BOSTON (TheBlaze/AP) — Teresa Heinz Kerry, the wife of U.S. Secretary of State John Kerry and heir to a ketchup company fortune, was hospitalized in critical condition Sunday while on Massachusetts’ Nantucket Island then later flown to a Boston hospital.

Heinz Kerry arrived at Massachusetts General Hospital in Boston after doctors at Nantucket Cottage Hospital stabilized her, a spokesman for Kerry said.

Neither the family nor hospital officials had released any more details about her medical emergency or her condition Sunday night.

“The family is grateful for the outpouring of support it has received and aware of the interest in her condition, but they ask for privacy at this time,” the Kerry spokesman said.

Nantucket Police Lt. Jerry Adams said a call requesting medical aid was received just after 3:30 p.m. for a home on Hulbert Avenue, and an ambulance was dispatched. Online records show the property is connected to Heinz Kerry’s family.

Heinz Kerry is the widow of former U.S. Senator John Heinz, heir to the Heinz ketchup fortune. She married John Kerry in 1995.

Doctors treated her for breast cancer in December 2009.

She previously has said she found in late September that year that she had cancer in her left breast after having her annual mammogram.

A month later, she underwent lumpectomies on both breasts at a Washington hospital after doctors also discovered what they thought was a benign growth on her right breast.

That diagnosis was initially confirmed in postoperative pathology, but two other doctors later found it to be malignant.

In November 2009, Heinz Kerry had another pair of lumpectomies performed at Massachusetts General Hospital.

John Kerry has been at the Nantucket home since returning from nearly two-week around-the-world diplomatic trip to the Mideast and Southeast Asia in the pre-dawn hours of July 3.

Before his wife’s medical problem, he had planned to return to Washington on Monday and then co-host with Treasury Secretary Jack Lew high-level strategic and economic talks with senior Chinese officials on Wednesday and Thursday.

Kerry had also spoken of his desire to make his sixth trip to Israel as secretary starting at the end of the week. State Department officials said Kerry’s schedule is now influx pending developments with his wife’s health.
