This study investigated the dose-related effect of losartan on changes in renal function using data from the HEAAL (Heart failure Endpoint evaluation of Angiotensin II Antagonist Losartan) trial.


Angiotensin receptor blockers adversely affect renal function in patients with heart failure (HF). The time course and dose dependency of this time course, as well as the clinical implications of these changes in renal function, are not well described.


Subjects in the HEAAL dataset (n = 3,843) were studied. Changes in estimated glomerular filtration rate (eGFR) over time were compared between dose groups. The association between the timing of incident increases in serum creatinine (SCr) >0.3 mg/dl and clinical outcomes was explored.


Compared with 50 mg, 150 mg losartan led to a greater reduction in eGFR across time (mean difference:-3.76 ml/min/1.73 m(2); p < 0.0001). This difference was driven by early changes, and differences in eGFRafter 4 months were not significant (mean difference: 0.42 ml/min/1.73 m(2); p = 0.15) [corrected]. Although an increase in SCr >0.3 mg/dl from baseline was associated with increased risk of death or hospitalization for HF (hazard ratio [HR]: 1.36; p < 0.0001), the relationship was not significant if the change occurred before 4 months (HR: 1.09; p = 0.20). Despite increased risk of worsening renal function, 150 mg losartan was associated with reduced risk of death or hospitalization for HF compared with 50 mg (HR: 0.85; p < 0.0001).


Compared with 50 mg, 150 mg losartan is associated with an increased risk of acute rise in SCr, as well as with greater long-term reductions in eGFR. Despite these effects, high-dose losartan retains its net clinical benefit and is associated with reduced risk of death or hospitalization for HF.
