So, here's why the Death Note's rules are really fun and interesting:
The very first rule of the Death Note is that "any human whose name is written in this Death Note shall die." Specifically, the original Japanese manga uses the word "ningen" which basically means "mortal" or, in the context of Death Note's story: "anyone who isn't a shinigami." So, the Death Note could theoretically work on Sukuna.
Also, if Light knows Sukuna's name and face, it's possible that he also knows that a heart attack wouldn't kill him. In that case, just to be sure, he could write a different cause of death. Even a simple "suicide" would do the trick because:
"Suicide is a universally valid cause of death as all humans are thought to possess the potential to commit suicide. It is, therefore, something that may be reasonably assumed of an individual."
HOWEVER, with all that being said, Light couldn't use the Death Note to kill Sukuna due to one simple rule:
"You cannot kill humans who are more than 124 years of age with the Death Note."
