Abstract：Objective To investigate the clinical situations and prognosis of patients with acute anterior myocardial infarction and ST segment elevation(STE) in lead V4R.MethodsRetrospectively select 132 cases of patients with the disease, among which there were 49 cases in V4R-STE group and 83 in nonV4R-STE group. Separately Observe the ranges of STE and increase of myocardial enzymes by routine 12 lead electrocardiogram(ECG) as well as left ventricular ejection fraction and ventricular wall motion by echocardiogram. Cardiovascular events include attacks of congestive heart failure or malignant arrhythmia(such like multifocal ventricular premature beats, ventricular tachycardia and ventricular fibrillation) and the happens of death. In addition, take a close observation on coronary arteriongraphy of patients in the two groups. ResultsBetween the two groups, compare the range of STE on 12 lead ECG and left ventricular ejection fraction and segmental abnormality incidence of ventricular wall motion, which resulted in statistically insignificant differences(P>0.05). In the meantime, for 49 cases in the V4RSTE group, the range of myocardial enzymes as well as the incidence rates of cardiovascular events and multivessel diseases(P<0.01). Conclusion It needs to take 18 lead ECG for patients with acute anterior myocardial infarction with SET in order to evaluate recovery of heart and prognosis more accurately.
