I believe the answer is:
cardiac
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">heart-related</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for cardiac that I've seen before include "of hearts" , "Appertaining to the heart" , "Of the heat, perhaps illness" , "Relating to the heart" , "Sort of surgery" .)
