Chronic obstructive lung disease and ischaemic heart disease: some aspects of functional diagnostics

Abstract

The aim of the study was an analyze of literal and some own data on a diagnostic problem of COPD in ischaemic heart disease (IHD) patients.

An assessment of diagnostic value of respiratory function examination, bicycle test, electrocardiography Holter's daily monitoring, electrocardiogram telemetry, and echocardiography was performed in 1554 patients with COPD accompanied by IHD. It was revealed that the most informative diagnostic method for ischaemic disorders in such patients is the dynamic electrocardiogram daily monitoring, especially in patients with severe ventilation disorders. A prevalence of combined arrhythmias and aberrations of ventricular complex on superventricular arrythymias was recorded and thought to follow atrial-and-ventricular dyssynergy or ventricular asynergy. It was found that the earliest phenomena of intracardiac haemodynamic disorders in combined COPD and IHD patients were left atrium dysfunction and dilatation.

We suppose that a prognosis of the combined pathology generally depends on the left heart contractility. Beta-blokers caused a significant loss in the respiratory function and a formation of the pathologic syndrome of airways early expiratory closure. A correction of management of both the diseases consists of the early COPD and IHD diagnostics taking into account the interrelated features of cardiorespiratory functional status.
