Why is high blood pressure more likely to cause heart failure? Why?

Hypertension is the main cause of heart failure, usually when the patient has excessive heart pressure load, the heart muscle will change its own structure to meet the needs of heart pumping, once the patient's cardiometabolic function is decompensated, heart failure will occur, so hypertension is one of the main causes of heart failure. If the patient has high blood pressure, and belongs to stage 3 hypertension or above, it is necessary to take antihypertensive drugs regularly and throughout the whole process to avoid heart failure, once the patient has chest tightness, shortness of breath, palpitations, accompanied by dyspnea, unable to breathe flat, orthopnea at night, and even coughing up pink foamy sputum, it is highly considered that there is acute heart failure.

Cardiovascular and cerebrovascular diseases are the main complications of hypertension. When a patient has high blood pressure, the blood vessels will gradually spasm and thin due to various factors. Usually, when patients with high blood pressure have excessive cardiac stress, heart failure occurs once the patient's cardiometabolic function is decompensated

Causes of heart failure caused by high blood pressure include hypertensive heart disease and coronary atherosclerotic heart disease. If hypertension persists for a long time, it will cause compensatory hypertrophy of the heart ventricular wall, causing the diastolic function of the heart to be affected, and decompensated thinning will gradually occur with prolongation. Ventricular enlargement, decreased systolic function, and heart failure occur.

Why does a normal blood pressure suddenly develop into heart failure? 1. Lack of attention to hypertension More than 9 percent of essential hypertension belongs to the slow progressive type, the course of the disease develops slowly, and only small blood vessels spasm and constriction occur in the early stage, which causes a temporary increase in blood pressure.

Is high blood pressure combined with heart failure serious? Hypertension is a very common condition in daily life, but some people not only have high blood pressure but also heart failure, for this situation many people want to know whether it is serious, let me share whether hypertension combined with heart failure is serious, let's find out together.

Is high blood pressure combined with heart failure serious?

In severe hypertension, cardiac ejection will encounter strong resistance, decreased cardiac output, myocardial ischemia, hypoxia, left ventricular myocardial hypertrophy, and over time, left ventricular dilation, left ventricular systolic and diastolic dysfunction will occur, until heart failure worsens. Heart failure is a severe stage and final outcome of hypertensive heart disease, 90% of cases'People with heart failure have high blood pressure before it occurs. Generally speaking, hypertension combined with heart failure is more serious, and it needs to be controlled with drugs at ordinary times, and it is easy to cause death if you do not pay attention to control.

Does lowering high blood pressure have an effect on heart failure

Studies have shown that for every 20 10 mmHg increase in blood pressure, the risk of cardiovascular death doubles. Lowering blood pressure** is effective in reducing cardiovascular events, with heart failure reduced by 50% for every 10 12 5 6 mmHg blood pressure lowered.

The results of the HYVET study in the elderly population over 80 years of age showed that controlling blood pressure below 150 90 mmHg significantly reduced various risk events, and the central force failure was reduced by up to 64%.

Dietary prevention of hypertension

1. Food is not too salty: limit salt.

Healthy adults should not consume more than 6 grams of salt per day, including the amount of salt consumed through condiments such as soy sauce, pickles, and monosodium glutamate.

2. Food is not too sweet: limit sugar.

It is best not to eat or eat less oil cakes, fritters, fried cakes, cream cakes, chocolates, milk ice cream, etc., and it is recommended that staple foods should be thick and thin, such as corn, millet, beans, buckwheat, potatoes, etc.

3. Food is not too greasy: limit fat

Limit the intake of livestock meat (especially fatty meat), animal fats and fats (such as lard), cream pastries and other foods in your daily life. No more than 250 grams of fresh milk or yogurt per day. Meat is controlled at 75 grams per day to slow down the cavity, mainly lean meat, such as pigs, cattle, sheep, chickens, ducks and other poultry meat.

4. The food is not too bitter: limit alcohol consumption.

Wine also belongs to the "spicy" food, for people who are addicted to alcohol, experts recommend that men drink no more than 30 grams of alcohol per day, women should reduce the amount by half, and pregnant women do not drink Younaliang wine. It is not advisable to drink highly strong liquor.

5. Food is not too bitter: overeating can cause loss of appetite.

Bitter foods are mainly bitter wheat greens, celery, mustard greens, bitter gourd, coffee, etc. Bitterness can clear heat, the climate in Guangzhou is hot, and it is good to eat some bitter vegetables appropriately, which can clear hepatitis and heart fire. However, the bitter taste is cold after all, and excessive food can damage the spleen and stomach, resulting in loss of appetite, abdominal pain and diarrhea, etc., affecting the digestion and absorption of food.

