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 for 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.

The heart is a muscle and it’s main job is to pump blood but certain things can cause that muscle to fail. There are genetic reasons, there are reasons related to valve disease, and there’s a viral infection that affects the heart called myocarditis.
The most common cause of heart failure is a heart attack. Fatty plaque builds up in the blood vessel that supplies the heart itself and unless that blood vessel is opened up immediately that muscle will die. The rest of the muscle that’s not dead anymore has to do extra to keep on pumping the blood and overtime it cannot keep and that’s when heart failure develops.
Mayo Clinic Division of Preventive Cardiology will be preparing a series of recordings focusing on Cardiovascular Disease states. This is the Exercise Series and this particular one focuses on exercise and the heart.
First up, host Meagan Cantwell speaks with Abigail Echo-Hawk, director of the Urban Indian Health Institute and chief research officer for the Seattle Indian Health Board. Echo-Hawk shares what inspired her journey in public health and explains the repercussions of excluding native people from health data.
This story was originally reported by Lizzie Wade, who profiled Echo-Hawk as part of Science’s “voices of the pandemic” series. Next, host Sarah Crespi interviews Danielle Murashige, a Ph.D. student at the University of Pennsylvania, about her Science paper that attempts to quantify how much fuel a healthy heart needs.
The US Surgeon General’s office has released a report emphasizing the importance of making hypertension control a national public health priority. Vice Admiral Jerome Adams, MD, MPH, the 20th US Surgeon General, discusses the report’s background and recommendations.

CENTERS FOR DISEASE CONTROL & PREVENTION (August 25, 2020) – A CDC study published today that looked at more than 80,000 U.S. adults hospitalized with flu over eight flu seasons (2010-11 through 2017-18) found that sudden, serious heart complications were common and occurred in one out of every eight patients (~12% of patients).
The study looked at a range of sudden heart complications called “acute cardiac events” that resulted in the following:
- damage to the heart muscle,
- inflammation of the heart muscle,
- fluid or inflammation of the sac surrounding the heart, or
- weakening of the pumping function of the heart.
The most common acute cardiac events reported in the study were acute heart failure and acute ischemic heart disease. Acute heart failure is the sudden inability of the heart to pump enough blood to meet the body’s demands, while acute ischemic heart disease is a term that describes heart problems caused by narrowed or blocked heart arteries.
Hospitals across the U.S. are experiencing an influx of COVID-19 patients, but clinicians are reportedly seeing fewer patients going to the emergency room for heart attack or stroke.
Experts worry that patients who need critical care are delaying their treatment over COVID-19 concerns.
To encourage patients to pay close attention to their symptoms and call 9-1-1 immediately if they believe they are having a heart attack or stroke, ACC’s CardioSmart team developed the Coronavirus and Your Heart Infographic.
The infographic urges patients not to ignore symptoms, especially if they have a heart condition, and reassures them that hospitals have safety measures to protect patients from infection with the novel coronavirus.
On the Mayo Clinic Radio program, Dr. Todd Miller, a Mayo Clinic cardiologist, explains how exercise affects the heart. This interview originally aired Feb. 22, 2020. Learn more about exercise and the heart: https://www.mayoclinic.org/healthy-li…
