Abstract:
Objective To investigate preoperative myocardial enzymes and realative influencing factors in Stanford B type aortic dissection.Methods From Jan.2004 to Sep.2013,151 consecutive patients with Stanford type B aortic dissection were admitted to hospital,aged from 31 to 76 average:(51.51 ± 10.90)year sold.Ninty-five healthy people with similar age and sex were taken as the control group.Fasting venous blood collected more than 12h was collected,myocardial enzymes indexes such as CK,CKMB,LDH,HBDH were measured by Roche modular automatic biochemical analysis system.Primary entry tear and extent of aortic dissection was measured by Toshiba Aquilion ONE 320 slice CT.Degree of aortic valve insufficiency was measured by Philips Sonos 5500 Color Doppler ultrasonic diagnostic apparatus.Results Compared with control group,the level of myocardial enzymes (LDH,HBDH) of aortic dissection group increased significantly(P ＜ 0.01).part myocardial enzymes indexes(CK,LDH,HBDH) of acute stage group existed difference(P ＜ 0.05).Myocardial enzymes indexes only CK existed difference between acute stage group and subacute stage group and chronic stage group(F =18.72,P =0.000),no difference between subacute stage group and chronic stage group.LDH,HBDH of each sub group of aortic dissection group were higher than that of control group,P ＜ 0.01.Trough correlation analysis,CK negatively correlated with disease course of aortic dissection and patients sex [(r =-0.446 ; P =0.000) ; (r =-0.303 ; P =0.000)],CKMB negatively correlated patients sex [(r=-0.203;P=0.020)],LDH negatively correlated with patients sex [(r =-0.171 ;P =0.049)],positively with left ventricular end-diastolic diameter and left ventricular end-systolic diameter [(r =0.202 ; P =0.022) ; (r =0.271 ; P =0.002)].HBDH positively correlated with left ventricular enddiastolic diameter and left ventricular end-systolic diameter [(r =0.385 ;P =0.002) ; (r =0.515 ; P =0.000)],negatively with degree of aortic insufficiency [(r =-0.528 ;P =0.006)].Conclusions Myocardial enzymes rise in preoperative Stanford B aortic dissection,more representing skeletal muscle injury.Be affected by stage of aortic dissection,lower limb skeletal muscle injury aggravates more seriously in acute stage group persists entering the sub acute stage.
