Impact of the Coronavirus Disease-2019 Outbreak Period on ST-Segment Elevation Myocardial Infarction Cases, Treatment, and Prognosis
(A, B) The estimated means of number of ST-segment elevation myocardial infarction (STEMI) cases per Chest Pain Center (CPC) per week and the estimated means of time from symptom onset to first medical contact (S-to-FMC) (in hours) before and during the outbreak, in Hubei and in other provinces. (C, D) The decrease of proportion of STEMI cases undergoing primary percutaneous coronary intervention (PPCI) and the increase of those undergoing thrombolysis during the coronavirus disease-2019 (COVID-19) outbreak. (E) The estimated odds ratios of the independent variable “COVID-19 Outbreak Period” (January 24, 2020 to February 20, 2020) and corresponding confidence intervals in logistic regression models with 8 intermediate and endpoint outcome variables. OR = odds ratio; Wk = week.
