AIMS: Loop diuretics have become a mainstay of chronic heart failure management. Furosemide and torsemide are the two most common loop diuretics; nevertheless, there is inconsistent evidence regarding the optimal choice of loop diuretic with respect to clinical outcomes.
METHODS: Medline and Cochrane Databases were systemically reviewed for randomized and observational studies comparing patients with chronic heart failure on oral torsemide versus oral furosemide and their association with intermediate-term outcomes (5-12 months) through May 2018. Odds ratios with corresponding 95% confidence intervals (CIs) were used for outcomes. A random effect model was used to account for heterogeneity among studies. Heterogeneity was assessed with the Higgins I-square statistic.
RESULTS: A total of 8127 patients were included in the analysis from a total of 14 studies (10 randomized, four observational); 5729 patients were prescribed furosemide and 2398 were given torsemide. There was no significant difference in intermediate-term mortality among heart failure patients on furosemide compared with torsemide [odds ratio (OR) 1.01, CI 0.64-1.59, I = 65.8%]; however, furosemide was associated with an increased risk of heart failure readmissions (OR 2.16, CI 1.28-2.64, I = 0.0%). Heart failure patients taking torsemide were more likely to have an improvement in New York Heart Association class compared with those on furosemide (OR 0.73, CI 0.58-0.93, I = 19.6%).
CONCLUSION: Torsemide is associated with a reduction in intermediate-term heart failure readmissions and improvement in New York Heart Association class compared with furosemide but is not associated with a reduced mortality risk. Additional randomized trials are needed to examine the impact of loop diuretics on clinical outcomes in patients with heart failure.
