I should be asking what are the dangers of atherosclerotic plaques. The hazards of atherosclerotic plaques are different according to the different parts of its existence, and the common ones are cerebral thrombosis and cerebral hemorrhage, angina pectoris, heart attack, renal failure, intermittent claudication and so on. 1. Cerebral thrombosis and cerebral hemorrhage: when atherosclerotic plaque occurs in cerebral blood vessel, it may cause cerebral blood vessel stenosis, and the embolus formed after the plaque is dislodged may induce cerebral thrombosis, and the rupture of plaque may also cause cerebral hemorrhage, which will make the patient’s life in danger. 2. Angina pectoris and heart attack: If atherosclerotic plaque occurs in coronary artery, it will cause narrowing of coronary artery, affecting blood supply and oxygen supply to myocardium and inducing angina pectoris. Secondary thrombosis blockage of coronary arteries can also cause heart attack, resulting in myocardial ischemia and necrosis. 3. Renal failure: when renal artery atherosclerosis occurs, renal artery will become narrow, which will lead to insufficient perfusion or even no perfusion of kidneys, and renal ischemia may lead to renal insufficiency or even renal failure. 4. Intermittent claudication: When atherosclerotic plaque occurs in the arteries of the lower limbs, it will lead to insufficient blood supply to the muscles of the lower limbs, making it difficult to walk due to pain, which is called intermittent claudication. If the above discomfort occurs, it is recommended to consult a doctor as soon as possible to avoid delaying the condition.
