Dear RyanB,
I am sorry to hear about your CP and SOB. I think seeing a cardiologist is a good idea. However, given that you are 24 years old I don't think that blockages in the heart arteries are very likely. Though, it is possible for valve problems or weakening of the heart muscle to cause such symptoms. However, before considering such conditions, are you overweight or deconditioned (out of shape). If so these factors could be playing a part in the symptoms you are describing.
The echocardiogram will be very helpful, in that it will be able to identify any structural abnormalities with your heart that could explain your symptoms. This is an ultrasound which evalutes the valves and pumping function of the heart.
It is also possible that some of the symptoms you are experiencing are related to the medication you are taking. I would discuss this further with your doctor to see if he/she agrees and would consider another medical regimen. Hope you feel better.
Thanks for your question,
CCF-MD-KE
