How long does it take for aspirin to be effective in preventing cardiovascular and cerebrovascular diseases?

Modern medical research has found that the occurrence of coronary heart disease and cerebral thrombosis is mainly caused by atherosclerosis, thrombosis, and vasospasm caused by the viscous aggregation of blood and vascular endothelial dysfunction. These reasons cause heart disease. and blood supply to the brain is reduced or interrupted. Vascular endothelial dysfunction is the initiating factor and central link in the occurrence of coronary heart disease and cerebral thrombosis, and is the more important cause of cardiovascular and cerebrovascular diseases. Therefore, the treatment and prevention of cardiovascular and cerebrovascular diseases must not only target the viscosity and cohesion of blood, but also The purpose is to block the pathological link of endothelial dysfunction. At present, Western medicine for clinical treatment of cardiovascular and cerebrovascular diseases requires a combination of β-blockers, lipid-lowering anticoagulants, medium- and long-acting vasodilators, and other drugs, which is called "cocktail" therapy. Because these drugs are targeted at a certain link in the occurrence of cardiovascular and cerebrovascular diseases, their effects are relatively single. A comprehensive treatment requires the use of multiple drugs. At the end of the 20th century, Tongluo therapy has made significant progress in the prevention and treatment of vascular lesions. Tongxinluo capsule, a representative drug guided by the theory of collateral disease, can not only lower lipids, anticoagulate, and reduce blood viscosity to treat blood lesions, but also improve blood vessels. The dual functions of endothelial function and treatment of vascular lesions can be used to prevent cardiovascular and cerebrovascular diseases. The powerful unblocking effect of Tongxinluo can also resist arteriosclerosis, relieve vasospasm, ablate and stabilize vulnerable thrombotic plaques in blood vessels, thereby effectively treating coronary heart disease and cerebral thrombosis. Long-term use can be used for patients with cardiovascular and cerebrovascular diseases. It can effectively prevent recurrence, and has multi-target and multi-angle treatment and prevention effects, acting as a "cocktail" therapy.

Epidemiology survey shows: low temperature is a risk factor for cardiovascular and cerebrovascular diseases!
Why is cold climate a predisposing factor for cardiovascular and cerebrovascular diseases?
Winter is the season when ① heart disease and ② hypertensive disease are prone to worsening. It is also the season when ③ cerebrovascular disease and ④ acute myocardial infarction are most likely to occur. In cold weather when the daily minimum temperature is below 0°C, the number of cardiovascular and cerebrovascular diseases increases significantly. Mortality rates also increased significantly. Meteorological medicine research results show that 77% of patients with myocardial infarction and 55% of patients with other types of coronary heart disease are very sensitive to climate change, especially sudden drops in temperature, and the incidence of myocardial infarction has increased significantly. Winter is the season with the highest incidence of myocardial infarction in my country, especially when the first strong cold air invades or there is a cold peak passing through, the incidence of cardiovascular and cerebrovascular diseases increases dramatically!
Because ① when the body is in a low temperature state, peripheral blood vessels will constrict, resulting in an increase in vascular resistance and blood pressure, and an increase in cardiac and biliary load, ② increasing the chance of cerebral hemorrhage and myocardial infarction. Also due to shivering due to cold, the body consumes energy to generate heat. ③ The heart must perform greater functions, increasing the chance of myocardial infarction. In addition, due to reduced perspiration in winter, drinking less water makes the elderly feel thirsty. Poor, ④ insufficient water intake, increased blood viscosity. ⑤Vascular resistance and blood pressure increase, and thrombus is easy to form, increasing the chance of cerebral infarction and myocardial infarction. In addition, ⑥ you are prone to respiratory problems in winter, such as upper respiratory tract infections, bronchitis, pneumonia, and asthma, which will aggravate existing cardiovascular diseases.
Note: 00C is a weather warning for cardiovascular and cerebrovascular diseases! To prevent cardiovascular and cerebrovascular diseases, experts recommend 5 health care measures in winter:
1. Cold protection and health care
To avoid the stimulation of severe cold, when the cold wave hits and the temperature drops suddenly, add clothes in time. Keeping warm can prevent blood vessels from contracting and raising blood pressure due to cold, avoid increasing the burden on the heart, and prevent respiratory infections. Change clothes and take a shower in winter to avoid low indoor temperatures. Clothes, shoes and hats should be soft and warm. Patients with rheumatic heart disease should not only keep the room warm, but also need air circulation in the room to prevent influenza. Patients with coronary heart disease should not stay in a closed room for too long. If the air conditioner is turned on for heating in the room, the temperature should not be too high. Because the room is too closed and the temperature is too high, there will be a lack of oxygen in the room, which can easily induce coronary heart disease.
2. Diet and health care
① Eat more foods that are high in calories and rich in nutrients, such as lean meat, chicken, fish, dairy and soy products.
②Eat less greasy food, avoid tobacco and alcohol, and generally eat low-salt, low-fat, and low-cholesterol meals.
③Eating fresh vegetables regularly is also good for lowering and stabilizing blood pressure, such as celery, spinach, tomatoes, radish, garlic, fresh bamboo shoots, etc.
④ Among seafood, kelp, seaweed, jellyfish, and algae are good.
⑤ Various vegetables can be skillfully combined to cook dishes, which not only have curative effect, but also are delicious: such as braised bamboo shoots, stir-fried lean pork shreds with celery, candied tomatoes, sweet and sour jellyfish, sweet and sour radish shreds, chrysanthemum brain eggs Soup, dried seaweed and bamboo shoot soup, etc. may be eaten regularly.
⑥ Hypertensive patients who are accompanied by dizziness, cheeks that are often congested and red, and local numbness should reduce their intake of animal protein and replace part of their diet with soy products rich in plant protein.
⑦ Hypertensive patients with cardiovascular and cerebrovascular diseases can often eat black fungus, white fungus, etc. in order to prevent blood clots and relieve symptoms of cerebral arteriosclerosis.

