Prayers Needed

Edit:  My grandpa is having surgery tonight to clear a blockage to his heart.  I'm not sure what all the surgery entails, but as far as I know, it's a pretty common surgery and should go as planned.  I'm not sure if I will get updated again tonight or not, so I will update tomorrow on his status.  Thanks for your prayers!

My grandfather on my Mom's side had a heart attack this weekend.  He's use to being in pain, so he didn't think anything of it.  He had it on Saturday night, but went all day Sunday saying his chest hurt and he just had a cold.  My Grandma finally called the Dr on Monday Morning and they took him in.  The doctor said he had suffered a heart attack on Saturday night and that is why his chest has been hurting.  They won't know more until later this afternoon, but I'm praying that everything will be alright.  Any prayers you can throw our way would be greatly appreciated!
