摘要:
目的:系统分析2019—2024年天津市某三级甲等医院住院急性心肌梗死(AMI)患者院内病死率的变化趋势及其影响因素。方法:采用回顾性队列研究,纳入天津市第一中心医院2019年1月1日至2024年12月31日收治的7897例确诊AMI住院患者。利用SPSS27.0软件,对年龄、性别、季节、AMI亚型、合并症、实验室指标及经皮冠状动脉介入治疗(PCI)与院内死亡的关系进行单因素及多因素Logistic回归分析。结果:2019—2024年AMI住院患者粗病死率介于5.28%~8.79%,呈先波动后显著下降趋势(趋势χ2=11.468,P<0.001),6年平均粗病死率为7.21%(569/7897),6年平均标化病死率为2.47%,年度标化病死率由2019年的3.74%降至2024年的1.94%。秋冬季病死率显著高于春夏季(P<0.05)。患者年龄中位数为66岁,发病高峰集中于60~69岁年龄组,病死率随年龄增加持续升高,≥80岁年龄组最高(χ2=11.559,P<0.05)。男性5501例(69.7%),女性2396例(30.3%);男性粗病死率显著低于女性(5.96%vs.10.0%,χ2=41.878,P<0.001)。ST段抬高型心肌梗死(STEMI)组4339例(54.9%),非ST段抬高型心肌梗死(NSTEMI)组3484例(44.1%),STEMI组病死率高于NSTEMI组(8.02%vs.6.31%,χ2=8.350,P<0.05)。多因素Logistic结果表明,年龄增加、Killip心功能Ⅲ/Ⅳ级、凝血酶原时间、白细胞计数水平升高、嗜酸性粒细胞计数低于正常组(以正常组为参考),为AMI院内死亡的独立危险因素(均P<0.05)。PCI手术、脂肪肝、Killip心功能Ⅰ/Ⅱ级、血小板减少与死亡呈负相关(均P<0.05)。PCI治疗组病死率为2.04%(73/3574),显著低于未PCI组的14.80%(624/4223,χ2=463.126,P<0.001),其获益在男性(98.45%,3440/3494)及50~59岁年龄组(99.1%,1045/1054)尤为突出。结论:2019—2024年天津某三甲医院住院AMI患者标化病死率总体呈显著下降趋势,死亡风险仍受年龄、AMI亚型、心功能状态、炎症、凝血功能及合并症等多因素共同影响,PCI是改善预后的关键干预措施。
Abstract:
Objective: To systematically analyze trends and influencing factors in in-hospital case fatality rate among inpatients with acute myocardial infarction(AMI) admitted to a Grade A tertiary hospital in Tianjin from 2019 to 2024. Methods: A retrospective cohort study was adopted, and 7 897 inpatients diagnosed with AMI admitted to Tianjin First Central Hospital from January 1, 2019, to December 31, 2024, were enrolled. Using SPSS 27.0, univariate and multivariate Logistic regression analyses were performed to examine the relationships among age, gender, season, AMI subtypes, comorbidities, laboratory indicators, percutaneous coronary intervention(PCI), and in-hospital mortality. Results: From 2019 to 2024, the crude in-hospital case fatality rate for patients with AMI ranged from 5.28% to 8.79%, initially fluctuating and then declining sharply(trend χ2=11.468, P<0.001). Over six years, the average crude case fatality rate was 7.21%(569/7 897), while the average standardized case fatality rate was 2.47%; annually, stan-dardized case fatality rate dropped from 3.74% in 2019 to 1.94% in 2024. Case fatality rate was notably higher in autumn and winter than in spring and summer(P<0.05). Patients had a median age of 66, with peak AMI incidence concentrated in the age group of 60 and 69 years old. Case fatality rate climbed steadily with age, reaching its highest among those 80 and older (χ2=11.559, P<0.05).Of 7 897 patients, 5 501(69.7%) were male, and 2 396(30.3%) female; crude case fatality rate for males was 5.96%, notably lower than females at 10.0%(χ2=41.878, P<0.001). The ST segment elevation myocardial infarction(STEMI) group accounted for 4 339 cases(54.9%), the non ST segment elevation myocardial infarction(NSTEMI) group for 3 484(44.1%), with case fatality rate higher in STEAMI than NSTEAMI(8.02% vs. 6.31%, χ2=8.350, P<0.05). The results of multivariate Logistic regression identified increased age, Killip classⅢ/Ⅳ, longer prothrombin time, higher white blood cell counts, and lower eosinophil counts compared to the normal group as independent predictors for in-hospital mortality in AMI(all P<0.05). Conversely, PCI, fatty liver, Killip classⅠ/Ⅱ, and thrombocytopenia were negatively correlated with mortality(all P<0.05). PCI-treated patients had a 2.04% case fatality rate(73/3 574), far lower than 14.80%(624/4 223) in non-PCI patients(χ2=463.126, P<0.001), with benefits especially appar-ent for males(98.45%, 3 440/3 494) and those aged 50-59(99.1%, 1 045/1 054). Conclusion: From 2019 to 2024, the standar-dized case fatality rate among hospitalized AMI patients at a tertiary hospital in Tianjin showed a significant downward trend. Howev-er, mortality risk remained influenced by multiple factors, including age, AMI subtype, cardiac function, inflammation, coagulation status, and comorbidities. PCI is a key intervention for improving prognosis.
