【摘要】 目的 探讨2型糖尿病（T2DM）胰岛素抵抗导致糖尿病性心功能不全的临床表现特点及相关激素的改变。 方法 2008年1-4月对T2DM患者35例（胰岛素抵抗指数HOMA-IRlt;2.69者19例为A1组，HOMA-IR≥2.69者16例为A2组）及健康体检者20人B组测体重指数（BMI）、空腹血糖（FPG）、胰岛素、心钠素（ANP）、脑钠素（BNP）水平；心脏彩色多普勒超声分别测E/A、e/a、S/D、LVEF、DT期。 结果 A2组BMI较A1、B组均明显增加（Plt;0.05），A1、B组间差异无统计学意义（Pgt;0.05）。ANP、BNP及DT值在A1、A2组均较B组增高（Plt;0.05），BNP在A2组高于A1组（Plt;0.05），ANP、DT值在A1、A2组间差异均无统计学意义（Pgt;0.05）。E/A、e/a和S/D在A1、A2组均较B组降低（Plt;0.05），A1、A2组间差异均无统计学意义（Pgt;0.05）。A2组患者LVEF较A1、B组均明显降低（Plt;0.05），A1、B组间差异无统计学意义（Pgt;0.05）。 结论 随着胰岛素抵抗加重，心肌舒张顺应性较差和收缩力下降，伴随相关激素（心脏利钠肽）分泌增加，最终产生心功能不全的临床表现、体征及多普勒超声心动图表现。【Abstract】 Objective To investigate the clinical features and related hormone changes of diabetic cardiac insufficiency leaded by insulin resistance in type 2 diabetes mellitus (T2DM). Methods From January to April 2008, 35 patients with T2DM (group A1: HOMA-IRlt;2.69, n=19; group A2: HOMA-IR≥ 2.69, n=16) and 20 subjects without T2DM (group B) were enrolled. The body mass index (BMI), fasting plasma glucose (FPG), insulin (FINS), atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and E/A, e/a, S/D, LVEF and DT stage of all subjects were detected. Results The BMI in group A2 was higher than those in group A1 and group B (Plt;0.05), while the difference between the later two groups was not statistically significant (Pgt;0.05). The ANP, BNP and DT stage were all higher than those in group B (Plt;0.05), the BNP was higher in group A2 than in group A1 (Plt;0.05), while the difference of neither ANP nor DT stage between the later two groups was statistically significant (Pgt;0.05). The values of E/A, e/a and S/D in group A1 and A2 were all lower than those in group B (Plt;0.05), while there were no statistically significant diferences between group A1 and A2 (Pgt;0.05). The values of LVEF of group A1 and A2 were both significantly reduced than that in group B (Plt;0.05), and the values in group A2 were the lowest (Plt;0.05). Conclusion With the aggravating of insulin resistance, myocardial contractility and diastolic function will decline, meanwhile the ANP and BNP secretion will increase, and then the clinical and echocardiographic manifestation will appear.

Objective To compare the clinical efficacy and safety of thrombolysis with anticoagulation therapy for patients with acute sub-massive pulmonary thromboembolism. Methods The clinical data of 84 patients with acute sub-massive pulmonary thromboembolism were analyzed retrospectively, mainly focusing on the in-hospital efficacy and safety of thrombolysis and/ or anticoagulation. The efficacy was evaluated based on 6 grades: cured, markedly improved, improved, not changed, deteriorated and died. Results Among the 84 patients,49 patients received thrombolysis and sequential anticoagulation therapy( thrombolysis group) , 35 patients received anticoagulation therapy alone( anticoagulation group) . As compared with the anticoagulation group, the thrombolysis group had higher effective rate( defined as patients who were cured, markedly improved or improved, 81. 6% versus 54. 3%, P = 0. 007) , lower critical event occurrence ( defined as clinical condition deteriorated or died, 2. 0% versus 14. 3% , P = 0. 032) . There was no significant difference in bleeding rates between the two groups ( thrombolysis group 20. 4% versus anticoagulation group 14. 3% , P gt; 0. 05) . No major bleeding or intracranial hemorrhage occurred in any of the patients. Conclusions Thrombolysis therapy may be more effective than anticoagulation therapy alone in patients with acute sub-massive pulmonary thromboembolism, and thus warrants further prospective randomized control study in large population.
