Abstract | BACKGROUND: METHODS: One hundred and forty-four MHD patients with hypertension were enrolled in this perspective, randomized, controlled, single-center trial. All patients accepted antihypertensive drugs at baseline, including renin-angiotensin system inhibitor, calcium channel blocker, ß-receptor blocker or a-receptor blocker. Seventy-two patients ( nitrate group) took isosorbide mononitrate 30 mg daily, titered to a maximal dosage of 120 mg daily for 24 weeks. The dosage was adjusted once a week according to BP. The remaining 72 patients (non- nitrate group) did not take nitrate drugs other than antihypertensive drugs. BP, left ventricular mass index (LVMI), heart rate, interdialytic weight gain (IDWG) and hemoglobin (Hb) were monitored. RESULTS: After 4, 8, 12 and 24 weeks of treatment, BP levels decreased in both nitrate and non- nitrate groups. BP in the nitrate group was significantly lower than in the non- nitrate group. But there was no statistical significance in the levels of response rate and control rate of BP between the 2 groups (response rate of BP: 91.4% vs. 86.1%, X2=1.004, p=0.316; control rate of BP: 60.0% vs. 47.2%, X2=2.230, p=0.127). BP before hemodialysis was maintained between 12 and 24 weeks in the nitrate group despite the decrease in total daily category and quantity of hypotensive drugs. At week 24 of treatment, LVMI in the nitrate group was significantly decreased from 65.3 ± 14.2 g/m2.7 to 51.2 ± 10.0 g/m2.7, and that in the non- nitrate group was also significantly decreased from 63.7 ± 16.7 g/m2.7 to 56.1 ± 13.8 g/m2.7. But LVMI in the nitrate group was significantly lower than that in the non- nitrate group. The prevalence of LVH in the nitrate and non- nitrate groups decreased 17.2% and 9.8%, respectively. There was a significant difference in both groups at 24 weeks (X2=4.480, p=0.034). During 24 weeks of follow-up, the incidence of acute left heart failure in the nitrate group was 1.4% (1/70), which was significantly lower than in the non- nitrate group (11.1%, 8/72; X2=5.605, p=0.033). The incidence of adverse events was 1.4%. CONCLUSIONS:
