Heart murmurs that are innocent usually go away around what ages?

Depends. Innocent heart murmurs are normal sounds that the heart makes. The are most often heard during young childhood, but can be heard throughout life. It doesn't matter if they go away or not, as it is not a heart condition or problem, but a normal sound. All of our hearts make normal sounds, it is just that those with innocent heart murmurs have some sounds easily heard with a stethoscope.
Highly variable. An innocent heart murmur is due to turbulent blood flow as opposed to a structural abnormality such as a malfunctioning valve or an abnormal conduit. Fever, pregnancy, anemia and thyroid excess are examples of states associated with innocent murmurs at any age. Many children have innocent murmurs and they may come and go. Age isn't the only factor.

Likely Normal. I'd recommend that your son see a pediatric cardiologist if the pcp feels the murmur is unusual or if it has changed. However, those vital signs are pretty normal given his age. A murmur is just an extra sound, it may or not mean there is a problem. A pediatric cardiologist will be able to assess the location, quality, and timing of the murmur to determine if any additional tests need to be done. Read more...
It's something else. Most heart murmurs that have never required intervention by age 14 are simple flow murmurs of little significance. The other numbers you provide are well within the normal range.
