Angina pectoris and myocardial infarction are two serious cardiovascular diseases that pose a great threat to human health. Angina pectoris is a temporary chest pain caused by insufficient blood supply to the coronary arteries, while myocardial infarction is due to ischemic necrosis of myocardial tissue due to blockage of the coronary arteries. The symptoms of the two diseases are similar, but the severity and methods are different. At critical moments, correct identification of angina pectoris and myocardial infarction is essential for timely treatment and improved survival rates.
1. Identification of angina.
1.Pain location: The pain of angina pectoris is mainly located in the posterior part of the sternum and can radiate to the left shoulder, inner left arm, neck, jaw, upper abdomen, etc.
2.Nature of pain: The pain of angina pectoris is usually a sensation of pressure, tightness, or burning, and can sometimes manifest as a pinprick or knife-like pain.
3.Pain level: Angina pectoris is less painful and the patient is usually able to tolerate it without experiencing extreme distress or shock.
4.Painful episodes: Angina attacks are usually associated with physical activity or emotional agitation, and the pain is relieved with rest or nitroglycerin.
5.Duration: Angina pectoris is a pain that lasts for a short period of time, usually a few minutes and rarely more than half an hour.
2. Identification of myocardial infarction.
1.Location of pain: The pain site of myocardial infarction is similar to angina, mainly located in the posterior part of the sternum, and can radiate to the left shoulder, inside of the left arm, etc.
2.Nature of pain: Myocardial infarction is severe and presents with a severe, persistent sensation of pressure or tightness, sometimes accompanied by a sensation of suffocation.
3.Pain level: The pain level of myocardial infarction is severe, and patients may experience symptoms such as extreme pain, sweating, paleness, and shortness of breath.
4.Onset of pain: The onset of pain in a myocardial infarction is similar to that of angina pectoris, but may persist after rest or nitroglycerin.
5.Duration: The pain of a myocardial infarction lasts for a long time, usually more than half an hour, and can even reach several hours or longer.
3. How to distinguish angina pectoris from myocardial infarction.
1.Pain level: Angina pectoris is less painful, whereas myocardial infarction is more painful.
2.Painful episodes: Painful episodes of angina are associated with physical activity or emotional agitation, while painful episodes of myocardial infarction may persist after rest or nitroglycerin use.
3.Duration: Angina pectoris is painful for a shorter duration, usually a few minutes, while myocardial infarction is painful for a longer duration, usually more than half an hour.
4.Accompanying symptoms: Patients with myocardial infarction may be accompanied by nausea, vomiting, abdominal distention, sweating, hypotension, shock and other symptoms.
5.ECG changes: ECG of myocardial infarction shows characteristic changes of myocardial ischemia, injury, and necrosis, whereas ECG changes are subtle for angina.
Fourth, emergency treatment.
As soon as you suspect that you or someone else is experiencing symptoms of angina or myocardial infarction, you should take the following measures immediately:
1.Immediately stop ongoing activities and find a safe place to sit.
2.Call 120 or local emergency services** as soon as possible to inform your doctor of your symptoms and location.
3.Stay calm, breathe as deeply as possible, and avoid nervousness and anxiety.
4.If you carry nitroglycerin with you, take it sublingually and tell your doctor that it is used.
5.Wait for the ambulance to arrive and do not drive or walk to the hospital on your own.
Angina pectoris and myocardial infarction are two serious cardiovascular diseases, and timely recognition and treatment are crucial. Master the symptoms and characteristics of angina pectoris and myocardial infarction, and be vigilant, which can save lives at critical moments. I hope that everyone can pay attention to their heart health and prevent the occurrence of cardiovascular diseases. If in doubt, do not hesitate to consult a medical professional.
