Arteriosclerosis, the most common and important type of arteriosclerosis, is characterized by thickening and hardening of the arterial walls, loss of elasticity, and narrowing of the lumen. The causes are currently considered to be related to several factors, including age and gender, with older males being more prone. Patients with abnormal blood lipids, hypertension, smokers, those with diabetes or impaired glucose tolerance, obese patients, and those with a family history are all more likely to develop arteriosclerosis. Due to the incomplete certainty of the causes, its prevention and control are also managed through multiple factors.

What medicine to take for arteriosclerosis?

Drug therapy is an important component of the treatment for atherosclerosis and mainly includes the following types. The first is to regulate blood sugar and lipids, keeping them under control to slow down the process of atherosclerosis. The second involves taking antiplatelet medications to prevent the formation of blood clots, especially since some plaques, particularly soft plaques, are prone to rupture. For some patients who have already formed blood clots, thrombolytic therapy might be considered, but this is not typically necessary for all patients. Additionally, because high blood pressure can accelerate the progression of atherosclerosis, some patients also need to take antihypertensive drugs. For patients with narrowed blood vessels and severe symptoms, such as angina, vasodilators, including nitrates, might be used. Therefore, the treatment choices may vary depending on the severity of the condition, and the modes of drug therapy differ. (Note: Specific medications should be taken under the guidance of a doctor.)

How to check for arteriosclerosis?

Arteriosclerosis is a relatively common disease in our daily life. After being diagnosed with arteriosclerosis, the following tests should be considered: Firstly, blood tests, such as lipid panels, are necessary to determine the levels of blood lipids. Based on the results, medication might be required for treatment. Secondly, arterial Doppler ultrasound is useful as it can effectively detect the presence and severity of arteriosclerosis. Thirdly, arterial angiography is recommended when there is a strong suspicion of arterial narrowing due to arteriosclerosis, leading to coronary heart disease or other conditions. This test helps in determining the severity of the arteriosclerosis and in deciding the treatment plan.

The earliest lesions of arteriosclerosis

The earliest lesion of atherosclerosis is the formation of lipid spots and streaks. The so-called lipid spots are small yellow dots that appear on the arterial intima. Under pathological observation, these are small areas of macrophages containing lipid droplets, forming a cluster of foam cells. As this small yellow dot develops, it gradually turns into a yellow streak made up of layers of macrophages containing lipids. The intima also comprises smooth muscle cells and lipids, as well as an infiltration of T cells, resembling a yellow streak on the intima.

Treatment of Arteriosclerosis

The treatment of arteriosclerosis includes general preventative measures, pharmacological treatment, interventional procedures, and surgical operations. General precautions involve a balanced diet, with some patients needing to lose weight, increasing the intake of fruits and vegetables, quitting smoking and limiting alcohol consumption, and adopting a low-fat diet. Additionally, it is advised that patients engage in appropriate physical labor and sports activities, while also maintaining an optimistic and calm mindset. Pharmacological treatment is quite specialized, mainly including lipid-lowering and antiplatelet therapies. Then, there are cases with clear symptoms, such as renal artery stenosis or coronary artery narrowing, where interventional treatments can be considered. For those unsuitable for interventional procedures, surgical treatments, such as bypass surgery, might be considered.

The difference between arteriosclerosis and atherosclerosis

Arteriosclerosis is the most common and most important among a group of vascular diseases called arteriosclerosis. The common characteristics of various arteriosclerosis include thickening, hardening, loss of elasticity, and narrowing of the arterial walls. The characteristic of arteriosclerosis is that the affected arterial lesions start from the intima, with various lesions coexisting, including local accumulation of papyraceous and complex carbohydrates, proliferation of fibrous tissue, and formation of plaques due to calcification, along with gradual degradation of the arterial media. Secondary lesions include intraplaque hemorrhage, plaque rupture, and local thrombosis formation. Modern cellular and molecular biology techniques show that arteriosclerotic lesions are characterized by migration of macrophages, proliferation of smooth muscle cells, and abundant formation of fibrous, collagen, elastic fibers, and proteoglycans as connective tissue matrices, as well as intra- and extracellular lipid accumulation. Because the lipid accumulation in the intima appears yellow and mushy, it is called arteriosclerosis. Although arteriosclerosis is only one type of arteriosclerosis, it is commonly referred to simply as arteriosclerosis due to its frequent occurrence and significant clinical relevance.
