Особенности кардиореспираторных взаимоотношений при заболеваниях легких с обструктивным и рестриктивным типами нарушений вентиляции

We examined 239 patients suffering from various lung diseases with obstructive (84 patients) and restrictive (155 patients) ventilation disorders and 109 healthy persons. Cardiorespiratory interrelation according to echocardiography and spirography in patients with the lung function disorders differed from that in healthy and depended on a type and severity of the ventilation pathology. The relationship between the heart and the lungs became closer in the obstructive type as the ventilation failure progressing and it weakened in the restrictive type. Moreover, there were stable relationships between all the heart parts and ventilation parameters which were more marked for FVC and FEV 1 in obstructive patients. On the contrary, the restrictive patients demonstrated stable interrelation between heart parameters and flow volume parameters of middle and mostly small airways which occurred in moderate stage of the disease.
