Cardiac magnetic resonance imaging of epicardial adipose tissue in patients with acute ST-segment eleva-tion myocardial infarction complicated by hypertension
Objective Epicardial adipose tissue(EAT)is closely related to coronary artery disease(CHD)and hypertension,and cardiac magnetic resonance imaging(CMRI)has been maturely applied in the assessment of myocardial infarction(MI).To discuss the difference in EAT by using CMRI in patients with ST-segment elevation myocardial infarction(STEMI)complicated by hypertension(HTN).Methods STEMI patients undergoneemergencypercutaneous coronary intervention(PCI)and CMRI(n=320)were chosen from Critical Care Unit in Affiliated Hospital of Xuzhou Medical University from Jan.2019 to Dec.2021.After exclusion,304 patients were divided into STEMI+non-HTN group(n=171)and STEMI+HTN group(n=133).The EAT volume(EATV)and EAT mass(EATM)were compared between 2 groups.Results EATV[(157.23±14.61)ml vs.(143.64±15.99)ml,P<0.01]and EATM[(161.33±15.1)g vs.(147.26±17.34)g,P<0.01]increased in STEMI+HTN group compared with STEMI+non-HTN group.The results of multi-factor Logistic regression analysis showed that EATV(OR=1.064,95%CI:1.039~1.086,P<0.01)and EATM(OR=1.069,95%CI:1.032~1.084,P<0.01)were independent risk factors in STEMI complicated by HTN(P<0.05).The results of ROC curve analysis showed that the optimal cutoff value of EATV was 151.3 ml,AUC was 0.779(95%CI:0.725~0.834,P<0.01),and the optimal cutoff value of EATM was 155.35 g and AUC was 0.791(95%CI:0.738~0.844,P<0.01).Conclusion EATV and EATM are independent risk factors in STEMI patients complicated by HTN,and they have a higher predictive value.
