Complications
Although myocardial infarction during anaphylaxis is uncommon, it will become more frequent as the general population ages and allergic reactions of senescence become more prevalent. Cardiac ischemia may be triggered by hypotension associated with anaphylaxis, or the hypertension and tachycardia that often follows the administration of epinephrine (adrenaline).
Individuals with previous anaphylactic reactions are at higher risk for recurrence.[53] However, the severity of a previous reaction does not necessarily predict the severity of a subsequent one.[39]
Treatment involves immediate administration of epinephrine (adrenaline), crucial for outcome and prognosis.
If the inciting allergen is unknown, clinical and laboratory tests should be performed to determine the cause. Patients must avoid this allergen in the future.
