Goreisan as a successful adjuvant therapy of heart failure with preserved ejection fraction and advanced chronic kidney disease: a case report

Abstract

Atrial functional mitral and tricuspid regurgitation due to atrial fibrillation (AF) are common causes of heart failure with preserved ejection fraction, but standard treatment with conventional diuretics can often lead to renal dysfunction. Kampo Goreisan, a traditional Eastern-Asian herbal medicine that regulates body water balance via the aquaporin-incorporated water reabsorption system can be used as an alternative therapy without causing renal burden. In this report, we describe a case of successful treatment with Goreisan of heart failure with preserved ejection fraction (HFpEF) due to atrial functional mitral and tricuspid regurgitation (AFMR/TR) receiving guideline-directed medical-therapy. Goreisan could afford amelioration of regurgitation and improvement bilateral systolic ventricular function without renal dysfunction. Thus, Goreisan may be a promising therapeutic option for patients refractory to conventional diuretics.
