Do I need to be worried about an incidental heart murmur?

I understand your concern about knowing that you have a heart murmur. It is great that you have undergone further testing such as TTE and ECG and both are normal. It is not unusual that incidental heart murmurs are picked up during health screening or routine doctor's visits.

Generally, if you have been able to exercise with no significant shortness of breath, fainting during exercise or family history of sudden deaths, they are usually not of concern. However, you may want to discuss with a cardiologist if there is a need to do further testing such as exercise treadmill if you are still concerned.

I agree entirely with Dr Ng . You have no cause to worry if the murmur was merely incidental and you are:

• Otherwise active and fit
• Have no family history of sudden collapses or deaths
• Have no symptoms whatsoever

Occasionally murmurs could be secondary to something entirely unrelated, as in anemia, but usually you tend to have other symptoms as well i.e from the anemia.

You may want to touch base with your GP to ensure all is well apart from your heart. A normal ECG and echocardiogram is pretty reassuring from a heart point of view.

I agree with both Dr Julian Ng and Dr Nandakumar. Provided you have no symptoms, and both the ECG and echocardiogram were done properly and were found to be normal, there is no further action that you need to take from the heart point of view. Just continue to lead a healthy life-style and enjoy your life!
