|August 5, 2008
Summary
Ribose supplementation improved exercise capacity in advanced heart failure patients. This study found that d-ribose enhanced ventilation at the anaerobic threshold, improving overall physical function in patients with congestive heart failure.
Area of Science:
- Cardiology
- Metabolic Medicine
- Exercise Physiology
Background:
- Advanced heart failure is characterized by exercise intolerance, potentially linked to reduced cellular energy levels in the myocardium.
- Current pharmaceutical treatments do not directly address cellular energy deficits in heart failure.
- Energy-enhancing substrates have shown variable efficacy, but ribose has demonstrated potential in restoring myocardial energy and improving cardiac function post-ischemia.
Purpose of the Study:
- To investigate the effect of d-ribose on ventilation at the anaerobic threshold in patients with congestive heart failure (CHF).
- To assess if ribose supplementation can improve exercise performance and ventilatory efficiency in advanced heart failure.
Main Methods:
- A study involving 16 patients with NYHA class III-IV heart failure.
- Patients received d-ribose (5 gms, three times daily) for 8 weeks.
- Evaluated parameters included VO(2), tidal volume/VCO(2), and heart rate/tidal volume at the anaerobic threshold.
Main Results:
- Significant improvements were observed in ventilatory parameters at the anaerobic threshold for all patients.
- A notable 44% improvement in Weber class was recorded.
- Ribose supplementation positively impacted the ventilatory exercise status in patients with advanced heart failure.
Conclusions:
- D-ribose supplementation can enhance ventilatory function and exercise capacity in patients suffering from advanced heart failure.
- Ribose represents a potential therapeutic strategy to address cellular energy deficits and improve exercise intolerance in CHF.

Heart Failure VI: Adjunct Therapies
Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.
Heart Failure Drugs: Inotropic Agents
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
Heart Failure V: Medical Management
Medical Management of Acute Decompensated Heart Failure (ADHF)The primary goals of therapy for patients hospitalized with acute decompensated heart failure (ADHF) include:Relieving symptomsOptimizing volume statusSupporting oxygenation and ventilationMaintaining cardiac output (CO) and end-organ perfusionIdentifying and addressing the cause of ADHFPreventing complicationsProviding patient education on factors precipitating HF exacerbationPlanning for dischargeOngoing monitoring and assessment...
Heart Failure II: Pathophysiology
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
Ischemic Heart Disease: Overview
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...

Heart Failure I: Introduction
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...
