Therapeutic implications of atrial fibrillation mechanisms: can mechanistic insights be used to improve AF management?

abstract：BACKGROUND:During reperfusion of ischaemic myocardium, Na+/H+ exchange promotes recovery from acidosis resulting in an accumulation of intracellular Na+. This leads to calcium overload via Na+/Ca2+ exchange and might result in cell necrosis contributing to reperfusion injury. METHODS AND RESULTS:We assessed whether HO...
