摘要
Objective:To seek the relation between clinical presentation(Braunwaldclassification)or electrocardiogram(ECG)and angiographic morphology inpatients with unstable angma(UA),and to determine which clitoral markerscould reliably predict unstable lesions and cardiac eventsMethods:120 hospdalized patients with a clinical diagnosis of UA and anabonrmal angiograms(≥50% diameter stenosis)were selected The lesionmorphology included sunple lesion,complex lesion and inracoronarythrombus(ICT)In-hospital events included acute myocardialinfarction,cardiac death and prompt revasculan-zation Logistic regressionwas used to evaluate the ability of clinical markers to predict unstable lesionsand cardiac events.Results:There were more complex lesion in class Ⅲ group(61%,or 20 of33)than in class 1 group(30%,or 13 of 43,P【0.05)and more ICT in class Ⅲgroup(18%.or 6 of 33)than in class Ⅱ group(2%,or 1 of 44,P【0.05)Thetare of cardiac events was higher m class Ⅲ patients(58%,or 19 of 33)thanin class 1 patients(19%,or 8 of 43,P=0.01)or in class Ⅱ patients(25%,or Ⅱof 44,P【0.01)Logistic regrassion analysis demonstrated that an abnormalST segment of ECG or Braunwald class Ⅲ were highly predictive of thepresence of complex lesion morphology(P【0.01,OR 4.9,P【001,OR3.3,respectively)An abnormal ECG was the single predictive clintcalindicator of triple coronary disease(P【0.01.OR 3.9)and cardiacevents(P【0.001,OR 4.8).Conclusion:Complex lesion can be best identified by the clinical featureof recent onset refractory angina at rest and abnormal ECG Patients withabnormal ST segment represents a high rate of triple coronary disease anda high risk of cardiac events.
