Do you smoke? (not necessarily a question for the original poster) Smoking causes mush more heart damage than lung. If you smoke quit, now. My father smoked and died at 52. My uncle smoked and died at 52. You can tell all the stories you want about uncle Ed who smoked two packs a day and lived to 100 but there are many more like my father and uncle. Maybe if my father did not smoke he would have lived long enough to bounce his first grandchild on his knee.
My sister in law smoked heavily from her teens til just a couple of years ago in her late 50s when she was diagnosed with COPD. A couple of months ago she fell and hit her knee on a small rock, shattering her leg bones below the knee. Three surgeries and over 75 stitches later she may have problems for the rest of her life. She almost lost a foot over the damage.
There days later I had major surgery on my leg to repair damage from 40 years ago. She is still in a wheelchair and walker and I am walking without crutches. The doctor said that smoking does more damage to your bones than just about anything else.
If you smoke, stop. I stopped smoking when my now 41 year old son was 1, for him. I recently had some tests which included some tests on the heart and there is no problem there at all. I turn 67 in March. I am over weight but am working on that now.
