Objective:To correlate neutrophil/lymphocyte ratio (NLR) with cardiac function in patients with acute myocardial infarction (ACI) after percutaneous coronary intervention (PCI) and investigate its clinical value in predicting major adverse cardiovascular events (MACEs) in patients.Methods:A total of 120 patients with AMI who underwent PCI at Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from March 2020 to February 2023 were included in this prospective study. The difference in NLR measured 1 day after PCI relative to that measured at 5 days after surgery (?NLR) was correlated with cardiac function ultrasound indicators measured at 3 months after surgery, myocardial injury, and inflammatory biochemical indicators at 1 day after surgery. The MACEs occurring within 3 months after surgery were recorded. The value of ΔNLR recorded during the early stage after PCI for predicting MACEs in patients with AMI was evaluated.Results:At 3 months after surgery, 13 out of 120 patients with AMI (10.83%) had MACEs. The ?NLR in patients with AMI who had MACEs was (3.55 ± 0.47), which was significantly higher than (2.06 ± 0.34) in patients with AMI who had no MACEs ( t = 17.25, P < 0.001). An optimal critical value of ?NLR for predicting MACEs after PCI in patients with AMI was 2.75, with an area under the receiver operating characteristic curve of 0.972, a sensitivity of 90.70%, and a specificity of 91.10%. Conclusion:Increased NLR during the early stage after PCI in patients with AMI is closely related to decreased cardiac function, and worsened myocardial injury and inflammatory reactions. Changes in NLR after PCI in patients with AMI have a highly valuable value for predicting MACEs in these patients.

Objective:To correlate serum Nesfatin-1, N-terminal pro-brain natriuretic peptide (NT-proBNP), and cystatin C (CysC) levels with myocardial enzymes and cardiac function in patients with acute ST-elevation myocardial infarction (STEMI).Methods:This is a case-control study. A total of 100 patients with acute STEMI who received treatment at Lishui People's Hospital from January 2020 to December 2022 were included in the STEMI group. An additional 80 healthy controls who concurrently received physical examinations in the same hospital were included in the control group. Serum levels of Nesfatin-1, NT-proBNP, CysC, creatine kinase-MB (CK-MB), and cardiac troponin I (cTnI) levels were determined in each group. Left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVDD), and left ventricular end-systolic diameter (LVDS) were measured using color Doppler ultrasound. Correlation analysis was performed.Results:Serum Nesfatin-1 level in the STEMI group was (89.96 ± 15.25) ng/L, which was significantly lower than (226.36 ± 37.47) ng/L in the control group ( t = 33.15, P < 0.05). Serum levels of NT-proBNP and CysC in the STEMI group were (1 325.12 ± 378.48) ng/L and (1.37 ± 0.24) mg/L, which were significantly higher than (78.95 ± 13.42) ng/L and (0.79 ± 0.16) mg/L in the control group ( t = -29.42, -18.56, both P < 0.05). Serum CK-MB and cTnI levels in the STEMI group were (46.51 ± 12.14) U/L and (1.13 ± 0.25) U/L, respectively, which were significantly higher than (12.23 ± 4.01) U/L and (0.09 ± 0.02) U/L in the control group ( t = -24.06, -37.09, both P < 0.05). The LVEF in the STEMI group was (37.84 ± 5.45)%, which was significantly lower than (72.41 ± 4.26)% in the control group ( t = 46.49, P < 0.05). The LVDD and LVDS in the STEMI group were (40.92 ± 5.25) mm and (58.98 ± 6.25) mm, which were significantly higher than (19.86 ± 3.36) mm and (34.21 ± 4.38) mm in the control group ( t = -31.13, -30.03, both P < 0.05). Serum Nesfatin-1 level was positively correlated with LVEF ( r = 0.572), but it was negatively correlated with serum CK-MB and cTnI levels, LVDD, and LVDS ( r = -0.498, -0.617, -0.506, -0.534, all P < 0.05). Serum NT-proBNP and CysC levels were negatively correlated with LVEF ( r = -0.653, -0.607), but they were positively correlated with serum CK-MB and cTnI levels, LVDD, and LVDS ( r = 0.582, 0.526, 0.712, 0.565, 0.631, 0.578, 0.659, 0.635, all P < 0.05). Conclusion:Serum Nesfatin-1 levels decrease, while serum NT-proBNP and CysC levels increase in patients with acute STEMI. Serum Nesfatin-1, NT-proBNP, and CysC levels are closely related to myocardial enzymes and cardiac function.

