Does heart failure therapy differ according to patient sex?
OBJECTIVE
To assess differences in clinical characteristics, treatment and outcome between men and women with heart failure (HF) treated at a multidisciplinary HF unit. All patients had their first unit visit between August 2001 and April 2004.


METHODS
We studied 350 patients, 256 men, with a mean age of 65 +/- 10.6 years. In order to assess the pharmacological intervention more homogeneously, the analysis was made at one year of follow-up.


RESULTS
Women were significantly older than men (69 +/- 8.8 years vs. 63.6 +/- 10.9 years, p < 0.001). Significant differences were found in the HF etiology and in co-morbidities. A higher proportion of men were treated with ACEI (83% vs. 68%, p < 0.001) while more women received ARB (18% vs. 8%, p = 0.006), resulting in a similar percentage of patients receiving either of these two drugs (men 91% vs. women 87%). No significant differences were observed in the percentage of patients receiving beta-blockers, loop diuretics, spironolactone, anticoagulants, amiodarone, nitrates or statins. More women received digoxin (39% vs. 22%, p = 0.001) and more men aspirin (41% vs. 31%, p = 0.004). Carvedilol doses were higher in men (29.4 +/- 18.6 vs. 23.8 +/- 16.4, p = 0.03), ACEI doses were similar between sexes, and furosemide doses were higher in women (66 mg +/- 26.2 vs. 56 mg +/- 26.2, p < 0.05). Mortality at 1 year after treatment analysis was similar between sexes (10.4% men vs. 10.5% women).


CONCLUSIONS
Despite significant differences in age, etiology and co-morbidities, differences in treatment between men and women treated at a multidisciplinary HF unit were small. Mortality at 1 year after treatment analysis was similar for both sexes.
