Heart murmurs in adults are just like those found in children in that they are actually a symptom of a large number of possible heart conditions. The murmur itself is a sound that is produced due to “turbulent bloodflow”. Heart murmurs can typically only be heard with a stethescope. Once a murmur is detected it is typically either classed as a systolic or diastolic murmur, although one can also have a continuous murmur, which fall into both categories.
Heart murmurs in adults tend result either from heart valve defects, injury caused to the heart or from relatively harmless external factors. Often you won’t even notice heart murmurs and we can all have them from time to time, although it is less common in adults that it is in children. Children have heart murmurs as a matter of course whilst growing up, especially considering how the heart and circulatory system changes drastically shortly after birth. Children are routinely screened so most congenital heart defects show up at this stage. That is perhaps the main difference between heart murmurs in adults and those in children. That is not to say that congenital defects cannot become symptomatic later in life to cause murmurs.
Heart murmurs are generally treated only if the underlying condition causing the murmur is of concern. The mere fact that you have a heart murmur does not mean that you need medical intervention. Remember, the heart murmur is not the cause, it’s the symptom that can accompany other symptoms. Don’t stress out if your doctor tells you that you have a heart murmur, if you’ve made it that far, you’re likely in good hands.
