Trial Outcomes & Findings for Metformin in Heart Failure Without Diabetes (NCT NCT03331861)

NCT ID: NCT03331861

Last Updated: 2024-07-18

Results Overview

The VO2 change outcomes will be assessed for normality using standard visual assessments (Q-Q plots and histograms) and statistical tests (Kolmogorov-Smirnov). VE/VCO2 slope change will be calculated.

PRIMARY outcome

Timeframe: Baseline and 6 months

Population: Study was terminated early; data was not collected due to low enrollment, thus cannot be analyzed.

The VO2 change outcomes will be assessed for normality using standard visual assessments (Q-Q plots and histograms) and statistical tests (Kolmogorov-Smirnov). VE/VCO2 slope change will be calculated.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Baseline and 6 months

Population: Study was terminated early; data was not collected due to low enrollment, thus cannot be analyzed.

Dyspnea Assessment. 100mm line scale ranging from 0 (worse imaginable breathing) to 100 (best imaginable breathing).

SECONDARY outcome

Timeframe: Baseline, 6 months

Population: Study was terminated early; data was not collected due to low enrollment, thus cannot be analyzed.

A validated patient-oriented measure of the adverse effects of heart failure on a patient's life. The questionnaire is comprised of 21 questions around several physical, emotional and socioeconomic ways heart failure can adversely affect a patient's life. After receiving brief standardized instructions, the patient marks a 0 (zero) to 5 (five) scale to indicate the extent to which each itemized adversity of heart failure has prevented the patient from living as they wanted to live during the past 4 weeks. The questionnaire is simply scored by summation of all 21 responses.

SECONDARY outcome

Timeframe: Baseline, 6 months

Population: Study was terminated early; data was not collected due to low enrollment, thus cannot be analyzed.

Oxygen consumption (VO2) (ml/min) will be measured on a breath by breath basis. Peak VO2 will be computed using standard methods.

SECONDARY outcome

Timeframe: Up to 6 months

Population: Study was terminated early; data was not collected due to low enrollment, thus cannot be analyzed.

The number of hospitalizations recorded during the study will be tallied.
