        • Effects of Recombinant Human Brain Natriuretic Peptide on Chinese Patients with Heart Failure: A Meta-analysis

          Objective To evaluate the efficacy of recombinant human brain natriuretic peptide (rhBNP) on Chinese patients with congestive heart failure by meta analysis. Methods Both foreign language databases including PubMed, EMbase, The Cochrane Library (Issue 3, 2009) and Chinese databases involving CBM, VIP and CJFD were searched to identify randomized controlled trials (RCTs) that reported the effect of rhBNP on the heart function (left ventricular ejection fraction (LVEF) and the recent level of improvement in cardiac function) and its side effects of Chinese patients with congestive heart failure. Two reviewers assessed the quality of each trial and extracted data independently. The Cochrane Collaboration’s RevMan 4.2.8 software was used for statistical analysis. Results Nineteen RCTs were included, all of which came from internal. The methodological quality of the included studies was good. The baseline data of each trial were comparable. The results of meta-analyses showed: (1) the improvement of LVEF was higher in the rhBNP group than that in the blank control group (WMD=7.22, 95%CI 3.15 to 11.291, P=0.000 5). The level of improvement in cardiac function was better in the rhBNP group than those in the blank control group (OR=5.48, 95%CI 1.61 to 18.65, P=0.007), the nitroglycerin group (OR=3.60, 95%CI 2.02 to 6.41, Plt;0.000 1), and the sodium nitroprusside group (OR=3.21, 95%CI 0.12 to 85.20, P=0.49). The incidence of side effects was lower in the rhBNP group than that in the nitroglycerin group (OR=0.23, 95%CI 0.11 to 0.47, Plt;0.000 1), and the sodium nitroprusside group (OR=0.30, 95%CI 0.11 to 0.82, P=0.02). Moreover, the results of sensitivity analysis were also consistent with the above findings. Conclusion Recombinant human brain natriuretic peptide can effectively improve the hemodynamics and cardiac function level of Chinese population of patients with heart failure. The treatment doses are safe and tolerant, so it is recommended to clinical use.

        • A comparative study on diagnostic indexes for right ventricular dysfunction in patients with acute pulmonary embolism

          Objective To explore and compare the diagnostic value of blood pressure, brain natriuretic peptide (BNP), pulmonary artery systolic pressure (PASP) in evaluating right ventricular dysfunction (RVD) in patients with acute pulmonary embolism (APE). Methods A retrospective study was conducted on 84 APE patients who were diagnosed by computed tomographic pulmonary angiography. The patients were divided into a RVD group and a non-RVD group by echocardiography. Eighteen clinical and auxiliary examination variables were used as the research factors and RVD as the related factor. The relationship between these research factors and RVD were evaluated by logistic regression model, the diagnostic value of BNP and PASP to predict RVD was analyzed by receiver-operating characteristic (ROC) curve analysis. Results The patients with RVD had more rapid heart rate, higher diastolic blood pressure, higher mean arterial pressure, higher incidence of BNP>100 pg/ml and higher incidence of PASP>40 mm Hg (allP<0 05="" upon="" logistic="" regression="" model="" bnp="">100 pg/ml (OR=4.904, 95%CI 1.431–16.806, P=0.011) and PASP>40 mm Hg (OR=6.415, 95%CI 1.509–27.261, P=0.012) were independent predictors of RVD. The areas under the ROC curve to predict RVD were 0.823 (95%CI 0.729–0.917) for BNP, and 0.798 (95%CI 0.700–0.896) for PASP. Conclusions Blood pressure related parameters can not serve as a predictor of RVD. Combined monitoring of BNP level and PASP is helpful for accurate prediction of RVD in patients with APE.

        • A systematic review of the effect of compound Danshen dripping pills combined with conventional Western medicine treatment on inflammatory factors and cardiac function after percutaneous coronary intervention for acute myocardial infarction

          ObjectiveTo systematically review the effect of compound Danshen dripping pills combined with Western medicine on inflammatory factors and cardiac function after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction.MethodsDatabases including CNKI, WanFang Data, VIP, CBM, PubMed, Web of Science, EMbase and The Cochrane Library were searched for randomized controlled trials of compound Danshen dripping pills combined with Western medicine in the treatment of acute myocardial infarction after PCI. The retrieval time was from the establishment of the databases to June 11th, 2020. Two reviewers independently screened literature, extracted data and evaluated the risk bias of included studies. RevMan 5.3 software was used for meta-analysis.ResultsA total of 16 studies were included, involving 2 069 patients. The results of the meta-analysis showed that the combination of compound Danshen dripping pills could increase the left ventricular ejection fraction (MD =?4.74, 95%CI 4.07 to 5.42, P<0.01), decrease the B-type natriuretic peptide (SMD=?3.81, 95%CI ?5.06 to ?2.57, P<0.01), the level of interleukin-6 (SMD=?3.20, 95%CI ?4.54 to ?1.86, P<0.01) and level of tumor necrosis factor-a (SMD=?4.96, 95%CI ?7.03 to ?2.89, P<0.01).ConclusionsCurrent evidence suggests that the combination of compound Danshen dropping pills has potential benefits in inhibiting inflammation and improving cardiac function after PCI. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.

