Introduction: Early recognition of acute right ventricular myocardial infarction (RVMI) is very crucial for the initiation of treatment to avoid
complications. Objective: The objective of this study is to assess the predictors of complications in patients with acute inferior and RVMI. Patients
and Methods: This prospective, single‑center study included 100 patients with acute inferior and RVMI presented within 6 h of symptoms onset.
All patients received streptokinase as thrombolytic therapy. The patients had undergone conventional two‑dimensional echocardiography to
assess LVEF, RVEF, RVFAC, and tricuspid annular plane systolic excursion (TAPSE), tissue Doppler to assess s`, e`, a` waves and myocardial
performance index (MPI), and speckle tracking echocardiography to assess RV global longitudinal strain. All echocardiographic parameters
were done within the first 12 h of admission and 2 months later. Results: Of 100 patients with acute RVMI; 27 patients had complications, the
most common complication was atrioventricular block followed by cardiogenic shock. Mortality occurred in only one patient. On comparing the
complicated and noncomplicated groups on admission, we revealed that; as regarding the clinical data, the female gender, presence of diabetes,
lower systolic and diastolic blood pressure, and lower pulse were independent risk factors for occurrence of complications in RVMI with
P < 0.029, 0.009, 0.004, 0.009, and 0.0001, respectively. Of the echo‑cardiographic parameters on admission, dilated RV, lateral S, MPI, TAPSE,
and speckle were independent predictors for the occurrence of complications in patients with RVI with P < 0.005,
