This is hereditary if there are heart problems in your family. My husband recently died on 5/26 an Autopsy showed that he had atherosclerosis.He smoked and rarely drank.but I found out that both of them make this progress rapidly. So it is good that you don't smoke. The doctor thought that my husband had acid reflux because of the chest pains that he was having. He was only 43.If you keep your bad cholestreol down and your stress level down. You will live a long life.
