Abstract

BACKGROUND: The GUIDE-IT (GUIDing Evidence Based Therapy Using Biomarker Intensified Treatment in Heart Failure) trial prospectively compared the efficacy of an N-terminal pro-B-type natriuretic peptide (NT-proBNP)-guided heart failure treatment strategy (target NT-proBNP level < 1,000 pg/ml) with optimal medical therapy alone in high-risk patients with heart failure and reduced ejection fraction. When the study was stopped for futility, 894 patients had been enrolled.

OBJECTIVES: The purpose of this study was to assess treatment-related quality-of-life (QOL) and economic outcomes in the GUIDE-IT trial.

METHODS: The authors prospectively collected a battery of QOL instruments at baseline and 3, 6, 12, and 24 months post-randomization (collection rates 90% to 99% of those eligible). The principal pre-specified QOL measures were the Kansas City Cardiomyopathy Questionnaire (KCCQ) Overall Summary Score and the Duke Activity Status Index (DASI). Cost data were collected for 735 (97%) U.S.

RESULTS: Baseline variables were well balanced in the 446 patients randomized to the NT-proBNP-guided therapy and 448 to usual care. Both the KCCQ and the DASI improved over the first 6 months, but no evidence was found for a strategy-related difference (mean difference [biomarker-guided - usual care] at 24 months of follow-up 2.0 for DASI [95% confidence interval (CI): -1.3 to 5.3] and 1.1 for KCCQ [95% CI: -3.7 to 5.9]). Total winsorized costs averaged $5,919 higher in the biomarker-guided strategy (95% CI: -$1,795, +$13,602) over 15-month median follow-up.

CONCLUSIONS: A strategy of NT-proBNP-guided HF therapy had higher total costs and was not more effective than usual care in improving QOL outcomes in patients with heart failure and a reduced ejection fraction.
