[Possibilites for the prevention of heart failure - an internist’s take]

KIS János Tibor

[Because of the high prevalence of heart failure in the general population, its prevention and treatment should be part of every clinicians’ knowledge base. The author summarizes lifestyle and dietary advices, as well as general medication considerations that might have a preventive effect on the development or progression of heart failure. ]

[EXPERIENCE WITH COENZYME Q10 IN HEART FAILURE]

KOHUT László

[INTRODUCTION - The protein complex coenzyme Q10 (CoQ10) has a role in ATP production as a mitochondrial electron transport molecule, and it also has a strong antioxidant effect. Several studies have proved the correlation between the decrease in CoQ10 level and the severity of heart failure. Heart failure is a multifactorial syndrome, the development of which is greatly influenced by an abnormal energy metabolism. CASE REPORT - The 61-year-old woman developed heart failure after a myocardial infarction. She complained of fatigue, dyspnoea and reduced physical endurance even with optimal treatment. When her therapy was completed by CoQ10, her endurance and life quality significantly improved and her symptoms ameliorated. CONCLUSIONS - Medical treatment of chronic heart failure is an evidence-based, complex therapy. Despite the complex management, morbidity and mortality of this condition remain high. A number of studies have shown that CoQ10 substitution can improve the clinical and haemodynamical parameters of patients with heart failure. On the basis of these results, the use of CoQ10 as an adjuvant therapy to complex treatment has an increasing role.]

[STATIN DRUGS DECREASE THE PLASMA COENZYM Q10 (UBIQUINONE) LEVEL IN ORGANISM]

RÁKÓCZI Károly, PÁRDUTZ Árpád, VÉCSEI László

[In this paper the authors review the relationship and the possible interaction between the HMG-CoA reductase inhibitors (statins) and the CoQ10 (ubiquinone) based on the current literature. The statins are widely used in the clinical practice. Inhibiting the synthesis of mevalonic acid they decrease the plasma cholesterol level. Since mevalonic acid is also required for ubiquinone synthesis statins could influence ubiquinone metabolism. Many studies confirmed the relationship between statin therapy and lower plasma ubiquinone level. Much less data are available about the tissue concentration changes of ubiquinone during statin therapy. The authors try to summarise the consequences of the interaction between statin therapy and ubiquinone metabolism.]
