Left heart failure occurs when the heart cannot pump enough blood. This leads to oxygen deficiency for organs in the body. If not treated promptly, left heart failure can lead to complications such as liver failure, kidney failure, arrhythmia, or risk of death.
What is left heart failure?
Heart failure is a condition in which the ability to supply the heart of the heart to the body decreases, starting from exertion and then during rest. Heart failure can be classified into right heart failure, left heart failure and whole heart failure.
Left heart failure, a common form of heart failure , is responsible for bringing oxygen -rich blood from the lungs to other parts of the body. When the heart is weak, its functions will decrease, causing serious effects on the patient's health.
Left heart failure has many different classifications. According to the progression of the disease, there is left left heart failure and chronic left left heart failure.
Left -grade heart failure is a sudden appearance of signs and symptoms of left heart failure, may be the first or recurrent. This is a life -threatening situation, requiring immediate emergency intervention.
Chronic fruit failure is prolonged and difficult to completely overcome. This disease is a result of damage or heart dysfunction leading to an incompetent ventricular to receive and push blood. Chronic left heart failure is usually the most common form of heart failure.
Causes of Left heart failure's disease
All factors that lead to blood stagnation in the left heart or left -right heart work excessively can contribute to the cause of left heart failure. The common causes include:
Aortic hypertension: This is the most common cause of left heart failure. So why does hypertension cause left heart failure? Hypertension increases the pressure of blood vessels, limits blood pressure from left ventricular, and increases the pressure on the heart. This requires the left and right heart to contract stronger to overcome the restriction, gradually leading to heart failure. Strong> When the mitral valve is open, each time the heart contracts, the blood will enter the left atrial instead of normal circulation. This forced the heart to contract stronger and longer to respond. For a long time, this will cause left heart failure. Return to left. When the aortic valve is open, the amount of blood returns to the left ventricle is reduced, causing the heart to work more and more strongly contracting to compensate for the loss of blood. As a result, the left heart gradually becomes weaker.
In addition, myocardial can also be damaged in some other situations such as myocardial ischemia, myocardial hypertrophy, myocarditis due to low or bacterial infections. , and other myocardial diseases. Other causes include pulmonary turbocharger, aortic stenosis, congenital heart, dramatic tachycardia on ventricular, atrial crazy, atrial fibrillation, bronchial asthma and diabetes. >
Symptoms of Left heart failure's disease
Mechanical symptoms
Symptoms of shortness of breath are typical functional impairment.
Difficulty breathing: in normal condition, one can also feel short of breath when strengthening strength and will recover quickly when resting. However, for patients with heart failure, shortness of breath can appear even when trying a little and it takes longer to recover. : In the lying position, the blood is more concentrated in the chest area, creating a greater pressure on the heart. This is an important symptom and often appears early in heart failure. Some patients may have symptoms of cough when lying, and also considered as a form of shortness of breath. This phenomenon appears quickly, just a few minutes after the patient lies, and reduces when sitting up or lifting the pillow. Nhan suddenly had to wake up a few hours after sleeping, feeling worried, difficulty breathing and stifling. The patient must lift the pillow higher or sit up to breathe. In this shortness of breath, bronchial spasms may occur. Different from difficulty posture, shortness of breath requires a longer period of time to reduce symptoms. than. In this case, the pulmonary capillary pressure increased significantly, causing a synchronization between ventilation and blood supply. In addition, shortness of breath can also be reduced by lung function. Sweat, breathing quickly, respiratory muscles shrink, and there is noise from bronchial. This is a serious acute condition, life -threatening of the patient. The cause comes from the sudden increase in pulmonary capillary pressure due to acute left heart failure.
Other symptoms include:
cough: Coughing usually takes place at night or when the patient is exertion. Usually a dry cough, but sometimes it can also be accompanied by sputum release, including blood. , the patient may experience weak feeling, face, and feel soft limbs. Li> often urinating at night and urinating a little quantity. P> Physical symptoms
When examining the heart: Looking, touching the heartbeat to the left. Small and dim heart sound, tachycardia, can see the sound of non -left horse. The mild murmur of the heart, less orchid. In case the heart attack can hear a lot of hiss and moist ram in the two lungs, in the pulmonary edema hears many large moisture, small seeds rising from the bottom of the lungs all over the two waste. > Measuring blood pressure: In most cases, the maximum blood pressure decreases, the minimum blood pressure is normal, so the number of blood pressure is usually small.
Fruit heart failure is dangerous Are not?
With the above symptoms, is the left heart failure dangerous? Timely detection and treatment play an important role in slowing down the progression of left heart failure, controlling symptoms and preventing hidden complications. Conversely, if you do not receive proper intervention, left heart failure can cause consequences such as:
Heart rate incidents such as ventricular tachycardia and atrial fibrillation ... >
pulmonary hypertension.
Suddenly or death. Li>
Depression or anxiety.
