Abstract

BACKGROUND: To describe the national trends and outcomes of contemporary thrombectomy use for primary percutaneous coronary intervention (PCI) from 2016 to 2018.

METHODS: We queried the Nationwide Readmission Database (NRD) from January 2016 to December 2018 to identify patients who underwent primary PCI and thrombectomy. We conducted a multivariate regression analysis to identify variables associated with in-hospital mortality and stroke in patients undergoing primary PCI and those who underwent thrombectomy.

RESULTS: We identified 409,910 total hospitalizations who underwent primary PCI. Thrombectomy was used in 62,446 records (15.2%) with no change in the trend over the study period (p trend = 0.52). Thrombectomy was more utilized in patients who had more cardiogenic shock and use of mechanical circulatory devices. The overall incidence of in-hospital mortality and stroke were 5.6% and 1.1%, respectively. The incidence of in-hospital mortality (6.7% vs. 5.4%, p < 0.001) and strokes (1.3% vs. 1.0%, p < 0.001) were higher in the thrombectomy group. On multivariable regression analysis adjusting for high-risk features, thrombectomy was not independently associated with in-hospital mortality [1.036, 95% CI (0.993-1.080), p = 0.100], but was associated with a higher risk of stroke [OR 1.186, 95% CI (1.097-1.283), p < 0.001].

CONCLUSION: During primary PCI, thrombectomy was used in 1 of 6 cases, and its use has been stable over 2016-2018. The use of thrombectomy was associated with a higher risk of stroke, but not in-hospital death.
