Presumably many people have seen a variety of news about sudden death, usually look very healthy adults, suddenly appeared myocardial infarction, heart failure in a short period of time, myocardial necrosis, and thus shock, in the absence of timely rescue, or even within a few hours, the patient will die, clinical sudden cardiac infarction is also known as sudden cardiac death.
According to relevant data surveys, 544,000 people die of myocardial infarction every year in China. On average, every minute, one person dies suddenly. However, the myocardial infarction itself is not absolutely equal to death, if the patient can go to the hospital for interventional treatment at the first time after the onset of the disease, in the case of myocardial damage is not serious, the patient's prognosis is better and the quality of life is higher.
If you want to find myocardial infarction at the first time, you must first understand the symptoms of myocardial infarction. In clinical view, when a myocardial infarction occurs, the most typical symptoms are the following:
1. Pain
According to the data available in clinical practice, pain is the first symptom of myocardial infarction, and its pain location, nature and angina are the same. That is, the patient will have a tightening and squeezing pain in the anterior cardiac area and behind the sternum.
However, unlike coronary heart disease angina, myocardial infarction angina tends to appear in a quiet state, during sleep, and the patient's pain level is more serious, the pain spread is widespread, it will last for hours, or even for several days or so, even if the patient can not be relieved after a long period of rest, containing nitroglycerin, the patient will even have a sense of near death;
2, Systemic symptoms
Affected by myocardial necrosis, in addition to pain, patients will also have fever symptoms, which generally appear about 24-48 hours after the onset of pain, and the severity is mainly related to the scope of infarction.
Usually, the patient's body temperature is generally around 38 ° C, and rarely exceeds 39 ° C. At the same time as the body temperature rises, patients are often accompanied by symptoms such as hypercardia, increased white blood cells, and accelerated erythrocyte sedimentation rate;
3. Gastrointestinal abnormalities
In mainland China, about 30% of patients do not have typical angina at the beginning of the disease, but have symptoms similar to acute gastroenteritis, such as short-term epigastric distention, nausea and vomiting, diarrhea and so on. Some patients also have symptoms such as hiccups and flatulence.
This is the case because the patient has problems such as vagus nerve necrosis, myocardial stimulation, decreased cardiac output, insufficient perfusion of surrounding tissues, and then gastrointestinal cramps;
4. Arrhythmia
At the same time as the appearance of angina, patients are often accompanied by symptoms of arrhythmia, which is manifested by increased heartbeat, shortness of breath, palpitations, fear and so on.
In mainland china, more than 75% to 90% of patients with myocardial infarction will have typical arrhythmias within 1-2 weeks after onset, especially within 24 hours, and abnormal diffuse changes may be present during ECG examination.
In addition to the above four typical symptoms, patients with myocardial infarction may also be accompanied by hypotension, shock, heart failure and other manifestations during the onset of the disease. As mentioned above, the more timely the myocardial infarction is rescued, the better the prognosis of the patient.
Therefore, in the clinical view, as long as the patient suddenly has angina, the duration is too long, and there is no relief after taking the drug, it should be the first time to seek medical treatment for relevant examination and treatment, so as not to miss the best rescue time.
