Chronic heart failure is the terminal manifestation and leading cause of death in cardiovascular diseases. Although there has been significant progress in the treatment of heart failure in China, the number of deaths from heart failure continues to rise. Coronary artery disease and hypertension have become the main causes of chronic heart failure. Rheumatic heart disease and valvular heart disease are also causes of chronic heart failure. Valvular heart diseases, such as mitral stenosis, mitral regurgitation, aortic stenosis, aortic regurgitation, pulmonary valve diseases, and tricuspid valve diseases, can all lead to heart failure. Additionally, chronic pulmonary heart disease and high-altitude heart disease also have certain regional prevalences in China.

Clinical manifestations of chronic heart failure

Chronic heart failure primarily includes left heart failure, right heart failure, and total heart failure. Clinically, left heart failure is the most common. The clinical manifestations of left heart failure primarily involve pulmonary congestion and reduced cardiac output, which can present as varying degrees of dyspnea, such as exertional dyspnea, orthopnea, and paroxysmal nocturnal dyspnea. Patients may experience coughing, expectoration, pink frothy sputum, fatigue, tiredness, dizziness, palpitations, and more. Right heart failure primarily manifests as gastrointestinal and liver congestion, causing abdominal distension, poor appetite, nausea, vomiting, and more. Total heart failure naturally includes the clinical manifestations of both left and right heart failure.

"Heart failure"

Heart failure is one of the most common complications of various organic heart diseases. It occurs when the heart's contractile force or diastolic function is impaired, preventing blood from being delivered to vital organs and throughout the body, leading to clinical symptoms caused by venous congestion and arterial ischemia, called heart failure. Diseases that can cause heart failure include coronary heart disease, pulmonary heart disease, rheumatic heart disease, hypertensive heart disease, and viral myocarditis. Patients with heart failure need to use effective medications to treat the diseases causing heart failure while minimizing the burden on the heart. They should adhere to a low-fat and low-salt diet, ensure sufficient rest, maintain regular bowel movements to prevent the acceleration of heart failure. (Specific medications should be administered under the guidance of a physician.)

Treatment methods for chronic heart failure

The treatment of heart failure mainly includes the following points. The first major category is etiological treatment, where we should actively manage all common diseases that may impair cardiac function, such as hypertension, coronary heart disease, diabetes, etc. The second category is to eliminate the factors that lead to heart failure, such as infections, especially respiratory infections. The third major category is for patients to pay attention to rest, control physical activity, avoid emotional excitement, and control sodium intake to reduce blood volume. The fourth category is drug therapy, which commonly includes the use of diuretics, ACE inhibitors, positive inotropic drugs, and β-blockers in clinical practice. (Medication should be administered under the guidance of a doctor.)

Chronic heart failure means

Chronic heart failure refers to a condition where the heart is unable to effectively pump blood throughout the body to meet the needs of vital organs, leading to a series of clinical symptoms caused by venous congestion and arterial ischemia. Symptoms include post-activity palpitations, orthopnea, swelling of the lower limbs, and enlarged liver. This condition causes great distress to patients and requires long-term use of effective medications to alleviate chronic heart failure. Patients with chronic heart failure need to ensure adequate rest, avoid overexertion, adhere to a low-salt diet, and limit the intake of spicy and greasy foods to prevent exacerbation of heart failure.

Treatment of Chronic Heart Failure

Chronic heart failure is a common and frequent disease in clinical practice, often caused by severe myocardial damage, which leads to insufficient myocardial contraction and results in inadequate peripheral blood supply. The primary principles of treatment are to reduce the heart's burden, enhance its contractile strength, decrease the heart's workload, and reduce the returning blood volume to alleviate the heart's burden. Treatment involves using vasodilators to decrease cardiac resistance, positive inotropic drugs to strengthen cardiac contraction, and diuretics and a low-salt diet to reduce cardiac volume and returning blood volume. By employing these methods, the symptoms of chronic heart failure can be improved.