Objective:To analyze the electrocardiographic characteristics of patients with chronic pulmonary artery stenosis (PAS), and to explore their relationship with disease severity indicators.Methods:The study was a retrospective case-series analysis. Patients with chronic PAS admitted to Gansu Provincial Hospital from January 2018 to July 2021 were enrolled. The clinical data and the results of electrocardiography, transthoracic echocardiography, right cardiac catheterization, N-terminal B-type natriuretic peptide (NT-proBNP) measurement and 6-min walking distance test of patients were analyzed. The linear regression model or logistic regression model was used to analyze the relationship between electrocardiographic characteristics and the disease severity in patients with chronic PAS.Results:Sixty-three patients aged (62.1±9.7) years including 43 females (68.3%) were enrolled in the study. Among them, 62 patients (98.4%) had (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ)<1.5 mV, and no patients had V 5lead R: S ratio to V 1 lead R: S<0.04 and V 6 lead R: S ratio<0.4. There were 55 patients (87.3%), with flat or inverted T-waves in V 1, and 10 patients (15.9%) with flat or inverted T-waves in all precordial leads (V 1-V 6). There were 18 patients (28.6%) with flat or inverted T-waves in inferior leads (Ⅱ, Ⅲ, aVF). Multiple liner regression analysis showed that Max R V1, 2+Max S I, aVL-S V1 combined with the number of flat or inverted T-waves in limb leads was independently correlated with atrial area ( R2=0.290, P=0.002); R V1+S V5 was independently correlated with right ventricular area ( R2=0.257, P=0.001); R peak V 1 combined with the number of flat or inverted T waves in precordial leads was independently correlated with tricuspid annular plane systolic excursion ( R2=0.407, P<0.001); (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ) combined with the number of flat or inverted T waves in precordial leads was independently correlated with NT-proBNP ( R2=0.504, P<0.001); Max R V1, 2+Max S I, aVL-S V1 were independently correlated with right atrial pressure ( R2=0.803, P=0.036); (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ) were independently correlated with mean pulmonary artery pressure ( R2=0.302, P<0.001); R aVRcombined with the number of flat or inverted T-waves in precordial leads was independently correlated with cardiac index ( R2=0.173, P=0.003); (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ) was independently correlated with pulmonary vascular resistance ( R2=0.173, P=0.002); R peak V 1 combined with the number of flat or inverted T-waves in precordial leads was independently correlated with mixed vein oxygen saturation ( R2=0.302, P<0.001). Conclusion:The vast majority of patients with chronic PAS have (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ)<1.5 mV and flat or inverted T-wave in V 1 lead, and some characteristic electrocardiographic manifestations are correlated with indicators of disease severity.

Objective:To explore the perinatal characteristics and early postnatal circulatory function of the larger fetus in monochorionic diamniotic twin pregnancy complicated with selective intrauterine growth restriction (sIUGR).Methods:From February 2018 to August 2022, a total of 91 larger fetuses of the sIUGR pregnancies who were hospitalized in the neonatal intensive care unit of Peking University Third Hospital were retrospectively included. The perinatal factors, clinical monitoring indicators, and echocardiographic data of the larger twins in pregnancies with three types of sIUGR were compared using one-way analysis of variance and LSD test, Kruskal-Wallis H test, Chi-square test, and Bonferroni correction. Results:The gestational age, birth weight, and placental weight were (30.6±1.5) weeks, (1 503.9±286.4) g, and (548±120) g in the type Ⅱ sIUGR larger twins and were (30.5±2.3) weeks, (1 523.5±424.4) g, and (560±109) g in type Ⅲ, which were all smaller, lower, and lighter than those in the type Ⅰ[(33.0±1.7) weeks, (2 022.1±372.3) g, and (630±131) g, respectively] (LSD test, all P<0.05). Compared with type Ⅰ sIUGR larger twins, type Ⅱ and Ⅲ sIUGR larger twins had longer hospital stay [36.0 d (27.0-43.0 d) and 32.0 d (15.0-47.0 d) vs. 17.0 d (9.5-22.0 d)], higher proportion of preterm births due to fetal distress [63.6% (21/33) and 75.0% (15/20) vs. 31.6% (12/38), χ2=7.30 and 9.93] (Bonferroni correction, all P<0.017); Compared with type Ⅰ sIUGR larger twins, type Ⅱ sIUGR larger twins had higher proportion of postnatal use of vasoactive drugs [45.5% (15/33) vs. 18.4% (7/38), χ2=6.04, P=0.014]. The interventricular septum thickness was larger in the type Ⅲ sIUGR larger twins than those in the type Ⅰ and Ⅱ twins [(4.4±1.4) vs. (3.8±0.9) and (3.3±0.9) mm]; the thickness of left ventricular free wall was the largest in the type Ⅲ larger twins, followed by those in the type Ⅰ and type Ⅱ [(4.6±1.3) vs. (3.1±0.7) vs. (2.7±0.6) mm]; the left ventricular end-diastolic diameter, right ventricular outflow tract diameter, right ventricular anteroposterior diameter, and pulmonary artery diameter in type Ⅰ larger twins were increased comparing with those in type Ⅱ and Ⅲ [left ventricular end-diastolic diameter: (15.0±2.1) vs. (13.4±2.3) and (12.3±3.2) mm; right ventricular outflow tract diameter: (8.7±1.4) vs. (7.3±1.4) and (7.1±0.8) mm; right ventricular anteroposterior diameter: (7.1±1.5) vs. (6.5±0.9) and (6.4±1.0) mm; pulmonary artery diameter: (6.8±1.1) vs. (6.3±0.9) and (6.3±0.8) mm] (LSD test, all P<0.05). Conclusion:The larger fetuses of type Ⅱ and Ⅲ sIUGR pregnancies had smaller gestational age and lighter birth weight who are more prone to have fetal distress, so it is necessary to strengthen dynamic monitoring and circulatory support for such neonates during the perinatal period and early postnatal period. The thickening of the left ventricular wall and interventricular septum in the early postnatal period of type Ⅲ larger fetuses may lead to the decrease of ventricular diastolic function reserve, thereby the evaluation and monitoring of the myocardial diastolic function of these neonates in the early postnatal period are critical.
