Abstract

Background: Heart failure (HF) is an increasingly prevalent condition with significant morbidity and mortality. Guideline-directed medical therapy (GDMT) reduces morbidity and mortality in heart failure with reduced ejection fraction, but continues to be under-prescribed. There is a paucity of data on the impact of patient gender on the quality of HF care, although it has previously been shown that women with other cardiovascular conditions, such as coronary artery disease, receive less intensive treatment. We sought to determine whether there is a difference in rates of prescription of GDMT for patients hospitalized with heart failure by gender with the hypothesis that rates of GDMT prescription in women would be lower than that in men.Methods: Over a six month study window, we identified 246 patients discharged from an urban academic medical center with a primary discharge diagnosis of systolic heart failure. Systematic chart review was performed to identify whether patients were discharged with the following medications: angiotensin converting enzyme inhibitor (ACE-I), angiotensin receptor blocker (ARB), beta blocker (BB), mineralocorticoid receptor antagonist (MRA), hydralazine and a nitrate, and neprilysin inhibitor/ARB. Statistical analysis was performed to evaluate for an association between rates of GDMT prescription and gender. Regression analysis was then performed to adjust for age, weight, serum potassium, and 1/(discharge creatinine).Results: At the time of discharge, there was no statistically significant difference in the rate of GDMT prescription for females compared to males in either the unadjusted or adjusted models. ACE-I or ARB prescription rates were 59% in females and 50% in males (p=0.11); BB prescription rates were 89% in females and 84% in males (p=0.27); MRA prescription rates were 43% in females and 52% in males (p=0.19). Prescription rates of combination therapy of ACE-I or ARB with BB and MRA were 30% in females and 31% in males (p=0.78). There was a significant difference in 30 day all-cause unadjusted readmission rates in females (22%) compared to males (37%) (p<0.05).Conclusions: In this sample of hospitalized heart failure patients, no difference was found in rates of GDMT prescription for women as compared to men. Readmission rates were significantly higher for men than women, consistent with national data. Further investigation will determine the extent to which equity in prescription rates translates into improved outcomes for women hospitalized with heart failure.
