Conditions: 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.

Primary Outcome Measures

Name	Time	Method
Main Objective: To confirm the relationship between low serum levels of vitamin D and increased incidence of heart failure argued by the literature.;Secondary Objective: 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.;Primary end point(s): EF (ejection fraction) % (B-mode measurement) measured by echocardiogram;Timepoint(s) of evaluation of this end point: nd

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): 1.wall thickness (IVS and PW) in mm (M-mode measurement) left ventricular mass index calculated by: 0.832* [(Dd+IVSd+PWd)3 – Dd3] + 0.6g (Dd is the left ventricular telediastolic diameter, IVS is the interventricular septum thickness, PWd is the diastolic posterior wall thickness) 2.Parameters of relaxation (E/A ratio) 3.DT in mm/sec 4.Serum carboxy-terminal propeptide of procollagen type I;Timepoint(s) of evaluation of this end point: nd
