Heart dilation. Severe anemia decreases the oxygen carrying capacity of the blood, so the heart responds by increasing cardiac output. If the anemia is severe, one of the adaptations may be heart enlargement. Wall stress is higher in dilated ventricles, potentially, and this can lead to myocardial remodeling (scar).
