Do small-conductance Ca2+-activated K+-channels contribute to ventricular repolarization in human heart failure?

Resultado clave

Small-conductance Ca2+-activated K+-channels do not play an important role in ventricular repolarization in the human failing heart.

Puntos clave

• The aim is to determine the role of small-conductance Ca2+-activated K+-channels in ventricular repolarization during heart failure.
• Assessed the contribution of small-conductance K+-channels (SK-channels) to repolarization in failing human hearts.
• Compared findings with previous studies on SK-channels and ventricular repolarization.
• The results do not confirm previous findings that suggested a significant role for SK-channels in repolarization.
• Observed no substantial impact of SK-channels on ventricular repolarization in the context of heart failure.
