Bacteria that move into the cardiovascular system increase the risk of heart attack. In trying to fight the bacteria, the body?s immune system causes the arterial walls to become inflamed, by sending greater blood flow to enlarge tissues and trap the germs. The increased blood flow and inflammation causes the acid plaque to break off more easily, and also increases blood pressure. Unless the acid accumulation in the body is reduced, your risk of heart attack and cardiovascular disease will continue to increase.
