Supreme Court Justice Ruth Bader Ginsburg is "resting comfortably" after having heart surgery Wednesday morning, according to a release from the high court.
Ginsburg, 81, underwent a procedure to place a stent in her right coronary artery at the MedStar Heart & Vascular Institute in Washington, D.C. According to the release, Ginsburg began experiencing discomfort after doing routine exercise Tuesday night and was taken to the hospital. She is expected to be discharged in 48 hours.
Ginsburg told The New Republic in September she still works out with her trainer -- who she shares with fellow Supreme Court Justice Elena Kagan -- twice a week.
"I do a variety of weight-lifting, elliptical glider, stretching exercises, push-ups," Ginsburg said. "And I do the Canadian Air Force exercises almost every day."
But she has had her share of health problems, including two broken ribs in June 2012 and bouts with both colon and pancreatic cancer.
Despite the setbacks to her health and the calls of many who want her to retire so that President Barack Obama can appoint a new Supreme Court justice before the end of his term, Ginsburg told Elle in September she'll remain in her position as long as she feels she "can do the job full steam."
