Heart failure
Heart Failure Drug Therapy
Due to some myocardial diseases that cause damage to the myocardium, or other reasons that increase the heart's load, heart failure may occur. Clinical treatment involves strengthening the heart and promoting diuresis, improving blood vessel function, increasing the heart’s contractility, reducing the heart’s resistance, and decreasing the volume of blood returning to the heart. Through these effective drug treatments, heart failure can be corrected. Patients with heart failure should avoid excessive fatigue and maintain a low-salt diet to prevent increasing the burden on the heart.
Clinical manifestations of chronic heart failure
Chronic heart failure primarily includes left heart failure, right heart failure, and total heart failure. Left heart failure can present with varying degrees of respiratory difficulty, such as exertional dyspnea, orthopnea, and paroxysmal nocturnal dyspnea, etc. Secondly, symptoms can include coughing and expectorating, coughing up pink frothy sputum, and patients may experience fatigue, dizziness, and palpitations, among others. Right heart failure mainly manifests as gastrointestinal symptoms, such as abdominal distension, poor appetite, nausea, vomiting, etc. Total heart failure encompasses the clinical manifestations of both right and left heart failure.
The basic etiology of chronic heart failure
Chronic heart failure is one of the most common complications of various organic heart diseases, and there are many causes of chronic heart failure. The main reason is due to primary diseases that have not been effectively treated. Long-term myocardial ischemia, hypoxia, excessive fatigue, emotional excitement, overeating, too full, constipation, and other reasons increase the cardiac burden, leading to chronic heart failure. People with organic heart disease must treat the primary disease under the guidance of a doctor. At the same time, pay attention to rest, avoid emotional excitement, eat easily digestible food, maintain a low-salt, low-fat diet, and ensure smooth bowel movements to prevent increasing the cardiac burden and causing heart failure.
Causes of acute heart failure include
Most patients with acute heart failure have a history of heart disease, and the common causes mainly include: 1. Acute myocardial necrosis or damage, such as acute coronary syndrome, peripartum cardiomyopathy, and myocardial damage caused by drugs or toxins, including sepsis-induced myocardial damage. 2. Acute exacerbation of chronic heart failure due to infection or other stressful factors. 3. Acute hemodynamic changes, mainly including conditions like cardiac tamponade, hypertensive crisis, aortic dissection, and acute valvular regurgitation, all of which can lead to acute heart failure.
Causes of Acute Heart Failure
The main causes of acute heart failure include coronary heart disease, valvular disease, hypertension, and cardiomyopathies, such as toxic cardiomyopathy or hypothyroidism-related cardiomyopathy, as well as idiopathic cardiomyopathy. Myocarditis and arrhythmia-related causes can also lead to heart failure, but there are often triggers present clinically. Common triggers include poor treatment compliance, arrhythmias, anemia, infections, myocardial ischemia, excessive fluid intake, poor dietary control, and increased cardiac output, such as during strenuous activity and pregnancy, which can lead to increased cardiac output and cause heart failure. Conditions such as excessive fluid volume, hypertension, hyperthyroidism, and pulmonary embolism can also trigger heart failure.
Can people with chronic heart failure smoke?
Patients with chronic heart failure should not smoke, as smoking can enhance the excitability of the sympathetic nervous system. Increased excitability of the sympathetic nervous system releases norepinephrine, elevating norepinephrine levels. This can cause peripheral vasoconstriction, increase the afterload on the heart, and accelerate heart rate. Both of these effects can increase myocardial oxygen consumption. Furthermore, norepinephrine has a direct toxic effect on myocardial cells, promoting myocardial cell apoptosis and participating in the pathological process of ventricular remodeling. Moreover, excitement of the sympathetic nervous system can also enhance myocardial stress, potentially promoting the occurrence of arrhythmias. Therefore, patients with chronic heart failure should not smoke.
How is heart failure treated?
Heart failure is very common in clinical settings. The main treatments include strengthening the heart, diuresis, and vasodilation for symptomatic treatment. A mask or high-flow oxygen can be used if the patient's heart failure symptoms are difficult to correct, or if cardiogenic shock occurs. Aortic balloon counterpulsation and tracheal intubation can be adopted, with ventilator support for ventilation, and blood dialysis and other symptomatic supportive treatments can be used. Another point is to actively control or eliminate the causes of heart failure, etc.
Why does heart failure cause edema?
Edema caused by heart failure is mainly due to heart dysfunction, resulting in systemic circulation, venous congestion, and excessive fluid accumulation in the body's tissue spaces. The primary cause is right heart failure or total heart failure, and some special cases of pericarditis. The edema caused by this type of heart failure is often symmetrical, indenting, and sagging, and usually worsens with activity and lessens with rest. The common locations for fluid accumulation are in the sacral and perineal areas, while bedridden patients often show it in the ankle area. In severe cases, patients may experience generalized edema, and even develop ascites and pleural effusion. This condition is known as heart failure, and the type of edema it causes is called cardiogenic edema.
What causes acute heart failure?
Acute heart failure can occur in diseases of the heart itself, as well as in other serious diseases that lead to heart failure. Common cardiac diseases include severe arrhythmias, cardiomyopathy, and myocardial infarction. If these diseases are not well treated, they can cause acute heart failure. Other diseases can be seen in cases such as drug poisoning, severe anemia, severe infection, and during the treatment of other diseases when excessive use of fluids increases the burden on the heart, leading to acute heart failure.
How to check for heart failure?
Heart failure is a relatively common cardiac disease in our daily lives, and patients often exhibit symptoms such as shortness of breath, difficulty breathing, and fatigue. So, how should heart failure be diagnosed? Generally, the following are common tests: First, an echocardiogram. An echocardiogram is a very practical and non-invasive test that can determine the presence of heart valve diseases, cardiomyopathy, and other conditions, as well as assess the heart's pumping function; Second, blood tests. For example, blood tests for electrolytes and BNP, or brain natriuretic peptide, can determine the presence of heart failure; Third, chest CT or X-rays. These can identify manifestations of pulmonary congestion caused by heart failure.
