E.1.1 | Medical condition(s) being investigated |
Heart failure is a condition that occurs when the heart loses its normal ability to pump blood to maintain vital body functions and, therefore, works with lower efficiency. Several studies have shown that deficiency of vitamin D would delete the renin gene, regulate the myocytes growth and facilitate ventricular hypertrophy, favoring cardiovascular damage and the incidence of heart failure. |
Lo scompenso cardiaco è una condizione che si ha quando il cuore perde la sua normale capacità di pompare sangue per mantenere le funzioni vitali dell'organismo e, quindi, lavora con sempre minore efficienza. Vari studi hanno dimostrato che la carenza di vit D sopprimerebbe il gene della renina, regolerebbe la crescita dei miocardiociti e favorirebbe l’ipertrofia ventricolare, favorendo danno cardiovascolare e l’incidenza di scompenso cardiaco. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To confirm the relationship between low serum levels of vitamin D and increased incidence of heart failure argued by the literature. |
Confermare i dati in letteratura circa la relazione fra livelli sierici bassi di vitamina D e aumentata incidenza di scompenso cardiaco. |
|
E.2.2 | Secondary objectives of the trial |
To verify the effectiveness of the additional therapy with vitamin D, proofing an improvement of cardiac contractility indices by an echocardiographic study and a reduction of cardiac fibrosis. |
Verificare l’efficacia della terapia supplementativa con Vitamina D, dimostrando un miglioramento degli indici di contrattilità cardiaca tramite studio ecocardiografico e un’eventuale riduzione della fibrosi cardiaca. |
