Causes of Arteriosclerosis

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.

Arteriosclerosis is a disease

Arteriosclerosis is a disease characterized by thickening of the arterial wall and narrowing of the arterial lumen due to plaque formation, leading to various problems. As for whether arteriosclerosis can be prevented and treated, the answer is definitely yes. This can be achieved by maintaining good lifestyle habits. Regular exercise, quitting smoking, and controlling blood pressure and blood sugar with medications under a doctor’s guidance, as well as appropriate use of statin medications, can effectively prevent and treat the onset, progression, and worsening of arteriosclerosis.

The difference between arteriosclerosis and atherosclerosis.

Arteriosclerosis and atherosclerosis are two different concepts. Arteriosclerosis is a type of vascular disease within arteriosclerosis, but atherosclerosis is more commonly significant clinically. Hence, it is customarily referred to simply as arteriosclerosis, generally implying atherosclerosis. The causes of arteriosclerosis are numerous, but they share common characteristics including thickening, hardening, loss of elasticity, and narrowing of the arterial walls. Atherosclerosis is characterized by lesions starting in the innermost layer of the artery, involving local accumulation of lipids, complex carbohydrates, fibrous tissue proliferation, and calcification forming plaques, along with a gradual degeneration of the innermost layer. The lipid accumulation gives the inner layer a yellowish, porridge-like appearance, hence the name atherosclerosis.

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.

Causes of arteriosclerosis

The etiology of arteriosclerosis has not been fully determined, and studies indicate that arteriosclerosis is a multifactorial disease, caused by multiple factors acting at different stages, which are referred to as risk factors. The primary risk factors include the following: First, age and gender. Clinically, it is more common in middle-aged and elderly people over forty years old. After the age of forty-nine, the progression is fast, but early arteriosclerotic changes have also been found in autopsy of some young adults and even children. In recent years, clinical onset age tends to be younger. Compared to men, the incidence rate in women is lower, because estrogen has a protective effect against arteriosclerosis. Therefore, the incidence rate in women increases rapidly after menopause. Age and gender are unchangeable risk factors. Second, abnormal lipid levels, with abnormal lipid metabolism being the most important risk factor for arteriosclerosis. Third, hypertension, as the incidence of arteriosclerosis in patients with hypertension is significantly higher. Sixty to seventy percent of patients with coronary arteriosclerosis have hypertension, and patients with hypertension are three to four times more likely to have arteriosclerosis compared to those with normal blood pressure. Fourth, smoking, as the incidence and mortality rate of coronary arteriosclerosis in smokers are two to six times higher than in non-smokers, and it correlates positively with the number of cigarettes smoked daily. Secondhand smoke is also a risk factor. Fifth, diabetes and glucose intolerance, where not only is the incidence of arteriosclerosis in diabetic patients several times higher than in non-diabetics, but the progression of the disease is also rapid. Sixth, obesity, defined as being more than twenty percent over the standard weight or a BMI greater than twenty-four. Obesity is also a risk factor for arteriosclerosis. Seventh, family history, where a family history of coronary heart disease, diabetes, hypertension, and hyperlipidemia significantly increases the incidence of coronary heart disease. Various theories have been proposed to explain the pathogenesis of coronary arteriosclerosis from different perspectives. These include the lipid infiltration theory, thrombosis theory, and smooth muscle cell clonal theory. In recent years, the endothelial damage response theory has gained more support, suggesting that the disease results from various risk factors ultimately damaging the arterial intima, and the formation of arteriosclerosis lesions is an inflammatory, fibro-proliferative response of the arteries to endothelial damage.
