  Purpose
The aim of this study was to investigate whether carotid IMT can predict the presence of more advanced atherosclerosis such as carotid stenosis, coronary or intracranial artery disease by MDCT and whether MDCT could be useful next step for more aggressive treatment modality in Korean type 2 diabetic patients.

Condition
Type 2 Diabetes

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Cross-Sectional
Official Title: Association of Carotid IMT and Large-vessel Atherosclerosis by MDCT in Korean Type 2 Diabetic Patients

Primary Outcome Measures:
  • We compared prevalence of large artery stenosis according to carotid IMT group and evaluated whether maximal IMT ≥ 1.0 mm could predict for significant CAD by MDCT. [ Time Frame: 17 months ]

Secondary Outcome Measures:
  • We performed invasive coronary angiography in some patients (N=14) and analyzed association for degrees of CAD between two angiographic methods. [ Time Frame: 17 months ]

Enrollment: 71
Study Start Date: April 2006
Study Completion Date: July 2007
Groups/Cohorts
Carrotid IMT group according to maximal IMT
We defined increased IMT group as whom had maximal IMT ≥ 1.0 mm.

Detailed Description:
We evaluated mean/maximal carotid IMT in seventy-one type 2 diabetic subjects, and defined increased carotid IMT as maximal IMT ≥ 1.0 mm. Multidetector CT (MDCT) and pulse wave velocity (PWV) were taken to evaluate carotid artery stenosis (CS), coronary artery disease (CAD), intracranial arterial lesion (ICA), and peripheral artery disease (PAD). We compared prevalence of large artery stenosis according to carotid IMT group and evaluated whether maximal IMT ≥ 1.0 mm could predict for significant CAD by MDCT. We performed invasive coronary angiography in some patients (N=14) and analyzed association for degrees of CAD between two angiographic methods.
