I have been getting treatment for several years now, so my symptoms are less frequent than they were, but I still have multiple episodes of symptoms every day, mostly chest pressure/pain and shortness of breath, though I also get nausea with them sometimes.

Before I was diagnosed, I had significant chest pressure and pain, starting either a few inches under my armpit below my left breast or central under my breastbone, and radiating as it intensified, into my back and up into my neck and jaw. I was getting 20-30 episodes a day, some as long as an hour and other just a few minutes, and taking 8-10 doses of sublingual nitroglycerin a day.

In May 2022, I was given the Neovasc coronary sinus reducer at Mayo. Since then, with the reducer and additional treatment, I have more like 5-6 episodes of spasms and take 1-2 doses of nitro a day.

My symptoms happen now frequently when exercising, but also just when sitting.

Many people with microvascular dysfunction or coronary artery spasms don't necessarily have symptoms during ECGs and echos, so nothing shows up on those. Sometimes nothing shows up in any test except the provocative angiogram. But it is heart related . . .
