Systolic and diastolic heart failure

Systolic and diastolic heart failure

Systolic and diastolic heart failure are overlapping phenotypes in the heart failure spectrum, which require different medications and treatments. Heart failure with preserved EF is also called diastolic failure (or diastolic dysfunction). The left ventricle loses its ability to relax naturally (because the muscle has become stiff). The heart can’t correctly fill with blood during the resting period between each beat. Systolic heart failure happens when the left ventricle of your heart cannot contract completely. That means the heart cannot pump forcefully enough to move your blood throughout your body in an efficient way. It’s also called heart failure with reduced ejection fraction (HFrEF).

The patient is suffering from systolic failure.

Dyspnea on exertion occurs due to the failure of the left ventricular output incase of aggressive activity. This works to increased pulmonary venous pressure. Pitting edema is the swelling of limbs due to the accumulation of fluids in the lower parts of the body. It is caused by heart valve problems & Vasan, R. 2007). a congestive cardiac failure causes jugular vein distention. Pressure in the vena cava doubles and makes the jugular vein bulge and observable on the neck’s right side. Orthopnea is the difficultly experienced in the breathing process as a result of left ventricular heart failure.

The relationship between heart failure and ejection fraction can be complicated.

As you would expect, if EF is low, a patient can develop heart failure – that cutoff value is usually taken to be 35–40%. Normal is considered to be 55–75%. However, a patient can have low EF yet not develop heart failure (at least not immediately). There are patients with an EF towards the lower end of normal who develop heart failure anyway. It is not always so simple as short EF = heart failure.
