This bibliometric study analyzed global research trends in extracorporeal membrane oxygenation (ECMO) for cardiogenic shock from 1990–2024. Using 701 publications from 55 countries, the authors mapped collaborations, influential institutions, and evolving research themes. Major topics include postcardiotomy shock, extracorporeal cardiopulmonary resuscitation (ECPR), acute myocardial infarction–related shock, and ECMO bridging to transplant. Research focus has shifted toward predictive scoring systems, standardized protocols, and long-term patient outcomes.
