NCT02167165

Brief Summary

This study tested the hypothesis that response to digoxin is modulated by single Nucleotid Polymorphism (SNP):

  • Multi Drug Resistance (MDR1) gene haplotypes and Solute carrier organic anion transporter family member 1B3 (SLCO1B3) gene Polymorphism and their role in the response to treatement.
  • Aldosterone synthase (CYP11B2) gene and sodium channel, voltage-gated, type V alpha subunit gene (SCN5A) correlated with atrial fibrillation and their roles in response to digoxin.

Outcome Measures

Primary Outcomes (1)

  • Correlation between the response to digoxin and the genotypes of the patients

    In the current study we aimed at outlining the different MDR-1, SLCO1B3, CYP11B12 and SCN5A genotypes in a sample of Tunisian patients, suffering from AF and taking digoxin, to assess the role of SNPs in affecting serum digoxin concentrations, and studying the consequences on patients' clinical outcome. Patients will be monitored for 24 hours in an intensive care unit;

    24 hours

Secondary Outcomes (1)

  • Rhythm and Rate control

    24 hours

Other Outcomes (1)

  • Arterial hypotension Bradycardia (HR <45 bpm) Other (chest pain, allergic reaction……)

    24 hours

Study Arms (1)

Digoxin and AF

Patients consulting the emergency deprtment (ED) for AF and receiving Digoxin treatment

Drug: Digoxin Injection

Interventions

Patients consulting the ED for Acute onset AF received 0.5 mg digoxin by oral root

Digoxin and AF
