Background: We explored the potential of mechanical thrombectomy (MT) for acute ischemic stroke patients at hospitals that perform percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) in the United States.
Methods: We analyzed nationally representative data between 2017 and 2020 to determine the numbers, characteristics, and outcomes of acute ischemic stroke patients admitted to hospitals that perform both primary PCI and MT, hospitals that perform primary PCI but not MT and hospitals that perform neither PCI or MT. Multiple logistic regressions were performed to evaluate the effect of hospital type on in-hospital mortality and discharge home (without palliative care).
Results: A total of 1,210,415, 1,002,950, and 488,845 acute ischemic stroke patients were admitted to hospitals that performed both primary PCI and MT, performed primary PCI but not MT, or performed neither PCI nor MT, respectively. Compared with hospitals that performed both PCI and MT, the odds of in-hospital mortality were lower in hospitals that performed PCI only (odds ratio (OR) 0.88 95 % confidence interval (CI) 0.86-0.91, p<0.001) and hospitals that performed neither PCI or MT (OR 0.85 95 %CI 0.82-0.89, p<0.0010). There was no significant difference in the odds of discharge home between the three types of hospitals.
Conclusions: Almost 37 % the patients with acute ischemic stroke are admitted to hospitals that perform primary PCI (but not MT) supporting strategies to increase the performance of MT in such hospitals as an option to increase rapid availability of MT in the United States.
