Prognostic value of right ventricular diastolic dysfunction in patients with inferior ST elevated myocardial infarction

Abstract Background Right ventricle infarction (RVI) is predominantly a complication of inferior wall myocardial infarction; it occurs in approximately one third these patients. dysfunction patients with STEMI and RV was under assessed. Nevertheless, studies which targeted assessment by echocardiography, did not evaluate diastolic dysfunction. Purpose In this study, we aimed to its prognostic value RVI. Methods Sixty infarction, who underwent primary PCI were enrolled the study. Presence pre-existing clinical conditions that might affect function, excluded. Echocardiography performed within twenty-four hours following PCI, assess systolic functions special focus on tricuspid inflow velocities (E velocity, A velocity E/A ratio) pulsed wave (PW) doppler annular tissue index (TDI) (e', a' E/e' ratio). Clinical features MACE, including cardiogenic shock, arrhythmia, stroke, reinfarction death analyzed all our 3 months follow up period. Results The average age study population 51.58±10.11 years, 10% females. Five developed MACE (death, shock pulmonary oedema, anterior recurrent STEMI, arrhythmia stroke), whom four occurred hospital first 48 hours. Patients had high filling pressures, as them >6. E' ≤6 cm/s associated increased 25% e' compared 2.3% >6 P 0.015. Conclusions Because PW varies respiration, volume status other conditions, TDI are essential when evaluating has Inferior infarction.
