A Multi-center, Prospective, Randomized, Double-blind Study to Assess the Impact of Sacubitril/Valsartan vs. Enalapril on Daily Physical Activity Using a Wrist Worn Actigraphy Device in Adult Chronic Heart Failure Patients

The purpose of this randomized, actively controlled, double-blind study with prospective data collection was to assess differences between sacubitril/valsartan versus enalapril in increasing exercise capacity and non-sedentary physical activity in HFrEF patients. Physical activity was assessed by the 6 minute walk test, and daily physical activity was continuously measured by means of a wrist-worn accelerometry device from 2 weeks before until 12 weeks after start of study therapy (sacubitril/valsartan or enalapril).
