RESUMO
Objective To investigate whether the combination of maintenance hemodialysis (MHD) with hemoperfusion (HP) could improve the left ventricular structure and function of MHD patients with resistant hypertension. Methods This study was a prospective, randomized, controlled clinical trial. 65 MHD patients with resistant hypertension of our hospital were enrolled and then randomly divided into Group HD+HP and Group HD. The follow-up study was 12 months. The major outcome measures were related to the cardiac structure and function, and the serum inflammatory factors. Results No statistical differences of related factors such as blood pressure and cardiac function was observed in HD group. The serum concentration of inflammatory factors was higher after one-year HD treatment alone. But the serum concentration of inflammatory related factors , blood pressure, cardiac function and related indexes were lower in HD + HP than in Group HD (P < 0.05);HD + HP group had higher ejection fraction (EF) and SV, which demonstrated the improved cardiac function (P < 0.05). Conclusions HD + HP was superior to HD in the treatment in alleviating cardiac after-load and improving the left ventricular structure and function of MHD patients with resistance hypertension.
