Submaximal ECG stress test is one of noninvasive, practical, and good cost-effective tool that can help finding out residual post AMI risks which are unrecognized at rest, stratifying risks post AMI in order to plan appropriate therapeutic strategies. Objectives: Determining ratio of positive submaximal ECG stress test due to residual myocardial ischemia, ratio of heart failure and arrhythmias at stress test.
