There are important gender-related differences regarding the onset of heart failure (HF), the features of established chronic HF, and the clinical characteristics at admission for acute HF [1,2]. Compared with men, women have more often hypertension, atriumfibrilleren, preserved left ventricle ejection fraction (LVEF), a longer length of hospitalization, and receive less diuretic medication, whereas men are more likely to have a history of myocardial infarction, reduced LVEF, and specific medical and device treatment [3,4].
In this analysis of the RELAX-AHF study [5,6], the gender differences in early and persistent dyspnea relief were investigated. Moreover, patient features and HF characteristics in men and women hospitalized for acute HF were analyzed.
In the RELAX-AHF study, women had better early dyspnea relief and improvement in general wellbeing compared with men, even after adjustment for age and LVEF. In-hospital and post-discharge clinical outcomes were similar between men and women.
