  • Effects of levosimendan on patients undergoing valve replacement

    ObjectiveTo investigate the effect of postoperative use of levosimendan on patients with valve replacement.MethodPatients with valvular diseases who underwent valve replacement were prospectively enrolled during Jan 2014 to May 2018 in Qingdao Municipal Hospital, randomized to a levosimendan-treated group (n=93) and a control group (n=92) preoperatively. Patients in both groups underwent the same routine treatment preoperatively and postoperatively. In addition, patients in the levosimendan-treated group underwent levosimendan intravenous infusion 24 hours after entering ICU postoperatively. The clinical effect of the two groups was compared.ResultsCompared to the control group, the cardiac output(CO, 5.2±1.0 L/min vs. 4.4±1.1 L/min on the seventh day after surgery) and left ventricular ejection fraction (LVEF, 55.7%±2.5% vs. 50.5%±2.2% on the seventh day after surgery) of levosimendan-treated group were increased significantly at different time points(1 day, 3 days and 7 days after surgery)(P<0.05), and the brain natriuetic peptid (BNP) level (312.5±34.6 pg/ml vs. 455.4±45.2 pg/ml on the seventh day after surgery) was less than that of the control group (P<0.05). The dosage (11.5±1.8 mg/kg vs. 20.4±2.1 mg/kg) and administration time of vasoactive agents in the levosimendan-treated group were significantly lower or shorter than those in the control group (70.4±11.2 h vs. 110.5±12.1 h, P<0.05). The ICU stay length, and the total incidence of adverse events were less than those of the control group (P<0.05).ConclusionPostoperative use of levosimendan immediately after surgery can significantly improve the cardiac function status of patients who underwent valve replacement, reduce the dosage of vasoactive agents, shorten the time of ICU hospitalization, reduce the incidence of adverse events and enhance the patient’s recovery after valve replacement.

  • “一站式”杂交技术在冠状动脉多支血管病变中的临床应用

    目的探讨“一站式”杂交技术治疗冠状动脉多支血管病变的安全性及治疗效果。方法回顾性分析我院 2018 年 8 月至 2019 年 8 月行“一站式”杂交技术冠状动脉血运重建 22 例冠状动脉多支血管病变患者的临床资料,其中男 16 例、女 6 例,平均年龄 50~81(60.5±8.2)岁。患者在杂交手术室先完成经左胸小切口冠状动脉旁路移植术,之后行冠状动脉介入治疗术。回顾性分析患者围术期资料,并进行随访,采用 SF-36 量表评估患者术后 3 个月生活质量以及观察随访期间主要不良心脑血管事件(MACCE)发生情况。结果该组患者围术期无死亡病例,住院期间无严重并发症发生。随访 3 个月至1 年,随访期间 1 例患者发生脑卒中,无其它 MACCE 发生,生活质量明显改善。结论“一站式”杂交冠状动脉血运重建治疗冠状动脉多支血管病变安全有效,近期疗效满意。

  • Hybrid coronary revascularization versus off-pump coronary artery bypass grafting for treatment of multivessel coronary artery diseases

    ObjectiveTo investigate the feasibility and safety of hybrid coronary revascularization (HCR) in patients with multivessel coronary artery disease (MVCAD).MethodsA total of 50 patients with MVCAD who underwent HCR technique in our heart center from May 2016 to April 2019 were included in this study (a HCR group), including 38 patients who underwent two-stage HCR and 12 patients one-stop HCR. There were 39 males and 11 females, with an average age of 62.4 (46-82) years. Another 482 patients who underwent conventional median incision under off-pump coronary artery bypass grafting (OPCAB) at the same period were selected as control (an OPCAB group), including 392 males and 90 females, with an average age of 64.2 (48-84) years. The safety and feasibility of HCR were evaluated and compared with conventional OPCAB technique.ResultsThere was no perioperative death in both groups. Compared with the OPCAB, HCR was associated with shorter operation time, less chest tube drainage, lower requirement of blood transfusion, shorter mechanical ventilation time and shorter postoperative intensive care unit (ICU) stay (P<0.05). There was no statistical difference in the incidence of major adverse cardiac or cerebrovascular events during the follow-up of 6 to 36 months between the two groups.ConclusionHCR provides favorable short and mid-term outcomes for selected patients with MVCAD compared with conventional OPCAB.

  • Incidence of postoperative acute kidney injury and risk factors for prognosis in patients with acute Stanford type A aortic dissection

    ObjectiveTo investigate the prognosis and impact of postoperative acute kidney injury (AKI) on patients with acute Stanford type A aortic dissection (ATAAD), and to analyze the predictors for short- and medium-term survival. MethodsClinical data of patients who underwent ATAAD surgery in Qingdao Municipal Hospital from May 2014 to May 2019 were retrospectively analyzed. All discharged patients underwent telephone or outpatient follow-up, and were divided into an AKI group and a non-AKI group based on whether AKI occurred after surgery. The impact of postoperative AKI on the short- and medium-term prognosis was analyzed, and multivariate Cox analysis was used to screen the risk factors for short- and medium-term mortality. ResultsA total of 192 patients were collected, including 139 males and 53 females, with an average age of 53.3±11.4 years. Postoperative AKI was identified in 43 (22.4%) patients. The average follow-up time of discharged patients was 23.4±2.4 months, and the lost rate was 5.1%. The two-year survival rate after discharge of the AKI group was 88.2%, and that of the non-AKI group was 97.2%. Kaplan-Meier survival analysis and log-rank test showed that there was a statistical difference between the two groups (χ2=5.355, log-rank P=0.021). Multivariate Cox analysis results showed that age (HR=1.070, 95%CI 1.026 to 1.116, P=0.002), cardiopulmonary bypass time (HR=1.026, 95%CI 1.003 to 1.050, P=0.026), postoperative AKI (HR=3.681, 95%CI 1.579 to 8.582, P=0.003), transfusion volume of red blood cell intraoperatively and within 24 hours postoperatively (HR=1.548, 95%CI 1.183 to 2.026, P=0.001) were independent risk factors for the short- and medium-term mortality of ATAAD patients. ConclusionThe incidence of postoperative AKI is high in ATAAD patients, and the mortality of patients with AKI increases significantly within two years. Age, cardiopulmonary bypass time and transfusion volume of red blood cell intraoperatively and within 24 hours postoperatively are also independent risk factors for short- and medium-term prognosis.
