Current situation of acute ST-segment elevation myocardial infarction in a county hospital chest pain center during an epidemic of novel coronavirus pneumonia

Abstract

Our object was to examine how the pre- and post-pandemic COVID-19 impacted the care of acute ST-segment elevation myocardial infarction (STEMI) patients in county hospitals. Using January 20, 2020, as the time point for the control of a unique coronavirus pneumonia epidemic in Jieshou, 272 acute STEMI patients were separated into pre-epidemic (group A, n = 130) and epidemic (group B, n = 142). There were no significant differences between the two groups in terms of mode of arrival, symptom onset-to-first medical contact time, door-to-needle time, door-to-balloon time, maximum hypersensitive cardiac troponin I levels, and in-hospital adverse events (P > 0.05). Emergency percutaneous coronary intervention (PCI) was much less common in group B (57.7%) compared to group A (72.3%) (P = 0.012), and the proportion of reperfusion treatment with thrombolysis was 30.3% in group B compared to 13.1% in group A (P < 0.001). Logistic regression analysis showed that age ≥76 years, admission NT-proBNP levels ≥3,018 pg/ml, and combined cardiogenic shock were independent risk factors for death. Compared with thrombolytic therapy, emergency PCI treatment further reduced the risk of death in STEMI. In conclusion, the county hospitals treated more acute STEMI with thrombolysis during the COVID-19 outbreak.
