【求助】JACC under review 60天，仍无结果

听说JACC从来拒稿或者修稿都很快的，2-5周。我现在已经投过去9周了，期间7周的时候给主编发了一封催稿信，当天就回复我，内容如下：I have now checked on the status of your paper. The review was delayed by what appears to be a spurious allegation that the manuscript had also been submitted to the American Heart Journal. We are awaiting the critique of one more reviewer. If we have not received this last review by next week, we will render a decision on the available information.

我回信说我们没有一稿多投，如有需要帮助，请告知我们并期待文章的消息。

我现在要做啥呢？虽然不急着要文章，继续等吗？
