Nifedipine-induced hypotension and mesenteric ischemia.

We have presented a case in which nifedipine-induced hypotension in a patient receiving beta blocker and nitrate therapy precipitated mesenteric angina, leading to emergency exploratory celiotomy. Although paradoxic angina is an unusual complication of this antianginal therapy, it should be considered in any patient who has acute abdominal pain and hypotension while receiving this therapeutic regimen.
