Gender Differences in Utilization of Specialized Heart Failure Clinics

Although heart failure (HF) prevalence is equally high among men and women, observed differences in the provision of care are still not fully understood. We sought to evaluate gender differences in patient profiles, diagnostic testing, medication prescription, and referrals in specialized multidisciplinary ambulatory HF clinics in Ontario. Medical chart abstraction was conducted first by randomly selecting 9 (out of 34) HF clinics in Ontario, and then by randomly selecting 100 patient records in each clinic. Data on patient demographics, comorbidities, diagnostic tests, medication use, and referrals were abstracted, covering a period from the first clinic visit up to 1 year. Descriptive statistics and regression analysis were used to assess gender differences. Of the 884 patients, only 314 were women (35.5%). At the first clinic visit, women were older, had better systolic function but worse functional status, and had a lower prevalence of hyperlipidemia, diabetes, and smoking than men. There were more women with non-ischemic HF etiology than men (63.9% vs. 43.3%, p
