Genetic and Electronic Medical Records to Predict Outcomes in Heart Failure Patients

Patients between 18 and 80 years old with heart failure diagnosis of different etiologies and left ventricular ejection fraction < 50% in the past 2 years will be eligible for enrollment on the cohort. After consent, patients will be submitted to clinical baseline, echocardiographic, cardiography impedance and biochemical evaluation. Study data will be collected and managed using Research Electronic Data Capture (REDCap) tools. The follow up will take place every 6 months to assess cardiovascular outcomes (all-cause mortality, cardiovascular mortality, hospitalization for worsening heart failure and current medication use). Initial analytical strategy will focus on the establishment of the accuracy of electronic medical records extraction protocols for main predictor factors of morbidity and mortality in heart failure.
