Effective and safe therapy with coenzyme Q10 for cardiomyopathy

Summary Coenzyme Q₁₀ (CoQ₁₀) is indispensable in mitochondrial bioenergetics and for human life to exist. 88/115 patients completed a trial of therapy with CoQ₁₀ for cardiomyopathy. Patients were selected on the basis of clinical criteria,X-rays, electrocardiograms, echocardiography, and coronary angiography. Responses were monitored by ejection fractions, cardiac output, and improvements in functional classifications (NYHA). Of the 88 patients 75%–85% showed statistically significant increases in two monitored cardiac parameters. Patients with the lowest ejection fractions (approx. 10%–30%) showed the highest increases (115%–210%) and those with higher ejection fractions (50%–80%) showed increases of approx. 10%–25% on therapy. By functional classification, 17/21 in class IV, 52/62 in class III, and 4/5 in class II improved to lower classes. Clinical responses appeared over variable times, and are presumably based on mechanisms of DNA-RNA-protein synthesis of apoenzymes which restore levels of CoQ₁₀ enzymes in a deficiency state. 10/21 (48%) of patients in class IV, 26/62 (42%) in class III, and 2/5 (40%) in class II had exceptionally low control blood levels of CoQ₁₀. Clinical responses on therapy with CoQ₁₀ appear maximal with blood levels of approx. 2.5 µg CoQ₁₀/ml and higher during therapy.Abbreviations CHF Congestive heart failure - CO Cardiac output - CoQ₁₀ Coenzyme Q₁₀ - EF Ejection fraction - IC Impedance cardiography - NYHA New York Heart Association - STI Systolic time interval
