Abstract

Background Although 25% to 44% of patients with heart failure (HF) have diabetes mellitus (DM), the optimal treatment regimen for HF patients with DM is uncertain. We investigated the association between metformin therapy and outcomes in a cohort of advanced, systolic HF patients with DM.Methods and results Patients with DM and advanced, systolic HF (n = 401) were followed at a single university HF center between 1994 and 2008. The cohort was divided into 2 groups based on the presence or absence of metformin therapy. The cohort had a mean age of 56 +/- 11 years, left ventricular ejection fraction (LVEF) of 24 +/- 7%, with 42% being New York Heart Association (NYHA) III and 45% NYHA IV. Twenty-five percent (n = 99) were treated with metformin therapy. The groups treated and not treated with metformin were similar in terms of age, sex, baseline LVEF, medical history, and baseline glycosylated hemoglobin. Metformin-treated patients had a higher body mass index, lower creatinine, and were less often on insulin. One-year survival in metformin-treated and non-metformin-treated patients was 91% and 76%, respectively (RR = 0.37, CI 0.18-0.76, P = .007). After multivariate adjustment for demographics, cardiac function, renal function, and HF medications, metformin therapy was associated with a nonsignificant trend for improved survival.Conclusion In patients with DM and advanced, systolic HF who are closely monitored, metformin therapy appears to be safe. Prospective studies are needed to determine whether metformin can improve HF outcome.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In patients with diabetes mellitus and advanced systolic heart failure, one-year survival in metformin-treated and non-metformin-treated patients was 91% and 76%, respectively (p=0.007).

    “One-year survival in metformin-treated and non-metformin-treated patients was 91% and 76%, respectively (p = 0.007).”
  • After multivariate adjustment, metformin therapy was associated with a non-significant trend of improved survival in patients with diabetes mellitus and advanced systolic heart failure.

    “After a multivariate adjustment for demographics, cardiac function, renal function, and HF medications, metformin therapy was associated with a non-significant trend of improved survival [85].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
