As a common clinical adverse reaction,pharmacogenic cardiotoxicity is a severe challenge for drug development and clinical treatment.The evaluation of pharmacogenic cardiotoxicity is the focus of current research,and early evaluation is difficult with its complex and diverse mechanisms,varying clinical manifestations,and numerous influencing factors.Biomarker is an important index to evaluate cardiotoxicity.This article summarizes a variety of cardiotoxicity biomarkers and other potential biomarkers that have been reported so far,hoping to find biomarkers with strong specificity and high sensitivity,so as tocontribute to the evaluation on cardiac safety of drugs.
