However, there is little published information concerning the depth of the impact on the clinical management and outcome following AMI.Methods: We enrolled patients with AMI who received urgent primary percutaneous coronary intervention at the Beijing Tiantan Hospital (Beijing, China) between December 1, 2019 and April 10, 2020. Patients were divided into 2 cohorts, the pre-COVID-19 group (from December 1, 2019 to January 31, 2020) and during-COVID-19 group (from February 1, 2020 to April 10, 2020) for analysis. The door-to-balloon (D to B) time, total hospitalization stay (days) and coronary care unit (CCU) hospitalization days were calculated. New York Heart Association heart functional class (NYHA class), re-hospitalization and death ratio in patients were assessed between the two cohorts.Results: A total of 148 AMI patients were enrolled in this study comprising 53 patients pre-COVID-19 group and 95 patients during-COVID-19 group. Patients with AMI during-COVID-19 group had longer symptom onset to hospital time (4.5 [2.0â 9.3] vs 3.0 [2.0â 5.0] hours, p = 0.013) and D to B time (96 [74â 119] vs 67 [52â 81] minutes, p < 0.001); the D to B time shortened during the study period. The two cohorts did not have significantly different number of hospitalization days, re-hospitalization rates, peak cTnI, BNP or death rates. For the one-year follow-up, the patients in the during-COVID-19 group were classified as NYHA class IIIâIV more frequently (9 [9.7%] vs 0 [0%], p=0.004).Conclusion: The COVID-19 pandemic significantly affected one measure of critical care of patients with AMI, NYHA classification, which may have resulted in increased medical expenses.Keywords: acute myocardial infarction, COVID-19 pandemic, in-hospital outcome, New York Heart Association heart functional class |
