Abstract

High risk groups of inferior STEMI patients are those with heart block, right ventricle infarction (RVI), cardiogenic shock and cardiac arrest.RVI occurs in approximately one third of patients with inferior STEMI, in about one half of those patients, it is of hemodynamic significance. RVI results in a decrease in the right ventricle (RV) compliance and an increase in filling pressures, consequently the RV stroke volume decreases. RV diastolic dysfunction serves as an early quantifiable marker of subclinical RV dysfunction and usually present before apparent systolic dysfunction, RV dilatation or RV hypertrophy. By reviewing the literature there is scant data on Evaluation of RV diastolic function.
AIM OF THE STUDY
Evaluation of the prognostic value of RV diastolic function in patients with RV infarction.
PATIENTS AND METHODS
The study enrolled 60 patients who presented with inferior STEMI and RV infarction and underwent primary PCI at the Alexandria Main University Hospital and National Heart Institute from October 2019 to December 2020. Echocardiography study with analysis of PW doppler velocities (E vel, A vel, DT and E/A) and TDI velocities (e`, a`, E/e`) was done. All enrolled patients had RCA occlusion proximal to RV branch.
