Atherosclerosis has no fixed time from plaque formation. Atherosclerosis is the phenomenon of decreased elasticity and hardening of the arterial wall, usually manifested by lipid accumulation, fibrous tissue proliferation, and calcium deposits in the affected arteries and the formation of plaques. Atherosclerosis is a chronic process that may be related to factors such as dyslipidemia, elevated blood pressure, diabetes, genetics, smoking, and obesity. Each person’s physical condition is not exactly the same, the occurrence of atherosclerosis sooner or later and the time of plaque formation is different, so atherosclerosis from the time of plaque formation is also variable. Atherosclerosis generally has no obvious symptoms in its early stages. However, as the plaque increases in size and the affected artery narrows, symptoms such as dizziness, headache, chest tightness, abdominal pain, and high blood pressure may occur. Therefore, if you suspect atherosclerosis and plaque formation, you can go to the hospital for further examination of ultrasound, arterial CT angiography and other items to check the severity of the condition.
