Gender Differences in Presentation, Treatment, and In-Hospital Outcome of Patients Admitted With Heart Failure Complicated by Atrial Fibrillation (from the Get With the Guidelines-Heart Failure [GWTG-HF] Registry)

摘要

Almost 25% of patients with heart failure (HF) have coexisting atrial fibrillation (AF),, the latter of which may increase morbidity and mortality. Despite the high prevalence of HF with concomitant AF, this subgroup of patients remains understudied. This study examines gender differences in presentation, treatment and in-hospital outcome of patients with HE and AF. The Get With the Guidelines-Heart Failure (GWTG-HF) database enrolled 6,496 patients with HF who presented to Cooper University. Hospital from 2005 to 2012. Twenty-four percent (1,561 patients) had concomitant AF. Pearson chi-square tests and the Student T-tests were used to compare patient characteristics by gender. Multivariate logistic regression was used to predict in-hospital mortality. Six hundred sixty-nine (42.8%) patients with HF and AF were women. Women were older (p 0.001), had a higher ejection fraction (p 0.001), had systolic hypertension (p 0.001), and were more likely to have health insurance (p 0.001). Despite a higher CHADS2 score in women (p = 0.007), there was no gender difference in percent of anticoagulation medications prescribed before admission. Women were less likely to present with dizziness, lightheadedness, or syncope, and were more likely to be compliant with medications and diet recommendations before admission. Despite differences in presentation, co-morbidities, and therapy, in-hospital mortality was similar between men and women. Decreased appetite or early satiety predicted in-hospital mortality in women, whereas age, chest pain on admission, and decreased appetite or early satiety predicted in-hospital mortality in men. In conclusion, women presenting with HF complicated by AF clinically differ from men, but despite these differences, both groups shared similar symptom presentation and in-hospital mortality rates.
