Hypothesis
Can myocardial T1 mapping detect abnormalities in type 2 diabetic patients with normal heart function?
Conclusion
T1 relaxation time is decreased in asymptomatic type 2 diabetic patients with normal ejection fraction, indicating potential early heart issues.
Supporting Evidence
- Diabetic patients showed decreased global circumferential strain compared to volunteers.
- Mean myocardial T1 relaxation time was significantly shorter in diabetic patients at both 5 and 15 minutes after gadolinium injection.
- Echocardiography revealed abnormal diastolic LV filling in 55% of diabetic patients.
Takeaway
Doctors can use a special MRI technique to find heart problems in people with diabetes even before they feel sick.
Methodology
Type 2 diabetic patients were compared to healthy volunteers using T1 mapping and echocardiography.
Participant Demographics
24 diabetic patients (average age 51) and 16 matched healthy volunteers (average age 47).
