Abstract:
Objective To investigate the changes of the electrocardiograms (ECG) and the cardiac markers in patients with acute insular infarction,and analyze the relationship between them and the prognosis.Methods A total of 202 patients with acute middle cerebral artery territory infarction (patients group) and 150 control subjects (control group) was selected in this study.Patients included insular infarction (insular infarction group,136 cases),non-insular infarction (non-insular infarction group,66 cases),left-side insular infarction(71 cases) and right-side insular infarction(65 cases).ECG recordings and plasma cardiac troponin I (cTnI),creatine kinase-MB (CK-MB) were measured and compared.Death in 6 months was followed-up.Results There was significant difference in the incidence of abnormal changes of ECG and plasma cTnI,CK-MB increasing between patients group and control group (P <0.01).The incidence of abnormal changes of ECG and fatality rate were higher in insular infarction group than those in non-insular infarction group [80.88%(110/136) vs.46.97%(31/66) and 11.76% (16/136) vs.3.03% (2/66),P < 0.05 or < 0.01].The incidences of ectopy and prolonged QT were higher in right-side insular infarction patients than those in left-side insular infarction patients [44.62%(29/65) vs.11.27% (8/71),P <0.01 ; 55.38% (36/65) vs.35.21% (25/71),P < 0.05].The incidences of sinus bradycardia and ST segment deviation were higher in left-side insular infarction patients than those in right-side insular infarction patients [22.54%(16/71) vs.7.69%(5/65),P < 0.05 ;47.89%(34/71) vs.13.85% (9/65),P < 0.05].The increased rates plasma cTnI and CK-MB level were mainly seen in insular infarction [insular infarction group:47.79% (65/136),34.56% (47/136); non-insular infarction group:4.55% (3/66),1.52% (1/66),P < 0.01].The incidence of plasma cTnI increasing in right-side insular infarction patients was higher than that in left-side insular infarction patients [67.69%(44/65) vs.29.58%(21/71),P< 0.05].There was no significant difference in the incidence of plasma CK-MB increasing between left-side insular infarction patients and right-side insular infarction patients(P > 0.05).The fatality rates in plasma cTnI,CK-MB increasing patients were higher than those in normal plasma cTnI,CK-MB patients [16.18% (11/68) vs.5.22% (7/134),P <0.05;29.17% (14/48) vs.2.60% (4/154),P <0.01].Conclusions The effects of acute hemispheric cerebral infarction on heart are mainly associated with destruction of insula.Patients with insular infarction have more abnormal changes of cardiac markers and ECG,which is correlated with poor prognosis.
