Background: Carotid intima-media thickness (CIMT) refers to the measurement of the thickness of the inner two layers of the carotid artery wall—the intima and the media. The present study was conducted to assess relation between coronary angiographic findings and carotid intima-media thickness. Materials &Methods: 72 patients with stable angina pectoris of both genderswere divided into 2 groups of 36 each. In group I, patients were without a noncritical coronary lesion, and in group II, patients were having at least one lesion more than 50% within the main branches of the coronary arteries. All of the patients underwent carotid doppler ultrasound examination for measurement of the CIMT. Results: Smoking was present in 54% in group I and 67% in group II and hyperlipidemia was seen in 18% in group I and 56% in group II, diabetes was present in 50% in group I and 61% in group II and hypertension was seen in 36% in group I and 47% in group II. The difference was significant (P< 0.05). The mean carotid artery thickness in group I was 0.76 mm and in group II was 1.8 mm. The difference was significant (P< 0.05). The major risk factors for coronary artery diseasewas CIMT (>1 mm) (P- 0.02) and hypertension (P- 0.05). Conclusion: Increase in CIMT was associated with the presence and extent of coronary artery disease.
