Cardiology A concept that refers to ↓ cardiac output due to ↓ renal blood flow, and altered glomerular filtration with retention of salt and water, causing a secondary ↑ in blood volume. Cf Backward failure.

The latter was probably facilitated by massive left-to-right shunt and associated severe forward failure. Shortly after the CT scan the patient had to be resuscitated again, but due to futility with subtotal body ischemia without any option for MCS or emergent surgery resuscitation was terminated.
Clinical signs seen in CHF are as a result of congestion and forward failure (Knight, 1994).
Therefore left ventricular diastolic dysfunction can thus cause symptoms of both backward failure (dyspnea) as well as forward failure (easy fatigability).
When the left ventricle weakens, forward pumping action into the aorta is weak, thus causing diminished cardiac output and decreased systemic arterial perfusion (often referred to as "left-sided forward failure").
