Heart Failure Support Group
Heart failure is a condition that can result from any structural or functional cardiac disorder that impairs the ability of the heart to fill with or pump a sufficient amount of blood throughout the body. It is often undiagnosed due to a lack of a universally agreed definition and difficulties in diagnosis, particularly when the condition is considered "mild."

Fern ~ Actually a stress test and an echo (echocardiogram) are two different animals and check different aspects of the heart. No single heart test gives a complete picture of how the heart is performing. An Echo is primarily a plumbing check. A stress test is primarily electrical.
