Hypertension is common in patients with chronic kidney disease. Whether blood pressure management before dialysis initiation influences prognosis during maintenance dialysis remains unclear. Hence, we surveyed the status of antihypertensive drug use in incident dialysis patients. Moreover, we examined the association between antihypertensive drug use patterns at the time of dialysis initiation and mortality. We used a database derived from the multicenter prospective Aichi Cohort Study of Prognosis in Patients Newly Initiated into Dialysis, which included 1520 incident dialysis patients in Aichi prefecture, Japan. The baseline in the present study was set as the time of dialysis initiation. We examined antihypertensive drug prescription patterns at baseline, as well as the association between use of antihypertensive drugs and mortality after dialysis initiation. Among all participants, 1440 were taking at least one antihypertensive drug. The rate of calcium channel blocker (CCB) use was highest, accounting for 74.3%. CCB use was significantly associated with lower all-cause and cardiovascular-related mortality (hazard ratio [HR]: 0.62 and 0.57, 95% confidence interval [CI]: 0.46–0.85 and [0.35–0.91], respectively). Compared with no use of either drug, combination therapy with a renin angiotensin system blocker (RASB) and CCB was significantly associated with lower mortality (HR: 0.51, 95% CI: 0.34–0.76). The present study demonstrated that antihypertensive drugs were used in 95% of incident dialysis patients. In addition, use of a CCB and combination therapy with a CCB and RASB at the time of dialysis initiation was associated with lower mortality during maintenance dialysis.
