Myocardial ischemia can sometimes cause pain in the stomach, especially in inferior myocardial ischemia, which can lead to pain in the stomach. When we have an acute inferior myocardial infarction, it will no longer cause stomach pain, but may also cause nausea and vomiting. This is not the time to blindly consider gastrointestinal disorders, such as ulcers or gastritis, and other situations, but to insist on an electrocardiogram to clarify the diagnosis. There are many patients with acute inferior wall myocardial infarction who are mistaken for gastrointestinal diseases and delay the best time for resuscitation, leading to complications and even the possibility of death. At this time, if it is clear that it is an inferior wall myocardial infarction after an ECG, the patient should be given immediate recanalization treatment, such as intravenous thrombolysis or emergency coronary intervention.
