Although the occurrence of heart failure is a serious threat to the patient’s life and requires timely treatment, the possibility of stenting when suffering from heart failure should be determined by the patient’s specific condition. In addition, stent placement cannot treat heart failure, but can only be used to treat the primary condition of coronary heart disease. One: heart failure is the end-stage manifestation of various heart diseases. Patients with coronary heart disease who already suffer from heart failure and whose condition progresses more seriously must be hospitalized in a large hospital in time to receive systematic treatment after a clear diagnosis, and it is best to undergo coronary angiography after heart failure is controlled and then consider whether to put stents for coronary heart disease. Secondly, once heart failure occurs, it may deteriorate continuously. Symptomatic treatment measures should be taken as soon as possible, and medication should be applied to cardiotonic, diuretic and vasodilator drugs as prescribed by the doctor. If the cause of heart failure is caused by coronary artery disease, the treatment of the original cause can lead to better control of heart failure. Third: the degree of coronary artery lesion is an important reference basis for the treatment of coronary heart disease. According to the results of coronary angiography, patients with coronary artery disease can be treated with drugs, stent intervention and coronary artery bypass grafting. Stent placement can be used to relieve the lack of blood supply to the heart muscle and prevent myocardial infarction and sudden death, but it cannot completely solve the problem of coronary atherosclerosis and requires the cooperation of patients in all aspects to have good results. Fourth: Patients with coronary heart disease accompanied by heart failure, if stenting is performed, should take medication under the guidance of doctors to consolidate the efficacy and cooperate with scientific nursing care measures. Diet should be kept low salt, low fat, low cholesterol, limit daily calorie intake, eat more vitamin-rich foods, eat less and more meals, and avoid spicy stimulation. Fifth: In severe cases, bed rest should be strictly applied. In the non-acute stage, some simple exercises such as walking and tai chi can be performed according to medical advice. Family members and medical staff should give more care to the patient and provide timely psychological guidance to help them establish confidence in overcoming the disease. Sixth: whether stents can be put in with heart failure is not absolute. After correcting heart failure, doctors may make a comprehensive assessment according to the degree of coronary lesions and other factors, and then decide whether patients need to undergo stenting after the assessment. Treatment for the primary disease is positive for improving the condition of heart failure patients and reducing their mortality.
