Abstract:
Objective To evaluate the prevalence and potential risk factors for pulmonary hypertension in the elderly hospitalized patients. Methods1093 elderly hospitalized patients aged (80.8 ± 9.8) years were examined by Doppler echocardiography for evaluating pulmonary hypertension which defined by pulmonary artery systolic pressure (PASP)≥40 mm Hg (1 mm Hg=0.133 kPa).The relative clinical testing data were collected. Results 115 patients (10.5％) of the elderly patients were diagnosed as pulmonary hypertension.The prevalence of pulmonary hypertension in patients aged 85-100 years was 16.4％ (82/500),which was higher than in other ages. In the multivariate logistic regression analysis,age (OR=1.085,95％CI=1.025-1.148,P=0.005),left ventricular diastolic dysfunction (OR =3.954,95 ％ CI =1.812-8.627,P=0.001 ),internal diameter of right ventricle (OR=1.271,95％CI=1.112-1.452,P=0.000) and internal diameter of left atrium (OR=1.100,95％CI=1.013-1.194,P=0.023) were risk factors for pulmonary hypertension.ConclusionsThe prevalence of pulmonary hypertension is high in the elderly hospitalized patients,especially those aged 85 years and over,complicated with left ventricular diastolic dysfunction and enlargement of right ventricle and left atrium.
