Abstract
Background: Previous studies suggest improved survival rates for women with heart failure. We report our experience with the New Zealand Heart Failure Registry (NZHFR). Methods: NZHFR is a national, prospective, observational web-based registry. We compared the short-term outcomes of hospitalised heart failure patients according to gender. Results: A total of 1609 patients were enrolled between July 2006 and Feb 2012 with 90-day follow up data available in 92% (1478/1609), 597 (37%) females and 1012 (63%) males. Women were older (mean age 74.3 ± 14.5 vs 67.4 ± 15.1, P < 0.0001) and had a higher incidence of hypertension (51% vs 49%, P < 0.0001) and severe valve disease (24% vs 20%, P = 0.04) and lower incidence of ischaemic heart disease (30% vs 36%, P = 0.006) and LV systolic dysfunction (LVEF < 50%, 57% vs 81%, P < 0.0001). There was no difference in BNP values (945 ± 1001 vs 862 ± 975, P = 0.10).

Shorter hospitalisation occurs in females with similar short term mortality and readmission rates to males.