People at risk for Left heart failure's disease
Men have a higher incidence of left heart failure than women. The risk of increasing in men aged 50-70, especially for those who have experienced myocardial infarction. Other ethnic groups.
People with myocardial disease, congenital heart defects, or valve disease. Non -steroid anti -inflammatory drugs (NSAIDs), ...
People with bacterial or viral infections: Some bacteria and viruses are likely to cause heart muscle damage. < /Li>
Prevention of Left heart failure's disease
To prevent the risk of left heart failure, the following measures are needed:
Regular health checks to promptly detect abnormal signs and receive timely treatment. If there is an abnormal symptom, a medical facility is needed to check.
Apply a healthy diet, limited salt, sugar and fat consumption limits. Increase the diet of green vegetables, fruits, and whole grains. Especially important to control blood sugar if diabetes.
Ensure to maintain weight at an appropriate level. Checking weight regularly, any abnormal weight gain may be related to water storage in the body.
exercise and exercise regularly with intensity suitable for cardiovascular health. Should consult a doctor to choose the appropriate exercise regime.
Limit stress, maintain optimism and fun. In addition, it is necessary to reduce alcohol consumption and stop smoking. Stress can increase heart rate and cause disorders. Alcohol and tobacco can cause vascular damage, reduce blood oxygen concentration and increase blood pressure.
Controlling related diseases such as hypertension, diabetes, asthma, and chronic obstructive pulmonary disease (COPD).
Use the drug as directed by the doctor, do not increase, decrease the dose, do not quit the dose, do not use the prescription of others. When there are abnormal symptoms when taking the drug, it is necessary to notify the doctor.
Diagnostic measures for Left heart failure's disease
To make a diagnosis of left heart failure, the doctor will rely on clinical symptoms and combine with:
Basic blood tests to assess the patient's overall condition, as well as related disorders and pathologies such as anemia, blood lipid disorders, and diabetes. >
BNP test and derivatives: When heart failure, the heart wall is stretched and produces many Pro-BNP, then transformed into NT-Probnp and BNP. These tests may detect signs of heart failure early, even before clinical symptoms, and high sensitivity. BNP plays a role in screening for patients, giving diagnosis and eliminating the causes of acute shortness of breath, as well as helping to monitor the treatment process and forecast the progressive situation of the disease. Other blood tests to detect the cause of heart failure, including thyroid hormone tests, and anemia indicators. Kidney function, and liver function.
chest X-rays, coronary angiography, echocardiography, and electrocardiograms, as well as use exertion methods. Some other methods include cardiac ventilation, physiological electrical research, cardiac testing by nuclear medicine (Hall stress test). X-ray images can display hypertrophic heart, especially on the left heart chamber, and the left ventricular ventricular manifests itself through the supply of the shape of the lower left and extended lower left arc. Both lungs are the most dimly lungs.
Left heart failure's disease treatments
Treatment of left heart failure includes:
Rest mode: It is important to reduce the intensity of the heart. The appropriate training and rest regime depends on the degree of heart failure. Patients with mild heart failure can perform physical exercise but should avoid excessive activity. In case of more severe heart failure, it is necessary to minimize exercise. Patients with heart failure need to apply a diet to reduce salt or a diet completely depending on the degree of heart failure. The burden for the heart. The amount of oral fluid needs to be limited from 500-1000ml per day depending on the degree of heart failure. Difficultyness and limit pulmonary contraction. Stress, stop using drugs that reduce the contractions of the heart muscle under the instructions of the doctor (for example, the sympathetic beta blockers are not used to treat heart failure, verapamil, disopyramid, etc.) . Avoid using water retention drugs such as corticosteroids, NSAIDs, ... , infection, and other related issues. Evaluating and identifying the cause of the disease is an important step for thorough treatment:
If heart failure is anemia, it is necessary to identify the cause and conduct specific treatment, as well as compensate for the lack of blood. of prolonged arrhythmia, treatment for arrhythmia should be properly applied, including the use of drugs or pacemaker placement. Heart or birth defects, it is necessary to consider the ability to intervene through the skin or surgery to fix malformations, replace heart valves, and treat.
Good control of hypertension , especially when there are necessary causes to conduct thorough treatment. Two -chamber heart, this method is indicated for patients with severe heart failure. The left-level left is in need of other special interventions, such as placing the AABP bully (IABP) or using an extracorporeal membrane oxygenator (ECMO). The patient
how long the heart failure depends on the cause of the heart failure. If there is timely intervention, some cases of chronic heart failure can be overcome. Causes of recovery heart failure such as valve disease, hypertension, myocardial disease due to alcohol, myocardial disease ... if received properly treatment.
The prognosis of left heart failure depends on a series of factors, including:
The age of the patient. > The patient's reaction to treatment.
High NT-Probnp level. In addition, the history of myocardial infarction or chronic obstructive pulmonary disease (COPD) is also important prognosis. >
