I think you know the answer to this question my friend. You're assuring yourself and your family of another procedure that could be wholly avoidable.
I've heard it is very difficult to quit smoking, but you've obviously done it once before. Get back on the horse again and you'll be the better for it. And stay away from people who smoke - it will only tempt you to succumb to this terrible habit.

You're kidding, right? Smoking is a HUGE risk factor for CAD. You had a scare 1 1/2 years ago and you started smoking again, prepare for another scare. You really need to stop, this could escalate until it's too late.
