How to identify the abnormal myocardial infarction atypical performance?

Not typical of myocardial infarction, performance varied, and often cause misdiagnosis and missed diagnosis, people should be vigilant. Atypical myocardial infarction mainly in the following categories:
Painless myocardial infarction was particularly prevalent in elderly patients, often without clear after onset of chest pain performance, but only for the performance was pale, he was weak, poor appetite or nausea, vomiting, low blood pressure, etc.. This is because older pain unresponsive, or broken out because of illness, a sudden massive myocardial necrosis, and can not be caused by the pain. To this end, for elderly patients, once the performance of this unusual thing (not necessarily initiate a private prosecution with a heart condition), or ECG should be done.
Stomach to the performance of myocardial infarction also more common in the elderly, the private prosecution, abdominal discomfort, and vague, complaining of nausea and vomiting, to the acid, such as heartburn, they asked in detail about, the patient usually the lack of "stomach problems" history of stomach problems and there is no clear relationship between the consumption of , but with the exertion or emotional changes, such patients should pay attention to the possibility of myocardial infarction.
A flustered, shortness of breath, expectoration performance of myocardial infarction after myocardial infarction can cause varying degrees of myocardial necrosis and affect the heart of systolic function, and even cause heart failure. Therefore, encountered coronary heart disease, hypertensive patients sudden chest tightness, cough, vomit white sputum, not flat, should consider the possibility of acute myocardial infarction.
Suddenly collapsed to the performance of myocardial infarction or convulsion This is a more serious type of myocardial infarction. As myocardial damage after cardiac electrical activity disorder, caused arrhythmia vulnerable, such as outdoor tachycardia, atrial fibrillation, the patient will occur syncope or convulsion, encountered such a situation should immediately be crowded in vitro heart pressure until the patient regained consciousness immediately after sending a hospital for treatment. Other special performance of myocardial infarction clinical practice, there are still some patients with acute myocardial infarction extremely subtle signs and symptoms, such as performance of throat pain. Pain, neck and back pain, diarrhea, heart disease appears to be irrelevant, but middle-aged and older patients, if repeated or sudden increases in the above symptoms, they should think of the possibility of acute myocardial infarction.
