Safety and Efficacy of Long-Term Use of Tolvaptan in Patients With Heart Failure and Chronic Kidney Disease.

BACKGROUND

We assessed the long-term safety and efficacy of tolvaptan in 102 patients with heart failure (HF) and chronic kidney disease (CKD). Median follow-up duration was 1.6 years (1.0-4.4 years).Methods and Results:One patient discontinued tolvaptan because of hypernatremia. There were no changes in renal function or electrolytes during the 1-year follow-up. The cardiac-related death-free or HF-related hospitalization-free survival rate was significantly higher in patients receiving tolvaptan than in propensity score-matched patients who did not receive tolvaptan.

CONCLUSIONS

In patients with HF and CKD, long-term administration of tolvaptan was well-tolerated, relatively safe and effective, suggesting its utility for long-term management of these conditions.
