Abstract：Objective To explore the risk factors for intramyocardial hemorrhage(IMH)in patients with ST-segment elevation myocardial infarction(STEMI)after primary percutaneous coronary intervention(pPCI)and the impact of IMH on left ventricular remodeling.Methods A total of 159 patients who underwent pPCI at the Cardiovascular Center of Beijing Friendship Hospital between October 2019 and March 2022 were prospectively included.The patients were divided into two groups based on cardiac magnetic resonance(CMR)examination within 1 week after surgery:IMH group(n=66)and non-IMH group(n=93).All patients were followed up and reexamined CMR after 6 months.To compare the baseline data,left ventricular remodeling and other related data between the IMH group and the non-IMH group,multi-factor logistic regression was used to identify the risk factors for IMH.Results The the peak level of cTnT and the level of hs-CRP and in the IMH group were higher than those in the non-IMH group,and the difference was statistically significant(P＜0.05).The ROC showed the predictive value of IMH in patients with STEMI.Hs-CRP and cTnT peak:ROC were 0.66 and 0.76 respectively(P＜0.05).Conclusion Hs-CRP and cTnT peak are independent risk factors for IMH in STEMI patients and have certain predictive value for the occurrence of IMH.
