OBJECTIVE To investigate the correlation between serum laminin (LN) level and the prognosis of acute heart failure (AHF). METHODS A total of 199 patients with AHF treated in Nantong First People's Hospital from March 2019 to November 2021 were included in this study. The patients were divided into the event group and the non-event group according to whether major adverse cardiovascular events (MACEs) occurred during hospitalization. We collected the baseline data of all patients and their LN levels were measured. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of LN for the occurrence of MACE in AHF patients during hospitalization. Multivariate Logistic regression analysis was used to screen the independent factors associated with the occurrence of MACE in patients with AHF. RESULTS Among 199 patients with AHF, 43 were in the event group and 156 were in the non-event group. The area under ROC curve of LN to predict MACE in AHF patients during hospitalization was 0.8144, 95% confidence interval (CI): 0.7433-0.8855, p < .0001, cutoff point = 77.9, specificity 58.33%, and sensitivity 88.37%. Multivariate logistic regression analysis showed that the independent factors associated with the occurrence of MACE in AHF patients were the increase of LN level (odds ratio [OR]: 1.020, 95% CI: 1.012-1.028), the decrease of ejection fraction (OR: 0.007, 95% CI: 0.000-0.362) and diastolic blood pressure (OR: 0.946, 95% CI: 0.913-0.981; p < .05). CONCLUSION The increase of LN level is independently correlated with the occurrence of MACE in AHF patients during hospitalization, which has the potential to be a serological indicator for poor prognosis in patients with AHF.
