With increasing life expectancy, monitoring of chronic heart failure patients is more heterogeneous, because of the etiologies of the CHF, the severity of symptoms, and comorbidities. Many prognostic factors are described to help clinicians better determine the medium- and long-term prognosis. The aim of our study is to determine the main factors related to mortality and hospitalization for heart failure in the first year in a population followed in chronic heart failure.

It is a case-control study conducted between January 2014 and July 201, having compiled 237 patients (GT) followed in chronic heart failure with systolic dysfunction in the unit of treatment of heart failure. Among these patients, the death rate is 11.4% and hospitalization for heart failure is 52.1%, making a total event during the first year of 63.3% (GC). The average age is 63.3 years and 72.9 years respectively in the GT and GC. The two groups did not differ as to gender, cardiovasclar risk factors, except for diabetes, which is more present in the GC (p=0.04). Clinically, a NYHA class III or IV is found in 12% and 45.8% respectively in the GT and GC (p<0.05). The ischemic etiology is predominant in the GC. In the electrocardioram, atrial fibrillation was found in 5.34% and 44.1% respectively in the GT and GC (p<0.05). The median of the LVEF was 41% and 31.3% respectively in the GT and GC (p<0.05). Biologically, anemia is found in 5% and 10.3% respectively in the GT and GC (p<0.05). Creatinine clearance less than 60ml / min is observed in 17.5% and 37.6% respectively in the GT and GC (p<0.05).

In our population, the mortality rate and rehospitalization are high. This risk is particularly increased in older patients with more comorbidities, which have an arrhythmia, and having a more impaired LVEF.
