Introduction:Identifying the reciprocal changes would be of significance in predicting the extent of the disease. Thereby high risk and poor outcome among these patients can be predicted. This study is based on the hypothesis that reciprocal ST segment changes have concomitant multivessel stenosis and LV dysfunction.

Objectives:To assess left ventricular dysfunction in patient with andwithout  reciprocal ST Segment changes.

Methods and materials: Patients who are admitted in Father Muller Medical College Hospital with the diagnosis of ST segment elevation acute myocardial infarction.Study population was divided into 2 groups ,Group A: Anterior STEMI and Group B: Inferior STEMI.Each group subdivided into two subgroups according to presence of reciprocal ST segment depression (RSTD): A1 and B1, Absence of RSTD: A2 and B2. 

Results:Among the cases,42.5% with reciprocal changes had severe LV dysfunction, which was statistically significant (p value= 0.03).
