We analysed 5717 patients in the J-PVAD from 1 February 2020 to 31 December 2022, to compare the incident risks of device-related problems and all-cause mortality within 30 days after PVAD introduction based on flow capacities of first-line PVAD (low: Impella 2.5\/CP, n = 5375; high: Impella 5.0\/5.5, n = 342). The overall incidence of major device-related problems, including haemolysis, major bleeding, kidney injury, sepsis, and pump stop, was 13%, 21%, 7%, 3%, and 1%, respectively. The all-cause mortality rate was 34%. The incident risks of haemolysis [hazard ratio (HR) 0.38, 95% confidence interval (CI) 0.24\u20130.58], kidney injury (HR 0.32, 95% CI 0.18\u20130.57), and pump stop (HR 0.38, 95% CI 0.16\u20130.91) were lower in patients with high-flow PVAD compared with those with low-flow PVAD. The risks of major bleeding or sepsis did not differ significantly between groups. The risk of all-cause mortality was lower in patients with high-flow PVAD compared with those with low-flow PVAD (HR 0.79, 95% CI 0.65\u20130.96).<\/jats:p>\n               <\/jats:sec>\n
