What is phasic heart failure?

Discovery Health answered:Blood has oxygen and nutrients and the heart's job is to provide these to the whole body. Congestive Heart Failure (CHF) is when the heart cannot perform this function adequately. It occurs when cardiac output - another way of describing the blood flow from the heart - decreases. CHF can be a fluid back-up behind the failing ventricle, or a combination of fluid back up and decreased cardiac output.
The heart can fail in either the contraction (systole) or rest (diastole) phase of the cardiac cycle. This is called phasic heart failure.
In Systolic heart failure, the heart has difficulty contracting and can't pump out enough blood. Symptoms are weakness, fatigue and decreased ability to exercise.
In Diastolic heart failure, the heart can't fill properly during diastole, the rest phase, which is usually due to increased filling pressure. Symptoms are systemic or pulmonary edema or both.

Amanda Trujillo of Honor Society of Nursing (STTI) answered:From a healthcare consumer's view, phasic heart failure is a way of saying what part of the heart's contraction and blood filling cycle is the cause of the heart failure. For instance, there is a phase where the heart receives blood from the lungs and it is "pushed down" into the left ventricle and the ventricle expands/stretches to receive that blood. That is one phase and it’s called the "Diastolic phase."
The second phase is the part where the left ventricle shunts the blood through the valve that leads to the aorta and the rest of the body (organs). This second phase is called the "Systolic phase." A problem in the heart that can occur during systolic heart failure is the inability of the ventricle to receive all the blood from the lungs because of the heart muscle's inability to stretch enough (muscle stiffness). When this happens, the left ventricle is left with a small amount of blood that eventually will not be enough to send out to the rest of the body.
In Systolic Heart Failure (the shunting phase of blood out to the rest of the body) the problem can occur for two reasons: either there is a narrowing of the valve the left ventricle has to force the blood through, or the left ventricle has become so enlarged and "floppy" it no longer has the appropriate "force" to empty all the blood from its chamber.
If you hear the terms "phasic heart failure" Just remember it means the filling stage (diastolic) and the emptying stage (systolic). Doctors are talking about "why and where" the heart failure is happening when they use these terms.
