Echocardiographic changes of the left ventricle in bronchial asthma

In recent years, the attention of researchers has been increasingly attracted by the problem of multi- and comorbidity. The probability of developing combined diseases increases with an increase in life expectancy, which can be explained by both age-related changes and negative effects of the environment and living conditions for a long time. The increase in the number of diseases with age reflects, first of all, involutional processes, and the concept of comorbidity implies a deterministic the possibility of their combined flow, and the latter has been studied much less. And as a result, there is now an understanding that the problem the combination of diseases is difficult to overestimate, being one of the most difficult that doctors face. There are a number of well-known combinations, such as coronary heart disease (CHD) and diabetes mellitus, arterial hypertension (AH) and coronary heart disease, AH and obesity. But at the same time, there are increasingly indications of rarer combinations, for example, peptic ulcer and coronary heart disease, mitral stenosis and rheumatoid arthritis, peptic ulcer and bronchial asthma (BA). Bronchial asthma (BA) attracts the increased attention of specialists, which is associated with both a distinct increase in frequency, a heavier course of this disease, an increase in complications, and significant progress in its diagnosis and treatment. Epidemiological studies have shown that about 7 million people suffer from AD in the world, of which 1 million have a severe form of the disease. In recent years, more and more information has been accumulating that the study and evaluation of echocardiographic examination indicators can have an important diagnostic significance for understanding the pathogenesis of AD and predicting the development of complications from the cardiovascular system.