For those with high blood lipids and cholesterol, it is best to use vegetable oil instead of animal fat for cooking dishes, especially corn oil, sunflower oil, and peanut oil.
⑧Those with habitual constipation should often eat bananas, persimmons, watermelons, cantaloupe, water chestnuts, honey, bee milk, corn flour and other foods to facilitate bowel movement.
3. Sports and health care
Insist on physical exercise to improve cold tolerance. You can participate in some cultural and sports activities within your ability, such as walking outdoors, doing Tai Chi, doing Qigong, etc. Spending 10 minutes outdoors in the sun can lower your blood pressure by 6 mmHg. Ultraviolet irradiation can cause the body to produce a nutrient - vitamin D3. The interaction between vitamin D3 and calcium can control arterial blood pressure. To improve cardiovascular function, endurance exercise is best. Such as jogging, swimming, cycling, etc. The appropriate frequency of exercise is 3-5 times a week, ranging from 20-60 minutes each time, and the intensity of exercise increases from small to large. In addition, just a few minutes of smoking every day can strengthen the body and prevent diseases. For example, ① before getting up, rub your hands continuously, including the palms and backs of hands; ② after getting up, you can stretch your legs and stretch your limbs; ③ when brushing your teeth, you can massage the muscles of your mouth.
4. Emotional health
Control your emotions appropriately and beware of excessive fatigue. Extreme anger or nervousness can induce a stroke! Patients with hypertension should maintain an optimistic and happy mood and avoid: ① ecstasy, ② rage, ③ depression, ④ sadness, ⑤ fear and ⑥ fright.
5. Medication and Health Care
Adhere to regular medication to keep blood pressure stable. Hypertensive patients should not stop taking antihypertensive drugs at will, especially when taking clonidine, propranolol, methyldopa, and reserpine antihypertensive drugs. According to reports, if the drug is stopped suddenly, about 5% of patients will experience a sharp rebound in blood pressure within about 40 hours. Therefore, patients with high blood pressure should insist on taking a maintenance dose for a long time under the guidance of a doctor to keep their blood pressure at a more ideal level. In addition, patients with hypertension should appropriately increase the dosage of antihypertensive drugs during the cold season. Generally, the dosage of antihypertensive drugs should be increased by about one-third in winter.
6． Physical health
Regular physical examination to prevent and treat complications. In winter, you are prone to influenza, rhinitis, pharyngitis, tonsillitis, tracheitis, etc. You should pay attention to prevention and active treatment, and measure your blood pressure frequently. If conditions permit, you should also regularly conduct blood lipids, blood sugar, electrocardiogram, and cerebral blood flow chart. During the examination, abnormalities such as dizziness, difficulty speaking, and numbness on one side of the limbs were found, and they were dealt with promptly.
7. Daily health care
In daily life, pay attention to 6 points: ① When you wake up, do not get up immediately. You should move your body in the bedding and ask your family to warm the room. ② Wash your face and brush your teeth with warm water. ③Wear warm clothes when going to the toilet. ④When going out, wear gloves, hats, scarves, coats, etc., and keep warm. ⑤While waiting for the car, you can do small movements such as standing still. ⑥ Before taking a bath, let the bathroom be filled with hot air and wait until the temperature of the bathroom rises before taking a bath.
