Clinical effects of pre-hospital emergency treatment combined with interventional therapy on acute myocardial infarction

Abstract

Objective To observe the clinical effects of pre-hospital emergency treatment combined with interventional therapy on patients with acute myocardial infarction, and to provide a reliable basis for the selection of treatment methods. Methods The clinical data from 600 patients with acute myocardial infarction admitted to General Hospital of Tongmei Group from March 2017 to March 2019 were retrospectively analyzed. And the patients were grouped by treatment methods. All patients were given emergency treatment before admission. A total of 317 patients with interventional therapy were included in the observation group, and 283 patients with conventional treatment were included in the control group. The absolute value of the difference in the heart rate, respiration, blood pressure, blood oxygen saturation and other indicators before emergency treatment and during transportation were observed and compared between the two groups. The number of defibrillation and hospital stay were compared between the two groups. The success rate of rescue, incidence of complications and rate of sudden death in the two groups were calculated. Results During delivery and before emergency treatment, the absolute differences of heart rate, respiration, blood pressure and other indicators of the observation group were superior to those of the control group, and the absolute difference of blood oxygen saturation was lower than that of the control group, however, the number of defibrillation and hospitalization time were less than those in the control group, with statistically significant differences (P< 0.05). The success rate of rescue in the observation group was 95.90%(304/317), significantly higher than the 81.98%(232/283) in the control group (P< 0.05), and the incidence of complications and sudden death rate were statistically lower than those in the control group (P< 0.05). Conclusions Pre-hospital emergency treatment combined with interventional therapy in patients with acute myocardial infarction can effectively improve clinical symptoms in a short period of time, which is beneficial to reducing the number of defibrillation, shortening the length of hospital stay, improving the success rate of rescue, and reducing the risk of related complications and sudden death.
