No reported mortality is directly associated with CH. However, patients with CH are at increased risk for self-injury during attacks, suicide attempts, alcohol use (and other forms of substance abuse), cigarette smoking, and peptic ulcer disease. Suicides have been reported in cases where attacks are frequent and severe. The intensity of the attacks often leads CH patients to miss time from activities such as work or school. Medications used may have side effects, including the unmasking of coronary artery disease.
