Cardiovascular function in young patients with type 1 diabetes mellitus

Area of Science:

• Cardiology
• Diabetology
• Medical Imaging

Background:

• Type 1 diabetes mellitus (T1DM) is associated with cardiovascular complications.
• Early detection of cardiac dysfunction in T1DM is crucial for management.

Purpose of the Study:

• To assess echocardiographic cardiovascular function in T1DM patients.
• To compare cardiac parameters between T1DM patients and healthy controls.
• To investigate correlations between left ventricular mass, contractility, and clinical parameters in T1DM.

Main Methods:

• Echocardiography was performed on 47 T1DM patients and 30 healthy controls.
• Indexed left ventricular mass, stroke volume, cardiac output, cardiac index, and contractility were calculated.
• Statistical analysis was used to compare groups and identify correlations.

Main Results:

• Left ventricular mass and performance were slightly elevated in T1DM patients, with borderline significance for cardiac output (p=0.06).
• Left ventricular mass correlated significantly with stroke volume, cardiac index, blood pressure, and contractility in T1DM patients.
• Left ventricular contractility was independently associated with indexed systolic and diastolic blood pressure in T1DM.

Conclusions:

• T1DM patients exhibit subtle alterations in left ventricular mass and performance.
• Blood pressure and contractility are key determinants of left ventricular mass in T1DM.
• Further research is needed to explore the impact of diabetes duration on cardiac function.
