In acute myocardial infarction, patients mostly show sudden and continuous pain in the precordial and retrosternal regions, accompanied by profuse sweating, pallor and a sense of near death, but this does not represent all heart attack patients, knowing that there are extremely many variants of the disease, and there are three kinds of conditions that may cause this: 1. Some heart attack patients do not have typical symptoms, such as chest pain, chest tightness and shortness of breath, but in the abdomen, throat, teeth and joints Pain appears, so patients think it is a minor illness and do not go to the hospital in time for examination. 2. Some patients are born with higher pain valves and better established collateral circulation, so that even if there is complete vascular occlusion, there may still be no symptoms, such as asymptomatic myocardial ischemia. Since such patients usually have difficulty in perceiving the symptoms, they will not find the condition, so for these patients they should develop the habit of regular medical checkups and reading more emergency science, and if the first signs are found, they should be treated in time. 3. Some patients who also have diabetes mellitus may not feel pain due to frequent combined neuropathy and weakened pain perception. Do not ignore the atypical symptoms of heart attack: 1. inexplicable headache 2. syncope without any symptoms 3. irrelevant stomach pain 4. toothache for which no reason can be found 5. heart attack behind heavy sweating 6. inexplicable anxiety The cause of heart attack occurs, in addition to the conventional plaque stenosis, there is another possibility: Speaking of cervical spine disease, I believe no one is unfamiliar with it, a decade or so ago it was considered to be “middle-aged disease”, but as the Internet becomes more and more widespread and increasingly powerful, cervical spine problems are common and have become a common disease of modern people, and the age boundary is becoming less and less obvious, although its affected population is large and does not sound insignificant, but in fact the danger is very great, and the causative factor for some patients with myocardial infarction It is it. As the saying goes: “Running water does not rot, the household pivot does not decay”. Once the cervical spine has problems, there is the possibility of compression of the surrounding nerve tissue, which will lead to the gradual spasm of its innervated blood vessels in the long run, and the consequence is that the blood cannot flow smoothly, and the water in the blood is slowly consumed, making the blood gradually thicken, and some of the metabolites and toxins in it will slowly coagulate and form thrombus. It is well known that problems occur where blood clots are blocked: the blood vessels in the brain are blocked by blood clots before they are cerebral thrombosis, thrombus blockage in the cardiovascular this is known as coronary heart disease, and myocardial infarction is the clinical manifestation when it is completely occluded. Many people do not think of cervical spine disease, but the consequences are unbearable for many people, so I suggest that all patients with cardiovascular disease can have their spine examined, and there may be unexpected surprises, because this part of the patient is different from other patients with cardiovascular disease, and there is the possibility of recovery.
