Echocardiograph alterations in asthma patients

Abstract

Introduction: Asthma is a chronic inflammatory disease which has increased during the last 20 years, putting a strain on medical resources, particularly severe forms of the disease. Treatment in such cases is inhaled corticosteroids and beta agonist drugs that can produce a range of side effects. The aim of this study is to identify echocardiograph abnormalities and correlate them with severity of disease.

Methodology: Eight-seven outpatients were selected at the asthma unit of the Gaffrée Guinle University Hospital (HUGG). Each patient underwent spirometry, electrocardiogram (ECG) and echocardiogram (ECO) during the trial within a month maximum. Echocardiograph abnormalities found related to degree of asthma. Statistical analysis was made by nonparametric tests.

Results: We found significant differences (p<or=0.05) for age, disease duration and haemoglobin saturation (SaO2) between the moderate and severe groups. In the sample a high prevalence of tricuspid insufficiency (41.4%) was identified.

Conclusions: ECO identified a series of abnormalities that were not always dependent on severity of disease. ECO can identify pulmonary hypertension through calculation of mean pressure of the pulmonary artery.
