Professor Dan Atar is a cardiologist who has authored and contributed to several heart failure and atrial fibrillation guidelines. He discusses key clinical aspects of heart failure management based on the ESC guidelines. First, inpatient treatment focuses on recompensation of acute heart failure, which carries a high mortality risk. Ensuring an uptitration plan and follow-up appointment at discharge is important. In the outpatient setting, adherence to therapies needs to be secured given the risk with multiple daily dosing, and comorbidities and polypharmacy must be adequately addressed.
