An Exploratory Prospective Cohort Study on a Tailored Oral Glucose Loading Protocol for 18F-FDG PET Myocardial Metabolic Imaging in Diabetic Patients with Coronary Artery Disease
To evaluate the feasibility of a precise oral glucose loading combined with subcutaneous insulin administration protocol for 18F-FDG PET myocardial metabolic imaging in CAD patients with diabetes mellitus.
Approach:
Method: Study Population
Method: Imaging Protocol
Method: Image Quality Assessment
Key Findings:
FDG image quality was excellent in 57.5% of patients, with variations based on blood glucose levels.
Patients with blood glucose >7.77 mmol/L had significantly lower odds of excellent image quality.
26.3% of patients exhibited completely viable myocardium, while 49.7% had partially viable myocardium.
Interpretation:
The tailored oral glucose loading protocol is feasible for clinical application in this patient population.
Limitations:
The study was conducted at a single center, which may limit generalizability.
The sample size may not be sufficient to draw broader conclusions.
Conclusion:
The precise oral glucose loading protocol prior to 18F-FDG injection is feasible for clinical application.
A living clinical guideline outlines a treatment hierarchy for selected pharmacologic therapies in patients with obesity and selected patients with overweight.
