After treatment with medication and general nursing care, the condition was basically stabilized and the discomfort was relieved. Basic information] Female, 65 years old [Disease type] Right ventricular failure [Hospital] The First Affiliated Hospital of Xi’an Jiaotong University [Date of consultation] June 2021 [Treatment plan] Oral medication (Acarbose tablets, Metformin tablets, Irbesartan tablets, Furosemide tablets, Digoxin tablets, Nitroglycerin tablets) + Subcutaneous injections (Glycine Glycine Insulin injection) [Treatment period] Hospitalization for 7 days, and review in 1 month. Review in hospital 【Treatment effect】the condition is basically stable, chest tightness, breathlessness, double lower limb edema symptoms disappeared I. Initial consultation The patient reported that 4 days ago, without any cause, chest tightness, breathlessness, double lower limb edema, accompanied by dyspnea symptoms, mostly in activities or at night with obvious paroxysmal dyspnea, unable to lie down and fall asleep, and the effect of self-medication was not good. In order to seek further treatment, he came to our hospital for consultation. He asked about his medical history and was told that he had eaten less after the onset of the disease, had poor sleep at night, and had dry stools. Physical examination showed an enlarged heart murmur boundary, Qi heart rhythm, low heart sound, no valvular murmur and pericardial friction sound were heard, and the pulse rate was measured to be 58 beats/minute, which was relatively regular; both lower limbs were moderately edematous with finger-concave edema. An electrocardiogram was performed, which showed sinus rhythm, complete left bundle branch block, and ST-T changes. The patient was admitted to the hospital with a preliminary diagnosis of right ventricular failure. After the patient was admitted to the hospital, the immuno-serological examination was completed, and the B-type natriuretic peptide precursor was >35000.0pg/mL, which was higher than the normal value, and the diagnosis of right ventricular failure was clarified. After comprehensive consideration, the patient was instructed to take diuretic furosemide tablets, which can reduce the symptoms of double lower limb edema caused by water and sodium retention by promoting the discharge of body fluids, and the patient was also given oral nitroglycerin tablets for treatment, which can dilate blood vessels and thus reduce the burden on the heart. At the same time, the patient was given oral nitroglycerin tablets, which can dilate blood vessels, thus reducing the burden on the heart, and digoxin tablets, which can enhance the contractility of the heart, reduce the symptoms of chest tightness caused by right ventricular failure, and assist in better control of the condition. 7 days later, the patient’s condition was stabilized, and was discharged from the hospital. After the patient was admitted to the hospital, diuretic and cardiac medication was given to the patient, and on the 3rd day, the patient’s blood pressure and blood glucose level were normalized, and at the same time, the symptoms of chest tightness, breath-holding, and edema of both lower limbs were reduced. On the 5th day, the patient’s symptoms of chest tightness and breathlessness disappeared, and on the 7th day, the patient’s symptoms of bilateral lower extremity edema disappeared, the treatment effect was good, the patient was more satisfied, and no other abnormalities were found in the examination, so the patient was discharged from the hospital. One month after discharge, when the patient went to the hospital for follow-up, the blood pressure and blood glucose levels were measured again and remained in the normal range, and the symptoms of chest tightness, breathlessness and bilateral lower extremity edema did not recur. Precautions The patient’s condition has improved significantly after taking medication regularly under the doctor’s guidance, and I feel very pleased, but the following points need to be noted: 1. The patient needs to pay attention to keeping warm in daily life, avoiding catching cold, so as to avoid aggravation or triggering of the condition by cold stimulation; 2. Diet, the patient needs to pay attention to choosing light, low-fat food, avoiding oily, stimulating food, and paying attention to eating less and more meals, avoiding overfilling, so as to avoid overfeeding. Dietary aspects, patients need to pay attention to choose light, low-fat food, avoid greasy, stimulating food, at the same time, pay attention to small meals, avoid overfilling, so as not to aggravate the right ventricular failure; 3, the daily need to pay attention to ensure that adequate rest, avoid overwork, and also pay attention to maintain a relaxed mood, avoid excessive tension; 4, according to the doctor’s guidance, regular review, and also need to be closely detected in their own condition in the day-to-day, if there is any discomfort at any time for consultation. V. Personal perception Right ventricular failure is a more critical disease, if the patients in this case as regular medication, with life care can be better control of the condition, to avoid aggravation of the disease. At the same time, for their own underlying diseases, such as hypertension, diabetes mellitus, etc., also need to actively take drugs to control, for the treatment of right ventricular failure has certain benefits. In addition, once the dyspnea, dyspepsia, edema and other typical right ventricular failure manifestations, should be timely to the hospital to avoid delaying the disease or blind treatment of health hazards.
