چکیده انگلیسی

ObjectivesThe aim of this study was to determine the prevalence of exercise-induced pulmonary hypertension (EIPH) in consecutive subjects referred for stress echocardiography for chest pain or shortness of breath and correlate echocardiographic diagnosis of EIPH with hemodynamics at right heart catheterization (RHC).BackgroundElevated pulmonary pressure can lead to significant morbidity and mortality. EIPH by ehocardiography has been described in patients with connective tissue disease. It's prevalence in the setting of routine clinically indicated stress echocardiography unknown.MethodsIn a retrospective analysis of 4068 consecutive stress subjects undergoing stress echocardiography, 479 subjects with EIPH were identified. All 479 subjects with EIPH were compared to 479 age and sex matched subjects with normal pulmonary artery pressures post exercise. EIPH was defined as PASP > 50 mm Hg or peak tricuspid regurgitation velocity > 3.2 m/s. Of 100 patients with EIPH who underwent RHC we identified variables which predicted abnormal hemodynamic findings on RHC.ResultsThe prevalence of EIPH in subjects referred for stress echocardiography was 11.7%. A greater proportion of subjects with EIPH were obese or had lung disease or connective tissue disease. Of 100 subjects who underwent RHC, 65 had abnormal results. Age > 55 years (OR 5.1, p < 0.01]) or dilated left atrium (OR 4.4, p = 0.02]) were independently associated with abnormal right heart hemodynamics.ConclusionsThe results demonstrate that 11.7% of patients undergoing clinically indicated stress echocardiography have EIPH. Of those who underwent RHC abnormal hemodynamics were significantly associated with a dilated left atrium or age older than 55 years.
