Objective A relationship with GA of calcified plaque in diabetic dalysis patient' carotid artery ultrasound test Methods Three carotid artery ultrasound tests were performed on 92 diabetic patients receiving dialysis (53 men, 39 women) and 86 non-diabetic patients receiving dialysis (47 men, 39 women) with six month intervals between tests. During each exam, IMT thickness was measured and the appearance of calcified plaques was noted. In 13 patients (7 diabetics and 6 non-diabetics), calcified plaques were observed during the third exam after the first two exams showed no evidence of calcified plaques. The thickness of the calcified plaques was measured (the sum of both sides). Over the course of a year, these 13 patients were examined every month and the percentage of HbA1c-NGSP value, GA percent, HDL, LDL, non-HDL, blood pressure immediately before dialysis, weight gain between dialysis procedures, Na, K, Ca2+, HS-PTH, P, CaP product, Alp and ß2MG were measured. Results A newly appeared thickness of the calcified plaque (sum of the total value of right and left sides) correlation was accepted by the GA(%) and following formula. y =0.0902x + 1.203 P = 0.0298 R = 0.601 Conclusion In the diabetic dialysis patient, the blood sugar control standards had not been detemined, but from the calcification of vascular appearance of this time, blood sugar control was considered necessary.
