                    • Positive feedback loop
                      • Plaque narrows artery
                        • Heart finds it more difficult to pump blood around body
                          • Rise in blood pressure
                    • Ca+2 salts and fibrous tissue build up
                      • Hard swelling = plaque
                        • Artery loses elasticity
                  • White blood cells move into artery wall
                    • Bring other substances like cholesterol
                      • Atheroma forms
                • Caused by:
                  • High blood pressure
                  • Toxins in cigarette smoke
                  • High blood cholesterol
                  • High blood sugar
