KCNA5 and myocardial infarction: Of note, while the Kv1.5 block by vernakalant was demonstrated in Kv1.5-expressing HEK293 cells (Eldstrom et al., 2007) and a rat model of myocardial infarction (Fedida et al., 2005), there has been no evidence yet for Kv1.5 block by vernakalant in human atrial myocytes (Wettwer et al., 2013).
