LOS ANGELES (AP) _ Frank Sinatra was stricken by a heart attack at his Beverly Hills estate two hours before he died in the emergency room, his death certificate showed.

The certificate signed by Dr. Jeffrey Helfenstein, the entertainer's doctor for five years, provided only stark detail about Sinatra's final hours. It was obtained Monday by The Associated Press.

Two hours prior to death, the entertainer was at home when he was stricken with acute myocardial infarction, commonly known as a heart attack, and paramedics called to the residence rushed him to Cedars-Sinai.

His wife, Barbara, was dining with friends at a nearby restaurant when she was notified and she went to the hospital and stayed at his side until death.

Thirty minutes before his death at 10:50 p.m. on May 14, Sinatra suffered cardiorespiratory arrest _ his heart and lungs stopped functioning _ while in the Cedars-Sinai Medical Center emergency room, the county Department of Health Services document showed.

Sinatra was 82.
