resistance--the new goal!

Area of Science:

• Cardiology
• Endocrinology
• Public Health

Background:

• Diabetes mellitus is a major risk factor for coronary artery disease (CAD), increasing risk two to sixfold.
• The global prevalence of diabetes is rising, with a 30% increase in the UK since 1991.
• CAD mortality has declined in non-diabetics but remains unchanged or increased in diabetic men and women, respectively.

Purpose of the Study:

• To review the concept of insulin resistance (IR) in the context of cardiovascular disease.
• To explore potential interventions for managing IR and its associated cardiovascular risks.
• To highlight the challenges in improving macrovascular outcomes in diabetic patients despite good glycemic control.

Main Methods:

• Review of epidemiological studies on diabetes and CAD risk.
• Analysis of trends in CAD mortality in diabetic versus non-diabetic populations.
• Examination of the role of insulin resistance (IR) and associated abnormalities in cardiovascular disease development.

Main Results:

• Good diabetic control improves microvascular complications but not macrovascular ones.
• Insulin resistance (IR) is linked to abnormalities that may cause cardiovascular disease.
• Current approaches include tighter glycemic control, hypertension management, and targeting the prediabetic state.

Conclusions:

• Improved diabetic control does not guarantee better macrovascular outcomes.
• Insulin resistance (IR) presents a critical area for intervention in cardiovascular disease prevention.
• Further research and novel strategies are needed to address the cardiovascular burden in diabetes.
