Pre-operative leukocytosis: a potential poor prognosis risk factor in cardiac device implantation: a case report

subject

description

Introduction. Despite the benefits of the implantation of cardiac rhythm management devices cardiac implantable electronic device (CIED) infection is an emerging problem New debate emerged about the unclear role of the pre-operative alteration of pro-inflammatory parameters, such as leukocytosis, in the development CIED infection and/or heart failure, and its consequent impact on the timing of ICD implantation/reimplantation. Case report. A 65 years old patient with a history of Diabetes Mellitus (DM) type II, ventricular and supraventricular arrhythmias, chronic myocardial ischemia, heart failure was admitted to hospital.Healthcare workers opted for ICD implantation despite the presence of a persistent leukocytosis with normothermia. Five days later the implantation, patient showed fever and heart failure; blood culture resulted positive for Staphylococcus Aureus. Patient died for sepsis syndrome due to a cardiac device-related infection after a few days, despite the device extraction. Discussion. Cardiac device implantation remains a necessary surgical procedure in order to reduce sudden cardiac death’s rate in patients with heart failure. Leukocytosis is a new potential poor prognosis risk factor. The relationship between pro-inflammatory markers’, such as CRP and white blood cell count, and device implantation is still not entirely clear. Pro-inflammatory markers could facilitate an infection development; recent study hypothesized that these markers could promote the development of heart failure. Conclusion. leukocytosis could represent a poor prognosis risk factor favoring the development of CIED infection and/or heart failure