摘要
Resumo Fundamento: A cardiomiopatia associada à lipodistrofia parcial (LP) ainda não foi bem descrita. Objetivo: Caracterizar a morfologia e a função cardíaca na LP. Métodos: Pacientes com LP e controles foram avaliados prospectivamente por ecocardiografia transtorácica e ecocardiografia por speckle-tracking (Strain Longitudinal Global, SLG). A relação entre as variáveis ecocardiográficas e o diagnóstico de LP foi testada com modelos de regressão, considerando o efeito da pressão arterial sistólica (PAS). Adotou-se um nível de significância de 5%. Resultados: Vinte e nove pacientes com LP foram comparados com 17 controles. Eles não se diferiram quanto à idade (p=0,94), sexo ou índice de massa corporal (p= 0,05). Os pacientes com LP apresentaram PAS estatisticamente mais alta (p=0,02) em comparação aos controles. Ainda, os pacientes com LP apresentaram maior dimensão do átrio (37,3 ± 4,4 vs. 32,1 ± 4,3 mm, p= 0,001) e maior volume atrial (30,2 ± 7,2 vs. 24,9 ± 9,0 mL/m2, p=0,02), massa do Ventrículo Esquerdo (VE) (79,3 ± 17,4 vs. 67,1 ± 19,4; p=0,02), e parâmetros sistólicos reduzidos do VE (E' lateral, p= 0,001) (E' septal, p= 0,001), (razão E/E', p= 0,02). A fração de ejeção do VE (64,7 ± 4,6 vs. 62,2 ± 4,4 %, p = 0,08) e o SLG não foram estatisticamente diferentes entre os grupos (-17,1±2,7 vs-18.0 ± 2,0%, p= 0,25). Observou-se uma reação positiva do átrio esquerdo (β 5,6; p<0,001), espessura da parede posterior (β 1,3; p=0,011), E' lateral (β -3,5; p=0,002) e E' septal (β -3,2; p<0,001) com o diagnóstico de LP, mesmo após o ajuste para a PAS. Conclusão: Os pacientes com LP apresentam hipertrofia do VE, aumento do átrio esquerdo, e disfunção diastólica do VE apesar de fração de ejeção do VE e SLG preservados. Os parâmetros ecocardiográficos estão relacionados com o diagnóstico de LP, independentemente da PAS.
Abstract Background: Cardiomyopathy associated with partial lipodystrophy (PL) has not been well described yet. Objective: To characterize cardiac morphology and function in PL. Methods: Patients with familial PL and controls were prospectively assessed by transthoracic echocardiography and with speckle-tracking echocardiography (global longitudinal strain, GLS). The relationship between echocardiographic variables and PL diagnosis was tested with regression models, considering the effect of systolic blood pressure (SBP). Significance level of 5% was adopted. Results: Twenty-nine patients with PL were compared to 17 controls. They did not differ in age (p=0.94), gender or body mass index (p= 0.05). Patients with PL had statistically higher SBP (p=0.02) than controls. Also, PL patients had higher left atrial dimension (37.3 ± 4.4 vs. 32.1 ± 4.3 mm, p= 0.001) and left atrial (30.2 ± 7.2 vs. 24.9 ± 9.0 mL/m2,p=0.02), left ventricular (LV) mass (79.3 ± 17.4 vs. 67.1 ± 19.4, p=0.02), and reduced diastolic LV parameters (E' lateral, p= 0.001) (E' septal, p= 0.001), (E/E' ratio, p= 0.02). LV ejection fraction (64.7 ± 4.6 vs. 62.2 ± 4.4 %, p= 0.08) and GLS were not statistically different between groups (-17.1 ± 2.7 vs. -18.0 ± 2.0 %, p= 0.25). There was a positive relationship of left atrium (β 5.6, p<0.001), posterior wall thickness, (β 1.3, p=0.011), E' lateral (β -3.5, p=0.002) and E' septal (β -3.2, p<0.001) with PL diagnosis, even after adjusted for SBP. Conclusion: LP patients have LV hypertrophy, left atrial enlargement, and LV diastolic dysfunction although preserved LVEF and GLS. Echocardiographic parameters are related to PL diagnosis independent of SBP.

