What Is Congestive Diastolic Heart Failure

Heart is composed of 4 vessels, the upper vessels are called the atria and lower vessels are referred as ventricles. It is again sub-classified into right atria, left atria, right ventricles and left ventricles. The right atria and the right ventricle of the heart receive the impure blood from the body and pumps into the lungs. The left atria and left ventricle receives the blood from the lungs and pump it to the arteries of the heart to feed the purified blood to the rest of the organs of the body. Left ventricles are stronger than right ventricles as the former supplies blood to the whole body. When any of these functions of atria or ventricle are not executed well, it leads towards a heart failure. Congestive heart failure can be classified into two type’s namely systolic congestive heart failure and diastolic congestive heart failure or diastolic heart failure.

Systolic Vs Diastolic Heart Failure

The heart functionality is classified into two parts namely systole and diastole. Systole refers to the cardiac function where the heart tends to contract itself for supplying or ejecting the blood out of the heart to arteries and other part of bodies. This automated contraction of heart becomes relaxed and normal when the ventricles complete sending the blood out. After this phase, the heart receives the blood, i.e., refilled with blood for next set of cardiac cycle and this process of relaxation or transformation from contracted heart to relaxed heart is called diastole. Any kind of failure in this system is known as diastolic heart failure.

Systolic Congestive Heart Failure

Systolic heart failure is very different from the diastolic heart failure. Systolic heart failure refers to the condition of weakened heart or reduced functionality of pumping the blood. It means that the left ventricles are unable to contract it to supply the blood to the arteries. It is measured by a clinical or medical measurement called as EF – Ejection Fraction. EF refers to the computation and ascertainment of the quantity of blood flown out of the left ventricle of the heart divided by the total quantity of the blood remained in the left ventricle. A standard EF rate should be more than 50%, which means the left ventricle should release more than 50% of the blood stored. Eventually, systolic heart failure refers to the decreased amount of blood flow less than the minimum percentage of 50%. In simple terms, if the left ventricle fails to supply more than 50% of blood, it is called as systolic congestive heart failure, whereas the diastolic heart failure is associated with the expansion and relaxation of the heart.

Diastolic Congestive Heart Failure

Diastolic heart failure is quite opposed to the systolic heart failure, yet the condition is associated with the systolic process of cardiac cycle. Diastolic heart failure occurs when the heart fails to relax or expand itself to the normal size after supplying the blood by contracting itself. Sometimes, the left ventricles remain stiff after flowing out the blood and fail to diastole fully, which result with failure of receiving the full blood supply to the heart. This condition is called as abnormal ventricle filling, subsequently referred as diastolic dysfunction. The subsequent congestion of the left ventricles is called as diastolic heart failure.
