Abstract:
Objective To analyze the prognosis and influencing factors of patients with acute myocardial infarction(AMI)complicated with cardiogenic shock(CS)under extracorporeal membrane oxygenation(ECMO)support.Methods Retrospective analysis of the clinical data of ECMO supported coronary angiography and percutaneous coronary intervention(PCI)treatment for AMI complicated with CS patients who visited the department of emergency medicine of the Second Hospital of Hebei Medical University from December 2018 to December 2021,including gender,age,body mass index(BMI),past history(smoking history,coronary heart disease,diabetes,hypertension,hyperlipidemia,cerebrovascular disease),acute physiological and chronic health evaluationⅡ(APACHEⅡ),vasoactive-inotropic score(VIS),the worst auxiliary examination indicators within 24 hours before ECMO[arterial lactate acid,white blood cell count(WBC),cardiac troponin I(cTnI),alanine transferase(ALT),total bilirubin(TBil),creatinine(Cr),serum potassium(K+),left ventricular ejection fraction(LVEF)],time from onset to PCI,coronary angiography results(involved anterior descending branch,circumflex branch,right coronary artery,three-vessel lesions,left main artery lesions),whether to use intra aortic-balloon counterpulsation(IABP)and continuous renal replacement therapy(CRRT).Patients were divided into survival and death groups based on the prognosis after 30 days of onset.Univariate analysis was used to compare the differences in the above indicators between the two groups with different prognoses,Logistic regression analysis was used to analyze the independent risk factors affecting the prognosis of AMI patients with CS under ECMO support coronary angiography and PCI treatment,and the receiver operator characteristic curve(ROC curve)was drawn to evaluate the predictive value of risk factors on patient prognosis.Results Out of 39 patients,21 cases(53.8%)survived and 18 cases(46.2%)died.Compared with the survival group,the VIS score,lactate acid,time from onset to PCI,involvement of the circumflex artery,three-vessel disease,and left main artery lesions significantly increased in the death group(all P＜0.05).Logistic regression analysis showed that lactate acid and three-vessel lesions were independent risk factors affecting the 30-day prognosis of AMI patients with CS[odds ratio(OR)and 95%confidence interval(95%CI)were 1.845(1.018-3.342)and 107.171(1.307-8 785.901),all P＜0.05].ROC curve analysis showed that lactate acid and three-vessel lesions has predictive value for the prognosis of AMI combined with CS patients undergoing ECMO supported coronary angiography and PCI treatment,the area under the ROC curve(AUC)were 0.756 and 0.752,95%CI were 0.601-0.911 and 0.588-0.916,P value were 0.007 and 0.008.When the cut-off value of lactic acid was 5 mmol/L,the sensitivity and specificity of predicting the prognosis of AMI combined with CS patients undergoing coronary angiography and PCI treatment were 94.1%and 57.1%,respectively.Conclusions The indications for using ECMO in critically ill patients with AMI combined with CS need to be further refined.VIS score,lactate acid,time from onset to PCI,three-vessel lesions,and left main artery lesions are risk factors for patient death.When using ECMO support for high lactate,high VIS score,and three-vessel lesions,caution should be exercised.Early ECMO support can improve the prognosis of appropriate patients by reducing lactate,reducing the use of vasoactive drugs,and shortening the time from onset to PCI.
