Abstract:
Primary (essential) hypertension in children and adolescents is an important condition because it represents an independent risk factor for cardiovascular disease – left ventricular hypertrophy. The study included 54 patients with essential hypertension (42 boys and 12 girls), aged from 10 to 17 years, and the control group which consisted of 22 normotensive patients. All children underwent diagnostic examinations – ECG, Echocardiography and Cardiointervalography based on the unified technique. The study results showed predominance of enhanced tonus of the vegetative nervous system (51.9% of cases) and hyper-active sympathetic nervous system response in 56.6% of participants. These findings confirm the impact of the autonomic nervous system dysfunction on the development of hypertrophy of the left ventricle.
Hipertensiunea arterială esenţială la copii şi adolescenţi prezintă actualitate datorită factorului de risc cardiovascular independent - hipertrofia ventriculară stângă. Studiul dat a înclus 54 de pacienţi cu HTAE (42 băieţi şi 12 fete) cu vîrsta 10-17 ani şi un grup de control -22 de pacienţi normotensivi. A fost efectuată:ECG, EcoCG şi CIG după metode unificate recunoscute. Studiul a determinat predominanţa tonusului vegetativ simpaticotonic în51.9% şi a reacţiei vegetative hipersimpaticotonice în 56.6% cazuri, fapt ce poate confirma contribuţia DNV la formarea HVS.
