Contracts harder: The cardiac output is the stroke volume times the heart rate. So the heart has to contract harder and/or faster. Typically, in severe anemia, an echocardiogram would show the heart contractng harder than normal.

Oxygen: The delivery of oxygen to the body is the product of cardiac output and the amount of oxygen per unit of blood. If the amount of oxygen per unit of blood falls, the body reacts by increasing cardiac output so that the amount of oxygen delivered to the body is maintained.

Blood volume: Plasma volume is expanded in patients with chronic anemia to compensate for the reduce red cells thus cardiac output is increase even if the heart rate is unchanged.
