In mild coronary atherosclerosis, there are usually no symptoms. When it develops to a moderate to severe degree, symptoms such as angina pectoris and chest tightness may occur. When it develops to a severe degree, symptoms of acute myocardial infarction will appear.
1. Mild atherosclerosis: Generally speaking, mild atherosclerosis has no symptoms.
2. Moderate and severe atherosclerosis: As the disease continues to develop, when it reaches moderate and severe atherosclerosis, it will lead to narrowing of the lumen of the blood vessels, and symptoms such as angina pectoris and chest tightness in the precordial area, which tends to last for a few minutes to 30 minutes, may appear during emotional excitement and exertion.
3. Severe atherosclerosis: If severe atherosclerosis develops, blood clots will be easily formed, leading to complete occlusion of the lumen, and acute myocardial infarction will occur, which is manifested as severe crushing chest pain in the precordial region, which is intense and often lasts for more than 30 minutes without any relief, and is accompanied by dizziness, profuse sweating, nausea, vomiting and other symptoms.
