Abstract Aims This study evaluated how well serial pulse pressure (PP) and PP adjusted by the vasoactive inotropic score (VIS) predicted venoarterial extracorporeal membrane oxygenation (VA‐ECMO) weaning success and clinical outcomes in acute myocardial infarction complicated by cardiogenic shock (AMI‐CS) patients. Methods and results A total of 213 patients with AMI‐CS who received VA‐ECMO between January 2010 and August 2021 were enrolled in the institutional ECMO registry. Serial PP and VIS were measured immediately, 12, 24, and 48 h after VA‐ECMO insertion. PP adjusted by VIS was defined as PP/√VIS. The primary outcome was successful VA‐ECMO weaning. Successful weaning from VA‐ECMO was observed in 151 patients (70.9%). Immediately after VA‐ECMO insertion, PP [successful vs. failed weaning, 26.0 (15.5–46.0) vs. 21.0 (12.5–33.0), P = 0.386] and PP/√VIS [11.1 (5.1–25.0) vs. 6.0 (3.1–14.2), P = 0.118] did not differ between the successful and failed weaning groups. Serial PP and PP adjusted by VIS at 12, 24, and 48 h after VA‐ECMO insertion were significantly higher in patients with successful weaning than those with failed weaning [successful vs. failed weaning, 24.0 (4.0–38.0) vs. 12.5 (6.0–25.5), P = 0.007 for 12 h PP, and 10.1 (5.7–22.0) vs. 2.9 (1.7–5.9), P < 0.001 for 12 h PP/√VIS]. The 12 h PP/√VIS showed better discriminative function for successful weaning than 12 h PP alone [area under the curve (AUC) 0.80, 95% confidence interval (CI) 0.72–0.88, P < 0.001 vs. AUC 0.67, 95% CI 0.57–0.77, P = 0.002]. Patients with a low 12 h PP/√VIS (≤7) had higher rates of in‐hospital mortality (44.4% vs. 19.8%, P < 0.001) and 6 month follow‐up mortality (hazard ratio 2.41, 95% CI 1.49–3.90, P < 0.001) than those with a high 12 h PP/√VIS (>7). Conclusions PP adjusted by VIS taken 12 h following VA‐ECMO initiation can predict weaning from VA‐ECMO more successfully than PP alone, and its low value was associated with a higher risk of mortality in AMI‐CS patients.
