CCS/CHFS Heart Failure Guidelines Update: Defining a New Pharmacologic Standard of Care for Heart Failure With Reduced Ejection Fraction.

In this update of the Canadian Cardiovascular Society heart failure (HF) guidelines, we provide comprehensive recommendations and practical tips for the pharmacologic management of patients with HF with reduced ejection fraction (HFrEF). Since the 2017 comprehensive update of the Canadian Cardiovascular Society guidelines for the management of HF, substantial new evidence has emerged that has informed the care of these patients. In particular, we focus on the role of novel pharmacologic therapies for HFrEF including angiotensin receptor-neprilysin inhibitors, sinus node inhibitors, sodium glucose transport 2 inhibitors, and soluble guanylate cyclase stimulators in conjunction with other long established HFrEF therapies.
