Cardiotoxin
Cardiotoxin (pronunciation: /ˌkɑːrdi.oʊˈtɒksɪn/), also known as cardiac toxin, is a type of toxin that specifically affects the heart.
Etymology
The term "cardiotoxin" is derived from the Greek words kardia, meaning "heart", and toxikon, meaning "poison".
Definition
Cardiotoxin is a type of cytotoxin that is capable of causing damage to heart tissue. It is typically produced by certain types of snakes, such as the cobra, and is a component of their venom.
Effects
When introduced into the body, a cardiotoxin binds to the membranes of cardiomyocytes, or heart muscle cells, disrupting their function. This can lead to a variety of symptoms, including irregular heartbeat, arrhythmia, and potentially, heart failure.
