Evaluation of acute myocardial infarction

Patients with acute AMI are extremely unstable, and their lives are often threatened by malignant arrhythmia, acute left heart failure and cardiogenic shock. Therefore, it is the key to reduce acute left heart failure and mortality to monitor the changes of patients' condition at an early stage and take appropriate intervention measures in time to prevent the occurrence of the above serious situation. The data in this group show that the incidence of acute left heart failure in AMI patients with risk index ≤30 is 7.9%, and the mortality rate is 5.3%. However, the risk indexes of AMI patients over 30 years old were 26.2% and 65,438+09.0%, respectively, with significant differences (all P 30, nurses must strengthen patrol, closely observe the changes of heart rate and blood pressure, and prepare emergency medicines and instruments at any time. Once the signs of myocardial ischemia and hypoxia are aggravated, they should be rescued in time to avoid complications such as malignant arrhythmia. The data in this group show that AMI patients with risk index > 30 are more common in the elderly, with large myocardial infarction area and multi-vessel coronary angiography. Therefore, ECG monitoring should be continued for more than 1 week after admission, and the changes of heart rate, heart rhythm, blood pressure and R should be closely observed, especially for patients with increased heart rate and decreased SBP, so as to find possible serious arrhythmia, acute left heart failure and cardiogenic diseases in time. Because of the acute onset and serious illness of AMI, patients are often agitated by pain and fear. Therefore, while monitoring the change of illness and doing a good job in first aid, we should do a good job in psychological care, strengthen communication with patients, remind patients that bad emotions are the risk factors leading to the onset of AMI, guide them to master the methods of self-regulation of emotions, eliminate patients' fear, enhance their confidence in overcoming the disease, actively cooperate with treatment, and guide patients to gradually recover [3]. Patients with AMI need lifelong health care after their clinical cure. When leaving the hospital, patients and their families should be instructed to pay attention to diet regulation, life rules, combining work with rest, quitting smoking and drinking, maintaining emotional stability and ease of mind, and developing good health behaviors around the theme of enhancing self-care ability and disease prevention and health care, so as to improve the quality of life and prolong life.