@#Objective To investigate the effect of concomitant tricuspid valve repair during mitral valve surgery on the early and mid-term prognosis of the tricuspid valve and right heart function in the patients with moderate or less tricuspid regurgitation. Methods A retrospective study of 461 patients with mitral valve disease requiring cardiac surgery combined with moderate or less tricuspid regurgitation in our hospital from 2011 to 2014 was done. They were 309 males and 152 females with a median age of 53.00 (44.00, 60.00) years. According to whether they received tricuspid valve repair (Kay’s annuloplasty, DeVega’s annuloplasty or annular ring implantation), the patients were divided into a mitral valve surgery only group (a nTAP group, n=289) and a concomitant tricuspid valve repair group (a TAP group, n=172). At the same time, 43 patients whose tricuspid valve annulus diameter was less than 40 mm in the TAP group were analyzed in subgroups. Results The median follow-up duration was 3.00 years (range from 0.10 to 9.30 years). There was no perioperative death. Three months after surgery, the anteroposterior diameter of the right ventricle in the TAP group was significantly improved compared with that in the nTAP group [–1.00 (–3.00, 1.00) mm vs. 0.00 (–0.20, 2.00) mm, P=0.048]. Three years after surgery, the improvement of right ventricular anteroposterior diameter in the TAP group was still significant compared with the nTAP group [–1.00 (–2.75, 2.00) mm vs. 2.00 (–0.75, 4.00) mm, P=0.014], and the patients in the TAP group were less likely to develop moderate or more tricuspid regurgitation (3.64% vs. 35.64%, P<0.001). Annuloplasty ring implantation was more effective in preventing regurgitation progression (P=0.044). For patients with a tricuspid annulus diameter less than 40 mm, concomitant tricuspid valve repair was still effective in improving the anteroposterior diameter of the right ventricle in the early follow-up (P=0.036). Conclusion Concomitant tricuspid valve repair for patients with moderate or less tricuspid regurgitation during mitral valve surgery can effectively improve the tricuspid valve and right heart function in the early and mid-term after surgery. Annuloplasty ring implantation is more effective in preventing regurgitation progression. Patients whose tricuspid annulus diameter is less than 40 mm can also benefit from concomitant tricuspid repair.
摘要
OBJECTIVES@#To study the left heart structure and functional characteristics of term neonates with intrauterine growth restriction (IUGR).@*METHODS@#This study included 86 term neonates with IUGR admitted to the Neonatal Ward of Beijing Friendship Hospital, Capital Medical University from January 2019 to January 2022 as the IUGR group, as well as randomly selected 86 term neonates without IUGR born during the same period as the non-IUGR group. The clinical data and echocardiographic data were compared between the two groups.@*RESULTS@#The analysis of left heart structure and function showed that compared with the non-IUGR group, the IUGR group had significantly lower left ventricular mass, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, left atrial diameter, end-diastolic interventricular septal thickness, left ventricular posterior wall thickness, left ventricular end-diastolic volume, left ventricular end-systolic volume, and stroke volume (P<0.05) and significantly higher ratio of end-diastolic interventricular septal thickness to left ventricular posterior wall thickness, proportion of neonates with a mitral peak E/A ratio of ≥1, and cardiac index (P<0.05). The Spearman correlation analysis suggested that stroke volume was positively correlated with birth weight and body surface area (rs=0.241 and 0.241 respectively; P<0.05) and that the ratio of end-diastolic interventricular septal thickness to left ventricular posterior wall thickness was negatively correlated with birth weight and body surface area (rs=-0.229 and -0.225 respectively; P<0.05).@*CONCLUSIONS@#The left ventricular systolic function of neonates with IUGR is not significantly different from that of neonates without IUGR. However, the ventricular septum is thicker in neonates with IUGR. This change is negatively correlated with birth weight and body surface area. The left ventricular diastolic function may be impaired in neonates with IUGR.

