New Data from the DanGer Shock Randomized Control Trial, Published in The New England Journal of Medicine, Confirms the Long-Term Survival Benefit of the Impella CP Heart Pump

MADRID, Aug. 31, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) – Late breaking clinical science data, presented at the European Society of Cardiology (ESC) Congress today and simultaneously published in the New England Journal of Medicine (NEJM), finds at up to 10 years, when compared to standard care, routine use of Impella CP^® in patients who have had a heart attack with cardiogenic shock leads to an absolute mortality reduction of 16.3% (95% CI: 0.54 to 0.92)¹. When compared to the control arm at 10 years, Impella CP patients gained an average of 600 additional days alive (95% CI: 235 – 966 days)¹.

These new findings from the long-term follow up of patients in the investigator-initiated DanGer Shock randomized controlled trial (RCT) were presented at ESC by the trial's principal investigator, Jacob Møller, MD.

"The long-term data from the DanGer Shock RCT released today validates the original findings and confirms that the survival benefit of Impella CP is durable and increases year-over-year," said Navin Kapur, MD, chief medical and scientific officer for heart recovery, J&J MedTech.

The absolute mortality reduction of 16.3% at up to 10 years is an increase from the initial 6-month data, which found routine use of Impella CP reduced the absolute risk of mortality by 12.7%². Impella CP is the first mechanical circulatory support (MCS) proven in an RCT to provide short-term and long-term survival benefits in patients with cardiogenic shock due to STEMI. The American College of Cardiology (ACC) and American Heart Association (AHA) upgraded Impella to a class 2a guideline based on the original DanGer Shock RCT data presented at ACC in May 2024. The trial enrolled 360 participants at 14 sites in Denmark, Germany and the United Kingdom between 2013-2023².

Approximately 750,000 people in the United States experience an ST-elevation myocardial infarction (STEMI), an acute heart attack, each year² and the overall incidence rate of cardiogenic shock in patients with STEMI is up to 10%³. Cardiogenic shock (CS) is the leading cause of in-hospital mortality in patients with STEMI⁴.

Impella, the world's smallest heart pump, is inserted into the heart to temporarily take over the heart's pumping function, allowing the heart to rest and recover while maintaining the flow of oxygenated blood throughout the body. This therapy allows patients to return to their life and families with their native heart and experience an equal – or improved – quality of life.
