I'm so sorry to hear this has happened to your DH and the stress it is causing you & your family.
We went thru this a cpl of yrs ago. My DH had a heart attack and they didn't even know it! He went to the hospital by ambulance, as his heart rate was 32. I knew he had a heart attack, but they couldn't find 'it'. 2 months later he had a stress test done at our great cardio's office, he didn't fare well and they sent him to a wonderful heart hospital for further testing. He had three areas that were in bad shape, 1 in very bad shape. They set him up to have stents put in.
We had a special dr do the stents, he did a great job. I can't remember the title they give to the drs that perform this procedure, sorry - brain isn't working on all cylinders today.
They finally dx my DH w/ having a heart attack. As much as I like being 'right', that was one time I would have liked to be wrong!
My DH has since retired - due to many health conditions- but he did go back to work after the HA, the stents and several other 'things' came up.
I know you are scared, I've been there. Pls try to relax as much as you can. You will have things to discuss and plan w/ the drs. Diet, exercise, possible procedures, etc.
It feels like you can't do this, I've been there, too. You will be able to do it. Why? Bc you love your DH and he will need your help.
You also have all of us here and we will be praying for your DH and you. Keep praying and we will, too. We are w/ you. And you are not alone.
God bless. Alice.
