Conservative firebrand Andrew Breitbart, a blogger and commentator who frequently said his life's goal was to "destroy the institutional left," died of heart failure stemming from coronary disease, the Los Angeles coroner ruled Friday. 

In a statement obtained by NBC News, coroner spokesman Craig Harvey said Breitbart died of natural causes. A toxicology screening showed no prescription or illicit drugs in Breitbart's system. A blood alcohol level of 0.04 percent was found in his system, a negligible amount. 

Breitbart showed no signs of trauma, and foul play is not suspected, Harvey said. The case has been closed.

Breitbart died at the age of 43 on March 2 at Ronald Reagan UCLA Medical Center after collapsing while walking his dog near his home in Los Angeles.
