Risk factors and postoperative complications can worsen the condition of patients undergoing coronary artery bypass grafting; some of these factors and complications are closely related to mortality rate.
To describe clinical factors and outcomes related to mortality of patients undergoing coronary artery bypass grafting and on invasive mechanical ventilation.
This is a single-center retrospective data analysis of patients who underwent coronary artery bypass grafting on invasive mechanical ventilation between 2013 and 2019. Data regarding clinical characteristics, postoperative complications, intensive care unit and mechanical ventilation time, and their relationship with mortality were analyzed.
Four hundred seventy-two patients who underwent coronary artery bypass grafting entered the study. Their mean age was 62.3 years, and mean body mass index was 27.3. The mortality rate was 4%. Fifty percent of the patients who had ventilator-associated pneumonia died. Considering the patients who underwent hemotherapy and hemodialysis, 20% and 33% died, respectively. Days of intensive care unit stay and high Acute Physiology and Chronic Health Evaluation score and Simplified Acute Physiology Score were significantly related to death.
Factors and clinical conditions such as the patients' age, associated comorbidities, the occurrence of ventilator-associated pneumonia, length of stay in the intensive care unit, and mechanical ventilation time are related to higher mortality in patients undergoing coronary artery bypass grafting.
风险因素和术后并发症会使接受冠状动脉旁路移植术的患者病情恶化；其中一些因素和并发症与死亡率密切相关。
描述与接受冠状动脉旁路移植术和有创机械通气的患者死亡率相关的临床因素和结果。
这是一项对 2013 年至 2019 年间接受有创机械通气的冠状动脉旁路移植术患者进行的单中心回顾性数据分析。分析了与死亡率相关的临床特征、术后并发症、重症监护病房和机械通气时间及其关系的数据。
472 名接受冠状动脉旁路移植术的患者进入研究。他们的平均年龄为 62.3 岁，平均体重指数为 27.3。死亡率为 4%。50%患有呼吸机相关性肺炎的患者死亡。考虑到接受血液治疗和血液透析的患者，死亡率分别为 20%和 33%。重症监护病房住院天数、高急性生理学和慢性健康评估评分和简化急性生理学评分与死亡显著相关。
患者年龄、合并症、呼吸机相关性肺炎的发生、重症监护病房住院时间和机械通气时间等因素和临床情况与接受冠状动脉旁路移植术的患者死亡率较高有关。