Objective:To investigate the clinical efficacy of daggliflozin in the treatment of type 2 diabetes mellitus complicated by coronary heart disease and cardiac insufficiency.Methods:Seventy patients with type 2 diabetes mellitus complicated by coronary heart disease and cardiac insufficiency who received treatment in The Second People's Hospital of Liaocheng, The Second Hospital of Liaocheng Affiliated to Shandong First Medical University from March 2021 to February 2022 were included in this study. They were randomly divided into a control group ( n = 35) and an observation group ( n = 35). Based on conventional treatment, the control group was treated with metformin, while the observation group was treated with daggliflozin. Both groups were treated for 6 months. Pre- and post-treatment blood glucose and cardiac function as well as adverse reactions and prognosis were compared between the two groups. Results:After treatment, fasting blood glucose, 2-hour post-prandial glucose, glycosylated hemoglobin, fasting insulin, 2-hour post-prandial insulin level, left ventricular end-diastolic diameter, and peripheral blood N-terminal B-type natriuretic peptide levels in the observation group were (6.69 ± 1.83) mmol/L, (9.30 ± 2.96) mmol/L, (7.50 ± 0.98)%, (9.23 ± 2.80) mIU/L, (55.36 ± 8.38) mIU/L, (52.06 ± 5.39) mm, and (5.02 ± 1.98) μg/L, respectively, and they were (7.68 ± 2.03) mmol/L, (10.98 ± 3.33) mmol/L, (8.09 ± 1.25)%, (10.60 ± 2.26) mIU/L, (60.26 ± 8.98) mIU/L, (55.06 ± 5.86) mm, and (6.16 ± 2.28) μg/L, respectively, in the control group. There were significant differences in these indexes between the two groups ( t = 2.14, 2.23, 2.19, 2.25, 2.36, 2.22, 2.23, all P < 0.05). The left ventricular ejection fraction and 6-minute walking test in the observation group were (40.06 ± 5.26)% and (370.69 ± 52.26) m, which were significantly higher than (37.35 ± 4.33)% and (343.98 ± 38.69) m in the control group ( t = 2.35, 2.43, both P < 0.05). During the treatment period, there were no deaths in either group. Conclusion:Daggliflozin combined with conventional treatment can greatly improve glycemic control in patients with diabetes mellitus complicated by coronary heart disease and cardiac insufficiency. The combined therapy contributes to the improvement in cardiac function and is therefore worthy of promotion.

Objective:To explore the prognostic value of the serum concentration of human soluble stromelysin-2(sST2)combined with ultrasonic left ventricular diastolic function parameters for elderly patients with septic shock.Methods:This prospective study involved 150 elderly patients with septic shock admitted to the intensive care unit(ICU)of the First Hospital of Jiaxing between May 2019 and May 2022.Data on the following parameters were recorded on days 1, 3, 5, and 7 in the ICU: sST2 concentration, mitral early-diastolic inflow peak velocity(E), mitral late-diastolic inflow peak velocity(A), E/A ratio, early diastolic mitral annular velocity(e'), and E/e' ratio.According to the 28-day prognostic outcome obtained during follow-up, patients were divided into a survival group and a death group to compare differences in values of the above parameters between the two groups and at different time points.Logistic regression was used to analyze independent risk factors for 28-day mortality.The receiver operating characteristic(ROC)curve was used to analyze the predictive value for 28-day mortality, and further risk stratification was performed according to optimal cut-off values to compare differences in 28-day mortality under different risk stratification methods.The Kaplan-Meier survival curve was used to compare 28-day cumulative survival under different risk stratification methods and analyze the predictive value of the combination of the parameters for 28-day mortality.Results:On day 5 following ICU admission, e' was lower and E/e' and sST2 were higher in the death group than in the survival group.Univariate and multivariate Logistic regression analysis suggested that sST2(odds ratio: 1.010, P<0.001)was an independent risk factor for 28-day mortality in elderly patients with septic shock.sST2 had a sensitivity of 50.2%, a specificity of 79.1%, and an area under the curve of 0.660 for predicting 28-day mortality in patients with septic shock.The sST2 concentration was 89.3 μg/L on day 5 after ICU admission, which was the clinical cutoff point for predicting 28-day mortality.Based on the risk stratification of sST2 levels, the 28-day mortality rate was higher in the sST2>89.3 μg/L group than in the sST2≤89.3 μg/L group.Kaplan-Meier survival analysis showed that the 28-day cumulative survival rate was significantly lower in the sST2>89.3 μg/L group than in the sST2≤89.3 μg/L group(44.0% vs.66.7%, log-rank test: χ2=9.101, P=0.003).The receiver operating characteristic curve showed that the combination of sST2, e', and E/e' significantly improved the prediction efficiency of 28-day mortality in elderly patients with septic shock, with an area under the curve of 0.844, a sensitivity of 89.7%, and a specificity of 66.5%. Conclusions:sST2 is an independent risk factor for 28-day mortality in elderly patients with septic shock.When combined with e' and E/e', sST2 can more accurately evaluate the survival prognosis of these patients.

