Once suffering from coronary heart disease, no one dare to take it lightly. However, some patients with coronary heart disease do not have obvious angina, but are accompanied by abdominal pain, neck and back pain and other symptoms that can be easily misdiagnosed. Asymptomatic coronary heart disease usually has no conscious symptoms, but can be suddenly transformed into angina pectoris or myocardial infarction, can also occur sudden death. Therefore, chest tightness, with abdominal pain, neck and back pain and other symptoms of elderly patients, we must find out why. First, abdominal pain back pain is actually myocardial infarction Grandpa Xu 65 years old, a moment of pleasure more than a little wine. At night, feel the pain in the upper abdomen began, the second half of the night, abdominal pain intensified, and accompanied by a feeling of chest tightness, had to wake up the family, send him to the hospital. Initially, at home near the hospital, the doctor according to the treatment program for digestive diseases, grandfather Xu prescribed some gastrointestinal drugs. However, after taking the medication, his condition did not improve, and finally his family took him to a higher level of hospital treatment, only to diagnose Grandpa Xu is myocardial infarction. Relevant statistics show that in the sudden cardiac death, about 1/4 belong to asymptomatic coronary heart disease patients. The cause of sudden death is based on coronary atherosclerosis, coronary artery spasm or thrombus blockage leading to acute myocardial ischemia. Asymptomatic coronary artery disease is also known as insidious coronary artery disease. It has no clinical symptoms, but there are ECG changes of myocardial ischemia. In reality, the patient is not truly asymptomatic, but rather the symptoms associated with coronary artery disease are hidden, ignored, and misinterpreted. For example, ectopic pain, that is, pain in the throat, teeth, neck, upper abdomen, back of the shoulder, left forearm, and even lower extremity areas, this type of pain, although the location of the different parts, but the triggers are often exertion, cold, satiety, agitation, etc., in paroxysms. Another example is the elderly appear after activity chest tightness and breathlessness, shortness of breath, after resting to relieve the symptoms, can not be ruled out care disease attack. Second, asymptomatic coronary heart disease is serious consequences Some patients with myocardial infarction due to lesions lighter or coronary artery collateral circulation to establish a better, or due to the patient’s pain threshold is higher, the patient in the electrocardiogram on the obvious changes, but they do not feel obvious physical discomfort, and even infarction is not obvious, which is clinically known as “asymptomatic coronary heart disease This is clinically known as “asymptomatic coronary heart disease”. Asymptomatic coronary artery disease can be suddenly transformed into angina pectoris or myocardial infarction, can also slowly develop into heart failure, and some patients have sudden death. These patients are not easily detected and cannot take the necessary precautions in time because they usually have no self-conscious symptoms. Because the pain is sometimes located in the upper abdomen, it is easy to be misdiagnosed as gastric perforation or acute pancreatitis. There are also a small number of patients who present with neck and back pain. For this reason, if an elderly person experiences these symptoms and conventional treatment is ineffective, he or she should think of myocardial infarction as the culprit. Special reminder: once the patient is diagnosed with myocardial infarction, the patient should first strictly bedridden, keep quiet, avoid excessive mental stress; sublingual nitroglycerin or nitroglycerin spray inhalation. Immediately contact with the nearby large hospitals, while ready to be transported to the hospital. Transportation must be able to transfer smoothly. The patient should avoid getting up. Transportation on a stretcher when the situation is relatively stable may enable some patients to avoid serious consequences. Early emergency intervention or thrombolysis can restore coronary blood flow in time and improve treatment outcome.
