question: Hi, may I answer your health queries right now ?  Please type your query here...  I have had ongoing chest pressure and SOB.  Recent CXR showed moderately enlarged heart and R atrium. Have a h/o of hypothyroidsm, currently not at theraputic level abd started BCP last month at age 36.  Could either of these have cause the heart problems? If not what could be the reason? BP is fine.
