摘要

Objectives: The objective of this study was to highlight the correlations between ECG and echocardiographic changes with diagnostic role in right ventricular hypertrophy in patients with COPD GOLD stage II and III, as well as the correlations with respiratory functional impairment degree. Materials and methods: the study was conducted on a sample of 61 patients with COPD aged between 44 and 78 years old. Among them, 38 have been diagnosed with COPD GOLD stage II, and 23 with stage III. The patients underwent ECG and echocardiography with a view to detect any signs of right ventricular hypertrophy. Results: Patients with moderate and severe form of COPD often associate right ventricular hypertrophy on ultrasound, statistically uncorrelated with the degree of impaired respiratory function, but highlighting significant correlations of right ventricular hypertrophy with pulmonary artery systolic pressure (PASP) values. Electrocardiography shows a low sensitivity compared to echocardiographic method in the diagnosis of chronic cor pulmonale. Conclusions: The degree of respiratory functional impairment measured by maximum forced expiratory volume (FEV) in the first second, does not correlate with the risk of right ventricular hypertrophy. ECG method for the diagnosis of chronic cor pulmonale, although it is accessible, does not have a satisfactory sensitivity.
