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.

What medicine is used for acute heart failure?

The most common clinical manifestation of acute heart failure is severe dyspnea, hypoxia, and even changes in consciousness, which are very common in clinical practice. For treatment, morphine can be administered intravenously or subcutaneously to reduce patient agitation and relieve myocardial oxygen consumption. Secondly, plastic can be used for rapid intravenous push. Thirdly, vasodilators can be used, such as glyceryl trinitrate and sodium nitroprusside intravenous infusion. Fourthly, positive inotropic drugs can be used, such as dopamine and dobutamine. Additionally, cardiac glycosides, such as digoxin, can be used.

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.

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.

Is acute heart failure dangerous?

Acute heart failure is very dangerous in clinical practice. It is mainly caused by a sudden decrease in cardiac output, leading to insufficient perfusion in tissues and organs and acute blood stasis syndrome. The main clinical symptoms include severe respiratory distress, often accompanied by restlessness, profuse sweating, frequent coughing with pink frothy sputum, and in severe cases, sudden cardiac and respiratory arrest can occur. After the occurrence of acute heart failure, effective measures should be taken to alleviate symptoms such as respiratory distress. The most effective methods in clinical practice include strengthening the heart, promoting diuresis, and dilating blood vessels.

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.
