The specialities of functional condition of heart-vescular system among the schoolchildren with endemic goiter in republic North-Ossetia
Objective: the investigation of thyroid body and haemodynamic characteristics among seniors, living in North-Ossetia Republic. Features and methods: 288 pupils in age of 15 to 17 were examined. We investigated the levels of thyroid-stimulating hormone, free thyroxin, haemodynamic characteristics with the help of expert class hypersonic scanner “Vivid 7 dimeshion” (GE). Results: almost among all pupils was revealed euthyroid condition. The level of TTH hesitated from 0,5 to 2,3 mkMe/ml, didn’t exceeded the normal indexes; the numbers of freeT4 and T3 didn’t exceeded normal indexes (11,8 - 21,2 pmole/l 1,7 - 2,7 nmole/l). Average indexes of morphometric heart indicators, including sizes of heart cavities (EDVLV, ESSLV, ESVLV, EDSLV), thickness index of heart paries (TBPLV, TBBB), retractive ability of myocard (EF, MV) left ventricle were normal among all patients. Striking volume of LV increased not authentically (68,2 ml in comparison with examining group 63,8 ml) remained in normal limits. MV heart indexes, EF and contraction factions were increased without exceeding age indexes in groups with iodine deficit in comparison with examining group. In all two groups were revealed the attributes of connectingtela heart dysplasia. The frequency of mitral seal prolapse was authentically higher in experiment group. In less cases prolapse was holding with an expansion of mitral seal ring and regurgitation of 1 level. The prolapse of tricuspid seal of 1 level with regurgitation of 1 level were observed by far rarely in examining group, but was intense in group with endemic goiter. Conclusion: The necessity of holding prophylactic procedures to hold the correction of available dismicroelements was proved.
