Background:

Sacubitril/valsartan, has been found to be more beneficial than enalapril for reducing the incidences of sudden cardiac death, death from worsening heart failure (HF), and hospitalization. However, there is no prospective echocardiographic data describing the effects of sacubitril/valsartan on the heart functions and left ventricular (LV) reverse remodeling. Therefore, the aim of our study was to evaluate the effects of sacubitril/valsartan on the LV functions using two dimensional (2D), three dimensional (3D) echocardiography and the 3D strain parameters.

Methods:

In 100 patients with HF with reduced ejection fraction (HRrEF) who have indications for the use of sacubitril/valsartan as recommended by recent guidelines were prospectively enrolled. The basal 2D and 3D echocardiographic parameters were compared to those obtained 3 months after starting the sacubitril/valsartan treatment.

Inclusion Criteria:

• Age is more than or equal 18 years old
• Able to provide written informed consent
• Indicated for the use of sacubitril/valsartan as recommended by the European Society of Cardiology (ESC) heart failure guidelines 2016
• Left ventricular ejection fraction of 40% or less

Exclusion Criteria:

• Cardiac resynchronization therapy (CRT) device implantation less than 3 months prior to the start of this study or CRT implantation intentions
• Atrial fibrillation
• Poor echocardiographic images
• Sacubitril/valsartan treatment intolerance during the follow-up period

One hundred patients with heart failure with reduced ejection fraction (HRrEF) who have indications for the use of sacubitril/valsartan as recommended by recent guidelines were prospectively enrolled.
