Abstract
Background: chronic obstructive pulmonary disease (COPD) is a common cause of morbidity and mortality. Cardiovascular disease is a significant cause of morbidity and mortality in COPD.
Aim: The aim of this study was to evaluate cardiac function by echocardiography in chronic obstructive pulmonary disease patient and its co-relation with the severity of the disease.
Patients and methods: prospective study was conducted on 60 stable COPD patients, who presented at Abbasia chest hospital during the period from November 2016 till august 2017.
Spirometry was performed for all participants according to American Thoracic Society/European thoracic society (2005). They were classified according to GOLD guidelines (2017) and evaluated by 2D-Doppler echocardiography according to American Society of Echocardiography/European Association of Echocardiography ASE recommendations
Results: Echocardiographic examination of left ventricular functions revealed no cases of LVSD but LVDD was found in about 25%.
RV dilatation was found in about 18% of patients. Tricuspid regurge was in about 75% with variable grades from mild to severe. Pulmonary hypertension (PH) was in about 40% of patients. It was more prevalent in patients with severe and very severe disease. Correlation between echo findings and severity of COPD revealed significant positive correlation only with RV size, tricuspid regurgitation and pulmonary hypertension.
Conclusion: LVDD appears to be frequent in COPD patients but it is not related to the disease severity. Right heart abnormalities could be anticipated. Prevalence of PH has a linear relationship with severity of COPD
