JACC: Associate Editor Celina Yong, MD, interviews author Jacob Eifer Møller, PhD about his DANGER SHOCK paper presented at AHA and published in JACC. The DanGer Shock trial demonstrated reduced mortality in patients with STEMI-related cardiogenic shock treated with a microaxial flow pump (mAFP). This secondary analysis assessed whether age affected survival benefits. Mortality increased incrementally with age, and age was independently associated with outcome. Spline analysis suggested that the risk of mortality was higher in the standard-care group for patients below 77 years, whereas patients aged 77 or older had a higher predicted risk in the mAFP group. Thus, elderly patients may not attain the same benefit from routine treatment with a mAFP as younger patients.
