When heart becomes stretched and weakened and not able to pump effectively, such condition is called dilated cardiomyopathy. If the right side of the heart is affected, heart failure happens when the heart is not able to pump strongly enough to meet the needs of the body. In such a case tissues in the body do not get enough oxygen. If the left side of the heart is affected, it is unable to pump enough blood to the rest of the body. In most cases, heart failure affects both left and right side, but it can occur on just one side. Heart failure in most of the cases becomes life-threatening and no more manageable through with medical therapies. This session discusses about heart failures and cardiomyopathy and finds out how to improvise the life-expectancy of people suffering from several types of heart diseases.
