Introduction
Left heart failure refers to the failure of the left side of the heart. The typical auscultatory findings in left heart failure are crackles and wheezing. Left heart failure usually results from inadequate compensatory function of the left ventricle, which may lead to excessive pressure and volume overload on the heart, resulting in decompensated cardiac function. This manifests as symptoms such as dyspnea and cough. It can affect vital organs throughout the body, leading to a decline in the patient's quality of life.

Left heart failure generally refers to heart failure caused by inadequate compensatory function of the left ventricle, which may lead to excessive pressure and volume load on the heart, resulting in decompensated cardiac function. Symptoms include dyspnea, cough, and sputum production. It can affect vital organs throughout the body, leading to a decline in the patient's quality of life. The condition is typically detectable via stethoscope, characterized by the presence of moist rales and wheezing, along with a significantly increased respiratory rate. If pleural effusion is present, diminished breath sounds may be heard.
Treatment for left heart failure should be conducted under a doctor's guidance, using medications such as bisoprolol-amlodipine tablets or furosemide tablets. Patients should ensure adequate rest and maintain good sleep quality, avoiding prolonged late-night hours. A calm state of mind is recommended, avoiding excessive mental stress. Dietary adjustments are important—spicy and greasy foods such as chili peppers and hot pot should be avoided, while fresh fruits and vegetables should be consumed more frequently.
