The heart is a hero. It works relentlessly to deliver oxygen and nutrients to the body. But just like all heroes, sometimes it gets tired, and can’t do its job as well. This is called heart failure – the inability of the heart to pump enough blood and oxygen to the lungs and rest of the body. In this video, Northwestern Medicine cardiologists Clyde W. Yancy, MD, MSc, and Jane E. Wilcox, MD, MSc explain what heart failure is and the integrated and collaborative approach used to diagnose, stage, and treat heart failure at Northwestern Medicine.