Objective To analyze the clinical features of patients with acute pulmonary embolism ( APE) with normal blood pressure and right ventricular dysfunction. Methods 130 hospitalized patients with normotensive APE between January 2009 and January 2012 were retrospectively analyzed. The patients underwent transthoracic echocardiography to determine if they were complicated with RVD. The clinical features, risk factors, diagnosis, and treatment were analyzed and compared between the normotensive APE patients with or without RVD. Results 41 normotensive APE patients with RVD were as RVD group, and other 89 patients without RVD were as non-RVD group. The incidences of syncope ( 34.1% vs. 7.8% ) , tachycardia( 41.4% vs. 21.3% ) , P2 hyperthyroidism( 46.3% vs. 25.8% ) , jugular vein filling ( 12.1% vs. 1.1% ) , and cyanosis ( 26.8% vs. 8.9% ) were all significantly higher in the RVD group than those in the non-RVD group ( P lt; 0.05) . Computed tomography pulmonary angiography ( CTPA) revealed that the incidences of thromboembolism involving proximal pulmonary artery ( 58. 3% vs. 8. 3% ) and thromboembolism involving lobar pulmonary ( 77.8% vs.51.2% ) were also higher in the RVD group ( P lt; 0.001, P = 0.025 ) . In the RVD group, the patients were assigned to received thrombolysis plus anticoagulation therapy, or anticoagulation therapy alone. The clinical indicators ( heart rate, PaCO2 , AaDO2 , SPAP, TRPG) were all statistically improved after thrombolysis or anticoagulation treatment ( P lt;0.001) . But compared with the patients who underwent anticoagulation therapy alone, the cost of treatment and the incidence of minor bleeding were significantly higher, and the levels of AaDO2 , SPAP and TRPG were statistically lower in the patients with thrombolysis plus anticoagulation therapy. Conclusions For APE patients with central pulmonary embolism demonstrated by CTPA, syncope, and tachycardia, transthoracic echocardiograph should be performed as early as possible to confirm RVD diagnosis. For normotensive APE patients with RVD, anticoagulant treatment can achieve higher efficacy of costeffectiveness ratio.
Objective To investigate clinical outcomes of one and a half ventricle repair for acute right ventricular dysfunction after biventricular repair. Methods Clinical data of 5 pediatric patients with congenital heart diseases who underwent emergency bidirectional Glenn shunt without cardiopulmonary bypass for acute right ventricular dysfunction after biventricular repair，converting the operation into one and a half ventricle repair，from February 2007 to June 2012 in Qingdao Women and Children Hospital were retrospectively analyzed. There were 4 male patients and 1 female patient with their age of 7-18 months and body weight of 6-13 kg. Preoperative diagnosis included pulmonary atresia with intact ventricular septum （PA/IVS） in 1 patient，tricuspid stenosis （TS） with ventricular septal defect （VSD） and atrial septal defect （ASD） in 2 patients，and tricuspid stenosis with tetralogy of Fallot （TOF） in 2 patients. Postoperative care focused on cardiopulmonary support and control of pulmonary artery pressure. Results Mean pulmonary artery pressure （mPAP） was 12-18 mm Hg at 72 hours after emergency bidirectional Glenn shunt. Mechanical ventilation time was 3-182 hours and ICU stay was 2-13 days. Postoperatively 1 patient died of pulmonary hypertension crisis. The other 4 patients were discharged with their transcutaneous oxygen saturation in the resting state of 93%-99%，which was improved in different degrees compared with preoperative value. These 4 patients were followed up from 6 months to 4 years. Three patients were in NYHA classⅠand 1 patient was in NYHA class Ⅱ during follow-up. Echocardiography showed smooth vena cava to pulmonary artery anastomosis without thrombosis formation. Conclusion One and a half ventricle repair can be used as an adjunct surgical strategy for acute right ventricular dysfunction after biventricular repair.
Abstract： Right ventricular dysfunction or right heart failure is a complex clinical syndrome and often leads to a poor prognosis and high mortality. In order to detect right ventricular dysfunction at an early stage, provide a therapy guidance and evaluate treatment outcomes， right ventricular function evaluation has aroused more and more concern in clinical physicians. With the advantages of being non-invasive， accuracy and repetitiveness， echocardiography is used extensively in the assessment of heart function. In this review， we focus on how to use echocardiography to evaluate right ventricular function easily, efficiently， accurately and sensitively， and provide a good foundation for its further clinical application.
