40 cases of myocardial infarction and carotid atherosclerosis in relation


8o% of them underwent coronary angiography. Distribution of myocardial infarction: a simple 1O cases inferior wall infarction, inferior wall complicated by right ventricular infarction in 3 cases, 2 cases of inferoposterior infarction, the former asked the wall infarction l3 cases, extensive anterior wall infarction in 5 cases, combined high lateral wall of the former asked infarction 7 cases. 1.2 Methods coronary angiography: The Siemens angiography, using JucllJwPs method, taking the level of posteroanterior, left and right front oblique, feet, head position projection. The existence of any branch of coronary artery> 50% stenosis as there is disease. Carotid artery ultrasound, applied the United States ATL-3000 7MHz frequency ultrasonic diagnostic probe detection, patient was supine head back position, tend to check the opposite side, were used to detect twin carotid artery,[link widoczny dla zalogowanych], carotid bifurcation at the internal carotid artery, testing include: arterial diameter, medial thickness,[link widoczny dla zalogowanych], plaque location, shape,[link widoczny dla zalogowanych], size and echo characteristics, estimated luminal stenosis. Check the appropriate attention to the process of adjusting the instrument gain, image brightness and contrast, to obtain the best images using an image magnification device in order to facilitate the identification and the endothelium: improving the accuracy of measured values. 2 results medial thickening> 1.2rran as plaque formation, according to the echo characteristics into a flat spot, hard plaque, soft plaque and plaque ulceration. 4o cases of myocardial infarction in this group were detected in patients with carotid artery 80 carotid artery 80. The results according to instructions. (1) coronary angiography showed single vessel lesions, carotid artery ultrasound abnormal rate of 10%. One common carotid artery with normal carotid artery in 2 cases, endometrial thickening slightly in 2 cases, bilateral common carotid artery bifurcation plaques (hard spots) in 3 cases, the start of unilateral internal carotid artery and total artery bifurcation plaques seen in 2 cases. (2), double vessel coronary artery disease by angiography, carotid artery ultrasound abnormal rate of about 35%. Which pre artery with normal carotid artery in 2 cases, endometrial thickening slightly in 2 cases. Flat middle carotid artery bifurcation of common carotid artery plaque morphea in 8 cases. Carotid artery bifurcation and adjacent parts of hard plaque and two carotid artery plaque in 4 cases. (3) coronary angiography showed three lesions. Carotid artery ultrasound abnormalities was 70%. One common carotid artery in 1 case smooth and no plaque, common carotid artery bifurcation of common carotid artery plaques were visible lO many cases, common carotid artery bifurcation of carotid artery plaque at the combined 5 cases. (4) coronary angiography showed four lesions, carotid artery ultrasound abnormalities was 95%. Carotid artery bifurcation of carotid artery plaque can be seen at almost all. 40 patients with carotid artery diameter stenosis was not serious. Only 4 cases there are limits stenosis (56% a 75%),[link widoczny dla zalogowanych], other narrow objects <3o% or normal. 3 Atherosclerosis is a discussion of systemic disease, a common pathogenesis of coronary and carotid cable will produce the same results b】. Recently found that carotid artery and coronary artery close links between, and independent factors for predicting coronary heart disease. Our results show that: common carotid artery atherosclerotic plaque predilection sites in the bifurcation is most common, and often both sides involved. Followed by the start of the internal carotid artery. The more the number of coronary vessel disease, the site appears more widely, if the bilateral internal carotid artery at the bifurcation of carotid artery plaque, and plaque area were larger for the coronary angiography revealed double vessel can be these lesions.
