He says the headaches typically occur between 34 timesday, mostly at night, each lasting minutes to 12 hours. He describes the pain as severe, stabbing, unilateral, and localized to the left periorbital region. He says he frequently notes increased tear production and conjunctival injection in the left eye and rhinorrhea during these headaches. He mentions that he had a similar 3-week episode of these same, frequent intermittent headaches 3 months ago which stopped completely until 1 month ago. He denies any seizures, loss of consciousness, nausea, vomiting, photophobia, or phonophobia. His past medical history is significant for stable angina secondary to coronary artery disease diagnosed on a stress echocardiogram 1 year ago. He reports occasional alcohol use, which he says precipitates the headaches, but denies any smoking or recreational drug use. The patient is afebrile, and his vital signs are within normal limits. A physical examination is unremarkable. A noncontrast computed tomography CT scan of the head is normal. Which of the following is the best abortive treatment for this patient?? A: Sumatriptan, B: Dihydroergotamine, C: High-flow 100 oxygen, D: Hydrocodone, E: Intranasal lidocaine,  <response>: This appears to be a question about choosing the best abortive treatment for a patient with cluster headaches. Based on the description, this patient is experiencing episodic cluster headaches characterized by frequent, severe, unilateral pain localized around the eye with associated autonomic symptoms like tearing and rhinorrhea. The headaches are precipitated by alcohol use. Importantly, the patient has a history of coronary artery disease, so we must choose an abortive therapy that is safe for cardiac patients.C: High-flow 100 oxygen