Long-term hypertension can cause left ventricular pressure overload due to increased ejection impedance, resulting in a decrease in left ventricular pumping function, so that the blood flowing from the pulmonary circulation to the left heart can not fully penetrate the aorta, and the amount of blood remaining in the left heart increases, resulting in myocardial contractile dysfunction At the same time as the cardiac output decreases, pulmonary congestion and even hemorrhage can occur, that is, heart failure

The pathogenesis of heart failure due to long-term hypertension mainly involves myocardial hypertrophy due to stress overload. Excessive myocardial hypertrophy puts it in an unbalanced state of growth, which can be decompensated to decompensated. The distribution density of myocardial sympathetic nerves decreased, and the content of myocardial norepinephrine decreased; The number of myocardial mitochondria increased insufficiently, and the oxidative phosphorylation level of myocardial mitochondria decreased. insufficient increase in the number of myocardial capillaries, poor microcirculatory perfusion; decreased cardiac myosin ATPase activity; Abnormal extracellular Ca2+ influx and sarcoplasmic reticulum Ca2+ release.

The most fatal is myocardial infarction or cerebral hemorrhage, when the blood pressure is very high, it can lead to cerebral hemorrhage and a large amount of cerebral hemorrhage, which can directly threaten life.

Because patients with high blood pressure are prone to elevated blood pressure, causing emergencies such as cerebral hemorrhage and cerebral thrombosis, patients with heart failure are prone to cardiac arrest and organ failure, resulting in death.

When we sat in the streets and chatted with others, some said that Uncle Zhang had high blood pressure and blood pressure 200, and some said that the middle-aged taxi driver also had high blood pressure, and he fainted while driving a taxi that time, and hurriedly called 120 before he was rescued. When I went to the hospital, there was a long queue at the entrance of the cardiovascular and cerebrovascular department, like a giant dragon, which also shows that cardiovascular and cerebrovascular diseases caused by high blood pressure have become one of the most common diseases.

People with heart failure are prone to new sudden death

High blood pressure can be treated with traditional Chinese medicine.

In hypertension, due to the high pressure of arterial blood vessels, the heart is prevented from pumping blood, and the heart is overwhelmed and stiff due to long-term high-load work, which eventually leads to the obstruction of pulmonary venous blood entering the heart and the formation of pulmonary congestion. When the myocardium is hypertrophied, the oxygen demand increases, and the blood ** is relatively insufficient, which often leads to heart failure attacks.

It can be seen that hypertension is closely related to heart failure (especially left-sided heart failure), and is one of the main diseases that impair the diastolic and systolic function of the heart. The clinical features of heart failure due to hypertension are as follows:

Due to abnormal left ventricular diastolic function, pulmonary congestion can occur, mainly manifested as:

1) Fatigue, wheezing, palpitations, cough, hemoptysis and other symptoms; 2) Shortness of breath when lying down, which gets better when sitting up;

3) The amount of activity is not large, but there is difficulty breathing, and in severe cases, the patient can wake up in his sleep.

Left heart failure often involves decreased right ventricular function, resulting in total heart failure, which is mainly manifested as:

1) Cyanosis.

2) significant jugular venous distention;

3) Pain in the right upper quadrant with hepatomegaly;

4) Swelling of both lower limbs, and in severe cases, swelling of the whole body may occur;

5) oliguria, which is more likely to occur in the decompensated stage of heart failure;

6) Cerebrovascular diseases often occur in middle-aged and elderly people.

Suggestion: Hello, heart failure (Jane Heart Failure) is a common comorbidity in patients with hypertension. Seventy-five percent and 91 percent of all patients with heart failure had high blood pressure before the onset of the disease.

In the early stage of hypertension and heart failure, the diastolic function of the ventricles will gradually subside, which can lead to myocardial relative ischemia. In the advanced stage of comorbidities, the systolic function of the patient will be severely reduced, resulting in an enlarged heart, which can eventually develop left heart failure. Patients with left-sided heart failure may have symptoms such as palpitations, shortness of breath, cough, inability to lie flat, orthopnea (i.e., one of the phenomena in which patients are forced to sit up and breathe during sleep at night due to paroxysmal dyspnea), coughing and wheezing, blood in the sputum or pink foamy sputum, and increased heart rate.

Therefore, patients with hypertension and heart failure should be treated with antihypertensive drugs that can not only lower blood pressure, but also treat heart failure and have a protective effect on the heart. ACE inhibitors: captopril (Kaibotong), diuretics:

Hydrochlorothiazide (dihydrogramithia) and spironolactone (spironolactone). Patients with hypertension and heart failure should usually reduce their blood pressure to normal and avoid fluctuations in blood pressure, and at the same time pay attention to protecting the heart and choosing appropriate drugs to treat heart failure, so as to keep the condition stable and minimize the mortality rate of the disease.
