Abstract

Background: There are few data to demonstrate the feasibility of long- term blood pressure (BP) control using short dialysis sessions as practiced in the US. Control of hypertension in hemodialysis patients may reduce the risk of cardiovascular events. Methods: Forty-two dialysis patients had BPs and weights recorded before and after dialysis for two consecutive weeks and were followed by one physician over three years. Patients were treated by ultrafiltration and conventional antihypertensive drugs and BPs were repeated at three years in the 32 survivors. Results: 93% of the patients (39/42) were African-American. At inception, 85% of the patients were hypertensive with BPs of 154 ± 23/83 ± 14 mmHg and 137 ± 22/74 ± 14 mmHg pre- and post- dialysis, respectively. The response to ultrafiltration was dependent upon gender, with women having a greater BP reduction compared to men. At three- year follow-up, the BP had dropped significantly in the survivors a mean of 9.4/6.7 mmHg. Pre-and post-dialysis weights, post dialysis BP and interdialytic weight-gain were unchanged. The BP reduction was achieved by an increase in the number of antihypertensive medications from 0.91 ± 0.86 medications to 1.41 ± 1.16. Improved BP control did not worsen the efficiency of dialysis (Kt/V). The use of β-blockers doubled during the period of follow-up. Compared to the USRDS average cardiovascular death rate, the risk of cardiovascular deaths was improved 80% over three years. Conclusion: Long-term BP reduction can be achieved through the use of antihypertensive agents and volume control in a predominantly African- American hemodialysis population. This may impact cardiovascular mortality.
