IntroductionThe incidence of heart failure (HF), particularly in women, is increasing rapidly. While earlier reports indicated that HF mortality was higher in men compared to women, recent studies have suggested higher HF mortality in women. The cause of this changing pattern is not well described. The purpose of this study was to explore different clinical factors and management patterns that could contribute to this.MethodsWe conducted a retrospective chart review study of all the patients admitted to a tertiary academic hospital (Royal University Hospital, University of Saskatchewan, Canada) with a diagnosis of HF in 2015, with follow up analysis up to February 20, 2018.ResultsIn total, 379 patients were admitted with HF, of which 166 (43.8%) were women. Overall, the most important predictors of mortality on multivariate analysis include admission to non-cardiology services (NCS, p < 0.0001), age on admission (p<0.001), readmission (p=0.001), and haemoglobin on admission (P=0.004). Review of baseline characteristics showed that women with HF were older (p<0.001), and more likely to have HFpEF (26.3% vs. 46.4%, p<0.001) than men. However, women were less likely to have comorbidities including COPD, CKD, PVD, HTN, diabetes and dyslipidemia (p<0.001). In spite of this, there was a trend towards higher mortality among women over the follow up period (57.8% vs. 47.9%, p=0.055). Women were significantly less likely to be admitted to cardiology (62% vs. 71.4%, p=0.0084), and less likely to have follow up scheduled on discharge with either an internist or cardiologist (70.4% vs. 53.6%, p<0.001). Similar gender discrepancy in admission to cardiology was also observed among the subgroup of patients with HFrEF.ConclusionsIn our study, women admitted with heart failure had worse overall prognosis than men, in spite of less associated comorbidities. Admission to cardiology service was the most significant positive prognostic factor overall. However, surprisingly, women were significantly less likely to be admitted to cardiology, possibly contributing to their observed poor outcome. Further studies to elucidate factors underlying this observed difference in admission pattern may help improve the management of women with HF.
