To the diagnosis of pre-disease in smokers

Smoking is a risk factor for many diseases. In particular, it leads to the development of chronic bronchitis and its complications. However, in spite of the urgency of the research of cardiorespiratory system state in smokers, there are almost no data in the literature about the complex study of this system in this contingent. The aim of this work is to elucidate the mechanisms of early changes in the cardiorespiratory system and to develop methods for their diagnostics in smokers who consider themselves healthy. 325 smokers and 197 non-smokers were examined. Their medical history was studied, ECG, fluoro- and spirography (GEL, SPHF, Votchal-Tiffno index) were performed. Smokers considered themselves healthy, they did not have any complaints.
