Gemodinamik buzilishlarga birlamchi moslashuv bosqichida tug‘ma yurak nuqsonlarining klinik kechi

The article presents the results of a clinical and instrumental study of the course of congenital heart disease (CHD) in young children during the phase of primary adaptation to hemodynamic disturbances. A total of 159 children with CHD from birth to 3 years of age were examined, with assessment of clinical manifestations, central hemodynamic parameters, and echocardiographic indices. The most common manifestations were weakness, dyspnea, palpitations, and gastrointestinal disturbances. Children with CHD demonstrated tachycardia, increased pulse pressure, and age-related increases in indexed left ventricular volumes, while left ventricular ejection fraction remained relatively preserved. The findings indicate activation of compensatory mechanisms and progressive cardiac volume overload and support comprehensive monitoring of hemodynamic and nutritional status from early infancy.
