Main symptoms of coronary heart disease

Coronary heart disease, also known as coronary atherosclerotic heart disease, is a common cardiovascular disease. The main reason is insufficient blood supply from the coronary arteries, leading to myocardial ischemia, hypoxia or necrosis. The symptoms of coronary heart disease are diverse. There may be no obvious symptoms in the early stage, but as the disease progresses, symptoms will gradually appear. This article will introduce in detail the main symptoms of coronary heart disease and their clinical significance.

1. Chest pain: Chest pain is the most common symptom of coronary heart disease, usually manifesting as chest pressure, dull pain or burning sensation. The pain is mostly in the precordium area and can radiate to the left shoulder, left arm, mandible, etc. The onset of chest pain is related to physical activity, emotional excitement and other factors, and can be relieved by rest or the use of nitroglycerin. Chest pain may be a manifestation of myocardial ischemia and requires attention.

2. Dyspnea: Patients with coronary heart disease may have difficulty breathing when performing physical activities. This is due to the weakened pumping function of the heart, resulting in insufficient oxygen supply to tissues and organs throughout the body. In addition, heart failure may also cause difficulty breathing.

3. Palpitations: Palpitations refer to abnormal heartbeat sensations, such as too fast, too slow or irregular heartbeats. Patients with coronary heart disease may experience palpitations due to arrhythmias caused by myocardial ischemia. Palpitations may increase the burden on the heart and affect the quality of life.

4. Fatigue: Patients with coronary heart disease may experience fatigue and fatigue when performing physical activities. This is due to the weakened pumping function of the heart, resulting in insufficient oxygen supply to tissues and organs throughout the body. Fatigue may affect a patient’s ability to perform daily life and work.

5. Nausea and vomiting: Patients with coronary heart disease may experience symptoms such as nausea and vomiting during myocardial ischemia. This is due to gastrointestinal dysfunction caused by myocardial ischemia. Nausea and vomiting may worsen the patient’s discomfort.

6. Sweating: Patients with coronary heart disease may sweat during physical activity, which is caused by sympathetic nerve excitement. Sweating may increase the burden on the heart and affect the quality of life.

7. Dizziness and syncope: Patients with coronary heart disease may experience symptoms such as dizziness and syncope when myocardial ischemia occurs. This is due to the weakened pumping function of the heart, resulting in insufficient oxygen supply to tissues and organs throughout the body. Dizziness and syncope may be life-threatening.
