  • 心脏不停跳手术中心肌NF-κB转录活性、ICAM-1的表达及其临床意义

    目的 探讨心脏不停跳与心脏停搏手术对心肌核转录因子κB(NF-κB)转录活性、细胞间黏附分子-1(ICAM-1)表达水平的影响及其临床意义。方法 将40例先天性心脏病患者随机分为两组,每组20例。组Ⅰ:行心脏不停跳心内直视手术;组Ⅱ:行常规体外循环手术(灌注冷晶体心脏停搏液)。两组患者均于心内操作前、后取右心房壁心肌组织检测NF-κB转录活性、ICAM-1表达水平,用透射电子显微镜观察心肌超微结构;分别于术前、主动脉开放或心内操作完成后1、24、48和72h测定两组心肌肌钙蛋白I(cTnI)、肌酸激酶同工酶MB(CK-MB),并对其结果进行比较。结果术后组Ⅰ NF-κB转录活性、ICAM-1表达水平较术前无显著变化,组Ⅱ NF-κB转录活性较术前升高(Plt;0.01);术后NF-κB转录活性组Ⅱ显著高于组Ⅰ(Plt;0.01)。术后两组血清cTnI、CK-MB水平较术前均有不同程度升高(Plt;0.01),主动脉开放后/心内操作完成后各时点,组Ⅱ均显著高于组Ⅰ(Plt;0.01)。透射电子显微镜观察,组Ⅰ术后心肌超微结构无明显变化,组Ⅱ心肌损伤变化显著。结论 心脏不停跳下心内直视手术术后短期内心肌NF-κB转录活性、ICAM-1表达水平无明显变化,减轻了心肌缺血-再灌注损伤及由NF-κB激活而引起的心肌炎性反应,有较好的心肌保护效果。

  • 心脏不停跳与冷晶体停搏在常见先心病矫治术中对肌钙蛋白I的影响

    目的 探讨常见先天性心脏病矫治术中心脏不停跳与心脏停搏两种术式对心肌肌钙蛋白 I(c Tn I)的影响及其心肌保护的效果。 方法  36例先天性心脏病矫治术患者按入院顺序以奇偶数随机分为心脏不停跳组 (组II)和冷晶体停搏组 (组I)两组 ,每组 18例。分别于术前、主动脉开放后 (组 为缝合右心房壁后 ) 1、2 4、4 8、72和 96 h取患者中心静脉血 ,测定 c Tn I、肌酸激酶 (CK)、肌酸激酶同工酶 (CK- MB)、乳酸脱氢酶 (L DH) ,并用透射电子显微镜观察两组各前 10例患者心内操作前、后心肌超微结构。 结果 两组术后血清 c Tn I、CK、CK- MB和 L DH水平均不同程度升高。两组 c Tn I均于术后 1h达峰值 ,主动脉开放后各时点组II显著高于组I(t=- 32 3.0 4 ,Plt;0 .0 1) ;组ICK-MB术后 2 4 h达峰值 ,组II术后 1h达峰值 ,主动脉开放后各时点组II显著高于组I(t=- 72 .5 3,Plt;0 .0 1) ;CK、L DH变化趋势与 CK- MB相似。组I术后心肌超微结构变化轻微 ,组II明显改变 ,...更多其受损程度分级较术前重。 结论 常见先天性心脏病矫治术中心脏不停跳可明显减轻心肌缺血、缺氧及再灌注损伤 ,减少 c Tn I的释放 ,较冷晶体停搏术有良好的心肌保护效果。

  • Comparison of different anticoagulation methods during perioperative period for non-cardiac surgery in patients after cardiac valve replacement

    ObjectiveTo summarize the efficacy of different anticoagulation methods during perioperative period of non-cardiac surgery after cardiac valve replacement and to compare the postoperative bleeding-related complications and embolization-related complications.MethodsRetrospective analysis of clinical data of 56 patients who underwent non-cardiac surgery after cardiac valve replacement in our hospital from January 2016 to January 2018 was conducted. There were 27 males and 29 females, aged 19-75 (53.56±13.94) years. According to different anticoagulation methods during perioperative period, the patients were divided into a bridging group (32 patients) and a non-bridging group (24 patients). The postoperative hospital stay, the number of patients needing postoperative blood transfusions, bleeding-related complications and embolization-related complications were compared between the two groups. According to the patient’s perioperative embolization risk, each group of patients were divided into a high-risk subgroup, middle-risk subgroup, and low-risk subgroup, and the bleeding-related complications and embolization-related complications in each subgroup were compared.ResultsThe postoperative hospital stay in the bridging group was significantly longer than that in the non-bridging group (P<0.05), but there was no significant difference in the number of patients needing postoperative blood transfusions, overall bleeding-related complications and embolization-related complications between the two groups (P>0.05). Subgroup analysis was performed according to the degree of embolization risk in the perioperative period. The incidence of bleeding-related complications of the non-bridging group in the high-risk subgroup was significantly higher than that in the high-risk subgroup of the bridging group (P<0.05). The incidence of bleeding-related complications in the bridging group was similar to that of embolization-related complications, while the rate of bleeding-related complications in the non-bridging group was 7 times higher than that of embolization-related complications.ConclusionBridging anticoagulation increases the length of postoperative hospital stay, but for patients with high risk factors for embolization, it is more beneficial than continuing oral warfarin during the perioperative period. The incidence of bleeding-related complications associated with continued warfarin therapy is significantly higher than that of embolization-related complications, and hemostatic drugs can be given necessarily.

  • Progress in surgical selection of aortic root diseases

    Total root replacement (TRR) with a valved conduit has long been the treatment standard for most aortic root diseases. However, with advances in technology and a deeper understanding of aortic root anatomy and hemodynamics, valve-sparing aortic root replacement (VSRR) and personalised external aortic root support (PEARS) have emerged. It is especially important to choose the appropriate procedure for different aortic root diseases. When evaluating these three surgical procedures, it is necessary to focus on the treatment and prevention of the dissection and balance the short-term and long-term risks of the patients. This article outlines aortic-related diseases and the selection of surgery.

  • Progress in surgical treatment of aortic regurgitation caused by Takayasu arteritis

    Takayasu arteritis (TA) is a primary, chronic, non-specific, inflammatory disease of the aorta and its larger branches. The pulmonary artery trunk and its branches could be impacted by TA, which could cause stenosis or occlusion of lesion vessels. TA also affects the normal function of the aortic valve and other heart valves, mainly due to valvular insufficiency. Aortic regurgitation caused by TA is mainly treated by surgical operation. In this review, the examination technique, operation timing, operation method and prognosis of aortic valve involved in TA are discussed systematically.

  • Research progress of anxiety and depression in adult patients undergoing cardiac surgery

    Anxiety is a strong behavioral and psychological reaction with fear components, while depression is a mental disorder dominated by high or low mood, both of which are accompanied by cognitive and behavioral changes, and are common comorbidities in patients with heart disease. Cardiac surgery is one of the important factors which trigger specific emotional and physiological reactions of patients. Persistent or initial depression and anxiety after surgery will not only increase surgical complications, short- or long-term mortality and medical costs, but also seriously affect patients' social function and quality of life. With the transformation of bio-psycho-social medical model, it is necessary to evaluate the perioperative psychological state and biological risk of patients undergoing cardiac surgery. This article reviews the characteristics, related mechanisms and therapeutic interventions of anxiety and depression in patients undergoing cardiac surgery.
