目的 观察利伐沙班对心力衰竭（HF）合并心房颤动（AF）患者凝血因子及预后情况的影响。方法 采用前瞻性研究,纳入平顶山市第二人民医院2021年1月—2022年4月期间收治的123例HF合并AF患者,以数字随机表法将入组患者分为常规组（61例）和试验组（62）例,两组均行起搏器植入术（CRTD）治疗,常规组予以常规抗凝治疗辅助CRTD,试验组予以利伐沙班辅助CRTD,所有患者术后均开展一年随访,比较两组患者治疗前后的抗Xa凝血因子、心肌损伤标志物、心功能指标变化情况,以及术后血栓栓塞、心血管死亡事件发生情况。结果 治疗前,两组患者的Xa凝血因子,心肌损伤标志物,心功能指标比较差异无统计学意义（P>0.05）;在不同抗凝方案下,观察组治疗1 d后的抗Xa凝血因子为（130.44±20.18）IU/mg,治疗3 d后的抗Xa凝血因子为（115.36±20.77）IU/mg,治疗7 d的抗Xa凝血因子为（90.25±20.44）IU/mg,均低于常规组[（145.33±20.19）IU/mg、（128.45±20.16）IU/mg、（103.34±20.17）IU/mg],差异有统计学意义（P<0.05）。治疗后,试验组的肌酸激酶同工酶为（7.52±2.16）U/L,心肌肌钙蛋白Ⅰ为（0.52±0.12）ng/mL,乳酸脱氢酶为（126.41±20.45）U/L,均低于常规组[（8.44±2.28）U/L、（0.94±0.31）ng/mL、（140.33±20.25）U/L],差异有统计学意义（P<0.05）。治疗后,观察组的左室射血分数为（56.12±10.41）%,高于常规组（50.24±10.33）%,左室舒张末期内径为（47.11±10.25）mm,左室舒张末期容积为（36.72±10.43）mL,均低于常规组（53.28±10.14）mm、（42.77±10.36）mL,差异有统计学意义（P<0.05）。随访期间,试验组的血栓栓塞事件发生率为4.84%（3/62）,心血管死亡事件发生率为3.23%（2/62）,均低于常规组[19.67%（12/61）、14.75%（9/61）],差异有统计学意义（P<0.05）。结论 利伐沙班辅助CRTD能有效增强HF合并AF患者的抗Xa凝血因子活性,对减轻心肌损伤、改善心功能并降低血栓栓塞或心血管死亡风险均有积极意义。

Objective To observe the effect of rivaroxaban on coagulation factors and prognosis in patients of heart failure（HF）with atrial fibrillation（AF）．Methods This is a prospective study．The patients were included from January 2021 to April 2022 in Pingdingshan Second People’s Hospital．The study subjects were 123 patients with HF and AF．The enrolled patients were divided into the conventional group（61 cases）and the experimental group（62 cases）by the method of digital random table．Both groups were treated with cardiac resynchronization therapy with defibrillator（CRTD）．The conventional group was treated with conventional anticoagulation therapy to assist CRTD,and the experimental group was treated with rivaroxaban to assist CRTD．All patients were followed up for one year after surgery,the changes in anti-Xa coagulation factors,myocardial injury markers,cardiac function indicators,as well as the incidence of postoperative thromboembolism and cardiovascular death events between the two groups of patients before and after treatment were compared．Results Before treatment,there were no statistically significant differences in Xa coagulation factor,myocardial injury markers and cardiac function indicators between the two groups of patients（P>0.05）．Under different anticoagulation regimens,the anti-Xa coagulation factor levels in the observation group were（130.44±20.18）IU/mg after 1 day of treatment,（115.36±20.77）IU/mg after 3 days of treatment,and（90.25±20.44）IU/mg after 7 days of treatment,which were lower than that in the conventional group [（145.33±20.19）IU/mg,（128.45±20.16）IU/mg,（103.34±20.17）IU/mg]（P<0.05）．After treatment,the CK-MB level of the experimental group was（7.52±2.16）U/L,cTnI was（0.52±0.12）ng/mL,and LDH was（126.41±20.45）U/L,which were lower than that of the conventional group [（8.44±2.28）U/L,（0.94±0.31）ng/mL,（140.33±20.25）U/L]（P<0.05）．After treatment,the left ventricular ejection fraction of the observation group was（56.12±10.41）%,which was higher than the conventional group（50.24±10.33）%,left ventricular diameter was（47.11±10.25）mm,left ventricular end disastolic volume was（36.72±10.43）mL,which were lower than the conventional group（53.28±10.14）mm,（42.77±10.36）mL（P<0.05）．During the follow-up period,the incidence of thromboembolism events in the experimental group was 4.84%（3/62）,and the incidence of cardiovascular death events was 3.23%（2/62）,which was lower than the conventional group [19.67%（12/61）,14.75%（9/61）]（P<0.05）．Conclusions Rivaroxaban assisted CRTD can effectively enhance the activity of anti-Xa coagulation factors in patients with HF and AF,which has positive significance in reducing myocardial injury,improving cardiac function and reducing the risk of thromboembolism or cardiovascular death．

目的 探讨急性脑出血并发高钠血症的原因及预后情况。方法 选择2017年1月—2018年8月就诊于我院的急性脑出血并发高钠血症60例为观察组[根据血清钠离子浓度分为重度组37例（血清钠离子浓度>170 mmol/L）,中度组12例（钠离子浓度161~170 mmol/L）,轻度组11例（钠离子浓度145~160 mmol/L）],选择同期就诊于我院不伴高钠血症的脑出血患者60例为对照组。比较两组意识障碍程度、出血部位、死亡率,并分析急性脑出血并发高钠血症患者中不同血清钠离子浓度患者预后情况。结果 观察组GCS评分≤8分比例、丘脑出血比例、死亡率高于对照组,差异有统计学意义（P<0.05）;观察组基底节区、脑干小脑、脑叶出血比例与对照组比较,差异无统计学意义（P>0.05）;血清钠离子浓度越高则患者的预后越差,差异有统计学意义（P<0.05）。结论 与急性脑出血患者相比,急性脑出血患者并发高钠血症患者的死亡率较高,且预后情况与血清钠离子浓度密切相关;丘脑部出血与急性脑出血患者并发高钠血症密切相关,临床应加以重视。
