Abstract/OtherAbstract:
Cardiovascular complications are encountered frequently in end-stage renal disease (ESRD) patients. The study was designed as a prospective cohort study and a total of 105 dialysis patients, 77 hemodialysis and 28 peritoneal dialysis patients, were investigated. All patients had undergone M-Mode Doppler echocardiography every 6 months by which their systolic pulmonary arterial pressures (sPAPs) and left ventricular mass indices (LVMIs) were recorded. Thirty-nine (37.1%) patients had pulmonary hypertension (PHT), that is, a mean sPAP of more than 35 mmHg. The frequency of PHT was higher in peritoneal dialysis patients but the difference was insignificant (p = 0.08). However, the frequency of left ventricular hypertrophy (LVH) was found to be significantly higher in peritoneal dialysis patients than in hemodialysis patients (p = 0.001). When patients with and without PHT were compared, the duration of dialysis (p = 0.02), hemoglobin (p = 0.01), HbA1c (p = 0.03), and serum albumin levels (p = 0.003) were found to be significantly higher in patients with PHT than those without PHT. In conclusion, although nonsignificant, we found a higher prevalence of PHT in peritoneal dialysis patients when compared with hemodialysis patients. This might be due to the significantly higher prevalence of LVH, hence hypervolemia, in peritoneal dialysis patients. The prevention and treatment of PHT in dialysis patients is very important for the improvement of survival in these patients. Hence, the increased prevalence of PHT in ESRD patients necessitates understanding the multiple and interacting factors, such as LVH, serum albumin and hemoglobin levels, and control of diabetes, that might contribute to this pathology in these patients.
