question: I was admitted to hospital with dizziness and pressure in chest and neck. Mainly through shoulder. I did not pass stress test but EKG and echo were good. Could there be a possibility of blockages even though all blood work and test were good? Dr. Said next step would be to have heart cath. I was released from hospital to follow up with cardiologist. I also have lupus and was told that inflammation may be cause of problem. I am at a loss and terrified to have heart cath. Thank you for any advice.
