Role of metabolic therapy in cardiovascular disease

The pathophysiological basis for the use of metabolic therapy in the treatment of heart failure is analyzed. Bioenergetical processes related to ATP bioavailability play a central role in regulating myocardial contractility at rest and on effort. Furthermore, a significant correlation has been demonstrated in diseased heart between ATP content, revealed at endomyocardial biopsy, and systolic and diastolic left ventricular indexes evaluated with invasive and noninvasive methods. Several international investigations demonstrate the beneficial effects of ubiquinone (coenzyme Q10) in the treatment of heart failure. Here the results of a study are reported that was conducted on patients with heart failure treated with ubiquinone. After 7 months of oral drug administration (100 mg/day), a significant improvement was observed in echocardiographic indexes of systolic function, cardiothoracic ratio, and clinical signs and symptoms of congestive heart failure. In conclusion, the introduction of metabolic drugs, such as ubiquinone, in the treatment of heart failure opens new horizons in the therapeutic approach to an ailment that entails substantial human and social costs.
