Barb, you and your husband are in my prayers. And congratulations of the quitting smoking. Keep it up and you will be rewarded in many ways.
My husband went to his doctor when he first experienced chest pains. They caught it in time to prevent a heart attack. The left anterior descending was 100% blocked. He had to have bypass surgery at age 47. He didn't smoke, cholestrol was great, skinny as a rail, and ate a fairly healthy diet. Through cardiac rehab he learned even healthier eating. Doctors are amazed with his good health at age 62.
