Key result
Gray-scale and Doppler ultrasound revealed increased carotid artery tunica intima media thickening in 80% and atheromatous plaque in 66% of patients with stable ischemic heart disease.
Why the study?
Coronary heart disease remains a major cause of global morbidity and mortality, prompting evaluation of gray-scale ultrasound and carotid artery Doppler for risk stratification in stable ischemic heart disease.
What is the role of gray-scale and Doppler ultrasound of the carotid artery in risk stratification and assessing plaque morphology in patients with stable ischemic heart disease?

What is the role of gray-scale and Doppler ultrasound of the carotid artery in risk stratification and assessing plaque morphology in patients with stable ischemic heart disease?
Carotid ultrasound demonstrates a high prevalence of increased intima-media thickness and atheromatous plaques in patients with stable ischemic heart disease, supporting its utility in risk stratification.

Introduction: Coronary heart disease (CHD) is a major cause of mortality and morbidity all over the world. According to a report of World Health Organization (WHO) in 2005, cardiovascular disease (CVD) caused 17.5 million (30%) of the 58 million deaths that occurred worldwide. While the prevalence and mortality due to CHD is declining in the developed nations the same cannot be held true for developing countries. Aims And Objective: This study aimed to establish the role of Gray Scale USG and carotid artery Doppler study as a leading investigation in general population presenting with Stable Ischemic Heart Disease. It intended to evaluate the frequency and degree of carotid artery stenosis in these patients & also assess the morphology of atherosclerotic plaque and IMT which are clearly related to pathogenesis and aid in planning and management. Materials And Methods: Adult persons attending to Nilratan Sircar Medical College & Hospital, Kolkata both at OPD and Ward, with Stable Ischemic Heart disease that has undergone coronary angiography were chosen as the Study population. Result And Analysis: Our study showed that 62 % of the patients were above 60 years of age. 84 % of our patients were male.74% of our patients had history of smoking. 70 % of our patients had type 2 diabetes mellitus. 72 % of our patients were dyslipidemic. 78% of the patients were hypertensive. 80 % of patients had increased carotid artery tunica intima media thickening. 66 % of patients had presence of atheromatous plaque in carotid arteries. Summary And Conclusion: However, our study did corroborate with the other available studies except for few deviations like increased number of modiable risk factors in our group. Our study clearly demonstrated Metabolic syndrome –X as a strong risk factor for ischemic heart disease and also suggested early medical treatment can prevent future recurrence. Larger multicentric trials may be necessary in future, for further validation

Banerjee et al. (2021) conducted an observational in Stable Ischemic Heart Disease. Gray-scale and Doppler ultrasound of carotid artery was evaluated on Frequency and degree of carotid artery stenosis, morphology of atherosclerotic plaque and IMT. Gray-scale and Doppler ultrasound revealed increased carotid artery tunica intima media thickening in 80% and atheromatous plaque in 66% of patients with stable ischemic heart disease.
