Outcome Measures
Primary Outcomes (2)
Quality of Life (QoL) measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) (at the end of ozone therapy)
Self-reported evaluation of 21 physical, emotional and socioeconomic ways heart failure can adversely affect a patient's life. Each item is scored from 0 (no affected) to 5 (very much affected). Total range from 0 (best) to 105 (worst)
16 weeks
Direct Hospital Cost (at the end of ozone therapy)
The direct expenses incurred by the hospital in providing services (medication, tests, medical visits...) during the 16 weeks of ozone therapy (in euros).
16 weeks
Secondary Outcomes (30)
Change from Baseline in quality of life by the "5-level, 5-dimension EuroQol" (EQ-5D-5L) questionnaire (at the end of ozone therapy)
16 weeks
Change from Baseline in quality of life by the "Short Form 36-item health survey" (SF-36) questionnaire (at the end of ozone therapy)
16 weeks
Change from Baseline in Montreal Cognitive Assessment (MOCA) questionnaire (at the end of ozone therapy)
16 weeks
Change from Baseline in Biochemical cardiac parameters (High sensitive troponin, pro-brain natriuretic peptide (proBNP)) (at the end of ozone therapy)
16 weeks
Change from Baseline in Biochemical parameters of oxidative stress (at the end of ozone therapy)
16 weeks
- +25 more secondary outcomes
Study Arms (2)
Ozone Group:
EXPERIMENTALStandard treatment + Ozone therapy (O3/O2)
Control Group:
PLACEBO COMPARATORStandard treatment + Oxygen (O2)
Interventions
Ozone Group: Standard treatment + Ozone therapy (O3/O2) by rectal insufflation. O3/O2 concentration progressively increased from 10 to 30 µg/ml; 40 sessions in 16 weeks.
Control Group: Standard treatment + Oxygen (O2) by rectal insufflation. O3/O2 concentration = 0 µg/ml (only O2); 40 sessions in 16 weeks.
