Interferencija fibrilacije atrija s terapijom implantabilnog kardioverterskog defibrilatora u bolesnika sa zatajivanjem srca i smanjenom ejekcijskom frakcijom. (Croatian)

Interference of Atrial Fibrillation with Implantable Cardioverter Defibrillator Therapy in Patients with Heart Failure and Reduced Ejection Fraction. (English)

Implantable cardioverter defibrillators (ICD) are an important therapeutic option in reducing mortality due to ventricular arrhythmias in patients with heart failure with reduced ejection fraction. Atrial fibrillation (AF) is often present in these patients and may interfere with ICD therapy by inducing inappropriate and appropriate shocks. This issue is important because both types of shock increase mortality in patients with ICD. The strategies to minimize the rate of ICD shocks induced by AF include the optimization of ICD programming, pharmacological therapy for rate or rhythm control, and ablation of AF or atrioventricular junction ablation. In this review, we describe the interference of AF with ICD therapy, examine the impact of this interference on survival, and discuss the strategies for its reduction. [ABSTRACT FROM AUTHOR]

Implantabilni kardioverterski defibrilatori (ICD) važna su terapijska opcija u smanjenju smrtnosti zbog ventrikularnih aritmija u bolesnika sa zatajivanjem srca i smanjenom ejekcijskom frakcijom. Fibrilacija atrija (FA) često je prisutna u ovih bolesnika i može interferirati s ICD terapijom izazivanjem neprikladnih i prikladnih šokova. Ovo je važno pitanje jer oba tipa šoka povećavaju smrtnost u bolesnika s ICD-om. Strategije za smanjenje učestalosti ICD šokova izazvanih FA-om uključuju optimizaciju programiranja ICD-a, farmakološku terapiju za kontrolu frekvencije ili kontrolu ritma, te ablaciju FA-a ili atrioventrikularnoga spoja. U ovome preglednom radu istražujemo interferenciju FA-a s terapijom ICD-a, analiziramo utjecaj te interferencije na preživljenje i raspravljamo o strategijama za njezino smanjivanje.
