Title : Is there any association between etiologies and factors of acute decompensated Heart Failure ?
Introduction : Acute decompensated heart failure is a sudden or gradual worsening of the symptoms of heart failure in a background of chronic heart failure, early identification of the factor of ADHF is important for a better care, but an association between the factor and etiology of ADHF has not been established.
Objective: The purpose of this study is to determine whether the factor of acute decompensation is associated with the etiology of heart failure.
Methods: This was a retrospective observational study conducted over 2 years. Patients with ADHF secondary to common etiologies such Ischemic cardiomyopathy, dilated cardiomyopathy and valvular diseases were enrolled in the study. The frequencies of the etiology and factor of heart failure were derived. The Chi-square test was used to determine an association between categorical variables.
Results: There were a total of 138 participants. 60,9% Men ; 39,1% women. About etiologies : 39,9% Ischemic cardiomyopathy (ICM), 31,2% dilated cardiomyopathy (DCM) and valvular diseases in 21,7%. The factors were Infections 21.7%, ischemic attack 19,6%, anemia 13% %, non-adherance with salt/fluid intake 17,4 % non-adherence to treatment 10,9%, and arrhythmias 5,1%, There were a significant association between ICM and ischemick attack (p<0,001), non-adherance with salt/fluid intake (p=0,028) and arrhytmias (p=0,026). And between DCM and ischemick attack (p<0,001), and arrythmias (p=0,03), but no associations between valvular desease and the different factors.
Conclusion: ADHF comprises the etiology of heart failure and the factor triggering acute decompensation, the association between the etiology and the factor is variable. The factor of ADHF should be sought for every case for optimal management and better cares.
