Abstract Objective: Reliably prediction models for coronary artery abnormalities (CAA) in children aged > 5 years with Kawasaki disease (KD) are still lacking. This study aimed to develop a nomogram model for predicting CAA at 4 to 8 weeks of illness in children with KD older than 5 years. Methods: A total of 644 eligible children were randomly assigned to a training cohort (n = 450) and a validation cohort (n = 194). The least absolute shrinkage and selection operator (LASSO) analysis was used for optimal predictors selection, and multivariate logistic regression was used to develop a nomogram model based on the selected predictors. Area under the receiver operating characteristic curve (AUC), calibration curves, Hosmer-Lemeshow test, Brier score, and decision curve analysis (DCA) were used to assess model performance. Results: Neutrophil to lymphocyte ratio, intravenous immunoglobulin resistance, and maximum baseline z-score ≥ 2.5 were identified by LASSO as significant predictors. The model incorporating these variables showed good discrimination and calibration capacities in both training and validation cohorts. The AUC of the training cohort and validation cohort were 0.854 and 0.850, respectively. The DCA confirmed the clinical usefulness of the nomogram model. Conclusions: A novel nomogram model was established to accurately assess the risk of CAA at 4-8 weeks of onset among KD children older than 5 years, which may aid clinical decisionmaking.

Fundamento: la aterosclerosis es una enfermedad de origen multifactorial que se agrava a consecuencia de un medio ambiente adverso y de estilos de vida no saludables. Las evidencias confirman su inicio desde las etapas más tempranas de la vida. Objetivo: describir la presencia de lesiones ateroscleróticas tempranas en las aortas de fetos y neonatos fallecidos hijos de madres hipertensas. Método: se realizó un estudio descriptivo de tipo transversal que incluyó a los fetos mayores de 22 semanas y neonatos fallecidos hijos de madres hipertensas, a quienes se les realizó autopsia en el departamento de anatomía patológica, del Hospital Universitario Ginecobstétrico Eusebio Hernández Pérez, en el período comprendido entre enero del 2021 hasta diciembre 2022, con un total de 18. Se recogieron los siguientes datos en las historias clínicas: sexo del fallecido, edad gestacional en el momento del parto, peso postparto, edad materna y antecedentes de hipertensión arterial (crónica o gestacional). Se analizaron las 18 aortas (torácicas y abdominales) de los fallecidos seleccionados. Resultados: del total de fallecidos estudiados el 70,6 % presentó lesiones ateroscleróticas tempranas, caracterizadas por engrosamiento de la íntima a modo de cojinete, presencia de linfocitos en la íntima o en la pared arterial cercana a ella y/o macrófagos. En algunos casos se observó una de estas variantes histológicas y en otros la combinación de dos o tres. Conclusiones: las lesiones ateroscleróticas tempranas están presentes en las aortas de la mayoría de los fetos y neonatos estudiados, con predominio en las que presentaban hipertensión gestacional.
Foundation: atherosclerosis is a disease of multifactorial origin that is aggravated as a result of an adverse environment and unhealthy lifestyles. Evidence confirms its onset from the earliest stages of life. Objective: to describe the presence of early atherosclerotic lesions in the aortas of deceased fetuses and neonates born to hypertensive mothers. Method: a descriptive cross-sectional study was carried out that included fetuses older than 22 weeks and deceased neonates born to hypertensive mothers, who underwent autopsy in the pathological anatomy department of the Eusebio Hernández Pérez Gynecobstetric University Hospital, in the period between January 2021 and December 2022, with a total of 18. The following data were collected in the medical records: sex of the deceased, gestational age at the time of delivery, postpartum weight, maternal age, and history of arterial hypertension (chronic or gestational).

