Swiss cardiac surgeon Diana Rezer has reclaimed her Guinness World Records title for the largest collection of heart-shaped objects, amassing 3,200 items over 25 years and unseating the previous record holder from the United States. The achievement was officially verified in the commune of Zollikon in the canton of Zurich, infohub.kz reports.
According to a press release from Guinness World Records, the doctor's passion began about 25 years ago, when she completed a cardiac surgery internship during her medical studies and decided to devote her life to the specialty. After learning of her choice, friends, colleagues and patients began giving her heart-themed souvenirs.
Rezer first entered the Guinness World Records in 2010 with a collection of 775 items and held the lead for 14 years. In February 2024 the title passed to American Susan West, but the Swiss physician knew her own collection was far larger and submitted a new application in April 2026. The presence of all 3,200 items was officially confirmed by two independent witnesses, Peter Hartmaier and Ralf Pöhner.
About half of the exhibits were gifts from loved ones and patients, while the surgeon found the rest herself around the world. Among the items are a Rubik's Cube, a working stethoscope, a fragment of the Berlin Wall, paintings, lamps and household trinkets, as well as six tattoos on Rezer's own body. The doctor jokingly calls her hobby a contagious "heart condition" and dedicates the record to the prevention and timely treatment of cardiovascular disease.
