There are more manifestations of heart failure aggravation, and the more common ones include dyspnea, generalized swelling, pleural effusion, and so on. 1. Dyspnea: heart failure may affect the lungs, leading to increased lung infection, thus affecting normal breathing, manifested as shortness of breath, dyspnea, and in severe cases, sitting breathing. 2. Generalized edema: after heart failure seriously affects the heart function, it will easily lead to obstruction of venous return and obvious reduction of urinary output, and it will affect the cardiac output and lead to reduction of renal blood flow, so the patients will have symptoms of swollen limbs, puffy eyelids and facial edema. 3. Pleural effusion: mainly due to severe heart failure, resulting in a large amount of exudate fluid in the thoracic cavity, such as can not be discharged in a timely manner, the amount of more than the drainage capacity of the pleural lymphatic vessels will remain in the local area, resulting in pleural effusion, the patient will often feel tightness in the chest. If there are several situations above, it means that the heart failure is obviously aggravated, at this time the patient should pay attention to, and regularly check and monitor the cardiac function, and then according to the diagnosis results of the appropriate adjustment of the treatment program.
