How long can one live with arteriosclerosis?
Arteriosclerosis has a certain impact on survival and longevity, but it is not an absolute determinant. People with mild arteriosclerosis have fewer sudden incidents of cerebral infarction and myocardial infarction, thus they may have a longer survival period. However, if arteriosclerosis leads to myocardial infarction or cerebral infarction, it will also affect their lifespan, but there is no absolute conclusion.
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.
How is arteriosclerosis treated?
To treat arteriosclerosis, we differentiate treatments based on the severity of the condition. For early-stage patients, we emphasize the control of lipids, blood pressure, and blood sugar to potentially slow the progression of arteriosclerosis. For patients who have already suffered damage to target organs, such as cerebral infarction, myocardial infarction, renal artery stenosis, or mesenteric artery stenosis, treatment might significantly rely on medication, and could possibly require the use of stents or even surgical bypass procedures. For the general population, we emphasize primary prevention, which includes a reasonable diet, appropriate exercise, and a balanced mental state to effectively prevent the disease.
Can arteriosclerosis be cured?
Atherosclerosis can only slow down its further progression and prevent the further occurrence of conditions such as coronary heart disease, cerebral infarction, and lower limb arterial occlusion. This is because it is influenced by many factors, including both modifiable and non-modifiable risk factors. For example, modifiable factors include abnormal blood lipids, hypertension, diabetes, smoking, and overweight obesity, which we can change. However, there are also non-modifiable factors such as age, genetics, and environmental factors. As age increases, the incidence of atherosclerosis significantly rises. Its pathological changes generally begin in childhood or adolescence, with symptoms becoming more apparent as age progresses.
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.
What tea to drink for arteriosclerosis?
Patients with arteriosclerosis can drink various types of tea, including green tea, black tea, chrysanthemum tea, goji berry tea, and ginseng tea. These teas can be consumed to increase blood flow, renew knowledge, enhance circulation, cleanse the blood vessels, and alleviate arteriosclerosis. However, one should not rely solely on drinking tea to treat arteriosclerosis. It is also necessary to use certain medications and adjust dietary structures, adopting a low-fat, low-salt, low-sugar diet, avoiding animal liver and fatty meats, reducing the intake of fried foods, and abstaining from high-cholesterol foods such as cream, fish roe, and shrimp.
What medicine is used for arteriosclerosis?
Commonly, some medications used to adjust blood lipids are employed, primarily to lower low-density lipoprotein levels, and some are also aimed at achieving target levels for triglycerides. These include statins, fibrates, and niacin. For some patients, antiplatelet drugs might be necessary to prevent acute thrombus formation and avoid acute incidents. For those who have already formed a thrombus, thrombolytic drugs can be used within a certain time window for some patients. For patients with coronary artery accumulation leading to angina, vasodilators, receptor blockers, or calcium channel antagonists might be used to alleviate the symptoms of angina.
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.)
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.
What tests are used for arteriosclerosis?
If arteriosclerosis is in the early stages, we need to understand the situation with lipids and blood sugar, so lipid and blood glucose tests should be done. Later on, when some atheromatous plaques appear, examinations such as color Doppler ultrasound and cardiac echocardiography can be done to assess blood flow and the degree of narrowing in the vessels. For some severe narrowings, consider conducting a CTA, MRI, or angiography, which can non-invasively understand the lesions of arteriosclerosis. For some patients, if there is a need for interventional treatment, invasive, selective arterial angiography can be performed to understand the condition of the lesions. Therefore, different tests can be chosen at different stages.
