Once you have coronary heart disease, no one dares to take it lightly. However, some patients with coronary heart disease do not have obvious angina, but have symptoms that are easily misdiagnosed, such as abdominal pain, neck and back pain. Asymptomatic coronary heart disease usually has no conscious symptoms, but it can suddenly turn into angina pectoris or myocardial infarction, and sudden death can also occur. Therefore, elderly patients with symptoms such as chest tightness with abdominal pain and neck and back pain should always find out the cause. Abdominal pain and back pain is actually myocardial infarction Grandpa Xu is 65 years old and drank a little more wine in a moment of joy. At night, he felt pain in his upper abdomen, and in the second half of the night, the abdominal pain increased and was accompanied by a feeling of tightness in the chest, so he had to wake up his family and send him to the hospital. Initially, at the hospital near home, the doctor prescribed some gastrointestinal medication for Grandpa Xu according to the treatment plan for gastrointestinal diseases. However, after taking the medicine, his condition did not improve, and finally his family took him to a higher level hospital, where he was diagnosed with a myocardial infarction. Statistics show that among sudden cardiac deaths, about 1/4 belong to patients with asymptomatic coronary heart disease. The cause of sudden death is acute myocardial ischemia due to spasm or thrombotic blockage of coronary arteries on the basis of coronary atherosclerosis. Asymptomatic coronary heart disease is also known as occult coronary heart disease. It has no clinical symptoms, but there is an electrocardiogram change of myocardial ischemia. In fact, the patient is not truly asymptomatic, but the symptoms associated with coronary artery disease are concealed, ignored and misinterpreted. For example, ectopic pain, i.e. pain in the throat, teeth, neck, upper abdomen, back of shoulder, left forearm, or even lower extremity, which varies in location but is often triggered by exertion, cold, satiety, agitation, etc. and is paroxysmal. Another example is that the symptoms of chest tightness and shortness of breath after activity and relief after rest in the elderly cannot exclude the onset of care disease. Asymptomatic coronary heart disease has serious consequences Some patients with myocardial infarction have obvious changes on the electrocardiogram due to mild lesions or better establishment of the collateral circulation of the coronary artery, or due to the patient’s high pain threshold, but they do not feel obvious physical discomfort, and they do not feel obvious even after an infarction, which is called “asymptomatic coronary heart disease” in clinical practice. This is called “asymptomatic coronary artery disease”. Asymptomatic coronary heart disease can suddenly turn into angina pectoris or myocardial infarction, or slowly develop into heart failure, or some patients suddenly die suddenly. These patients are not easily detected and cannot take the necessary precautions in time because they usually have no conscious symptoms. Since the pain is sometimes located in the upper abdomen, it can be easily misdiagnosed as gastric perforation or acute pancreatitis. A small number of patients also present with neck and back pain. For this reason, if such symptoms occur in the elderly and conventional treatment is ineffective, one should think of myocardial infarction as the culprit. Special reminder: Once a patient is diagnosed with myocardial infarction, the patient should first be strictly bedridden, keep quiet and avoid excessive mental tension; take nitroglycerin under the tongue or nitroglycerin spray inhalation. Immediately contact a nearby major hospital, while making preparations for transport to the hospital. Transportation must be capable of smooth transfer. Patients should avoid getting up and be transported on a stretcher when their condition is relatively stable, which may allow some patients to avoid serious consequences. Early emergency intervention or embolization can restore coronary blood flow and improve treatment outcome.
