Study hypothesis

Chronic Heart Failure (CHF) represents a major public health burden, and its prognosis is comparable to that of different malignant diseases. CHF progresses because of the activation of neurohormones and pro-inflammatory cytokines, as well as coenzyme Q10 (CoQ) deficiency, following an initial cardiac injury such as Acute Myocardial Infarction (AMI), statin toxicity or a mutation of the genetic programme. It is becoming increasingly apparent that inflammatory mediators play a crucial role in the development of CHF and AMI and several strategies to counterbalance different aspects of the inflammatory response are considered. Possible targets involve pro-and anti-inflammatory cytokines and their receptors, endotoxin, adhesion molecules, nitric oxide and nitric oxide synthase, reactive oxygen species, CoQ and L-carnitine in mitochondria and different types of leucocytes.

The most important cytokines implicated in the progression of CHF are Tumour Necrosis Factor (TNF-alpha), Interleukin (IL)-1, and IL-6. These cytokines share some of their major characteristics (redundancy), and all act in a pro-inflammatory sense. Among those, TNF-alpha is the cytokine that has been studied in greatest detail. IL-10 is anti-inflammatory which is beneficial in heart failure. Cytokines form a vast array of relative low molecular weight, pharmacologically active proteins. These substances are secreted by different cell types for the purpose of altering either their own function (autocrine) or that of adjacent cells (paracrine). Several hypotheses have been suggested to describe the origin of immune activation in CHF. The production of pro-inflammatory cytokines has mostly been attributed to secretion by mononuclear cells, although the myocardium seems to be another important source. Some evidence suggests that catecholamines augment this myocardial cytokine production. There is evidence that CoQ and carnitine may be beneficial in patients with heart failure.

In the present study, we examine, that ubiquinol, in conjunction with L-carnitine, can decrease cytokines and may be useful in patients with CHF.

Patient information sheet


Chronic Heart Failure


Nine carni Q-gel softgels (three with each meal thrice daily), which provide a total of 270 mg ubiquinol and 2250 mg L-carnitine daily, or nine matching placebos were administerd to each patient, during the period of 12 weeks. All patients were kept on standard drug therapy, and carni Q-gel and placebo were used as adjuncts to regular drug therapy not as a replacement or substitute.

Laboratory data:
Baseline measurements were taken and repeated after 12 weeks, and a complete blood profile was performed including:
1. Thiobarbituric Acid Reactive Substances (TBARS) and Malondialdehyde (MDA) were obtained by colorimetric methods
2. Resting electrocardiogram and prothrombin time (on anticoagulants) were performed in all the patients at baseline and during follow up whenever indicated
3. CoQ levels in the serum were measured by high pressure liquid chromatography based on an earlier method at Tishcon Corporation (USA)
4. Cytokines Interleukin-six (IL-6), Interleukin-ten (IL-10) and Tumour Necrotising Factors (TNF)-alpha were determined by using a solid phase, two sided chemiluminescence enzyme immunometric assay (immulite automated analyser) kit

The serum samples were kept at -24°C until assay. Results were expressed in pg/ml. The technicians measuring the laboratory data were blind to the groups.
