Garry Shandling died from a blood clot in his heart, coroner's officials said Tuesday, more than seven months after the comedian's unexpected death. A report by Los Angeles' coroner's officials released Tuesday states the fatal clot occurred after the comedian developed blood clots in his legs, a condition known as deep vein thrombosis, the AP reports. The comedian had not been feeling well during a trip to Hawaii, the report stated. Shandling died March 24 after calling paramedics to his home. Los Angeles coroner's officials had delayed issuing their determination of what killed the 66-year-old until after a review of his medical records and toxicology tests were completed. The toxicology results found only a therapeutic amount of Xanax and some cold medication in his system. (More Garry Shandling stories.)
