I am a 34 year old female with a strong family history of heart disease. At 31, I underwent all tests including an coronary angiogram which came back fine. I have been tested for GERD etc as well (negative). To date, I am still experiencing chest pressure/pain, shortness of breath, nausea, dizziness, severe upper back pain (at times) etc. My cardiologist has now prescribed CCB's instead of betablockers along with nitroglycerin. In January, he wants to repeat many of the tests that I had underwent a few years back because of a "questionable" stress test. It had something to do with (pardon my ignorance) inconsistencies in the ST waves. My question(s) to you then are these: Could something worse be developing unbeknownst to me? Is this all in my head? Can microvascular disease of the heart be this debilitating? Can you explain ST waves in general terms?
My blood pressure is on the lower side. I am 5'5, approximately 140lbs, light smoker, and a non drinker.
Please advise. Thank you.
