Whitney Houston's full autopsy report is expected to be released in a few weeks and it may provide a physical description of the singer's heart, officials said.
The Toxicology results showing how much cocaine and other drugs were in Houston's system will be included, according to the Associated Press.
The Los Angeles County Coroner's office revealed Houston's cause of death this week, as drowning and effects of atherosclerotic heart disease and cocaine use. Houston, 48, died in a bathtub in her hotel suite at the Beverly Hilton hotel in California on Feb. 11.
Houston died on the eve of the 2012 Grammys. She was to make an appearance at Clive Davis' pre-Grammy party that day. Houston was buried a week later in New Jersey.
Assistant Chief Coroner Ed Winter told the AP that the full report may include test results and physical descriptions of the singer's heart. It will show whether Houston suffered a heart attack, Winter said.
Houston's autopsy report is currently being compiled.
Winter wasn't able to tell the news organization if Houston's heart had any discoloration, suggesting she had a heart attack before slipping underwater, because he hadn't any access to the findings.
The singer's death has been ruled as an accidental drowning combined with the contributing factors of heart disease and cocaine use.
The AP also reported that police will also use the autopsy report to complete their investigation into Houston's cause of death. However, police aren't expected to publicly release the file.
