LOS ANGELES, JAN. 6 -- An autopsy performed on basketball great Pete Maravich revealed his death was the result of heart disease, but the exact nature of the problem may not be determined for two weeks, a spokesman for the Los Angeles County coroner's office said today.

"The cause of death is attributed to heart disease, the nature of which has yet to be determined," said Bob Dambacher. "Additional microscopic analysis will be conducted to determine the exact cause of death.

"Microscopic slides will be made and the analysis completed in a week or two."

Maravich, the greatest scorer in college basketball history, collapsed and died Tuesday after playing in a pickup basketball game at a church near Pasadena. He was 40.

Maravich, one of the game's top attractions and a member of the Hall of Fame, had finished playing a half-court game with friends at the Church of the Nazarene when he fell suddenly. He was taken to St. Luke Hospital in Pasadena where doctors tried unsuccessfully to revive him.

The former Louisiana State star spent most of his NBA career with the Atlanta Hawks and New Orleans Jazz. In recent years, he had spoken widely on nutrition and fitness. At last year's NBA old-timers' game in Seattle, he appeared to be in better shape than most of the former players, but he recently told friends that a nerve problem in his right arm and shoulder had kept him off the court for six months.

Maravich played three seasons at LSU under his father, Press, who died last year. His mother earlier committed suicide and Maravich had referred to her death at recent public appearances.

A memorial service is scheduled for Saturday at First Baptist Church in Baton Rouge, La.