Objective:To investigate the clinical significances of evaluation indexes of right heart function injury in patients with BCR-ABL-negative myroproliferative neoplasms (MPN).Methods:The clinical data of 208 patients with BCR-ABL-negative MPN diagnosed in the Second People's Hospital of Lianyungang and Jiangsu Province Hospital from January 2015 to August 2021 were retrospectively analyzed, including 63 cases of primary myelopathic fibrosis (PMF), 39 cases of polycytosis vera (PV) and 106 cases of essential thrombocythemia (ET). The clinical characteristics of patients and the examination results of hematological related indicators were compared among the three groups. The examination results of indexes of right heart function injury were analyzed, including echocardiography, brain natriuretic peptide, soluble growth stimulation expression gene-2 (sST-2), lactate dehydrogenase (LDH), D-dimer, ferritin, β 2-microglobulin, peripheral blood WT1 gene, CD34 + cell count, etc. Results:Of the 208 patients, 109 were male and 99 were female; the median age was 62 years old (23 years old, 89 years old). The differences in levels of hemoglobin, platelet count, D-dimer, LDH and ferritin among PMF, PV and ET patients were statistically significant (all P < 0.05). Color echocardiography was performed in 87 patients, including 26 cases of PMF, 19 cases of PV and 42 cases of ET. Pulmonary artery pressure increased in 69 cases (79.3%), left atrial diameter increased in 76 cases (87.3%), and diameter increased during right ventricular diastolic period in 59 cases (67.8%). There were significant differences in pulmonary artery pressure, left atrial diameter and diameter during right ventricular diastolic period among PMF, PV and ET patients (all P < 0.05). Pearson correlation analysis showed that pulmonary artery pressure was positively correlated with ferritin, LDH, sST-2 and age ( r values were 0.796, 0.768, 0.915 and 0.734, all P<0.05), while it was negatively correlated with platelet count ( r = -2.330, P = 0.034). Conclusions:For BCR-ABL-negative MPN patients, the increase of pulmonary artery pressure, ferritin and LDH and the decreased platelet count and hemoglobin may increase the probability of right heart function impairment. For BCR-ABL-negative MPN patients with the higher levels of ferritin, LDH, sST-2, age, and the lower level of platelet count, the pulmonary artery pressure may be higher.

Objective:To explore the risk factors of early delayed recovery after right ventricular-extrapulmonary arterial(RV-PA)conduit reconstruction.Methods:From 2017 to 2021, the children with RV-PA conduit reconstruction, who were treated in our hospital were retrospectively analyzed.The demographic data and peri-operative clinical data of the patients were collected for statistical analysis.Results:Fifty-five patients were included in the study.The patients were sequenced by the length of ICU stay.The time at the 75th percentile was defined as the critical value for grouping.According to the ICU stay time of the children, they were divided into normal recovery group(ICU stay ≤7 days, n=40)and delayed recovery group(ICU stay>7 days, n=15).The mechanical ventilator time in the whole group was 24(0, 1 408)h, and the ICU stay time was 4(1, 67)d.Six cases required extracorporeal membrane oxygenation (ECMO) support, and two cases died.In the multivariate Logistic regression analysis of two groups, long cardiopulmonary bypass(CPB) time( OR=1.034, 95% CI 1.009-1.061, P=0.009)and poor right ventricular function( OR=9.536, 95% CI 1.010-90.037, P=0.049)were independent risk factors for early delayed recovery. Conclusion:The risk of RV-PA conduit reconstruction is high.The proportion of ECMO support is increased.The mortality rate is higher.Right heart dysfunction and prolonged CPB time are risk factors for delayed postoperative recovery.

