Objective: Left ventricle systolic dysfunction is a serious cardiovascular condition that causes morbidity and mortality. Congestion is not a feature in every patient and the factors affecting congestion is not clearly defined. The aim of this study is to determine the factors causing congestion in elderly patients with left ventricle systolic dysfunction. Method: Total number of 101 patients admitted to Cardiology and Internal Medicine outpatient clinics with left ventricle systolic

... (ejection fraction < 40%) were enrolled in the study. Cardiovascular risk factors, chronic obstructive lung disease and other systemic diseases of the patients were evaluated. Congestion was determined and graded according to their clinic. Results: Mean age of the patients was 62,7±6,7 and 54 (54%) were male. Mean left ventricle ejection fraction was 31.1±5.8. Multivariate regression analysis revealed that chronic obstructive lung disease (t=4,528, p<0,001), left ventricle end diastolic diameter (t=3,149, p=0,002), and atrial fibrillation (t=2,137, p=0,035) were independent predictors of congestion. Conclusions: In elderly patients with left ventricle systolic dysfunction chronic obstructive lung disease, ventricle end diastolic diameter, and atrial fibrillation were found related to congestion. Evaluating and managing these factors in elderly patients with left ventricle systolic dysfunction might be important in preventing congestion.
