What is coronary heart disease, and what are its symptoms?

Coronary heart disease generally refers to coronary atherosclerotic heart disease, a condition in which the coronary arteries develop atherosclerosis, thromboembolism, or vasospasm, leading to arterial narrowing or blockage that impairs blood flow and results in myocardial ischemia. It commonly causes symptoms such as chest pain, radiating pain, and palpitations. A detailed analysis is as follows:

1. Chest Pain

Chest pain is the most characteristic symptom of coronary atherosclerotic heart disease. Patients typically experience a sensation of pressure, tightness, heaviness, or pain behind the sternum or in the precordial area. The duration of pain varies; it may occur at rest or during physical activity.

2. Radiating Pain

The area of chest pain is usually about the size of a palm, but it can also radiate to other regions, causing pain in the left shoulder, inner left arm extending to the ring and little fingers, or even to the neck and jaw.

3. Palpitations

The disease can cause palpitations, particularly after excessive physical exertion or intense exercise, with symptoms becoming more severe. Persistent palpitations may lead to profuse sweating, restlessness, a sense of impending doom, and in severe cases, arrhythmias.

In addition, some patients may also experience fatigue, weakness, and recurrent fever. It is recommended to actively treat the condition under a doctor's guidance to stabilize the disease progression.