Objective:To investigate the efficacy of phenolamine in the treatment of sepsis-induced myocardial dysfunction and its effect on cardiac function, myocardial injury index, and hemodynamics in patients.Methods:The clinical data of 79 patients with sepsis-induced myocardial dysfunction who received treatment in Huangshi Central Hospital, Edong Healthcare Group from February 2017 to February 2020 were retrospectively analyzed. These patients were divided into a control group (without phenolamine treatment, n = 41) and an observation group (with phenolamine treatment, n = 38) according to whether they received phenolamine treatment or not. Clinical efficacy, cardiac function, myocardial injury index, and hemodynamic index pre- and post-treatment were compared between the two groups. Results:There was no significant difference in 28-day mortality rate between the two groups ( P > 0.05). Intensive care unit length of stay and mechanical ventilation duration in the observation group were (9.33 ± 3.52) days and 83.00 (28.50, 138.00) hours, which were significantly shorter than (12.17 ± 4.15) days and 111.00 (47.50, 169.00) hours in the control group ( t = 3.26, Z = -2.27, both P < 0.05). The response rate in the observation group was significantly higher than that in the control group [81.58% (31/38) vs. 60.98% (25/41), χ2 = 4.05, P < 0.05]. After 7 days of treatment, the left ventricular ejection fraction in each group was significantly increased, and the left ventricular end-diastolic diameter and left ventricular end-systolic diameter in each group were significantly decreased compared with before treatment (all P < 0.05). After 7 days of treatment, the left ventricular ejection fraction in the observation group was significantly higher than that in the control group ( t = 3.29, P < 0.05), and left ventricular end-diastolic diameter and left ventricular end-systolic diameter were significantly lower than those in the control group ( t = 5.94, 11.21, both P < 0.05). N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in each group were significantly decreased with time (both P < 0.05). At 24 and 72 hours and 7 days after treatment, N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in the observation group were significantly lower than those in the control group (both P < 0.05). After 7 days of treatment, heart rate in each group decreased significantly compared with that before treatment (both P < 0.05), mean arterial pressure, cardiac index, and stroke output index in each group increased significantly compared with those before treatment (all P < 0.05). After 7 days of treatment, heart rate in the observation group was significantly lower than that in the control group ( t = 4.90, P < 0.05), and mean arterial pressure, cardiac index, and stroke output index in the observation group were significantly higher than those in the control group ( t = 4.37, 3.23, 6.01, all P < 0.05). Conclusion:Phentolamine can improve hemodynamics, reduce myocardial injury and improve cardiac function in patients with sepsis-induced myocardial dysfunction.

Objective:To analyze the relationship between QRS-T angle and R/T ratio on electrocardiograms and cardiac function and major adverse cardiac events (MACEs) in patients with coronary heart disease, evaluate cardiac function in patients with coronary heart disease, and investigate the optimal method to predict the occurrence of MACEs.Methods:A total of 80 patients with coronary heart disease who were admitted to the Affiliated People's Hospital of Ningbo University from January 2019 to May 2022 were included in this study. Their cardiac function was evaluated. QRS-T angle and R/T ratio on electrocardiograms were compared among patients. The relationship between the QRS-T angle and R/T ratio on electrocardiograms and cardiac function in patients with chronic heart disease was analyzed using Spearman's correlation coefficient. All patients received 1 week of standardized treatment. These patients were divided into a MACE group and a non-MACE group according to whether they had a MACE. Univariate and multivariate logistic regression analyses were performed to determine the association of QRS-T angle and R/T ratio on electrocardiograms with the occurrence of MACE in patients with coronary heart disease.Results:The QRS-T angle and R/T ratio on electrocardiograms in patients with New York Heart Association (NYHA) class IV heart failure were (115.75 ± 6.83)° and (4.95 ± 0.89) respectively, which were significantly higher than those in patients with NYHA class II and III heart failure (both P < 0.05). The QRS-T angle and R/T ratio on electrocardiograms in patients with NYHA class III heart failure were higher than those in patients with NYHA class II heart failure (both P < 0.05). Spearman correlation coefficient analysis results showed that the QRS-T angle and R/T ratio on electrocardiograms were positively correlated with NYHA cardiac function classification (both P < 0.05). Univariate logistic regression analysis results showed that low left ventricular ejection fraction, high NYHA class, low-density lipoprotein level, large QRS-T angle, and R/T ratio were the risk factors for developing a MACE in patients with chronic heart disease (all P < 0.05). Conclusion:QRS-T angle and R/T ratio on electrocardiograms increase with the worsening of cardiac function, which is a risk factor for developing a MACE in patients with chronic heart disease. It can be used as an objective and effective factor to evaluate the actual condition of patients in the early diagnosis and treatment of chronic heart disease and provide data support for reasonably optimizing intervention strategies and improving therapeutic effects.

