We studied 60 cases (45 diabetics and 15 normal volunteers as control).
For all cases: complete medical history and examination was done, fasting
blood sugar, post prandial blood sugar, lipid profile , resting E.C.G, fundoscopy,
fluorescence angiography, and D.E.T. in a dose of 0.84 mg/Kg
SW in 10 minutes by i.v. infusion were done. Diabetic patients were classified
into three groups according to their fundus status (No retinopathy,
with background retinopathy, or with proliferative retinopathy). DET was
negative in all diabetics with normal fundus while it was positive in 20%
of diabetics with background retinopathy and in 66.7% of diabetics with
proliferative retinopathy. Diabetics with positive DET had significant
higher triglycerides and cholesterol (P< 0.01) and longer duration of diabetes
(P <0.01), while no significant difference in either SW or BMI (P>
0.05). We conclude that DET could be considered as a simple screening test
for diabetics with silent CAD for the early diagnosis and management of
this condition. Routine fundoscopy will be a helpful tool to select the cases
which have the priority to be tested by DET. |
