Noninvasive carotid duplex study may be used as predictor test for ischaemic heart disease.

A prospective observational study was carried out to detect carotid atherosclerosis using high resolution B-Mode in 150 in-hospital patients with clinically diagnosed ischemic heart disease in various forms in the department of Cardiology, University Cardiac Center, BSMMU, Bangladesh. The duration of study was from April 2006 to December 2008. Carotid Ultrasound evaluation was performed in 150 patients diagnosed as Ischemic Heart Disease by single operator (NF). Mean age of the patients was 53.62±10.92 with, male to female ratio of 9.5:0.5. Mean IMT was 0.96±0.21mm in 85% of the patient of clinically diagnosed IHD, which was higher than the normal (normal IMT ≤0.8mm). Among them, about 77% had atherosclerotic plaque. A significant correlation between Carotid atherosclerosis determined by IMT and Ischemic Heart Disease (IHD) was found. Non invasive carotid duplex study might be useful for predicting ischaemic heart disease.
