What could be the reason for having heart discomfort for several years without a clear diagnosis, and what should be done?

Generally, if someone has experienced prolonged cardiac discomfort for several years without a clear diagnosis, it may be due to factors such as unhealthy eating habits, high mental stress, myocardial ischemia, heart failure, or coronary atherosclerotic heart disease. If physical discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:

1. Unhealthy eating habits: Regular consumption of high-fat foods such as fried chicken, hamburgers, and lard, or irritating foods like chili peppers, mustard, hot pot, and ice cream, can stimulate the body and increase the burden on the heart, leading to feelings of cardiac discomfort. Adjusting the diet to include light, easily digestible foods such as millet porridge and steamed buns may help alleviate symptoms.

2. High mental stress: Prolonged periods of stress, tension, or anxiety may lead to autonomic nervous system dysfunction, causing symptoms such as chest tightness, shortness of breath, and palpitations. These symptoms can be improved by relaxing the mind and managing emotional well-being.

3. Myocardial ischemia: Myocardial ischemia affects blood circulation in the heart, leading to cardiac dysfunction and symptoms including palpitations, chest tightness, and difficulty breathing. Patients may take medications such as aspirin sustained-release tablets, nicorandil tablets, or atenolol tablets under medical guidance to improve their condition.

4. Heart failure: Heart failure is a cardiac dysfunction caused by excessive cardiac load, myocardial damage, respiratory tract infections, and other factors. It may impair blood circulation in the thoracic cavity, resulting in symptoms such as dyspnea, chest pain, and palpitations. Under a doctor's supervision, patients may use medications such as metoprolol tartrate tablets, bisoprolol fumarate tablets, or ramipril tablets for treatment.

5. Coronary atherosclerotic heart disease: If a patient’s coronary arteries develop lesions with thrombosis or plaques, the arterial walls may thicken, leading to narrowing or blockage of the arteries and causing myocardial hypoxia, which results in cardiac discomfort. This condition is caused by coronary atherosclerotic heart disease. Patients may take medications such as simvastatin dispersible tablets, atorvastatin calcium tablets, or isosorbide nitrate tablets as prescribed by a physician.

In daily life, it is recommended to consume foods rich in protein, vitamins, and minerals, such as eggs, lean meat, tomatoes, and apples, to provide necessary energy and support overall health.
