Abstract:

Objective To investigate the relationship between the ratio of small and dense low-density lipoprotein cholesterol(sd-LDL-C)to high-density lipoprotein cholesterol(HDL-C)and the short-term prognosis of patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI). Methods A total of 218 AMI patients who underwent PCI in Hohhot Mongolian Hospital of Traditional Chinese Medicine from January 2020 to December 2023 were enrolled. The clinical data and preoperative laboratory determination results were collected,the levels of sd-LDL-C and HDL-C before PCI were determined,and the sd-LDL-C/HDL-C ratio was calculated. The patients were classified into good prognosis group(153 cases)and poor prognosis group(65 cases)based on the short-term(1 month)prognosis after PCI. Receiver operating characteristic(ROC)curve was used to evaluate the efficacy of various indicators in predicting the poor short-term prognosis of AMI patients after PCI. Results There was statistical significance in the proportions of myocardial infarction area,smoking history and hypertension between good prognosis group and poor prognosis group(P<0.05),while there was no statistical significance in the other clinical data between the 2 groups(P>0.05). There was statistical significance in the levels of low-density lipoprotein cholesterol(LDL-C),sd-LDL-C,HDL-C and sd-LDL-C/HDL-C ratio between poor prognosis group and good prognosis group(P<0.05),while there was no statistical significance in the other indicators between the 2 groups(P>0.05). Myocardial infarction area≥50%,smoking history,hypertension,elevated LDL-C,elevated sd-LDL-C,decreased HDL-C and elevated sd-LDL-C/HDL-C ratio were risk factors for the poor short-term prognosis of AMI patients after PCI(P<0.05). The areas under curves(AUC)of single and combined determinations of LDL-C,sd-LDL-C,HDL-C and sd-LDL-C/HDL-C ratio for predicting the prognosis of AMI patients were 0.651,0.868,0.850,0.919 and 0.934,respectively. Conclusions The sd-LDL-C/HDL-C ratio is associated with poor short-term prognosis in AMI patients after PCI,which can be used as one of the indicators for evaluating the short-term prognosis of AMI patients after PCI.
