Objectives To explore the prevalence, distribution and prognosis of Atrial fibrillation on systolic dysfunction of congestive heart failure (CHF) in hospitalised patients.
Methods We reviewed the medical records of 462 unselected consecutive patients with heart failure who were admitted to our Hospital between 1, 2009 to 1, 2010, patients were categorised as having systolic dysfunction with LVEF < 50% based on the results of echocardiography. We compared the 1 years clinical outcomes (stroke, myocardial infarction, unstable angina and cardiovascular death).
Results AF was documented in 166 patients (36%), including 87 patients (19%) at baseline and 79 patients (17%) during subsequent follow-up with systolic dysfunction of CHF. The occurrence of AF in patients of heart failure with LVEF < 50% was associated with an increase numbers of hospitalisation and shorter time interval for readmission for CHF(P < 0.05).
Conclusions AF occurred in up to 1/3 patients with systolic dysfunction of CHF. The occurrence of AF did not affect the 1 year outcomes in these patients, but increased their numbers of hospitalisation for CHF. Therefore treatment and prevention of AF have important implication in the management of patients with systolic dysfunction of CHF.
