Abstract	Objective. To investigate the correlation between respiratory failure and the pulmonary circulation. We focused on anatomical and functional changes of the right heart. Design. Clinical investigation. Methods. We evaluated 75 patients hospitalized in our respiratory ward for COPD exacerbation. All patients underwent transthoracic echocardiography and measurements of right heart chambers. Moreover all patients underwent blood tests, measurement of blood pressure, evaluation of body mass index (BMI), ECGs, pulmonary function tests, and the Saint George's Respiratory Questionnaire (SGRQ). Results. Among 75 patients consecutively hospitalized, 56 patients with a COPD exacerbation were included in our study. We have emphasized the higher value of PAPs and the increased size of right atrial area in severe COPD patients. Significant correlation was observed between low values of PaO2 and larger area of the right atrium. The measurement of TAPSE showed a right ventricular dysfunction in all patients but especially in severe COPD patients. We have obtained a significant correlation between TAPSE and arterial blood gas. Conclusions. In patients with chronic respiratory failure, blood gas parameters should be considered as negative prognostic factors of right heart failure. Respiratory failure shows a relationship with pulmonary hypertension and with the anatomy and function of the right heart sections.
