Fibrinolysis Therapy Combined with Deferred PCI versus Primary Angioplasty for STEMI Patients During the COVID-19 Pandemic: Preliminary Results from a Single Center.

introductionThe efficacy of fibrinolysis therapy with deferred percutaneous coronary angioplasty (FPCI) versus primary angioplasty (PPCI) during the coronavirus disease 2019 (COVID-19) pandemic is unclear when medical quarantine is needed. PATIENTS AND

methodsAcute ST segment elevation myocardial infarction (STEMI) patients underwent PPCI after finishing the screening protocol from January 23, 2020 to June 10, 2020 while FPCI was applied when COVID-19-confirmed cases reoccurred in Beijing near our hospital from June 11, 2020 to July 20, 2020. The door-to-balloon time (DTB) or door-to-needle time (DTN) as well as in-hospital adverse clinical outcomes were compared between the two groups. A propensity score-matched (PSM) analysis was performed to diminish the potential influence of confounding factors on the clinical outcomes.

resultsA total of 126 STEMI patients underwent PPCI after finishing the screening protocol and 17 patients received FPCI before PSM. Patients who received FPCI were younger than patients who underwent PPCI (50.8±14.0 versus 64.1±14.2 years, p=0.001), and chronic kidney disease (CKD) was less common in FPCI patients than in patients who underwent PPCI (0% versus 24.6%, p=0.024). The DTN was significantly shorter than DTB (25.8±4.2 versus 61.1±10.7, p=0.000) before PSM. The DTN was significantly shorter than DTB (26.9±4.2 versus 64.9±23.6, p=0.000); however, the incidence rate of in-hospital ischemia and bleeding adverse clinical outcomes were comparable between the two groups after PSM.

conclusionFibrinolysis therapy combined with deferred PCI can reduce the ischemia time and has a similar in-hospital adverse clinical outcome rate compared with patients who underwent primary PCI during the COVID-19 pandemic.
