Left ventricular echocardiographic abnormalities by conventional echocardiography and tissue doppler image in chronic obstructive pulmonary diseases patients

Abstract

Objective: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. It leads to deleterious effects on heart, cor pulmonale, and congestive heart failure that are a major cause of morbidity and mortality. Early diagnosis and treatment can mitigate the ill effects of COPD and lead to better patient management and improve the morbidity data. Echocardiography provides a rapid, noninvasive, portable, accurate method to evaluate cardiac functions, early diagnoses, and intervention for cardiac comorbidities can reduce mortalities in COPD patients. The aim of this study is to find echocardiographic changes in COPD patients and correlated with disease severity. Materials and Methods: Eighty-two patients of COPD fulfilling the inclusion criteria coming to outpatients of Margan medical city were recruited. They were staged by pulmonary function test and evaluated by echocardiography. Statistical analysis of correlation was done with Chi-square test and ANOVA test and the statistical significance was taken P< 0.05. Results: The most common echocardiographic finding was left ventricular diastolic dysfunction (LVDD), which was present in 64.6% of cases, the prevalence increase with increase the severity of disease; other echocardiographic findings were pulmonary hypertension, the total prevalence was 53.7% and also the prevalence increase by increase severity. LV diastolic function affected significantly with severity of COPD. Conclusions: Echocardiography should be considered in the assessment of patients with clinically significant COPD.
