Final answer:
Congestive heart failure is a complex clinical syndrome that results from a cardiac disorder impairing the ventricle's ability to fill with or eject blood, causing inadequate oxygen supply to vital organs. Left untreated, it can lead to organ failure.
Step-by-step explanation:
Congestive heart failure is a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood. It means that the heart can't pump with sufficient force to transport oxygenated blood to all the vital organs. Left untreated, heart failure can lead to kidney failure and failure of other organs.
