血管斑块（动脉粥样硬化斑块）的形成是一个复杂的病理过程，主要由多种危险因素共同作用导致。首先，高血脂是关键诱因之一，尤其是低密度脂蛋白胆固醇（LDL-C）水平升高，容易在血管内皮沉积，引发炎症反应并逐渐形成斑块。其次，高血压会损伤血管内皮，使脂质更容易渗入血管壁，加速斑块形成。糖尿病或血糖控制不佳也会损害血管内皮功能，并促进氧化应激和炎症，从而加剧动脉粥样硬化。此外，吸烟会直接损伤血管内膜，增加血液黏稠度，同时降低高密度脂蛋白（“好”胆固醇）水平，进一步推动斑块发展。缺乏运动、肥胖、不健康饮食（如高盐、高脂、高糖）以及长期精神压力也被证实与斑块形成密切相关。遗传因素也不容忽视，有家族史的人群往往更早出现动脉粥样硬化。因此，预防血管斑块的关键在于综合管理上述风险因素：保持健康生活方式、定期体检、控制“三高”（高血压、高血脂、高血糖），戒烟限酒，并在医生指导下必要时使用药物干预。
The formation of arterial plaque—also known as atherosclerotic plaque—is a complex pathological process driven by multiple risk factors. Elevated blood lipids, particularly high levels of low-density lipoprotein cholesterol (LDL-C), are a primary contributor, as they tend to accumulate in the inner lining of arteries, triggering inflammation and gradually forming plaques. Hypertension damages the endothelium (the inner vessel wall), making it easier for lipids to infiltrate and accelerate plaque buildup. Poorly controlled diabetes impairs endothelial function and promotes oxidative stress and chronic inflammation, worsening atherosclerosis. Smoking directly injures the vascular endothelium, increases blood viscosity, and lowers levels of high-density lipoprotein (HDL, the ‘good’ cholesterol), further fueling plaque development. Additional contributors include physical inactivity, obesity, unhealthy diets (high in salt, saturated fats, and sugar), and chronic psychological stress. Genetic predisposition also plays a role—individuals with a family history of cardiovascular disease often develop atherosclerosis earlier. Therefore, preventing plaque formation hinges on comprehensive risk factor management: adopting a healthy lifestyle, undergoing regular health screenings, controlling the ‘three highs’ (hypertension, hyperlipidemia, and hyperglycemia), quitting smoking, limiting alcohol intake, and, when necessary, using medications under medical supervision.
