On physical examination, the patient was found to have percussive sounds in both lungs, coarse breath sounds and audible wet rales in both lungs, mild to moderate depressed edema in both lower limbs with hyperpigmentation, and electrocardiogram showed that the patient had atrial fibrillation with rapid ventricular rate, mildly shifted ST segments in some leads, and T-wave changes, and was admitted to the hospital with heart failure. After the diagnosis of heart failure was confirmed, I first made full communication with the patient and determined to take drug therapy as soon as possible. Because of the patient’s bilateral lower extremity edema, I prescribed furosemide tablets for the patient, this drug has diuretic effect, which can help improve the patient’s edema phenomenon. In addition, the patient was given digoxin tablets orally, which can slow down the heart rate, increase the ejection volume of the heart and the contraction capacity, which can improve the patient’s heart failure induced chest tightness, shortness of breath and other symptoms.

After the patient’s condition was under good control, he thanked me very much for the treatment, and I was very happy to see that the patient was discharged from the hospital happily. When discharged from the hospital, I advised the patient to take regular work and rest, combine work and rest, ventilate the house appropriately, maintain the appropriate temperature and humidity, exercise properly in conjunction with the physical condition, and eat more egg custard, congee with yam, fresh milk, fish and other nutritious and easy-to-absorb diets. I tell patients that a healthy diet and lifestyle can help their condition improve. In addition, I also explained to the patient that discharge does not mean that the disease is cured, and that the medication I prescribed should be taken according to the course of treatment, and that if he felt any abnormal symptoms, he should consult a doctor in time to review his condition. Fifth, personal perception with age, the body’s functions will be reduced accordingly, easier to secondary other diseases, as in this case of 80-year-old female patients, the patient itself there is hypertension, diabetes, this examination is accompanied by heart failure, but because the patient regularly take medication, and heart failure, the disease was found in a timely manner, did not secondary to other serious complications, so the condition of the patient’s systematic treatment to recover!
