How to diagnose myocardial infarction

Myocardial infarction is a heart disease that harms many middle-aged and elderly men, and the mortality rate of myocardial infarction is very high. Therefore, when symptoms of myocardial infarction appear in the body, you should go to the hospital for diagnosis in time. Myocardial infarction mainly affects the insufficient blood supply around the human heart, causing dysfunction of the normal heart function. The following article introduces some methods for diagnosing myocardial infarction.

When we experience chest pain accompanied by symptoms such as chest tightness, palpitations, heart palpitations, shortness of breath, etc., we must be alert as it may be related to myocardial infarction. Myocardial infarction, also known as myocardial infarction, is caused by occlusion of coronary arteries, interruption of blood flow, and local necrosis of part of the myocardium due to severe and persistent ischemia. Clinically, myocardial infarction is characterized by severe and persistent pain behind the sternum, fever, leukocytosis, accelerated erythrocyte sedimentation rate, increased serum myocardial enzyme activity and progressive electrocardiogram changes, which may lead to arrhythmia, shock or heart failure.

To confirm whether it is myocardial infarction, we cannot rely solely on electrocardiogram diagnosis. This is why the electrocardiogram shows myocardial infarction, but the doctor says it is nothing. But this does not mean that electrocardiogram diagnosis is meaningless. Whether myocardial infarction is diagnosed or not, the following conditions must be met.

1. Electrocardiogram examination: There is a necessity for electrocardiogram examination, which is clinically significant for confirming whether it is myocardial death. Especially in the diagnosis of ST-segment elevation myocardial infarction, the electrocardiogram is often of decisive significance, but not all myocardial infarctions have electrocardiogram changes, and not all myocardial infarction electrocardiogram changes are very typical. This point cannot be ignored, and changes in the electrocardiogram cannot be simply used as the basis for diagnosing myocardial infarction.

2. Changes in myocardial enzymes: Increased myocardial enzymes are of the most important significance in the diagnosis of myocardial infarction. Even with typical electrocardiograms and symptoms, myocardial infarction cannot be diagnosed without myocardial necrosis and increased myocardial enzymes.

3. Symptoms: In some cases, even if there are no changes in the ECG or myocardial enzymes, if there are symptoms of myocardial death, emergency PCI treatment is required as soon as possible to avoid delaying and aggravating the symptoms and causing danger.

4. Coronary artery CT or coronary angiography: These examinations are also important criteria for diagnosing myocardial infarction. To confirm myocardial infarction, these examinations can also be used.

Therefore, when the electrocardiogram is diagnosed as myocardial infarction, do not worry too much. With the improvement of the results of myocardial enzymes, coronary artery examinations, etc., it is possible to rule out myocardial infarction.
