LOS ANGELES — Hip-hop pioneer Heavy D died from a blood clot in his leg that traveled to his lungs after a long flight from Europe, officials said Tuesday.

The Los Angeles County Coroner said deep leg vein thrombosis led to the pulmonary embolism that took the life of the 344-pound entertainer at age 44 last month.

"Yes, (the flight) is the connection. He had reportedly been in London for about six weeks and had returned to LA within the preceding week or so," Craig Harvey, chief coroner investigator, told the Daily News.

Investigators said medications the rapper was taking did not contribute to his collapse outside his Beverly Hills condominium building Nov. 9.

A coroner’s spokesman earlier told The News that Heavy D, whose real name was Dwight Arrington Myers, visited a doctor the day before he died, complaining of flu-like symptoms.

A cousin said Heavy D thought he had "a touch of pneumonia" after his travels in England.

The "Now That We Found Love" singer was conscious and talking to first responders but experiencing difficulty breathing when he was rushed to a hospital the day he died.

Raised in Mount Vernon, N.Y., Heavy D rose to stardom in the 1990s as the frontman for Heavy D & the Boys — the group behind a string of hits including "Nuttin But Love."

He also performed the theme song for the 1990s comedy TV series "In Living Color," and took the stage most recently at the BET Awards last fall.

Heavy D eventually segued into acting and scored a cameo role as a security guard in the recently released film "Tower Heist," starring Eddie Murphy and Ben Stiller.

"Hev had great love for his family and friends; he was a kind and giving spirit who extended and shared himself with everyone who crossed his path," his grieving family said in a statement before his burial.

They said his "most important triumph" was as a father to his 13-year-old daughter Xea.

"Hev's love for his daughter Xea was profound. She was the center of his life, his heart, his soul," they said. "She embodied every phenomenal attribute that he brought to this world."

Rap mogul Sean (P. Diddy) Combs and the Rev. Al Sharpton attended his private memorial service.

"He was a wonderful human being, who inspired and paved the way for a hip-hop generation," Combs said in a statement.
