Clinical manifestations of myocardial infarction

Myocardial infarction is caused by the aggravation of diseases such as coronary heart disease and angina pectoris. In general, myocardial infarction is easy to distinguish from other diseases. Myocardial infarction often manifests itself with symptoms such as chest tightness and nausea. If this condition is not treated in time, once the condition worsens, it may lead to more dangerous symptoms such as inability to breathe and pale complexion. Therefore, treatment should be given in the early stages of the disease.

Myocardial infarction is a relatively dangerous disease. The incidence rate is higher in the elderly and the mortality rate also has a clear increasing trend. Therefore, it is important to effectively curb the progression of the disease. However, this requires that we have a preliminary understanding of myocardial infarction in order to prescribe the right medicine.

Typical clinical manifestations of acute myocardial infarction:

a) The first symptom is pain. Its location and nature are similar to angina pectoris, that is, sudden severe pain behind the sternum or in front of the heart, radiating to the left shoulder, arm or other parts, but the pain is significantly aggravated and lasts for a long time, and cannot be relieved by nitric anhydride oil. Patients often sweat profusely, feel irritable, fearful, or have a sense of impending death.

b) Severe pain is often accompanied by frequent nausea, vomiting, intestinal flatulence and upper abdominal pain. In severe cases, hiccups may occur.

c) Fever, tachycardia, arrhythmia, etc. may appear one to two days after the pain occurs, and may be accompanied by fatigue, dizziness, syncope and other symptoms.

d) Pain often causes a drop in blood pressure, and in severe cases, shock may occur.

e) Some patients may experience acute left heart failure, dyspnea, cough, cyanosis, irritability, and in severe cases, pulmonary edema and coughing up pink frothy sputum.

Atypical clinical manifestations of acute myocardial infarction:

a) There are no pain symptoms or the pain is not severe, so it is not taken seriously. This is usually seen in the elderly and people with diabetes.

b) The location of pain is atypical. For example, some patients experience pain in the upper abdomen, which can be easily mistaken for gastric perforation or acute pancreatitis.

c) Some patients present with shock or acute heart failure as soon as the disease occurs, without obvious pain symptoms.

The above is a detailed introduction to the clinical manifestations of myocardial infarction from two aspects. I believe that everyone now has a deeper understanding of myocardial infarction. In this way, we can make a preliminary judgment on myocardial infarction in the early stages and avoid seeking medical treatment in a hurry. I hope the above explanation can be helpful to all patients.
