Abstract
The article describes the current algorithms of diagnostics of inherited (dysplasia) of connective tissue (DCD) that are currently in force in the territory of the Russian Federation, compared in terms of identification of morpho-functional cha racteristics of heart. Describes the shortcomings of these algorithms do not take into account the gender features of the prevalence of signs. According to the algorithm, developed by experts of Russian Society of Cardiology (RSC), highlight dysplastic phenotypes, most of which is now a marfanoid habitus (MH). Revision of the diagnostic algorithm, which takes into account the specificity of individual MH bone signs and their gender dimensions. It is proved that for young people with MH is characterized by increased frequency of cardiac anomalias (atrial Septal aneurysm, the functional asymmetry of the aortic valve), identified structural features heart-relative myocardial hypertrophy of the left ventricle, increasing the diameter of the aorta. The features of heart rate in patients with MH – relative tachycardia during daylight hours, reducing the symptoms of sinus arrhythmia, decreased heart rate variability power spectral. It is shown that for boys with MH is characterized by lengthening the electrical systole (QT interval), 21.4% of cases greater than 480 Ms. At the same time, the DCD diagnostic algorithm that is described in the recommendations of the Russian Scientific Society of therapists (RSSIM leads to over diagnosis this condition in young age does not allow to identify the structural and functional features of the heart and could not be recommended for practical use.
