Also, if Paul dies, Kathy's guilt,sorrow, and realistic assessment of her odds would put her in such a deep depression that I don't see how she can continue fighting. The body reacts to depression and this would not have a positive effect on her remission. Besides, Paul is key to the show. Oliver Platt has created as indelible a character in Paul as Laura Linney's Cathy. Having him 'come back' in after-death appearances is just not the same and won't have the same impact. Please, please have Paul recover from his heart attack.
