Acute Inferior Myocardial Infarction With Right Ventricular Infarction In A Retrospective Analysis

ObjectiveRight ventricle infarction is not rare in acute myocardial infarction. Because Right ventricle infarction is usually accompanied by inferior infarction and backwall infarction, it is hard to recognize and diagnosis. The risk factors, clinical symptoms and treatments of patients who suffered acute inferior infarction accompanied by right ventricle infarction in single-institutiont is retrospectively analysed.MethodsThe risk factors, clinical symptoms, coronary artery changes, treatments, prognosis and prognosis of patients who suffered acute inferior infarction accompanied by right ventricle infarction in 2009-2010 are retrospectively analysed.Results5 patients who suffered acute inferior infarction accompanied by right ventricle infarction are retrospectively analysed. In clinical symptoms,1 patient showed syncope first,1 patient showed cardiogenic shock first,3 patients showed chest pain first.1 patient had the trilogy of right ventricle infarction. In ECG,4 patients V3R-V6R showed QS type or QR type; 2 patients showed V3RST elevated;4 patients not only showed ST elevated inⅡ,Ⅲ,aVF, but also showed the elevated extent of STⅢ/STⅡ＞1; 2 patients showed pathological Q wave inⅡ,Ⅲ,aVF; 1 paitents hadⅡ°AVB. In serum myocardial zymogram, the mean value of the peak value of the CK-MB was 92.4U/L, the mean value of the peak value of the troponin I was 92.4U/L, these values were all in accordance with the serum myocardial zymogram changes in acute myocardial infarction. In UCG,1 patient showed abnormal motion of the left ventricle, inferior, backwall, postero-septal, mild pulmonary hypertension. In coronary angiography,4 patients showed right coronary artery lesions,3 patients showed right coronary artery entirely shut,1 patientsConclusionsAcute inferior myocardial infarction complicated by right ventricular myocardial infarction usually occurs in the right coronary artery culprit vessel near the middle, and severe stenosis, the left anterior descending artery and circumflex artery disease is not caused by right ventricular infarction.
