Whether sudden death can occur due to vague heart pains needs to be judged according to the cause of occurrence, and cannot be generalized. Generally, the following causes of vague heart pains do not cause sudden death: 1, caused by excessive emotional stress or cardiovascular neurosis, often accompanied by insomnia and dreaminess, irritability and other symptoms; 2, caused by gastric ulcer, chronic gastritis and other digestive tract diseases, often accompanied by epigastric fullness, hiccups, acid reflux, diarrhea and other symptoms; 3, caused by intercostal neuritis, pneumothorax, pleurisy and other chest wall diseases. Usually only coronary artery disease, angina pectoris and other heart diseases that cause long-term myocardial ischemia may lead to sudden death. The heart often has crush-like, stuffy or suffocation-like pain, accompanied by chest tightness, profuse sweating and other symptoms, which can be controlled by drugs such as compound salvia drops under the tongue under the guidance of a doctor. If it cannot be relieved, seek medical attention early. It is recommended to go to cardiovascular medicine department for electrocardiogram, cardiac ultrasound, coronary angiography and other examinations to clarify the cause and treat the symptoms. At the same time, it is important to ensure a relaxed mood, reasonable rest, and strengthen physical exercise.
