The key features are feelings of detachment, hopelessness, avoidance of activities, nightmares about having another heart attack, being jumpy and easily startled. These symptoms began after a traumatic event of having a heart attack and are most consistent with post-traumatic stress disorder. Acute stress disorder occurs within 4 weeks of a trauma. Major depression disorder would not be specifically tied to the traumatic event. Alcohol withdrawal is unlikely given he has decreased his drinking. Midlife crisis would not explain his specific symptoms.A: Post-traumatic stress disorder
