Most heart murmurs are innocent, which means your heart is healthy, and you don’t need any treatment. But the exceptions are heart murmurs can be linked to a damaged or overworked heart valve. Some people are born with valve problems. Heart murmurs can also be caused from aging, or from other heart problems. Heart murmurs are abnormal sounds — such as whooshing or swishing — during your heartbeat cycle made by turbulent blood in or near your heart, usually caused by a heart valve not properly opening or closing. The valves close and open to let blood flow through the heart’s two upper chambers (the atria) and two lower chambers (the ventricles). These sounds can be heard with a stethoscope. The “murmur” is the sound of blood flowing. It may be passing through a heart valve that has problems, for instance. Or it may be that a condition is making your heart beat faster, forcing your heart to handle more blood quicker than normal. Heart murmurs are the result.
Heart murmurs can be present at birth (congenital), Some people are born with valve problems, or develop later in life. Heart murmurs may be linked to a damaged or overworked heart valve. Heart murmurs can also be caused from aging, or from other heart problems. A heart murmur isn’t a disease — but murmurs may indicate an underlying heart problem. Some heart murmurs may require follow-up tests to be sure the murmur isn’t caused by a serious underlying heart condition. Treatment, if needed, is directed at the cause of your heart murmurs.
