Galantamine, used for Alzheimer's disease, can cause heart problems like bradycardia and heart block. Patients on cholinesterase inhibitors require cardiac screening, including ECG, to prevent adverse effects.

Area of Science:

  • Neurology
  • Cardiology
  • Pharmacology

Background:

  • Alzheimer's disease is a progressive neurodegenerative disorder.
  • Cholinesterase inhibitors, such as galantamine, are a common treatment for Alzheimer's.
  • Cardiac side effects of cholinesterase inhibitors are a potential concern.

Observation:

  • A 77-year-old male patient on galantamine for Alzheimer's developed sudden bradycardia and complete atrioventricular block.
  • The patient's cardiac condition necessitated pacemaker implantation.
  • Galantamine treatment was continued post-pacemaker implantation.

Findings:

  • Following pacemaker implantation and continued galantamine treatment, the patient experienced resolution of cardiac symptoms.
  • The patient demonstrated cognitive improvement on a standardized scale.

  • This case highlights a potential link between galantamine and severe cardiac events.
  • Implications:

    • Cholinesterase inhibitors may pose risks for cardiac arrhythmias.
    • Pre-treatment cardiac screening, including ECG and potassium levels, is crucial for patients initiating cholinesterase inhibitor therapy.
    • Further research is warranted to elucidate the mechanisms and prevalence of cardiac adverse events associated with cholinesterase inhibitors.
