Left ventricular function in patients with type 2 diabetes mellitus

Area of Science:

• Cardiology
• Endocrinology
• Medical Research

Background:

• Type 2 diabetes mellitus is a global health concern.
• Cardiac function in diabetic patients requires further investigation.
• Understanding sex-based differences in diabetic cardiovascular health is crucial.

Purpose of the Study:

• To compare cardiac structure and function between type 2 diabetes mellitus patients and non-diabetic controls.
• To investigate sex-specific differences in cardiac parameters in the context of diabetes.

Main Methods:

• Retrospective analysis of cardiac magnetic resonance imaging data.
• Comparison of left ventricular ejection fraction, end-diastolic volume, end-systolic volume, and muscle mass.
• Statistical analysis accounting for sex and diabetes status.

Main Results:

• Mean left ventricular ejection fraction, end-diastolic volume, end-systolic volume, and muscle mass were comparable between diabetic and non-diabetic groups.
• Abnormal ejection fraction was more common in men with diabetes than in men without diabetes.
• Women with diabetes did not show a higher prevalence of abnormal ejection fraction compared to women without diabetes.
• Women exhibited higher ejection fraction and lower volumes and muscle mass than men, irrespective of diabetes status.

Conclusions:

• While overall cardiac structure and function metrics are similar, diabetes impacts ejection fraction differently in men versus women.
• Sex is a significant factor in cardiac adaptations and potential dysfunction related to type 2 diabetes mellitus.
• Further research into sex-specific cardiovascular risks and management in type 2 diabetes is warranted.
