Neurologic Complications After Cardiac Transplant

Area of Science:

• Neurology
• Cardiology
• Transplant Medicine

Background:

• Cardiac transplantation is a vital treatment for end-stage heart failure.
• Neurologic complications are frequent post-transplant, impacting patient outcomes.
• Known risk factors include medication toxicity, infections, and metabolic issues.

Purpose of the Study:

• To determine the incidence of neurologic complications in adult cardiac transplant recipients.
• To identify common neurologic issues following heart transplantation.

Main Methods:

• Retrospective analysis of medical records from 70 adult cardiac transplant patients (2004-2016).
• Data collected included demographics, neurologic symptoms, examination findings, lab results, imaging, and treatments.
• Evaluation focused on identifying and categorizing neurologic complications.

Main Results:

• The overall incidence of neurologic complications was 30%.
• Encephalopathy was the most common complication (12 patients), often secondary to other neurologic issues.
• Other observed complications included posterior reversible encephalopathy syndrome (7 patients), neuropathic pain (4), tremor (3), ischemic cerebrovascular accident (2), and drop foot (1).

Conclusions:

• Neurologic complications are a significant concern in cardiac transplant recipients.
• The study confirms a 30% incidence of neurologic complications, with encephalopathy being the most prevalent.
• Posterior reversible encephalopathy syndrome frequently precedes the development of encephalopathy.
