Cardiovascular Safety Assessment

Cardiovascular safety assessment refers to the evaluation of potential adverse effects of drugs or other interventions on the cardiovascular system. LeadQuest Biotech’s Cardiovascular safety Assessment involves studying cover various aspects of drug effects on the cardiovascular system, including electrophysiological activity, cytotoxicity, myocardial structure, and cardiovascular function, thereby ensuring comprehensive assessment of drug cardiovascular safety. It is an essential component of preclinical and clinical drug development to identify and mitigate any risks of cardiovascular-related adverse events.
