Hypervetilation syndrome as a risk factor of diastolic dysfunction among hypertension patients

Abstract

Hypertensive disease is one of the urgent problems in the modern cardiology. It is known that a huge variety of comorbid states influence the development of hypertensive disease, i. e. neurogenic hyperventilating syndrome. It is the sign and the marker of suprasegmental vegetative structures disorders that destabilize homeostasis, initiate the development of specific pathological processes, which are the base of somatization of hyperventilating disorders, including heart disorders. It led to research of structural and functional characteristics of the ventricles with the help of echocardiology among hypertensive patients with neurogenic hyperventilating syndrome. Ventricular dilation of cavities, mostly of the right one without thickening of the walls, was found in the patients with stage 1 hypertension disease (43.59 %). Dilation of the ventricular cavities was also revealed in hypertensive patients with stage 2 hypertension disease in 37.88% of cases. The next variations of remodeling were registered: concentric – in 10.61% of cases; concentric hypertrophy – in 22.73%; asymmetric hypertrophy – in 12.12%; eccentric remodeling and eccentric hypertrophy of the left ventricle – in 4.55% and 9.09% of patients, respectively. Thickening of the right ventricle wall was observed in 13.64% of patients. In the control group of patients without hypertonic syndrome, the signs of concentric and asymmetric hypertrophy were noticed in 10% of patients, eccentric – in 20%; extension of the left ventricle – in 20%. The assessment of the condition of transmitral and tricuspid flows revealed a significant increase in the number of cases, disorders, relaxation of the heart ventricles among hypertensive patients with neurogenic hyperventilating syndrome. It can be a sign of specific role of permanent hyperventilation in ventricle remodeling and mandatory systematic echocardiological control of these patients.
