Lethal ventricular tachycardia triggered after femoral fracture repair in an obese man with insulin-resistant diabetes.

Abstract:

:An obese man (height, 178 cm; weight, 160 kg; body mass index, 50.5 kg/m2) with a history of recurrent ventricular tachycardia (VT), cardiomyopathy, coronary sclerosis, and insulin-resistant diabetes suffered a right femur fracture in a vehicular accident. His fracture was repaired the following day, but shortly after surgery, his serum potassium (K+) level increased, presumably due to K+ leakage from the injured muscles, leading to persistent VT and death. An autopsy revealed severe cardiac hypertrophy, moderate coronary sclerosis, and histological findings of myocardial hypercontraction, but not myoglobin-related renal failure, pulmonary thrombosis, lipid emboli, or inflammation. The hyperkalemia was not corrected by glucose-insulin infusion and led to the death of the patient due to the preexisting cardiomyopathy, coronary sclerosis, and a predisposition to VT. In addition to the autopsy, the analysis of the clinical course was indispensable for determining the cause of death as hyperkalemia-related VT.
