Résumé
Background: Pulmonary artery hypertension (PAH) is the most common cause of right heart failure and right ventricular dysfunction(RVD). Portopulmoanry hypertension (POPH) is a form of pulmonary arterial hypertension (PAH) associated with portal hypertension with or without underlying chronic liver disease leading to right venricular dysfunction. The aim of this study is to evaluate prevalence of right ventricular dysfunction and its association with pulmonary artery hypertension, body mass index(BMI), systemic hypertension and smoking. Material and methods: This is a cross-sectional observation study, it was conducted on 84 patients with portal hypertension. Trans-thoracic echocardiography was done for calculation of PASP (pulmonary artery systolic pressure) and TAPSE(tricuspid annulus plane systolic excursion), TDI( tissue doppler imaging) S’ for RVD. Observation: Prevalence of RVD was was 14.28%%, in male it was 15.6% and female it was 20.0%. Sex was insignificant in RVD with p value of 0.74. Mean age of POPH patients were 53.33+ 8.3 year, age was insignificant with p-value 0.86. BMI,hypertension and PAH was found significant in RVD patients with p- value of 0.01, 0.008 and 0.0001 respectively. Smoking was insignificant (P-0.971). Conclusion:There is association of right ventricular dysfunction with pulmonary hypertension in portal hypertensive patients.
