Abstract：Objective To evaluate coronary microcirculation obstruction(MVO)in hypertensive patients using multimodal magnetic resonance imaging.Methods A total of 145 patients diagnosed with hypertension in our hospital from October 2023 to October 2024 were randomly included.Multimodal magnetic resonance imaging included conventional cardiac cine sequence,late-gadolinium enhanced(LGE)delayed phase scan,and feature tracking technique.MVO was diagnosed based on delayed phase scan and the patients were divided into observation group(n=68)and control group(n=77).The measurement parameters included global longitudinal strain(GLS),global radial strain(GRS),global circumferential strain(GCS)of left ventricle,as well as LS,RS,and CS of the apical,middle,and basal segments,left ventricular mass index(LVMI),and so on.Results Compared with control group,the observation group showed significant increases in average systolic blood pressure,duration of hypertension,LVMI,GLS,and basal LS(P<0.05).Multivariate logistic regression showed that increased GLS was only independent risk factor to MVO in hypertensive patients(OR=3.032,95%CI:2.426-4.032,P<0.001).ROC curve showed that area under the curve of GLS for MVO diagnosis was 0.856(95%CI:0.756-0.923,P<0.001).Conclusion Magnetic resonance imaging based on feature tracking technology measuring left ventricular GLS has good accuracy in hypertensive patients for the diagnosis of MVO,which can be used as an alternative technique for LGE delayed phase scan,improving the safety of examination.
