I Have Had A Oblation. It Was One Year Ago.

I have had a oblation. It was one year ago. Recently I have been stressed with so many things I am working on at one time. I think about these task all the time morning noon night . I am having hyperventilation, panic systems, shortness of breath. Right now I have taken a zanax, and my symptems have subsided greatly. I just want to know that this is not all being caused by condition of my heart that could result in a heart attack
