Can you take nicorette (nicotine gum) and nitro-dur?

I suppose: One would expect that a patient needing nitrates would be more likely to have complications from any nicotine compound which would promote vasospasm. However, if the choice were nicorette (nicotine gum) vs. Cigarettes, i would prefer the nicorette (nicotine gum).

Yes: For a long while, the manufacturers put on their package insert that people with heart disease shouldn't use nicotine replacement therapy (NRT). However, it is entirely clear that the greatest risk to health in people with heart disease is continued tobacco smoking, and NRT is clearly safest. What I would NOT do is have a cigarette anywhere near using a nicotine patch or gum. Good luck quitting.
