I was diagnosed with a small heart mummur 11 years ago when I was pregnant with my son. Doctors told me it was small and it was nonthing to worry about. My mother and her side of her family have Congestive Heart Failure. I need to know, will I develope this problem when I get older. I will be 40 this year. I had a stress test, and the results were good. My heart is strong and in good condition. I am a very healthy woman occording to my doctor. I am just curious to know this. Some People can have a small problem with their heart, like a small heart mummur and later in life develope problems, because of family history. At this time, my doctor can barely hear my mummur. Should I worry?
