This is because coronary artery stenosis or vasospasm in angina pectoris leads to the decrease of coronary blood flow and the increase of myocardial oxygen consumption will lead to sharp ischemia and hypoxia and the accumulation of too many metabolites in myocardium. it is caused by stimulating the afferent fiber terminals of the autonomic nerve in the heart which is located in the same or adjacent spinal nerve center as the autonomic nerve afferent to the upper abdomen so it is mistakenly felt as abdominal pain Acute myocardial infarctionAcute myocardial infarction especially inferior myocardial infarction occurs because the vagus nerve afferent fiber receptors are almost located on the surface of the inferior wall of the heart. So when myocardial ischemia hypoxia stimulate the vagus nerve causing gastrointestinal flatulence or spasm resulting in abdominal pain. And accompanied by vomiting Diarrhea etc. easy to mistake for cholecystitis gastric perforation
