Background: Limited data is available regarding in-hospital outcomes of patients undergoing high-risk percutaneous coronary intervention (HR-PCI) with Impella with and without a prior history of coronary artery bypass grafting (CABG).
Methods: We performed a retrospective study from the Nationwide Inpatient Sample from year 2016 to 2020. We identified patients who underwent Impella and percutaneous coronary intervention on the same day and excluded those with cardiogenic shock. Subsequently, we stratified them into those with and without prior CABG.
Results: During the study period, 18 925 patients underwent HR-PCI. Among these, 2043 (10.8%) patients had prior CABG. Patients without prior CABG had a higher percentage of acute coronary syndrome at presentation (62.7 vs 56.1%, P = 0.008). The proportion of females was significantly higher in those without prior CABG (32.4 vs 21.7%, P < 0.001). On multivariate analysis, there was no statistically significant difference in the in-hospital mortality (5.8% in CABG vs 8.5% in non-CABG, P = 0.52). Patients without prior CABG had higher rates of acute kidney injury, major bleeding, and blood transfusions. There were no significant differences in rates of cardiac arrest, ventricular arrhythmias, acute stroke, coronary dissections, and coronary perforations. Those without prior CABG had a longer duration of hospitalization (6.8 vs 9.3 days, P < 0.001) and higher hospital charges ($292 267 vs $322 206, P < 0.035).
Conclusion: Our study highlights that a history of previous CABG does not increase the risk of in-hospital mortality in patients undergoing Impella-assisted HR-PCI but is associated with reduced rates of complications.
