Abstract

BACKGROUND: Patients with chronic heart failure (HF) secondary to left ventricular systolic dysfunction (LVSD) are frequently deficient in vitamin D. Low vitamin D levels are associated with a worse prognosis. OBJECTIVES: The VINDICATE (VitamIN D treatIng patients with Chronic heArT failurE) study was undertaken to establish safety and efficacy of high-dose 25 (OH) vitamin D3 (cholecalciferol) supplementation in patients with chronic HF due to LVSD. METHODS: We enrolled 229 patients (179 men) with chronic HF due to LVSD and vitamin D deficiency (cholecalciferol <50 nmol/l [<20 ng/ml]). Participants were allocated to 1 year of vitamin D3 supplementation (4,000 IU [100 μg] daily) or matching non-calcium-based placebo. The primary endpoint was change in 6-minute walk distance between baseline and 12 months. Secondary endpoints included change in LV ejection fraction at 1 year, and safety measures of renal function and serum calcium concentration assessed every 3 months. RESULTS: One year of high-dose vitamin D3 supplementation did not improve 6-min walk distance at 1 year, but was associated with a significant improvement in cardiac function (LV ejection fraction +6.07% [95% confidence interval (CI): 3.20 to 8.95; p < 0.0001]); and a reversal of LV remodeling (LV end diastolic diameter -2.49 mm [95% CI: -4.09 to -0.90; p = 0.002] and LV end systolic diameter -2.09 mm [95% CI: -4.11 to -0.06 p = 0.043]). CONCLUSIONS: One year of 100 μg daily vitamin D3 supplementation does not improve 6-min walk distance but has beneficial effects on LV structure and function in patients on contemporary optimal medical therapy. Further studies are necessary to determine whether these translate to improvements in outcomes. (VitamIN D Treating patIents With Chronic heArT failurE [VINDICATE]; NCT01619891).

  • The low sensitivity of NYHA classification and 6 min walk test limits their ability to measure change over time.

    “The low sensitivity of NYHA classification and 6 min walk test limits their ability to measure change over time”

    From Prioritizing symptom management in the treatment of chronic heart failure (2020) · cites this paper as [38]

    The Discussion (page not provided) says six-minute walk distance had greater variability than expected, leaving the trial underpowered to detect a clinically relevant change. This supports a limitation of the 6-minute walk test in detecting change in this trial. The Results list baseline NYHA classes but do not assess the classification’s sensitivity to change over time.

    From Prioritizing symptom management in the treatment of chronic heart failure (2020) · cites this paper as [38]

    The Methods > Study procedures section describes a six-minute walk test, echocardiography, and cardiac MRI, but not cardiopulmonary exercise testing. Searches for metabolic gas exchange equipment and limits on the applicability of cardiopulmonary exercise testing found no passage addressing the claim. Page numbers are unavailable in our copy.

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.
