Echocardiography Study On Cardiac Function In Patients With Non-ischemic Cardiac Stroke

Objective: Understanding of echocardiographic evaluation of left ventricularfunction in ischemic stroke and transient ischemic attacks in patients with applicationsituation; To evaluation of non-cardiac ischemic stroke patients with left cardiacstructure and function changes, for stroke prevention and improve prognosis to furtherprovide a theoretical basis.Methods: A retrospective analysis of2011January to December in LiaoningProvince people’s Hospital intraneural department within the continuous hospitalizationfor ischemic stroke/TIA in patients with clinical data, in order to echocardiographicdata complete non-cardiogenic stroke/TIA patients as a case group.In the same period,and hospitalization for vertigo with complete echocardiographic examination results topatients as control group.Application of echocardiographic evaluation in patients withleft cardiac structure and function. Application of echocardiographic evaluate in patientswith left cardiac structure and function. On left cardiac function and ischemicstroke in relation of single factor and multiple factors analysis.Results: In ischemic stroke and235patients with TIA, including cardiogenicstroke patients with49cases of non-cardioembolic ischemic stroke,186patientssuffered from vertigo, over the same period hospitalized patients in the control group of64cases.Cardiac ischemic stroke patients in all were ultrasound heartbeat graph(including evaluation of cardiac structure and heart function).Non-cardiogenic stroke in186patients,67.7%(126/186) of patients undergoing cardiac structure ultrasoundexamination,46.8%(87/186) of patients with simultaneous cardiac structure and heartfunction in ultrasound evaluation. In126patients with cardiac structure ultrasonicdisplay:77.8%patients (98/126) visible changes of left ventricular structure, mainly asa left ventricular thickness thickness of interventricular septum and left ventricularposterior wall thickness (left ventricular enlargement in2cases only); followed by left atrial dilatation change31%(39/126).The case group and the control group ofultrasound heartbeat graph results also showed increased left ventricular thicknesschange is the most common, the two group were81.6%(71/87),48.4%(31/64), and agroup of left ventricular thickness ratio was significantly higher than that of controlgroup (81.6%vs48.4%,（x~2=17.03, P＜0.05); Secondly, two groups of left atrialenlargement ratio respectively in26cases (29.9%,26/87),9cases (14.1%,9/64), thecase group than control group (29.9%vs14.1%,（x~2=4.33, P＜0.05).Cardiac functionultrasonography revealed: case group and the control group had mitral A wave increasesquickly, respectively in50cases (57.5%,50/87) vs30patients (46.9%,30/64), twogroups were not significant difference (P＞0.05); E peak decreases or increases quickly,E/A value decreases or the same fashion with increasing LA elevation change, a groupof19.5%(17/87), the ratio is higher than that of control group6.3%(4/64); reducedleft ventricular ejection fraction of cases there are2cases, are large area cerebralinfarction,0cases of the control group.Multivariate Logistic regression analysis showed, adjusted for age,blood pressure, blood glucose, blood lipid, carotid atherosclerotic factors,ultrasonic heartbeat graph shows the changes of cardiac structure that theleft ventricular thickness increases {OR=2.232,95%Cl (1.518~3.283); P<0.05}, left atrial diameter expanding {OR=0.855,95%Cl (0.770~0.949); P<0.05} and stroke are related to the occurrence.Conclusion: Thickness of interventricular septum and left ventricularposterior wall thickness increases as the non cardiogenic stroke patientswith the most common ultrasound heartbeat of cardiac structure change,followed by left atrial enlargement.Both of them are predictors of anindependent risk factor of stroke.Some non cardiogenic stroke patients havecardiac diastolic function.Therefore, it is necessary for patients withischemic stroke and cardiac function evaluation.
