The earliest symptom of left heart failure is mainly exertional dyspnea.
Left heart failure is usually due to coronary heart disease, hypertension and other factors caused by heart failure. In the early stage of the disease, the symptoms of dyspnea will appear after labor, and as the disease progresses, nocturnal paroxysmal dyspnea will appear, and some patients will suddenly be awakened after going to sleep because of breath-holding, so as to take a sitting position to alleviate the symptoms.
When acute pulmonary edema occurs, it proves that the left heart failure is in an advanced stage, which is the most serious symptom.
Usually when there is an acute attack of left heart failure and obvious fluid retention, diuretics such as spironolactone can be applied, while early and adequate application of drugs such as enalapril and chlorosartan can relieve symptoms and delay heart failure symptoms, etc., while long-term application of drugs such as metoprolol can alleviate symptoms and improve the prognosis.
When the above symptoms occur, it is recommended to consult a regular hospital in a timely manner, after a clear diagnosis and active treatment.
