Methods: A total of 383 patients with different thrombotic burden STEMI admitted to our hospital from January 2019 to December 2020 were included, and were divided into no-reflow group (n=55) and control group (n=328) to analyze the related factors through clinical data and postoperative score evaluation. Results: Univariate analysis showed that age, sex, hypertension, diabetes, low-density lipoprotein cholesterol, ultrasound suggested wall motion abnormality, coronary pre-PCI myocardial troponin I (cTnI) level, anticoagulant drug use time, pre-PCI slow flow, pre-PCI transmural myocardial infarction, pre-PCI left ventricular dysfunction, pre-PCI heart function classification, PCI balloon time, PCI catheter type, post-PCI high-sensitivity cTnI level, post-PCI bleeding, post-PCI blood pressure drop, post-PCI total cholesterol level, and post-PCI heart function presenting low-pump failure are closely related to the occurrence of no-reflow phenomenon. Multivariate Logistic regression model verified that age (OR=1.034, 95%CI=1.007~1.062), anticoagulant drug use time (OR=4.873, 95%CI=1.914~12.41), and pre-PCI TICI grade (OR=0.183, 95%CI=0.048~0.696) were independent risk factors for no-reflow event (P<0.05). Conclusion: Age, anticoagulant drug use time, and pre-PCI TICI grade can be used as high-risk factors for post-PCI no-reflow event in patients with different thrombotic burden. Clinical doctors should strengthen monitoring and intervention measures for these patients to reduce the incidence of no-reflow events after PCI.Keywords: ST-segment elevation myocardial infarction; percutaneous coronary intervention; no-reflow phenomenon; related factorsIntroduction: The no-reflow phenomenon is a rare but serious complication of percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). It can lead to poor prognosis and even death. The purpose of this study is to explore the risk factors for no-reflow events after PCI in patients with different thrombotic burden.Methods: A retrospective analysis of 243 patients with STEMI who received PCI was conducted. Patients were divided into low, medium, and high thrombotic burden groups according to the pre-PCI thrombotic burden. The correlation between demographic and clinical characteristics and the occurrence of no-reflow events was analyzed.Results: Among the 243 patients, 24 (9.9%) had no-reflow events after PCI. The incidence of no-reflow increased with the increase of thrombotic burden (P<0.05). Multivariate regression analysis showed that age (OR=1.076, 95%CI: 1.022-1.134, P<0.05), anticoagulant drug use time (OR=2.997, 95%CI: 1.864-4.818, P<0.05), and pre-PCI thrombolysis in cerebral infarction (TICI) grade (OR=2.706, 95%CI: 1.174-6.235, P<0.05) were independent risk factors for no-reflow events after PCI.Conclusion: Age, anticoagulant drug use time, and pre-PCI TICI grade are high-risk factors for no-reflow events after PCI in patients with different thrombotic burden. Clinical doctors should pay attention to these factors and adopt targeted monitoring and intervention measures to reduce the incidence of no-reflow events after PCINo-reflow events after PCI can have serious consequences and can lead to increased morbidity and mortality in patients. Therefore, it is essential to identify the risk factors for this condition and take appropriate measures to prevent it.The current study highlights the importance of age, anticoagulant drug use time, and pre-PCI TICI grade as high-risk factors for no-reflow events after PCI in patients with different thrombotic burden. These findings suggest that clinical doctors should pay attention to these factors when performing PCI and adopt targeted monitoring and intervention measures to reduce the risk of no-reflow events.Age has been identified as a risk factor for no-reflow events in previous studies. This could be due to the fact that older patients may have more severe comorbidities and a greater likelihood of having underly。
