Prognostic relevance of metabolic approach in patients with heart failure.
Progressions in acute cardiac care have improved survival after acute myocardial infarction, but in contraposition with this, there has been an increase in mortality because of heart failure. For this reason congestive heart failure is an increasingly widespread, costly and deadly disease, frequently named as epidemic of the XXI century. Despite advancement in modern treatment, mortality rate in heart failure patients remains high. In these patients more importance was attributed in the management of the left ventricle dysfunction. In fact, the heart failure patients have still a poor prognosis due to the ineluctable progression of contractile dysfunction and ventricular remodeling. The classical management of left ventricle dysfunction includes the pharmacological treatment with beta-blockers, ACE-inhibitors and aldosterone antagonists, and various surgical or electrophysiological interventions. Emerging evidence suggests that myocardium dysfunction is also due to substrate metabolism alterations. In particular, there is evidence that, in the failing heart, shifting metabolism away from a preference for fatty acids towards more carbohydrate oxidation could recover contractile function. Trimetazidine has been shown to improve symptoms and ventricular function and to have a beneficial effect on the inflammatory profile and endothelial function in these patients. Recently, it has been suggested that trimetazidine could also reduce ventricular remodeling, slowing down the progression of pump failure, and improve prognosis. These results suggest that trimetazidine is a useful adjunct to our current armamentarium for the treatment of heart failure patients.[1]References
