Heart failure in clinical practice can be divided into left heart failure, right heart failure, and total heart failure. The symptoms of left heart failure primarily manifest as pulmonary congestion, including varying degrees of dyspnea, cough, coughing up pink frothy sputum, palpitations, fatigue, etc. As for right heart failure, it mainly shows as gastrointestinal congestion, with symptoms such as nausea, vomiting, loss of appetite, etc. Once heart failure symptoms appear, the patient must seek medical attention promptly, actively treat the primary disease, correct the symptoms and signs of heart failure, and then avoid excessive physical activity, infections, and other triggers that could exacerbate heart failure.

Compensatory mechanisms of acute heart failure

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.

Can heart failure be cured?

We say that some early-stage heart failure can be cured, such as peripartum cardiomyopathy and thyrotoxic cardiomyopathy. If discovered and treated early, there is hope for a cure. However, most heart failure cannot be cured. Although some psychological failures cannot be cured, if patients can receive early treatment and effective treatment, take their medication on time, and have regular check-ups as advised by their doctor, most heart failure can still be controlled or alleviated. However, if heart failure is detected and not actively treated, even mild heart failure may gradually worsen, or even become end-stage heart failure.

Acute heart failure typical symptoms

The typical symptoms of acute heart failure include sudden severe difficulty breathing, increased respiratory rate, and patients generally presenting a forced sitting position, with pale, grayish complexion and cyanotic lips. They often have profuse sweating, restlessness, frequent coughing, and coughing up pink frothy sputum. The condition can be critical, leading to consciousness disturbances due to lack of oxygen. Once acute heart failure occurs, active treatment is essential. The most common clinical approaches include strengthening the heart, diuresis, and vasodilation for symptomatic active management.

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.

Clinical manifestations of heart failure

Heart failure is divided into left heart failure, right heart failure, and total heart failure. Left heart failure mainly manifests as exertional dyspnea or nocturnal paroxysmal dyspnea. It is often accompanied by palpitations, orthopnea, coughing, coughing up pink frothy sputum, accompanied by palpitations, fatigue, etc. Right heart failure primarily presents with symptoms of the digestive system, such as abdominal distension, nausea, vomiting, edema, oliguria, etc. Once heart failure occurs, active treatment must be administered. In clinical practice, treatments mainly include cardiotonics, diuretics, vasodilators, and other symptomatic treatments.
