Be alert to the signs of acute myocardial infarction!

Most patients suffer from acute myocardial infarction. As a patient, you must correctly grasp the treatment and prevention, and treat the symptoms to be more effective. Usually there are many symptoms of acute myocardial infarction. In normal times, you may experience chest tightness and shortness of breath due to emotional excitement. Some people cannot be detected through physical examination alone, and local detection of myocardial infarction is required.

Early symptoms of myocardial infarction

1. Acute myocardial infarction is a common cardiovascular emergency. With the improvement of people's living standards, its incidence rate is increasing year by year, but the age of onset is decreasing year by year. The progress of medical science and the rapid development of the integration of traditional Chinese and Western medicine have gradually reduced the mortality rate of this disease. For patients and their families, the key to reducing mortality is early detection and early and appropriate treatment.

2. In the early stages of a typical acute myocardial infarction, there will be sudden and unbearable pain in the center of the chest, which will last for a long time and is usually accompanied by obvious sweating. Some patients may also experience signs of heart and kidney yang deficiency, such as cold hands and feet. In severe cases, shock, coma, and even sudden death may occur rapidly. For some patients this is no longer truly “early”.

3. Patients with acute myocardial infarction do not experience the above-mentioned typical severe precordial pain in the early stage of the disease. They only experience mild pain or even no precordial pain at all, and manifest as chest tightness, shortness of breath, etc. Some people are only discovered during a physical examination or during treatment for other illnesses.

Typical symptoms of myocardial infarction

Although the typical pain site of acute myocardial infarction is in the precordial area, the pain site in some patients is extremely atypical and may manifest as toothache, stomachache, nausea, vomiting, back pain or arm pain. For this reason, we must be vigilant about sudden and unexplained pain in the above-mentioned areas.

Another point that needs special attention is that angina pectoris will develop gradually, and sudden worsening of "angina pectoris" may be a manifestation of myocardial infarction. Severe stenosis of the coronary arteries can cause angina of varying natures. The pain of stable angina is not severe and the attacks are infrequent, and it can be quickly relieved by taking nitroglycerin sublingually. When frequent and difficult-to-relieve angina pectoris occurs suddenly in the recent period and measures such as rest and nitroglycerin are ineffective, unstable angina should be highly suspected. The latter is most likely to suddenly transform into acute myocardial infarction due to thrombosis in a short period of time. The clinical manifestation at this time is still precordial pain, but the disease has undergone fundamental changes. The pain often suddenly worsens and becomes unbearable for the patient, often accompanied by profuse sweating, cold hands and feet, etc. At this time, the pain in the precordial area has changed from angina pectoris to the pain of myocardial infarction.
