Why Even Fit People Are At Risk of a Heart Attack - Damage Artery Linings caused plaque formation

Think heart attacks only happen to people who are unhealthy or don't exercise? Think again. In this video, Jonathan from the Institute of Human Anatomy, breaks down the incredible story of his athlete brother who suffered a heart attack during a half-marathon, and what the angiogram revealed about his heart. Diabetes, stress, high blood pressure, unhealthy food and smoking, can continue to cause inflammation in our artery endothelium linings . Chronic inflammation will cause damage or tear in these linings. When this happen, cholesterol & other fatty substances will be pushed out to the back of the lining and they get stuck. If this damage is not being repaired by our body's stem cell, then the buildup will continue until the whole artery is blocked and lead to heart attack.
