Global cardiology organizations, including the American Heart Association and the European Society of Cardiology, have proposed a revised consensus for defining heart failure. This new framework, published in the journal ‘Circulation’, suggests that a ‘normal’ pumping capacity does not necessarily rule out the condition. The goal is to provide a more consistent clinical framework to improve prevention and treatment.

Following this consensus, new European guidelines have introduced a four-stage classification system designed to facilitate earlier detection. The stages range from Stage A, involving a healthy heart with risk factors like hypertension or obesity, to Stage D, representing advanced heart failure. Medical experts note that identifying the condition in the earlier, often asymptomatic stages offers the greatest opportunity for impactful intervention.
