Evaluation of systolic function of the right ventricle in patients with chronic obstructive pulmonary disease: a cross sectional study about 30 cases

Published on: 2020-03-30


Introduction: Chronic pulmonary heart is the main cardiovascular complication of chronic obstructive pulmonary disease. The aims of our study were to evaluate the right ventricular systolic function in patients with chronic obstructive pulmonary disease and to investigate the relationship between parameters of right ventricular function and pulmonary function testing data. Methodology: A multicenter cross-sectional study was conducted between January 2013 and July 2013 in cardiology and pulmonology department in Dakar. Was included all in or outpatient diagnosed for chronic obstructive pulmonary disease. Results: 30 patients were evaluated in this cohort. The mean age was 62.4 years. Male predominance was noted (sex ratio of 9). Right heart failure was found in 7 patients (23.3%). Right ventricule enlargement was noted in 12 patients (40%). Mean sPAP was 58.58 ± 23.59 mmHg. Pulmonary arterial hypertension was found in 16 (53.3%) patients. TAPSE was i the systolic pulmonary arterial pressure (sPAP) value greater than 60 mm Hg, as you choose as a cut-off for pulmonary hypertension mpaired in 7 patients (23.3%). Reduction of right ventricule fractional area change was present in 14 (46.6%) patients. S’ of the tricuspid annulus velocity was reduced in 11 (33%) patients. Parameters correlated with the severity of chronic obstructive pulmonary disease were: TAPSE (p= 0.0099), right ventricule fractional area change (p = 0.0095), S’ of the annular tricuspid (p= 0.0173) TEI index (p= 0.038) and Pulmonary arterial hypertension (p= 0,023). Conclusion: Evaluation of right ventricular systolic function in chronic obstructive pulmonary disease is fundamental and must use multiple parameters.
