I'm sorry to hear about your father Kim, but then again, its a blessing that with today's technology, heart problems are easily treatable. Don't worry. Hopefully everything will be alright. My aunt had 3 major blockages 2 years ago and suffered from a heart attack. We were extremely worried and thought she wouldn't make it, but with faith in God and lots of prayers, she did. She had an open heart surgery and thank God, she's been just fine for 2 years now after the operation.

Edit: YAY! Congrats!
