ABSTRACT Introduction: This article studies the echocardiographic images of patients and observes the changes in diastolic cardiac function after exercise. Objective: This article tries to find the relationship between cardiac images during exercise and the diagnosis of myocardial ischemia. Methods: Samples of people with equal fitness for the same exercise area were selected with specific equipment to measure the sample ventricular strain curve before and after 5 minutes to exercise with a load. The diastolic strain index (SDI) ratio before and after exercise assesses the relationship between myocardial ischemia and exercise load. Results: The test results showed no significant difference in the range of motion of the cardiac atrioventricular annulus both before and after subjects were subjected to intense exertion exercise. A significant change in slope was noted in the ECG data curve about the exercise index, in addition to a reduction in the diastolic period. Conclusion: When the exercise load increases, it can easily cause changes in the ventricular wall. This can make local myocardial dysfunction more prone.
