Cardiotoxicity refers to the damage inflicted on heart muscle and other cardiac tissues, impacting cardiovascular function. As a significant concern across various therapeutic areas, this issue affects several drug classes, such as anticancer agents, antibiotics, and psychotropic medications. Identifying cardiotoxic effects early in drug development is crucial as the pharmaceutical landscape continues to evolve.

The Role of Zebrafish in Cardiotoxicity Research

Zebrafish (Danio rerio) have become essential models for studying drug safety, especially cardiovascular toxicity. Their utility is attributed to shared physiological traits with humans and the ability to undergo transparent development. This enables researchers to observe cardiac function in vivo rapidly.

Research has shown that zebrafish exhibit a high predictability in drug response, validating their role in cardiotoxicity assessments. Extensive similarities exist between the zebrafish and mammalian hearts, including specialized chambers, valves, and an intricate electrical system that ensures efficient function. Advanced imaging techniques, such as echocardiography, can be employed to noninvasively evaluate cardiac performance in zebrafish, allowing for simultaneous monitoring of multiple parameters.
