Symptoms before myocardial infarction:

1. Before a myocardial infarction, angina pectoris usually occurs frequently, and the pain is more severe and lasts longer than before. Previously, it could be relieved by a short rest, but before a myocardial infarction, it can occur even with slight activity or even rest. Even taking nitroglycerin has little effect, and the patient is often irritable and sweats a lot.

2. Before a myocardial infarction occurs, the patient may suddenly experience a series of symptoms of left heart failure, including unexplained coughing, shortness of breath, and other breathing difficulties, or even coughing up foamy sputum.

3. Some patients may experience cold symptoms or gastrointestinal symptoms such as dizziness, nausea, vomiting, diarrhea, etc. before the onset of myocardial infarction, accompanied by symptoms such as lack of energy, fatigue, drowsiness, and irritability.

4. Some patients will experience symptoms such as palpitations and shortness of breath before a myocardial infarction, and their pulse will often be irregular and repeated, accompanied by a drop in blood pressure.

5. Some patients reported experiencing chest tightness and angina pectoris before a myocardial infarction, and felt palpitations and shortness of breath with the slightest activity.

6. Some patients do not have typical symptoms of precordial pain before the onset of myocardial infarction, but instead experience toothache, left shoulder swelling and pain, and stomach discomfort.

About 2/3 of patients with acute myocardial infarction have prodromal symptoms a few days before the onset of the disease, the most common of which is angina pectoris, followed by upper abdominal pain, chest tightness and shortness of breath. Half of the patients had new-onset angina pectoris, and the other half had existing angina pectoris, with sudden frequent attacks or aggravated pain and prolonged duration, with no obvious cause and poor efficacy of nitroglycerin. The angina attacks were accompanied by nausea, vomiting, sweating, tachycardia, acute heart failure, and severe arrhythmias.
