Background: In hemodialysis, hypertension is treated by removing excess fluid and antihypertensive therapy. Commonly, the antihypertensives used to treat hypertension in earlier stages of kidney disease are continued as the patient progresses into end-stage renal disease and begins dialysis, without much evidence for benefit. Methods: This study is a single center, retrospective chart review that included hemodialysis patients admitted for congestive heart failure (CHF), fluid overload, or pulmonary edema as determined by ICD-9 code (428.x, 276.6, 518.4, 506.1). The primary objective was to determine if the number or class of antihypertensives used in the chronic hemodialysis population increased the number of readmissions related to CHF, fluid overload, or pulmonary edema. Patients were separated into two groups based on total number of antihypertensive medications, less than or equal to 2 medications for group 1 and greater than two medications for group 2. The primary endpoint was 30-day readmission for CHF, fluid overload, or pulmonary edema. Results: For the study period, 85 individual patient charts met inclusion criteria. Group 1 (n = 44) experienced seven readmissions (16%) and group 2 (n = 41) experienced eight readmissions (18%) (p = 0.663). The most common antihypertensives at discharge were ACE inhibitors for group 1 (45%) and dihydropyridine calcium channel blockers for group 2 (66%). No difference in systolic blood pressures before, during and after hemodialysis was found between groups. Conclusions: Antihypertensive medications continue to play an important role in the hemodialysis population. This study suggests that drug class and quantity of antihypertensives do not alter readmission rate in the setting of fluid overload.
