The ability to develop collateral circulation is important in a person prone to heart disease because it provides an alternate route for blood to flow away from the heart to other areas of the body. This is beneficial for people who are prone to heart disease because the circulation of blood to and from the heart can be disrupted due to the narrowing of arteries. When this occurs, collateral circulation helps to ensure that the body receives an adequate supply of oxygen-rich blood to support healthy functioning. Additionally, the collateral circulation provides an alternate route for blood to be returned to the heart to help keep it in a healthy state.
