Background: Patients with angina pectoris or myocardial infarction are more likely to experience stroke. Ischaemic stroke has been found to develop in approximately 2-5% of patients in the first 1- 2 weeks after myocardial infarction Methods: Fifty patients with coronary artery disease admitted to the National Institute of Cardiovascular Diseases (NICVD), Dhaka, were screened for presence of carotid atherosclerosis by duplex ultrasound study during the period of July 98 to August 98. Results: Carotid lesion were found in 34 patients (68%) and normal carotids found in 16 patients (32%). Age range of patients with and without carotid lesions was 56±5.39 yrs and 47±7.91 yrs respectively. Out of 34 patients, 30 were male (88.2%) and 4 were female (11.7%). 29 patients (85.3%) were smokers, 22 patients (64.7%) were hypertensive and 9 patients (26.4%) were diabetic. Dyslipidaemia was found in 16 patients (47%) and a history of transient ischaemic attack (TIA) was found in 10 patients (29.4%). A coexistent CAD on coronary (CAG) was found in 31 patients (91.1%). Conclusion: Cortaid duplex ultrasound study findings of atherosclerotic lesions in Carotid arteries are good predictors of CAD.Keywords: Carotid atherosclerosis, Carotid duplex ultrasound, Coronary artery disease.

Myocardial infarction with non-obstructive coronary artery disease (MINOCA) is a working diagnosis for patients presenting with acute myocardial infarction without obstructive coronary artery disease on coronary angiography. It is a heterogenous entity with a number of possible etiologies that can be determined through the use of appropriate diagnostic algorithms. Common causes of a MINOCA may include plaque disruption, spontaneous coronary artery dissection, coronary artery spasm, and coronary thromboembolism. Optical coherence tomography (OCT) is an intravascular imaging modality which allows the differentiation of coronary tissue morphological characteristics including the identification of thin cap fibroatheroma and the differentiation between plaque rupture or erosion, due to its high resolution. In this narrative review we will discuss the role of OCT in patients presenting with MINOCA. In this group of patients OCT has been shown to reveal abnormal findings in almost half of the cases. Moreover, combining OCT with cardiac magnetic resonance (CMR) was shown to allow the identification of most of the underlying mechanisms of MINOCA. Hence, it is recommended that both OCT and CMR can be used in patients with a working diagnosis of MINOCA. Well-designed prospective studies are needed in order to gain a better understanding of this condition and to provide optimal management while reducing morbidity and mortality in that subset patients.

Objective This study aimed to investigate whether differential expression of the retinoic acid receptor-related orphan receptor A ( RORA) gene is related to occurrence of acute myocardial infarction (AMI). Methods This was a retrospective study. White blood cells of 93 patients with acute myocardial infarction and 74 patients with stable coronary artery disease were collected. Reverse transcription quantitative polymerase chain reaction and western blotting were used to measure RORA mRNA and protein expression, respectively. Results RORA mRNA expression levels in peripheral blood leukocytes in patients with AMI were 1.57 times higher than those in patients with stable coronary artery disease. Protein RORA levels in peripheral blood of patients with AMI were increased. Binary logistic regression analysis showed that high expression of RORA was an independent risk factor for AMI, and it increased the risk of AMI by 2.990 times. Conclusion RORA expression levels in patients with AMI is significantly higher than that in patients with stable coronary artery disease. High expression of RORA is related to AMI and it may be an independent risk factor for AMI.
