Tawny Kitaen Died From Heart Disease with Opioids a Contributing Factor

Tawny Kitaen, the late actress who starred in "Bachelor Party" and whose personal life was filled with radical ups and downs, died from heart issues ... this according to her autopsy.

According to the Orange County Coroner's Office, Tawny's official cause of death is dilated cardiomyopathy ... the most common type of heart disease.

Other contributing factors include clogged arteries, antidepressants, sedatives, Tylenol, nerve pain medication and opioids.

TMZ broke the story ... Tawny died May 7 in Newport Beach, CA and cops told her family there was nothing found at the scene suggesting alcohol, drugs or pills were a factor in her death, nor were there any signs she took her own life.

Tawny's death came not long after her father passed, and her brother told us their father's loss was simply too much for her to handle.

Her family and close friends recently gathered to remember her one last time with an intimate celebration of life in Newport ... and she's been cremated.

Tawny lived a pretty storied life -- she acted in films like the one mentioned above, and has credits in flicks like "The Perils of Gwendoline" and "After Midnight" -- as well as several hit TV series, such as "Santa Barbara," "The New WKRP in Cincinnati," "Eek! the Cat," "Hercules," "Moms Anonymous," and many, many more over the years.

And, Tawny famously was featured in some music videos ... notably Whitesnake's "Is This Love," and "Here I Go Again."
