Hi,
Welcome, this is Dr Sameer, cardiologist.
IHSS do follow a hereditary pattern and we advice such patients to be in regular follow up & do some tests. If your earlier tests have been fine, than it does not rule out possibility of having a heart issue in future.
If you are having
chest pain, I'll recommend you to go to the Emergency & at least do a ECG to see if anything is wrong.
For your knowledge, cardiac pain is non localized (i.e. it is diffused) & increase on exertion (with exercise like walking, running or
stress) & it is generally not relieved by traditional pain killers.
So yes, get yourself evaluated soon.
In future, despite of having a simple
echocardiogram, I'll advice you for a stress echo, which helps better in predicting chances of future cardiac events.
Thanks
Take care