        • Echocardiography in Evaluation of Right Ventricular Function

          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.

          Objective To discuss how is the perinatal infant’s prognosis influenced by different cardiac function and types of heart disease in pregnant women with heart disease, and to check the importance of antenatal examination. Method Retrospective analyses were conducted on the clinical records of 102 pregnant women hospitalized due to heart disease from February 2002 to February 2011 in the First Affiliated Hospital of Xinjiang Medical University. According to the level of cardiac function, 61 patients were divided into the Level I-II group and the other 41 patients were in the Level III-IV group. Results Of all cases, 38 were congenital heart disease (37.25%), followed by 22 arrhythmia (21.57%), 17 rheumatic heart disease (16.67%), 15 perinatal cardiomyopathy (14.71%), 7 hypertensive heart disease and 3 other types of heart disease. The average gestational weeks were shorter and the neonate’s weight was lower in the Level III-IV group than the Level I-II group, with a significant difference (Plt;0.05); the incidence of premature delivery, low birth weight infant at normal gestational age, neonatal asphyxia and perinatal mortality was higher in the Level III-IV group than the Level I-II group, with a significant difference (Plt;0.05); the rate of regular antenatal examination was higher in the Level III-IV group than the Level I-II group, with a significant difference (P=0.008); and there were significant differences between the regular and irregular examination groups in the incidence of premature delivery and low birth weight infant at normal gestational age (Plt;0.05), but no significant differences were found in the incidence of asphyxia and perinatal mortality (Pgt;0.05). Conclusions Congenital heart disease is the most commonly-seen type in the pregnant women with heart disease. The maternal cardiac function directly impact the prognosis of perinatal infant, and the regular antenatal examination, timely diagnosis and treatment can improve pregnancy outcome.

        • Perioperative changes of parathyroid hormone and cardiac function in patients with rheumatic heart disease

          ObjectiveTo investigate the perioperative change of parathyroid hormone (PTH) and its effect on cardiac function in patients with rheumatic heart disease.MethodsFrom January 2018 to June 2019, 76 patients were randomly divided into calcium supplement group (n=39) and control group (n=37). Mitral valve replacement was performed in both groups with cardiopulmonary bypass (CPB). Blood gas was measured immediately and every 6 h within 24 h after CPB. The patients in the calcium supplement group were given 1 g of calcium gluconate when hypocalcemia occurred, while the control group received no calcium supplementation. Values of radial arterial blood PTH and calcium ion (Ca2+) were measured in the two groups before operation (T1), at 30 min after starting CPB (T2), immediately after stopping CPB (T3), at 24 h after operation (T4), and at 48 h after operation (T5), respectively.ResultsThere were 71 patients enrolled in this study finally, including 38 in the calcium supplement group and 33 in the control group. The PTH values of patients in the two groups gradually increased, reached the peak at T3 time-point, then began to recover gradually. There was no significant difference between the two groups at T1, T2 or T3 time-point (P>0.05), while there were significant differences at T4 and T5 time-points (P<0.05). The Ca2+ values of the two groups gradually decreased after CPB, and gradually increased after blood ultrafiltration. There was no significant difference between the two groups at T1 or T3 time-point (P>0.05), while there were significant differences at T2, T4 and T5 time-points (P<0.05). The postoperative 24-hour values of ejection fraction (EF) and cardiac troponin T (cTnT) and the 72-hour total amount of epinephrine used in the calcium supplement group were (42.66±4.18)%, (1 881.17±745.71) ng/L, and (3.04±0.86) mg, respectively, and those in the control group were (40.76±3.39)%, (2 725.30±1 062.50) ng/L, and (4.69±1.37) mg, respectively. There were statistically significant differences in EF, cTnT and the 72-hour total amount of epinephrine used between the two groups (P<0.05). Values of PTH at T4 and T5 time-points were respectively negatively correlated with postoperative 24-hour value of EF (r=-0.324, P=0.006; r=-0.359, P=0.002), positively correlated with postoperative 24-hour value of cTnT (r=0.238, P=0.046; r=0.248, P=0.037) and the 72-hour total amount of epinephrine used (r=0.324, P=0.006; r=0.383, P=0.001).ConclusionsHyperparathyroidism occures after CPB, and calcium supplementation could relieve the hyperparathyroidism. Hyperparathyroidism may be related to postoperative cardiac insufficiency.