Objective:To investigate the application value of percutaneous coronary intervention in patients with acute coronary syndrome in county-level hospitals.Methods:The clinical data of 51 patients with acute coronary syndrome who received treatment in Feng Tai People's Hospital from January 2020 to January 2022 were retrospectively analyzed. They were divided into a control group ( n = 25) and an observation group ( n = 26). The control group was given standard dual antiplatelet and statin drugs. The observation group underwent percutaneous coronary intervention and stent implantation based on conventional drug treatment. All patients were followed up for 1 year. Cardiac function indexes left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD) were compared between the two groups. The number of readmissions, length of hospital stay, quality of life score, medication, the incidence of complications, and the incidence of adverse cardiovascular events were compared between the two groups. Results:Before treatment, there were no significant differences in LVEF and LVEDD between the two groups (both P > 0.05). After treatment, LVEF was increased, and LVEDD was decreased in each group compared with before treatment. After treatment, LVEF and LVEDD in the observation group were (50.34 ± 5.97)% and (49.01 ± 5.02) mm, respectively, which were significantly superior to (45.61 ± 5.42)% and (52.12 ± 5.24) mm in the control group ( t = -2.96, 2.17, both P < 0.05). After treatment, the number of readmissions in the observation group was significantly less than that in the control group [(0.8 ± 0.1) times vs. (2.1 ± 0.3) times, t = 20.14, P < 0.001]. The length of hospital stay in the observation group was significantly shorter than that in the control group [(12.4 ± 3.1) days vs. (25.3 ± 3.9) days, t = 13.10, P < 0.001]. Quality of life score in the observation group was significantly higher than that in the control group [(85.3 ± 5.9) points vs. (72.5 ± 5.2) points, t = -8.19, P < 0.001]. After treatment, the incidence of adverse cardiovascular events in the observation group was significantly lower than that in the control group [3.9% (1/26) vs. 28.0% (7/25), χ2 = 3.94, P = 0.041). Conclusion:Use of percutaneous coronary intervention in patients with acute coronary syndrome in county-level hospitals is feasible. It can improve patients' cardiac function and has a remarkable clinical effect with a low incidence of adverse cardiovascular events.

Objective:To investigate the clinical efficacy of sacubitril and valsartan combined with bisoprolol in the treatment of chronic heart failure and its effect on N-terminal pro-brain natriuretic peptide (NT-pro BNP) level.Methods:The clinical data of 89 patients with chronic heart failure who received treatment in Jinan 2 nd People's Hospital from January 2020 to April 2022 were retrospectively analyzed. These patients were divided into Group A ( n = 48) and Group B ( n = 41) according to different treatment methods. Group A was treated with sacubitril and valsartan combined with bisoprolol. Group B was treated with sacubitril and valsartan combined with metoprolol. All patients were treated for 3 months. Clinical efficacy as well as heart function and NT-pro BNP level pre- and post-treatment were compared between the two groups. The incidence of adverse reactions was calculated in each group. Results:Total response rate in group A was significantly higher than that in group B [95.83% (46/48) vs. 82.93% (34/41), χ2 = 4.05, P < 0.05]. After treatment, the left ventricular ejection fraction in both groups increased significantly and the left ventricular ejection fraction in group A was significantly higher than that in group B ( t = 2.19, P < 0.05). After treatment, NT-pro BNP level in group A was (416.51 ± 30.56) ng/L, which was significantly lower than (450.20 ± 35.79) ng/L in group B ( t = 4.79, P < 0.001). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:The efficacy of sacubitril and valsartan combined with bisoprolol in the treatment of chronic heart failure is superior to that of sacubitril and valsartan combined with metoprolol. The former can greatly decrease NT-pro BNP level. Corresponding drugs can be selected for the treatment of chronic heart failure according to the actual needs of patients.
摘要
ObjectiveTo explore the application value of CT pulmonary angiography (CTPA) in assessing the severity of acute pulmonary embolism (APE) and right heart function in rehabilitation patients. MethodsFrom January, 2013 to January, 2020, 133 inpatients (94 positive and 39 negative) who underwent CTPA examination in Beijing Bo'ai Hospital were involved. Positive patients were further divided into mild, moderate and severe groups based on the pulmonary artery obstruction index (PAOI). The clinical parameters and right heart function indicators were compared. Spearman correlation analysis was used to analyze the correlation between PAOI, and clinical parameters and right heart function indicators, and Logistic regression analysis was used to predict the risk factors of APE. ResultsThere was significant difference in lower extremity venous thrombosis, D-dimer, oxygen partial pressure, PAOI and left process of interventricular septum among four groups (H ≥ 12.350, P < 0.01). PAOI was moderately positively correlated with D-dimer (r = 0.443, P < 0.001) and left process of interventricular septum (r = 0.520, P < 0.001), and was weakly positively correlated with lower extremity venous thrombosis (r = 0.399, P < 0.001), left pulmonary artery diameter (r = 0.213, P = 0.014) and inferior vena cava regurgitation (r = 0.229, P = 0.008). Lower extremity venous thrombosis (OR = 7.708, P < 0.001) and left process of interventricular septum (OR = 3.641, P = 0.008) were independent risk factors for the onset of APE. The combination of the two indicators was effective for diagnosis of APE, and AUC was 0.795 (95% CI 0.715 to 0.874). ConclusionCTPA may be applied to evaluate the severity of APE and right heart function in rehabilitation patients.
