Summary
Diabetic heart disease can be detected early using systolic time intervals (STI). Strict blood sugar control improves left ventricular function in diabetic patients, highlighting the importance of metabolic management.
Area of Science:
- Cardiology
- Diabetology
- Internal Medicine
Background:
- Diabetes mellitus is associated with cardiovascular complications.
- Subclinical left ventricular dysfunction may precede overt cardiac symptoms in diabetic patients.
Purpose of the Study:
- To evaluate left ventricular function in diabetic patients without cardiac symptoms using systolic time intervals (STI).
- To investigate the relationship between metabolic control, microangiopathy, and myocardial involvement in diabetes.
Main Methods:
- Systolic time intervals (STI) were assessed in 45 diabetic patients.
- Patients were evaluated for cardiac signs, symptoms, metabolic control, and microangiopathy (kidney and retina).
Main Results:
- STI parameters indicated impaired left ventricular function, suggesting preclinical myocardial involvement.
- Left ventricular dysfunction was more pronounced in patients with poor metabolic control and microangiopathy.
- Improved STI parameters were observed with good metabolic control.
Conclusions:
- Diabetes can lead to preclinical myocardial disease due to metabolic and vascular factors.
- Strict metabolic control is crucial for improving left ventricular function and managing diabetic cardiomyopathy.
