How concerned is Macbeth about his wife? What does this reveal about their relationship now?

A servant enters with the news that the enemy has rallied a thousand men but Macbeth sends him away, scolding him for cowardice. After calling for his servant Seyton to help him put on his armor, Macbeth demands the doctor’s prognosis about Lady Macbeth. The doctor replies that she is “not so sick” but troubled with visions (39). In some way or other, she must cure herself of these visions—an answer that displeases Macbeth. Macbeth, however displeased, is not concerned about his wife. She now is not important in his life. Macbeth is consumed with paranoia and power that he no longer really cares about his wife's fate.
