Heart failure is relatively common in clinical settings, primarily divided into left heart failure, right heart failure, and global heart failure. The clinical manifestations of left heart failure are mainly reflected in symptoms of pulmonary congestion. It can present as varying degrees of dyspnea, cough, expectoration, palpitations, and fatigue. Right heart failure is mainly due to obstruction of the inferior vena cava flow, leading to increased venous pressure and capillary pressure. This causes plasma components to extravasate and ultimately leads to the formation of ascites. Global heart failure includes the symptoms of both left and right heart failure. Therefore, it is essential to seek medical attention promptly after heart failure occurs.

Can heart failure cause suffocation?

Heart failure is caused by various reasons leading to the heart's blood supply being relatively or absolutely insufficient, causing a series of pathological and physiological disorders in patients. Patients often manifest symptoms like difficulty breathing, tightness in breath, and even a feeling of suffocation. However, generally, the symptoms caused by heart failure are not these. This is because suffocation occurs due to airway narrowing or the narrow space around the patient, leading to insufficient oxygen intake, causing a series of syndromes. Therefore, although people with heart failure feel suffocated, they are not actually suffocating; it is just a manifestation of inadequate circulatory supply.

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 people with heart failure eat fish?

Patients with heart failure can eat fish, as fish contains a large amount of high-quality protein, vitamin B, trace elements, and minerals. Consuming fish can increase the high-quality protein the body needs, enhance the body's immunity and disease resistance. Especially for patients with heart failure, who suffer from chronic myocardial ischemia, need nutritional support. When preparing fish, it should not be made too salty, as patients with heart failure should follow a low-salt diet. If the fish is too salty, consuming it in excess could exacerbate heart failure. Preparing fish in a lighter way, such as making fish soup, can not only supplement the body's high-quality protein but also be easier to digest.

Can acute heart failure be fatal?

The answer is affirmative. Acute heart failure is a very dangerous and serious clinical syndrome in cardiovascular diseases. Generally speaking, it is characterized by a significant decrease in the cardiac contractile function and an increased cardiac load, leading to a sharp drop in acute cardiac output, a sudden increase in pulmonary circulation pressure, and increased resistance in peripheral circulation. This results in acute pulmonary congestion and pulmonary edema and may be accompanied by insufficient perfusion of tissues and organs and a clinical syndrome of cardiogenic shock. Therefore, it can be fatal, and if not addressed promptly or adequately, it often has a high mortality rate.

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.)
