Shock Following Percutaneous Coronary Intervention As A Man-ifestation Of Diabetes Insipidus

The shock syndrome following percutaneous coronary intervention (PCI) is a life-threatening complication, accompanied by poor outcomes. The most com-mon causes of this problem are bleeding and severe left ventricular systolic dysfunction; although rare complications could happen, they are still challeng-ing. In this article we reported a 47-year-old man who suffered from complica-tions following PCI, manifested as unexplained shock, which was resistant to conventional management. Overestimating the role of the patient’s underlying disorder as the cause of the hypotension led to delay in diagnosis and treatment; however, obtaining a thorough familial history revealed diabetes insipidus (DI) as the most probable cause of the hypotension despite normal electrolyte levels at the time of admis-sion. The patient dramatically responded to DI management. Persistent hypotension or shock after PCI could result from an unusual or rare etiology. Precise history taking and attention to clinical findings are essential for an accurate diagnosis and timely treatment of this life-threatening condition indeed
