MOLECULAR PATHWAYS OF CARDIC REMODELLATION IN PATIENTS WITH ACUTE AND CHRONIC LEFT VENTRICULAR DISFUNCTION

Chronic heart failure represents an extremely complex clinical syndrome, defined as the inability of the heart muscle to generate a volume adequate to the metabolic needs of peripheral tissues, or to do so only in the face of high filling pressures intracavity. Heart failure is one of the leading causes of mortality and morbidity in Western countries.Despite advances in the therapeutic field, the prognosis of patients with heart failure of ischemic and non-ischaemic aetiology still remains unfavorable, with a mortality rate of 50% 5 years after the first hospitalization.Therefore, a deeper understanding of the pathophysiological mechanisms involved in heart failure and adverse ventricular remodeling is essential.
