Are ST-segment changes on an electrocardiogram indicative of myocardial ischemia?
Disease description:
Recently, I have occasionally experienced weakness in my heart’s pumping ability. An electrocardiogram (ECG) revealed ST-segment changes. Could you please clarify whether ST-segment changes on an ECG indicate myocardial ischemia?

ST-segment changes on an electrocardiogram (ECG) generally suggest possible myocardial ischemia (inadequate blood supply to the heart muscle). However, a definitive diagnosis cannot rely solely on ST-segment alterations; it must be made comprehensively by integrating the patient’s clinical symptoms with findings from additional diagnostic tests—such as echocardiography and cardiac enzyme panels. Early, targeted treatment is essential once myocardial ischemia is confirmed, to prevent complications including angina pectoris or even myocardial infarction.
