(Disclaimer: This article is for scientific purposes only, in order to protect the privacy of patients, the relevant information in the following content has been processed) Abstract: The patient is a female, 67 years old, 1 month ago, without any triggers, edema, small amount of urine, and edema gradually aggravated, more than 10 days ago, paroxysmal chest tightness, dyspnea, combined with the abnormal changes in the electrocardiogram, physical examination, and immuno-serology, the initial diagnosis of the right ventricular failure. After drug treatment, the patient’s condition was basically stabilized and the symptoms of edema and chest tightness disappeared. Basic information] Female, 67 years old [Type of disease] Right ventricular failure [Hospital] The First Affiliated Hospital of Xi’an Jiaotong University [Date of consultation] February 2021 [Treatment plan] Oral medication (furosemide tablets, spironolactone tablets) + intravenous infusion (deacetyl furfuryl glucoside injection) [Treatment cycle] Hospitalization for 7 days, 1 month later, review in the hospital [Effect of treatment] Condition is basically stabilized, and the patient’s edema and chest tightness disappeared, The patient reported that he had edema a month ago without any cause, which was sometimes mild and sometimes severe, and the amount of urine was small, and the edema gradually worsened. 10 days ago, the patient had paroxysmal chest tightness, which often worsened when he was active, and was accompanied by symptoms of not being able to lie down at night, and dyspnea. Physical examination of the patient showed a heart rate of 105 beats per minute, rhythmic, without valvular murmurs and pericardial friction, a pulse rate of 105 beats per minute, regular pulse rate, abdominal percussion of drums, and second-degree depressed edema of both lower limbs. The electrocardiogram showed sinus rhythm and ST-T segment changes, suggesting the presence of insufficient blood supply to the heart, and the immuno-serological examination showed that the B-type natriuretic peptide precursor was 470.2pg/mL. Combined with the patient’s clinical manifestations, medical history, and physical examination, the patient could be diagnosed with right ventricular failure, and was admitted to the hospital for treatment. Second, the treatment process After communicating with the patient, the program of conservative treatment was determined. Firstly, the patient was given oral diuretics furosemide tablets and spironolactone tablets, which can promote the liquid discharge in the body, reduce the symptoms of chest tightness and edema caused by sodium retention in the body, and at the same time, avoid the electrolyte imbalance caused by the low discharge of potassium ions in the body. Moreover, the patient was given deacetyl furfuryl glucoside injection intravenously, which can enhance myocardial contractility to avoid the decrease of myocardial contractility caused by right ventricular failure. The patient’s condition was stabilized in 7 days after admission, and the patient was discharged from the hospital and visited the hospital 1 month after discharge. If there is any discomfort, consult the doctor at any time. Third, treatment effect After regular medication and general conditioning treatment, the patient’s chest tightness, double lower limb edema symptoms disappeared, blood pressure was at the normal level, and no other abnormalities were seen on physical examination, the treatment effect was good, and the patient was more satisfied with it, and was discharged from the hospital. The patient was discharged from the hospital one month later, the patient’s spirit was good, normal urination and defecation, and there were no symptoms of chest tightness and lower limb edema, so the patient was advised to continue the drug treatment and to monitor his condition in time, and to consult a doctor if he was not feeling well. Precautions The patient’s condition was basically stabilized after regular drug treatment and general nursing, I feel very pleased, but need to pay attention to the following matters: 1, the patient needs to take medication regularly under the guidance of the doctor, to avoid stopping or reducing the amount of medication on their own, so as not to aggravate the condition. At the same time in the process of medication need to pay attention to observe their own situation, if there are symptoms of discomfort, consult a doctor at any time; 2, the patient needs to ensure that adequate rest, to be cardiac function recovery can be taijiquan, walking and other low-intensity exercise, to enhance physical fitness; 3, right ventricular failure patients need to be bedridden for a long time, need to observe the patient’s skin at any time, clean the skin on time, as well as turn over, to avoid the emergence of pressure ulcers. The right ventricular failure belongs to a kind of heart failure, if not treated in time, it can cause serious damage to the patient’s body. In this case, the patient was treated timely, after drug treatment and general care, chest tightness, double lower extremity edema and other symptoms disappeared, and the condition was significantly improved, and I was very pleased. Therefore, it is recommended that people who have symptoms of discomfort go to the hospital in a timely manner to avoid avoiding medical treatment, resulting in aggravation of the condition.
