Mayo Clinic Heart Health: ‘What Is Hypertrophic Cardiomyopathy? ‘ (Video)

Hypertrophic cardiomyopathy is a thickening of the heart muscle, making it more difficult to pump blood. Dr. Steve Ommen is a Mayo Clinic cardiologist who specializes in the disease. He says shortness of breath or chest pain, especially during exercise, are common symptoms. Many people with the disease won’t have any significant health problems. But there are cases that require treatment. If a patient has symptoms that affect quality of life, the disease is treated with medications. Surgery or other procedures also may be necessary in some cases.

Heart Failure: ‘What Is It & How To Treat It’ (Video)

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.

Yale Medicine: ‘What Causes Heart Failure?’

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.
