Pulmonary hypertension (PH), regardless of its etiology, is associated with an impaired outcome in patients with chronic obstructive pulmonary disease (COPD). The aim of our study was to determine the incidence, cause, and effect of PH as detected by echocardiography in COPD patients. Patients with confirmed COPD of any stage were evaluated by echocardiography for the likelihood of PH according to the proposed criteria. Patients with possible/likely to have PH underwent right heart catheterization, upon agreement, to confirm the presence, severity, and cause of PH. Of 91 patients, 39 were in stable condition (group A) and 52 with COPD exacerbation (group B). Group B patients presented with PH and left ventricular diastolic dysfunction more often than group A patients. One of two fulfilled the criteria for possible/likely PH. The incidence of likely/possible PH was significantly higher in group B. Nineteen group B patients with likely/possible PH underwent RHC, and PH was confirmed in 15 cases and in 73.3% was associated with left heart disease. The presence of possible/likely PH was associated with a statistically significant increase in mortality compared to those with unlikely PH. The use of echocardiographic criteria for the presence of PH is adequate for the screening of COPD patients. Patients with acute exacerbation of COPD and possible/likely PH demonstrate worse mortality compared to patients unlikely to have PH. [Display omitted]
