1, dyspnea
This is the earliest and most common symptom of left heart failure. It is mainly caused by acute or chronic lung blood stasis and decreased vital capacity. Lighter people have difficulty breathing only when they are doing heavy physical labor, and disappear soon after rest, so it is called labor-induced dyspnea. This is because labor promotes the increase of blood volume, and when the right heart function is normal, it further promotes the aggravation of lung blood stasis. With the progress of the disease, mild physical activity means difficulty breathing, and serious people will feel difficulty breathing at rest, so that they are forced to take a semi-lying position or a sitting position. This situation is called sitting breathing (forced sitting breathing). Because sitting can make blood be affected by gravity and accumulate in low hanging parts such as lower limbs and abdomen, the blood volume returning to the heart is less than that when lying down, and the congestion in the lungs is reduced. At the same time, when sitting, the diaphragm decreases, the vital capacity increases, and the dyspnea is alleviated.
Paroxysmal nocturnal dyspnea is the manifestation of left heart failure. Patients often wake up in deep sleep, feel suffocated, forced to sit up, often cough, and have serious breathing difficulties. After sitting up for several minutes, the symptoms disappeared. In severe cases, cyanosis, cold sweat and wheezing can be heard in the lungs, which is called cardiogenic asthma. In severe cases, it may develop into pulmonary edema, cough up a lot of foamy blood sputum, and the lungs are covered with moist rales, and the blood pressure may drop or even go into shock.
2. Cough and hemoptysis
This is a common symptom of left heart failure. Due to congestion of alveolar and bronchial mucosa, it is often accompanied by dyspnea, blood foam or blood sputum.
3. Others
There may be fatigue, insomnia, palpitations, etc. Severe brain hypoxia can cause Chen's breathing, drowsiness, dizziness, loss of consciousness, convulsions and so on.
4. Symbols
In addition to the original signs of heart disease, the apical region may have diastolic galloping rhythm, the second heart sound in the auscultation region of pulmonary valve is hyperactive, and moist rales can be heard at the bottom of both lungs. In severe cases, the lungs are full of moist rales accompanied by wheezing, and alternating pulsation often occurs.
5. How to maintain your heart?
1, nourishing the heart depends on the season.
Pay attention to the season when nourishing the heart. It is easy to sweat in summer. Chinese medicine believes that sweat is the fluid of the heart, and excessive sweating will damage the heart yang. Therefore, we should have more rest in summer and do some less strenuous exercise, such as playing Tai Ji Chuan, brisk walking and jogging. Exercise time is generally controlled at about 40 minutes, and you can sweat slightly.
2. Nutritionists should not do strenuous exercise in the morning.
You should do "quiet exercise" in the morning. The world's healthiest schedule shows that it is not suitable for strenuous exercise in the morning, so you can walk to work. The clinical study of the Medical College of the University of Massachusetts in the United States shows that the cold rate of people who walk to work every day is 25% lower than that of people who take buses.
Don't change walking to running. Researchers in brunell, England, found that people who run in the morning are more likely to catch a cold; On the other hand, Japanese experts found that running in the morning will increase the risk of thrombosis by 6%.
3, nourishing the heart should not be anxious or overeating.
Belgian researchers believe that cocaine ranks first among the causes of heart disease, followed by overeating, ecstasy and rage. If you take cocaine, the incidence of heart disease will increase by 2300%; If you overeat, the incidence of heart disease will increase by 700%; Ecstasy and rage increase the risk of heart disease by five times.
Like caffeine, there is overeating. American researchers have found that the probability of heart attack within two hours of overeating is four times that of ordinary people, and it is 10 times within one hour. Keep your mouth shut, keep good intentions and cooperate with your work and rest, and you can keep your heart strong.
4. Choose a good time to nourish your heart
According to the World's Healthiest Work Schedule, you can take a hot bath before 1 1 at night and then go to sleep. This timetable coincides with the theory of Chinese medicine. After getting up, wake up from sleep and drink a glass of water. This is the suggestion of the Sleep Research Center of Loughborough University. Drinking water is to make up for the lack of water for 8 hours of sleep. Researchers at the University of California found that women who drink five glasses of water a day (250 ml each) are 465,438+0% less likely to have heart disease than women who drink only two glasses of water a day. Meridian sleep from 1 1 to 1 at noon, and from 1 1 at night to 1 in the morning are all important periods for nourishing the heart.
5. Keep your heart in a good mood.
Studies have shown that laughter can relax vascular endothelium and increase blood flow; And once you laugh, this effect will last at least 45 minutes. If people are often depressed and depressed, over time, the heart function is not as good as that of their peers; Every day, the nerves are tense and the heart burden will be great; In addition, quarreling will also have a bad effect on the heart.
6, nourishing the heart should only eat seven points full.
An experiment in the United States shows that mice reduce their food intake by 30% every day, and the result is actually extended by 30%. Life. What's even more incredible is that thin people's hearts may be younger than fat people 10 to 15 years old. Other relevant data show that the insulin level of people who limit calorie intake is significantly higher than that of ordinary people, and the signs of DNA damage are also reduced. Scientists believe that controlling food can reduce the damage of hyperglycemia to tissues, reduce the occurrence of inflammation and reduce free radicals.
The food in the diet should be diversified, the hunger should be moderate, seven or eight points full, coarse grains should be eaten with flour and rice, and three meals should be arranged reasonably. Eat more fish, nuts, cereals, fruits and vegetables, and eat less animal fat. In addition to eating bitter food, you can also eat sour food, such as kiwi fruit, oranges, and spicy food, such as garlic, onion, ginger, pepper, etc., which can promote blood vessel oxidation. In addition, we should pay attention to less salt, preferably no more than 6 grams per day, limit sweets and eat less oil, preferably no more than 25 grams per day.
7, nourishing the heart, suffering more, clearing the heart.
Decompression of the heart can start with eating. Chinese medicine believes that the best ingredient for the heart is bitter. Huangdi Neijing records: "Bitter to the heart, bitter to the bone, bone disease is not bitter." Chinese medicine believes that many diseases are caused by fire, and bitterness is the best fire extinguisher. This statement has also been verified by western medicine. Food is bitter because of its bitterness. The most basic function of bitterness is diuresis and lowering blood sugar, and diuresis is to reduce the burden on the heart.
8, nourishing the heart should be properly supplemented with vitamins.
Pay attention to eating foods rich in vitamin B6. If vitamin B6 is deficient, it will inhibit amino acid metabolism and increase serum cholesterol, which will lead to the formation and deterioration of heart diseases.
Eat more vegetables, fruits, beans, sesame oil and peanut oil rich in vitamin E and C. Vitamin E can improve the symptoms of heart disease caused by hypertension and prevent the formation of oxidized low density lipoprotein (LDL) that damages coronary arteries. Vitamin C can remove lipids from intima and tissues of arterial blood vessels, avoid lipid precipitation and sclerosis, and is beneficial to the repair of arterial injury.
Carotene has potential anti-aging and antioxidant effects in blood, which can prevent the formation of oxidized low-density lipoprotein and cholesterol, protect arterial blood vessels and reduce the occurrence of cardiovascular and cerebrovascular diseases, so you can eat more foods containing carotene.
