In type 2 diabetic patients, carotid intima-media thickness progresses in the vast majority, with diastolic blood pressure, peripheral arterial disease, and low HDL identified as key predictors of progression and plaque formation.
CIMT progression in most T2DM patients should not yet change practice; leaves open whether targeting DBP, PAD, or HDL alters outcomes.
In order to assess the progression of carotid-artery disease in type 2 diabetic cohort (n=207 patients), the dynamic change in carotid intima-media thickness (CIMT) and the occurrence of plaques were followed for a period of 31.35±10.59 months. The mean CIMT at the beginning of the study was 0.9178±0.1447 mm, with a maximal value of 1.1210±0.2366 mm. The maximal value of CIMT changed by 0.07 mm/year. Progression of CIMT was noted in 86.8% and its regression in 7.8% of patients. The occurrence of carotid plaques was detected in 41.8% of patients. Multiple regression analysis revealed the maximal value of CIMT to be associated with diastolic blood pressure, despite mean CIMT being predicted by body mass index. The presence of peripheral arterial disease and hypo-high-density lipoproteinemia were found to be predictors for the occurrence of carotid plaques. Our data have clinical implications in predicting risk factors for the progression of carotid-artery disease in type 2 diabetic patients for their appropriate management.
