ST-segment elevation myocardial infarction (STEMI) is a common cardiovascular emergency for which timely reperfusion therapies are needed to minimize myocardial necrosis. The aim of this study was to investigate the impact of the COVID-19 pandemic and reorganization of chest pain centers (CPC) on the practice of primary percutaneous coronary intervention (PPCI) and prognosis of STEMI patients. This single-center retrospective survey included all patients with STEMI admitted to our CPC from January 22, 2020 to April 30, 2020 (during COVID-19 pandemic in Wuhan), compared with those admitted during the analogous period in 2019, in respect of important time points of PPCI and clinical outcomes of STEMI patients. In the present article, we observed a descending trend in STEMI hospitalization and a longer time from symptom onset to first medical contact during the COVID-19 pandemic as compared to the control period (4.35 h versus 2.58 h). With a median delay of 17 minutes in the door to balloon time (D2B), the proportion of in-hospital cardiogenic shock was significantly higher in the COVID-19 era group (47.6% versus 19.5%), and major adverse cardiac events (MACE) tend to increase in the 6-month follow-up period (14.3% versus 2.4%). Although the reorganization of CPC may prolong the D2B time, immediate revascularization of the infarct-related artery could be offered to most patients within 90 minutes upon arrival. PPCI remained the preferred treatment for patients with STEMI during COVID-19 pandemic in the context of timely implementation and appropriate protective measures.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) is a fatal cardiovascular emergency requiring rapid reperfusion treatment. During the coronavirus disease-2019 (COVID-19) pandemic, medical professionals need to strike a balance between providing timely treatment for STEMI patients and implementing infection control procedures to prevent nosocomial spread of COVID-19 among health care workers and other vulnerable cardiovascular patients. OBJECTIVES: This study evaluates the impact of the COVID-19 outbreak and China Chest Pain Center's modified STEMI protocol on the treatment and prognosis of STEMI patients in China. METHODS: Based on the data of 28,189 STEMI patients admitted to 1,372 Chest Pain Centers in China between December 27, 2019 and February 20, 2020, the study analyzed how the COVID-19 outbreak and China Chest Pain Center's modified STEMI protocol influenced the number of admitted STEMI cases, reperfusion strategy, key treatment time points, and in-hospital mortality and heart failure for STEMI patients. RESULTS: The COVID-19 outbreak reduced the number of STEMI cases reported to China Chest Pain Centers. Consistent with China Chest Pain Center's modified STEMI protocol, the percentage of patients undergoing primary percutaneous coronary intervention declined while the percentage of patients undergoing thrombolysis increased. With an average delay of approximately 20 min for reperfusion therapy, the rate of in-hospital mortality and in-hospital heart failure increased during the outbreak, but the rate of in-hospital hemorrhage remained stable. CONCLUSIONS: There were reductions in STEMI patients' access to care, delays in treatment timelines, changes in reperfusion strategies, and an increase of in-hospital mortality and heart failure during the COVID-19 pandemic in China.
