Introduction
Left heart failure refers to the failure of the left side of the heart. Symptoms and signs of left heart failure generally include dyspnea, cough, and dizziness. In addition, patients may also experience oliguria and kidney dysfunction, and should seek timely medical treatment at a hospital. Regular monitoring of electrolyte balance and body weight changes is recommended in daily life. Patients with diabetes or hypertension should also closely monitor their blood glucose and blood pressure levels.
Left heart failure refers to the condition in which the left ventricle of the heart fails to function properly. Symptoms and signs of left heart failure generally include dyspnea, cough, dizziness, etc. A detailed analysis is as follows:
1. Dyspnea
When left heart failure occurs, pulmonary congestion may develop, leading to pulmonary edema, which can cause varying degrees of breathing difficulty.
2. Cough
Left heart failure may lead to congestion of the alveoli and bronchial mucosa, thereby causing coughing. This often occurs at night or when lying down (especially in supine position), and usually improves when standing or sitting up.
3. Dizziness
Due to inadequate blood and oxygen supply to various tissues and organs caused by left heart failure, functional impairments may occur, resulting in symptoms such as dizziness and fatigue.
In addition, patients may also experience symptoms such as oliguria and kidney dysfunction. It is important for patients to seek timely medical evaluation and receive appropriate treatment under a physician's guidance. Regular check-ups are recommended, along with monitoring of electrolyte balance and body weight changes. Patients with diabetes or hypertension should also closely monitor their blood glucose and blood pressure levels.
