High risk factors are: hypertension, diabetes, hyperlipidemia, obesity, physical inactivity, alcohol abuse, smoking, etc. High risk factors greatly increase the risk of stroke. Risk factors greatly increase the risk of stroke. 90% of the risk of stroke (including hemorrhage and ischemia) is attributed to 10 controllable risk factors: 34.6% of strokes are attributed to hypertension! Can atherosclerosis be caused without any risk factors? Atherosclerosis is caused by the growth of plaque in the lining of blood vessels or by calcification and stiffening of the vessel walls, resulting in a decrease in the compliance of the vessels, figuratively called sclerosis. Atherosclerosis can occur without risk factors because as we get older, the blood vessels themselves age, much like an old car tire that has not been replaced for a long time. The mechanism of atherosclerosis is very complex, and what has been found so far is mainly that various risk factors are related to the pathogenesis, but the exact mechanism is not very clear. Therefore, atherosclerosis can occur without risk factors. Can stroke be passed on to the next generation? Genetic factors are an independent risk factor for the development of stroke. People whose relatives (including parents and siblings) have had a stroke are more likely to have a stroke. People with a family history of stroke should be more concerned about their health, but they should not be blindly pessimistic because stroke occurs as a result of several risk factors working together. Genetics is only one factor. Most people can avoid cerebrovascular disease if they maintain a healthy lifestyle, stay away from smoking and alcohol, and actively control hypertension, diabetes, and hyperlipidemia. How does diabetes cause strokes? It leads to atherosclerosis of the cerebral blood vessel wall, which gradually thickens or even calcifies the vessel wall. It impairs the function of endothelial cells in the cerebrovascular wall and accelerates the formation of atherosclerosis. Long-term hyperglycemia, impaired cerebral blood flow autoregulation, and occlusion of small cortical arteries that play an important role in collateral circulation. It directly leads to brain cell damage. It makes the blood in a hypercoagulable and hyperviscous state, which aggravates the cerebral blood circulation disorder. Can heart disease cause a stroke attack? Yes, cardiogenic stroke is a stroke caused by embolism of the cerebral arteries due to heart emboli passing through the circulation. It accounts for about 20% of ischemic strokes and is associated with atrial fibrillation, acute heart attack, intracardiac thrombosis, valvular heart disease and prosthetic heart valves, with a 5% risk of first stroke in untreated atrial fibrillation. Can high blood lipids cause strokes? High blood lipids tend to make the blood thick and sticky and deposit it on the walls of blood vessels, gradually forming small plaques, which are often called atherosclerosis, and these plaques increase in size, gradually blocking the blood vessels and causing blood clots to form, slowing blood flow and, in severe cases, blocking it. This condition occurs in the heart, leading to coronary heart disease, and in the brain, leading to stroke.
