Inflammation-Associated Atrial Fibri l lation and
Recurrent Arrhythmia
• Atrialfibrillation(AF)isthemostcommonarrhythmiainclinicalpractice,affectingupto10%ofthepopulationover60yearsold.Itsoccurrenceriseswithageandleadstoheartfailure,peripheral embolism and stroke, and its mortality remains high despite effectiveanticoagulation. In addition, about 20% of all cases of AF remain undiagnosed and itsrecurrencerangesfrom40to50%,despitetheattemptsofelectricalcardioversion,ablationand the administrationof antiarrhythmic drugs. Therefore, every effort shouldbemade topreventarrhythmiasintheclinicalsetting.
• Many factors and disorders increase the risk of AF, including obesity, diabetes, male sex,chronic low-grade inflammatory rheumatic diseases, symptomatic skeletal pathologies,chronicosteomyelitis,hypertension,coronaryarterydisease,chronickidneydisease, sepsis,obstructivesleepapnea,high-levelphysicaltraininginactiveorformercompetitiveathletes,subclinicalhyperthyroidism,cancer,cigarettesmoking,NSAIDsandalcoholconsumption.
• AmongpotentialpathogenicfactorsofAF,inflammatoryimbalancemayplayacriticalrole.Notsurprisingly, thepresenceof inflammation in theheart and systemic circulation canpredictthe onset of AF and AF-associated thromboembolism in the general population; and AFrecurrenceinpatientsaftercardiacsurgery,cardioversion,andcatheterablation.Moreover,inflammatory cells and mediators modulate calcium homeostasis and connexins therebyalteringcardiactissuestructureandconduction,whichinturnleadstostructuralremodelingoftheatriaandincreasedvulnerabilitytoAF.
