Особенности сердечно-сосудистого ремоделирования у пациентов с аневризмой восходящего отдела аорты

Abstract

Background: Diagnosis of aortic aneurism and its complications are studied, but factors associated with uncomplicated aortic aneurysm, “markers” of progressive or stable course of aortic aneurysms remain a contentious issue of Cardiology. The presence of an aortic aneurysm may contribute to the emergence of new or exacerbate existing structural-functional disorders of the heart. It is important to determine the characteristics of cardiovascular remodeling in patients of all ages diagnosed with an aneurysm of the ascending aorta. Material and methods: The study involved 154 patients, with the expansion of the root and / or the ascending aorta 40 mm by echocardiography. The patients were divided according to age WHO classification (1963): 18-29 years, 30-44 years, 45-59 years, 60-74 years. Results: Aneurismal aortic enlargement and a certain dilatation of the heart cavities in 1-the second group was due to some extent defective connective tissue structures and the weakness of connective tissue skeleton heart and aorta. Starting from the 2nd group increased myocardial mass and left ventricular wall thickness, increased relative wall thickness. This is due to the increase of the share of GB and coronary artery disease. There is a tendency to a decrease in ejection fraction in elderly patients. Conclusions: Cardiovascular remodeling in patients with aneurysm of the ascending aorta is due not only to heart disease, but also age. The expansion of the root often caused connective tissue dysplasia,and the extension of the distal ascending aorta is mainly associated with atherosclerosis or hypertension. In young patients, the expansion of the aortic root is more commonly associated with cardiodilatation without a significant increase in left ventricular mass and maintaining its contractile function. Patients of older age groups revealed mainly dilatation of the ascending aorta, as associated with left ventricular hypertrophy, and with a tendency to a decrease in left ventricular function. The results allow the use of location data localization of aortic enlargement to determine its cause.
