ABSTRACT
It's important to identify patient with dominant right ventricular infarction with inferior wall MI in which right ventricular dysfunction is primarily responsible for development of hypotension and cardiogenic shock Jacob, et al., 2000.Aim to assess tissue Doppler imaging is a useful method for the detection of the right ventricular myocardial infarction in patients with acute inferior wall myocardial infarction. Thirty patients, nine females and twenty-one males, admitted to [CCU] at Al-Hussein University Hospital between December 2009 and July 2010, classified into 2 groups, group A 15 without RVI and group B 15 with RVI plus Control group C Ten healthy individuals ;following scheme. History, risk factors, Clinical examination, 12 leads ECG ,Cardiac enzyme and Echocardiography was performed within 48 hours after the MI. As the following. Left ventricular ,Right ventricular study,Pulsed Tissue Doppler parameters show statistically significant difference between groups in JVP, Blood pressure ,cardiac enzymes, Right ventricular ejection fraction ,tricuspid annular motion ,Tricuspid regurgitation, Myocardial systolic velocity, Myocardial early diastolic velocity, Myocardial late diastolic velocity ,Isometric contraction time Jsometric relaxation time, Ejection time, myocardial performance index. The right ventricular MPI increases in patients with RVMI when accompanied by acute inferior wall MI .So RVMI could be diagnosed and predicted correctlyby the use of these Tissue Doppler imaging which are easily obtained
