September Morn,
Getting them to the hospital quickly is the best thing you can do. My husband avoided having a heart attack back in 2000, b/c I "threw" him in our vehicle and got him to the ER in about 5 - 7 minutes. They gave him medication that prevented a heart attack. He had some kind of clot, which they later took care of in surgery, after they transferred him to another hospital.

They can get on our last nerve everyday, but we still love them mightily.
With lots of prayers and hugs,
EJ
