摘要:
目的 建立零膨胀联合脆弱模型探讨冠状动脉粥样硬化性心脏病(简称冠心病)合并慢性心力衰竭患者不同结局的影响因素,降低患者不良结局的发生。 方法 选取2014-2015年两所三级甲等医院冠心病合并慢性心力衰竭患者,收集患者住院期间的电子病历信息以及随访信息,建立零膨胀联合脆弱模型进行影响因素分析。 结果 本研究共纳入患者2 221例,1 312例患者未发生任何事件(59.07%),699例患者再住院(31.47%),307例患者死亡(13.82%)。性别、职业、BMI是冠心病合并慢性心力衰竭患者不同结局的共同影响因素,陈旧性心肌梗死、QRS间期延长是减少患者未再住院的可能性的影响因素;高龄、美国纽约心脏病协会(New York heart association, NYHA)心功能分级≥Ⅲ级、心脏瓣膜病是患者再住院与死亡的危险因素,增加再住院与死亡风险;QRS间期延长和心房颤动是患者死亡的危险因素,冠脉搭桥为保护性因素,降低患者死亡风险。 结论 零膨胀联合脆弱模型可同时分析冠心病合并慢性心力衰竭患者未再住院、再住院及死亡的影响因素,为高危患者识别、干预和治疗提供理论依据。 Abstract:Objective Joint frailty models for zero-inflated was established to explore the influential factors of different outcomes for patients with coronary heart disease complicated with chronic heart failure to reduce the incidence of adverse outcomes. Methods The sample includes patients with coronary heart disease complicated with chronic heart failure in two tertiary hospitals of Shanxi Province from 2014 to 2015. The electronic medical record information of patients during hospitalization and their follow-up information were collected, and joint frailty models for zero-inflated was established to analyze the influential factors. Results A total of 2 221 patients were included in this study. 1 312 patients had no incident (59.07%), 669 patients were re-hospitalized (31.47%) and 307 patients died (13.82%). Gender, occupation and BMI were common influential factors for different outcomes of patients with coronary heart disease complicated with chronic heart failure. Old myocardial infarction and prolonged QRS interval were influential factors to reduce the possibility of patients not being hospitalized again. Advanced age, NYHA grade ≥ Ⅲ and valvular disease were risk factors for rehospitalization and death. Prolonged QRS interval was a risk factor of death; on the contrary, coronary artery bypass grafting was a protective factor to reduce mortality. Conclusions Joint frailty models for zero-inflated can analyze the influential factors of non-rehospitalization, rehospitalization and death for patients with coronary heart disease complicated with chronic heart failure simultaneously, and provide a theoretical reference for the identification, intervention and treatment of high-risk patients. -
