I've written a few times on this post about the shortness of breath and chest pain in walking not even far which has got steadily worse. After 2 ECG that's showed a problem along with an Echo showing Hypokinetic inferior wall my cardiologist was almost certain I had blocked arteries so I had a echocardiogram, I had no blocked arteries so an MRI was ordered along with a CTPA. Monday I was taken into hospital with severe chest pain. A marker for Troponin was 20 which on the second reading went up to 30 an indication of a heart attack. The problem is my ECG did not show I was having one so now no one will commit to what has happened. It leaves me waiting for the MRI. I feel very unwell my bloods fir my lupus have come back normal for me. Anyone else heard of this. One dr said ECG aren't always right another one took it has gospel. Feeling very confused. Any advice would be helpful. Stayed overnight in hospital. They have changed one of my tablets to help spasms in the heart and nitro lingual for under the tongue. Unstable angina they first said it was. Not feeling clear on the conclusion.
