NEW YORK — The oldest daughter of Eric Garner, the black man whose dying calls of “I can’t breathe’’ after being placed in a chokehold by a police officer became a protest chant across the country, has been hospitalized after a heart attack, her mother said on Monday.

Erica Garner, 27, was in a medically induced coma, her mother, Esaw Snipes, said in a telephone interview.

After her father’s death on Staten Island in 2014, Erica Garner campaigned for police accountability, demanding justice for not only her father but also for others who were killed during encounters with police.

She has sought answers from former president Barack Obama and castigated New York City Mayor Bill de Blasio over police matters. In 2016 she campaigned on behalf of Senator Bernie Sanders for president, introducing him at a rally in South Carolina.

She was hospitalized on Saturday night, her mother said, after an asthma episode caused a heart attack.

Snipes said her daughter had a heart attack not long after giving birth four months ago. During the pregnancy, doctors told her she had an enlarged heart, which the pregnancy had put a strain on.

Snipes declined to name the hospital where her daughter is being treated.

“Right now, the family is just praying and asking for everyone to keep her in their prayers,’’ said Snipes, who is the widow of Eric Garner.

Eric Garner was killed in July 2014 when plainclothes officers from the New York Police Department were arresting him for selling single untaxed cigarettes.
