Next step will probably be a stress test, and if that indicates any blockages a cath may be done and further procedures like stents or bypass may be indicated. I do know someone who had a score of 1100 and was apparently healthy and asymptomatic and his cardiologist went straight to a cath which led to an immediate double bypass. A lot depends not only on your husband's actual condition but on how aggressive the cardiologist is in his treatment approach. The anxiety and stress in this situation can be hard on the patient and on the spouse so make sure that you are aware of the mental affect and take care of yourselves. The important thing is that this was caught before he had any major event so that it can be fixed, Best of luck.
