I am a 58 year old woman and am experiencing pain in my mid-chest with the pain radiating to my back and shoulders plus trouble breathing. During intra-venous stress test, I experienced severe chest pain and a major drop in bp. Systolic was 30. My doctor sent me for an angiogram. I was told that the bp drop indicated probable blockage but it would need to be 70% or greater for stent to be placed. After test, I was told that no major blockage had been found and that I should follow up with my regular doctor. However I am still having the pains and breathing problems. Especially when I am more active or stressed out than normal. For example walking more than a half mile and I'll have an episode. Or disagreement with my husband and I'll have an episode. What questions should I ask my doctor at my follow-up to get to the bottom of this? I also have rheumatoid arthritis, hypertention and sleep apnea to name a few. My appointment is Thursday.
