The number of years to live with atherosclerotic plaque in both lower extremities is closely related to its degree and needs to be analyzed on a case-by-case basis. If the patient only has atherosclerotic plaques in the lower extremities, and there is no serious narrowing of the arteries and no effect on blood flow, it usually has no effect on life expectancy, and generally does not require special treatment, but only good intervention to prevent its further enlargement and dislodgement. However, if intervention is not actively carried out and allowed to continue to develop, it can gradually lead to narrowing of the vascular lumen and even secondary thrombosis, which can cause limb necrosis and risk of amputation, and muscle lysis leading to myoglobinemia blocking the renal tubules, which can seriously cause multi-organ failure and a certain risk of sudden death. Patients need to pay attention to a light diet in life, avoid long-term smoking, alcohol abuse, staying up late and other factors that accelerate the progress of atherosclerotic plaque, you can moderate physical exercise, and take statin and antiplatelet drugs to stabilize the plaque if necessary.
