To investigate the effectiveness of standardized emergency care procedures in emergency treatment of patients with ST-segment elevation myocardial infarction

Objective To explore the rescue effect of standardized emergency care procedures on ST segment elevation myocardial infarction patients. Methods A total of 110 patients with ST-segment elevation myocardial infarction diagnosed and treated in the emergency department of the Second Hospital of Jiaxing City from January, 2016 to March, 2018 were randomly divided into observation group and control group with 55 cases in each group. Patients in the control group were treated with routine emergency care procedures and patients in the observation group were treated with standardized emergency care procedures. The first-aid related indicators (ECG time, venous opening time, emergency stay time, first balloon dilatation time, and length of hospital stay) of the 2 groups were observed, the ST segment reduction rate and the nursing satisfaction degree within 3 hours. All patients were followed up for 6 months. The incidence of acute cardiac events (myocardial infarction, postinfarction angina, heart failure) and cardiac death was recorded in both groups. Results The patients in the observation group had shorter electrocardiogram time, intravenous opening time, emergency detention time, first balloon dilatation time, and hospitalization time than the control group (P<0.05). The rate of ST segment depression within 3 hours in the observation group was 63.6% (35/55), higher than 40.0% (22/55) of the control group, and the satisfaction rate of the observation group was 90.9% (50/55) higher than 74.5% (41/55) of the control group (P<0.05); after 6 months of follow-up, the incidence of acute cardiac events in the observation group was 12.7% (7/55) and the incidence of cardiac death was 0, while the control group were 29.1% (16/55) and 7.3% (4/55), respectively, P<0.05. Conclusion The standard emergency care procedure in ST segment elevation myocardial infarction patients can improve the patient's rescue effect, shorten the patient's rescue time, improve the patient's prognosis and nursing satisfaction, and is worthy of clinical application.
