Clinical epidemiological study on suspected acute myocardial infarction patients in outpatient and emergency department

Objective To investigate the clinical treatment of suspected acute myocardial infarction (AMI) patients in outpatient and emergency departments in Suzhou area, and provide reliable clinical epidemiological theoretical basis for the prevention and treatment of AMI in the future. Methods The suspected AMI patients of the first affiliated hospital of Soochow university in 2018 year were selected as the research object. The clinical data of patients and the detection results of high-sensitivity troponin T (hs-cTnT) were analyzed retrospectively by using Excel database and SPSS statistical software, so as to further clarify the characteristics of clinical population distribution, the peak period of treatment and the clinical application value of hs-cTnT. Results A total of 13 709 patients were admitted to the outpatient and emergency department for treatment mainly due to self-induced chest pain, chest tightness, palpitations, dyspnea and other discomfort. A total of 3 585 cases (26.15%) with suspected AMI were detected, including 2 170 (60.53%) males and 1 415 (39.47%) females. The ratio of male to female was 1.5∶1. The age ranged from 11 to 100 years old, and the median age was 72 years old, and there were significant differences among all age groups (all P<0.05). Among them, 279 (7.78%) cases were young people (<40 years old). In the 3 306 (92.22%) middle-aged and elderly (>41 years old) cases, especially 2 757 (76.90%) >61 years old cases, there was statistically significant (P<0.05). The seasonal detection was statistically significant (P<0.05), mainly in winter (especially 1-2 months) and spring (3-5 months). The overall detection rate of male patients was always higher than that of female patients. The hs-cTnT level of the patients increased with age, and the level of male patients in the same age group was higher than that of female patients, and the hs-cTnT detection line of male patients (≥51 years old) and female patients (≥61 years old) was higher than the baseline level of the overall population. Conclusion The detection rate of suspected AMI in our hospital is relatively high, mainly in the middle-aged and elderly people, and the intensity and scope of seasonal hs-cTnT screening should be strengthened in high-risk groups with chest pain, palpitations and other self-conscious symptoms.
