Abstract: Изобретение относится к медицине, а именно к сосудистой хирургии, и может быть использовано для прогнозирования опасности эмбологенного разрыва нестабильной каротидной атеросклеротической бляшки. Осуществляют построение модели бифуркации сонной артерии и оценку касательного напряжения ее стенки. При этом дополнительно выполняют компьютерную ангиографию и модель бифуркации сонной артерии строят по ее результатам. Оценку касательного напряжения стенки сонной артерии осуществляют с учетом давления крови на выходе из зоны ее атеросклеротического поражения и одновременно определяют нормальное напряжение стенки сонной артерии с учетом изменений артериального давления крови внутри ее просвета. Определяют векторные величины касательного и нормального давления на стенку артерии. После этого проводят сложение их значений, характеризующих величину показателя полного напряжения сосудистой стенки в зоне атеросклеротической бляшки при различных значениях системного артериального давления. При достижении их суммы, равной или превышающей 17,8 кПА при показателях системного артериального давления 160 мм рт.ст. и ниже считают опасность разрыва нестабильной атеросклеротической бляшки крайне высокой, что является показанием к оперативному вмешательству. Способ обеспечивает прогнозирование опасности эмбологенного разрыва нестабильной каротидной атеросклеротической бляшки и своевременное выполнение оперативного вмешательства за счет определения диагностического критерия - показателя полного напряжения сосудистой стенки в зоне атеросклеротической бляшки. 3 ил., 1 пр.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to clinical medicine, particularly to rheumatology, cardiology, therapy. A set of diagnostic parameters is determined: age of first system lupus erythematosus (SLE) (x1) symptoms appearance, SLE duration at examination (x2), duration of nephritis (x3), heredity of cardiovascular diseases (x4), presence of smoking (x5), presence of arterial hypertension (x6), level of cholesterol (x7), value of atherogenicity index (x8). Based on the obtained data, each indicator is assigned a certain score and an integral index of a prediction of the risk of developing atherosclerotic involvement of carotid arteries with underlying SLE (P) is calculated by formula: P=6.598×x1+1.179×x2+0.855×x3+1.985× x4+0.066×x5+0.910×x6+1.058×x7+0.243×x8. Where: x1 is assigned "0 points", if the age of the first symptoms of SLE is less than 40 years, "1 point" - if 40 years and more; x2 is assigned "0 points" if the SLE duration is less than 12 months, "1 point" - if 12 months and more; x3 is assigned "0 points", if the nephritis duration is less than 24 months or there is no nephritis, "1 point" - if 24 months and more; x4 is assigned "0 points" if heredity in cardiovascular diseases is not burdened, "1 point" - heredity burdened; x5 is assigned "0 points" if the patient does not smoke, "1 point" - if smoked; x6 is assigned with "0 points", if there is no arterial hypertension, "1 point" - in the presence of arterial hypertension; x7 is assigned with "0 points", if cholesterol level is less than 5 mmol/l, "1 point" - if 5 mmol/l and more. If P is "4.5 or less", a low risk of developing atherosclerotic plaques is predicted in the patients with SLE. If P "from 4.6 to 5.5", a moderate risk is predicted; if P "from 5.6 to 7.0", a high risk is predicted; if P "from 7.1 and higher", a very high risk is predicted. 
     EFFECT: method enables more accurate prediction of the risk of developing atherosclerotic plaques in patients with SLE, provided fewer diagnostic indicators are determined, which is achieved by taking into account a diagnostically significant set of diagnostic indicators.