        • The Relation Between Preoperative Pulmonary Artery Pressure and Postoperative Complications in Heart Transplantation Patients and the Prevention and Treatment to Postoperative Complications

          Objective To analyze the relation between preoperative pulmonary artery pressure(PAP) and postoperative complications in heart transplant patients, and summarize the experience of perioperative management of pulmonary hypertension (PH), to facilitate the early period heart function recovery of postoperative heart transplant patients. Methods A total of 125 orthotopic heart transplant patients were divided into two groups according to preoperative pulmonary arterial systolic pressure(PASP) and pulmonary vascular resistance(PVR), pulmonary [CM(1583mm]hypertension group (n=56): preoperativePASPgt;50 mm Hg or PVRgt;5 Wood·U; control group (n=69): preoperative PASP≤50 mmHg and PVR≤5 Wood·U. Hemodynamics index including preoperative cardiac index (CI),preoperative and postoperative PVR and PAP were collected by SwanGanz catheter and compared. The extent of postoperative tricuspid regurgitation was evaluated by echocardiography. Postoperative pulmonary hypertension was treated by diuresis,nitrogen oxide inhaling,nitroglycerin and prostacyclin infusion, continuous renal replacement therapy(CRRT)and extracorporeal membrane oxygenation(ECMO). Results All patients survived except one patient in pulmonary hypertension group died of multiorgan failure and severe infection postoperatively in hospital. Acute right ventricular failure occurred postoperatively in 23 patients, 10 patients used ECMO support, 10 patients with acute renal insufficiency were treated with CRRT. 124 patients were followed up for 2.59 months,7 patients died of multiple organ failure, infection and acute rejection in follow-up period, the survivals in both groups have normal PAP, no significant tricuspid regurgitation. No significant difference in cold ischemia time of donor heart, cardiopulmonary bypass(CPB) and circulation support time between both groups; but the patients of pulmonary hypertension group had longer tracheal intubation time in comparison with the patients of control group (65±119 h vs. 32±38 h, t=2.17,P=0.028). Preoperative PASP,mean pulmonary artery pressure(MPAP) and PVR in pulmonary hypertension group were significantly higher than those in control group, CI was lower in pulmonary hypertension group [PASP 64.30±11.50 mm Hg vs. 35.60±10.20 mm Hg; MPAP 43.20±8.50 mm Hg vs. 24.20±7.20 mm Hg; PVR 4.72±2.26 Wood·U vs. 2.27±1.24 Wood·U; CI 1.93±0.62 L/(min·m2) vs. 2.33±0.56 L/(min·m2); Plt;0.05]. Postoperative early PASP, MPAP and PVR in pulmonary hypertension group were significantly higher than those in control group (PASP 35.40±5.60 mm Hg vs. 31.10±5.70 mm Hg, MPAP 23.10±3.60 mm Hg vs. 21.00±4.00 mm Hg, PVR 2.46±0.78 Wood·U vs. 1.79±0.62 Wood·U; Plt;0.05). Conclusion Postoperative right heart insuficiency is related to preoperative pulmonary hypertension in heart transplant patients. Donor heart can quickly rehabilitate postoperatively by effectively controlling perioperative pulmonary hypertension with good follow-up results.

        • Changes of pulmonary circulation and right ventricular function after lung volume reduction surgery

          Objective To investigate the changes of pulmonary circulation and right ventricular function after lung volume reduction surgery. Methods We retrospectively analyzed the clinical data of 34 patients of severe chronic obstructive pulmonary disease with single or double lung volume reduction surgery through thoracoscope in our hospital from 2013 through 2014. Ultrasonic testing was conducted peroperatively, on postoperative day 3–5, at 1 month and 3 months after surgery. Results Right ventricular stroke volume (61.00±10.54 ml vs. 38.34±10.04 ml) and right ventricular ejection fraction decreased (58.00%±9.00% vs. 49.00%±10.00%), mean pulmonary arterial pressure (23.35±5.07 mm Hg vs. 29.57±6.32 mm Hg) and total pulmonary vascular resistance (9.28±2.14 mm Hg vs. 12.05±4.36 mm Hg) increased with statistical differences (P<0.05) on postoperative day 3–5. Right heart ejection fraction was 51%±11% with a statistical increase (P<0.05) at 1 month after surgery. There was no statistical difference in indicators above between 3 months after surgery and before surgery. Conclusion Changes of pulmonary circulation and right ventricular function may be temporary. Right ventricular dysfunction decreases, pulmonary arterial pressure, and total pulmonary vascular resistance increases on postoperative day 3–5 d. But the changes gradually recover in 1–3 months after surgery, and could be gradually restored to preoperative level.
