Per Yale Medicine, congestive heart failure refers to the heart’s inability to meet the body’s need for blood.
As the heart weakens, blood begins to back up and force liquid through the capillary walls, which results in a buildup of fluid in the appendages and organs.
According to the Centers for Disease Control and Prevention, cardiomyopathy refers to a collection of diverse heart conditions which cause the muscle to thicken, stiffen, thin out or fill with bodily substances.
Cardiomyopathy can be acquired or developed.
