EXCLUSIVE INTERVIEW with the pop icon’s daughter –DAVY JONES was ex­periencing severe chest pains in the weeks before his death – but he passed off the life-threatening symp­toms as indigestion!

And THAT’s what really killed the beloved Mon­kees singer, who died at age 66 on Feb. 29 despite having no ap­parent health prob­lems.

“My father had just had all of these tests and every­thing came back great,” his grieving daughter Talia told The ENQUIRER.

“He was told his heart was like a 25-year-old’s.

“So when he continued to have pains in the chest area, he nev­er thought it was anything but a bad case of heartburn.

“In fact, he needed more ex­tensive testing to know what was really going on.”

The most common symptom of coronary artery disease is chest pain, but it is often mis­taken for indigestion or heart­burn.

Meanwhile, the Martin County medical examiner con­firmed March 2 that the cause of death was an “abnormal heart rhythm” caused by “cor­onary artery atherosclerosis” – a hardening or narrowing of the arteries.

“If the doctors had discovered this in time, Davy could have been saved,” said an insider. “He didn’t have to die!”

“Of course there was stress,” said Talia. “What stressed him was just living the lifestyle he did – liter­ally going from one country to the next, one state to the next.

“He was always try­ing to do so much and please everybody.”
