There are several compensatory methods for acute heart failure.

The first is mechanical ventilation, including non-invasive mechanical ventilation and tracheal intubation. Mechanical ventilation is commonly referred to as assisted breathing with a ventilator.

The second is continuous renal replacement therapy, commonly known as total ultrafiltration, which can be used to remove excess fluid and metabolic waste from the body.

The third is intra-aortic balloon counterpulsation, which can effectively improve myocardial perfusion, reduce myocardial oxygen consumption, and increase cardiac output.

The fourth is extracorporeal membrane oxygenation, commonly known as ECMO, which provides external cardiopulmonary support when the heart cannot maintain systemic perfusion or when the kidneys cannot adequately exchange gases.

The fifth is the implantable left ventricular assist device, which can maintain peripheral perfusion during acute heart failure and reduce myocardial oxygen consumption, thus reducing cardiac injury.

These five methods can provide compensatory treatment when drug therapy is ineffective for patients with acute heart failure.

What is a good diet for heart failure?

Heart failure is one of the most common complications of various organic heart diseases. After the onset of heart failure, it is necessary to use effective medications to treat the primary disease causing the heart failure. At the same time, methods such as cardiotonics, diuretics, and vasodilators should be used to reduce the burden on the heart as much as possible and correct heart failure in a timely manner. Patients with heart failure should rest, keep calm, and avoid overexertion in daily life. Their diet should primarily consist of low-fat and low-salt foods, and they should abstain from smoking and drinking alcohol. They should avoid spicy foods, pickled foods, and overly salty foods. Eating overly salty foods can increase blood volume, increase the burden on the heart, and worsen heart failure. (The use of medications should be conducted under the guidance of a professional doctor.)

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.

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.

The basic mechanisms of heart failure

Heart failure is not an independent disease; it can be caused by various factors, such as myocardial infarction, cardiomyopathy, and various myocarditis, which lead to changes in the heart structure and subsequent cardiac dysfunction. Heart failure is mainly due to a disturbance in the heart's contractile function or diastolic function, which prevents the heart from adequately ejecting the returning blood volume. This results in pulmonary congestion, systemic circulation congestion, and a series of syndromes caused by insufficient arterial perfusion.

Which department should I go to for heart failure?

Heart failure primarily includes left heart failure, right heart failure, and total heart failure. Patients should visit the cardiology outpatient clinic. Left heart failure mainly manifests as pulmonary congestion, which can cause varying degrees of breathing difficulty, coughing, expectoration of pink frothy sputum, palpitations, and fatigue. Right heart failure primarily appears as liver congestion and other symptoms related to the digestive system, such as nausea, vomiting, and gastrointestinal discomfort. Total heart failure includes symptoms of both left heart failure and right heart failure, and medical attention should be sought promptly after the onset of heart failure.
