Coronary atherosclerosis can cause myocardial ischemia and hypoxia, which may result in symptoms such as discomfort in the precordial area, palpitations or weakness, and chest pain. Coronary atherosclerosis is atherosclerosis of the coronary arteries, which causes narrowing or occlusion of the lumen of the coronary arteries. This leads to ischemia, hypoxia, or necrosis of the heart muscle, which may result in symptoms such as discomfort in the precordial area, palpitations, or fatigue. Chest pain is a typical symptom, which can be triggered by physical activity, emotional excitement, causing sudden pain in the precordial area, colic or squeezing pain, feeling of suffocation, etc. The pain can also radiate to the left shoulder, left arm and other parts of the left arm, and even some patients can also experience chest pain when resting. When suffering from coronary atherosclerosis, it is recommended to be actively treated under the guidance of a doctor.
