Abstract Pulmonary hypertension is a hemodynamic and pathophysiological state found in a range of clinical conditions and is characterized by increase in mean pulmonary arterial pressure (mPAP >35 mmHg). The purpose of the study was to study pulmonary artery pressure among patients with chronic renal failure. The study was a prospective study including 30 cases admitted to Ain Shams university hospital with end stage renal disease. All patients were subjected to Transthoracic Doppler Echocardiography for assessment of pulmonary artery pressure (PAP). In the present study Among 30 patients with chronic renal failure 16 patients had pulmonary hypertension while 14 had normal RVSP with mean pulmonary arterial systolic pressure (PASP) was 41±12.4 mmHg with range from 20 to 75 mmhg There was significant correlation between sex and pulmonary hypertension that is more common in males than females while no significant correlation between age and RVSP among studied population. There was no significant correlation between anemia and RVSP among studied population.There was significant correlation between HTN and RVSP, and no significant correlation between DM and RVSP among studied population. The current study showed significant correlation between duration of dialysis and pulmonary hypertension. There was highly significant correlation between dialysis shunt and pulmonary hypertension. from the present study it was concluded that: This study demonstrated a high prevalence of pulmonary hypertension among patients with ESRD on regular hemodialysis, especially in males, longer duration of dialysis treatment, systemic hypertension, AV fistula.. |