Results: of the total number of deceased studied, 70.6 % presented early atherosclerotic lesions, characterized by thickening of the intima as a cushion, presence of lymphocytes in the intima or in the arterial wall close to it and/or macrophages. In some cases, one of these histological variants was observed and in others a combination of two or three. Conclusions: early atherosclerotic lesions are present in the aortas of the majority of the fetuses and neonates studied, with a predominance in those with gestational hypertension.
Résumé
El avestruz (Struthio camelus) pertenece a un grupo de aves terrestres conocidas como ratites. La irrigación de su corazón presenta características muy similares a las de los mamíferos, con arterias distribuidas en la superficie cardíaca. La presencia de una sola arteria coronaria se considera una malformación congénita que podría provocar un déficit de perfusión coronaria y ser causa de sintomatología isquémica. Este estudio tiene como objetivo determinar las características morfológicas y anatómicas de las arterias coronarias en corazones de avestruz, con especial énfasis en la incidencia de malformaciones congénitas y su impacto clínico. Se analizaron 100 corazones de avestruz. Las aves tenían entre 12 a 15 meses de edad, con un peso promedio de 92 kg. Para una visualización precisa, se cateterizaron las arterias coronarias y se inyectó látex de neopreno 650 de Dupont, rojo para la arteria coronaria derecha y amarillo para la arteria coronaria izquierda. Los corazones se fijaron en formol al 10% durante 10 días. Se observaron dos casos en los que la arteria coronaria derecha se originaba como rama colateral de la arteria coronaria izquierda, uno discurría entre la aorta y la arteria pulmonar; el otro, anterior al tronco pulmonar, reemplazando a la arteria coronaria derecha. Las arterias coronarias tenían un diámetro de 3,2 mm y 2,5 mm, y se registró un trayecto de 90,4 mm y 123,4 mm, respectivamente, hasta llegar al margen derecho y la superficie diafragmática del corazón. Estas anomalías coronarias, aunque infrecuentes, pueden tener importantes implicaciones clínicas en avestruces debido a su alta velocidad al correr. La presencia de una arteria coronaria única puede aumentar el riesgo de compresión y, por ende, de isquemia. Estos hallazgos amplían el conocimiento sobre la anatomía coronaria del avestruz y subrayan la necesidad de más investigación para entender mejor sus implicaciones clínicas.
SUMMARY: The ostrich belongs to a group of terrestrial birds known as ratites. Their heart irrigation has characteristics very similar to those of mammals, with arteries distributed on the cardiac surface. The presence of a single coronary artery is considered a congenital malformation that could lead to a deficit in coronary perfusion and be a cause of ischemic symptomatology. We analyzed 100 ostrich hearts. Birds were aged between 12-15 months, with an average weight of 92 kg. For precise visualization, coronary arteries were catheterized and injected with Neoprene Latex 650 by Dupont, red for the right coronary artery, and yellow for the left coronary artery. They were fixed in 10 % formalin for 10 days. Two cases were observed where the right coronary artery originated as a collateral branch of the left coronary artery, one ran between the aorta and the pulmonary artery; the other anterior to the pulmonary trunk, replacing the coronary artery. Coronary arteries had a diameter of 3.2 mm and 2.5 mm; a 90.4 mm and 123.4 mm path was recorded reaching the right margin and diaphragmatic surface of the heart.

Resumo Fundamento As mulheres, em comparação aos homens, apresentam piores resultados após a síndrome coronariana aguda (SCA). No entanto, ainda não está claro se o sexo feminino em si é um preditor independente de tais eventos adversos. Objetivo Este estudo tem como objetivo avaliar a associação entre o sexo feminino e a mortalidade hospitalar após infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST). Métodos Conduzimos um estudo de coorte retrospectivo, recrutando pacientes consecutivos com IAMCSST, internados em um hospital terciário de janeiro de 2018 a fevereiro de 2019. Todos os pacientes foram tratados de acordo com as recomendações das diretrizes atuais. Modelos de regressão logística multivariada foram aplicados para avaliar a mortalidade hospitalar utilizando variáveis de GRACE. A precisão do modelo foi avaliada usando o índice c. Um valor de p < 0,05 foi estatisticamente significativo. Resultados Dos 1.678 pacientes com SCA, 709 apresentaram IAMCSST. A população era composta por 36% de mulheres e a idade média era de 61 anos. As mulheres tinham maior idade (63,13 anos vs. 60,53 anos, p = 0,011); apresentavam hipertensão (75,1% vs. 62,4%, p = 0,001), diabetes (42,2% vs. 27,8%, p < 0,001) e hiperlipidemia (34,1% vs. 23,9%, p = 0,004) mais frequentemente; e apresentaram menor probabilidade de serem submetidas a intervenção coronária percutânea (ICP) por acesso radial (23,7% vs. 46,1%, p < 0,001). A taxa de mortalidade hospitalar foi significativamente maior em mulheres (13,2% vs. 5,6%, p = 0,001), e o sexo feminino permaneceu em maior risco de mortalidade hospitalar (OR 2,79, IC de 95% 1,15-6,76, p = 0,023). Um modelo multivariado incluindo idade, sexo, pressão arterial sistólica, parada cardíaca e classe de Killip atingiu 94,1% de precisão na previsão de mortalidade hospitalar, e o índice c foi de 0,85 (IC de 95% 0,77-0,93). Conclusão Após ajuste para os fatores de risco no modelo de previsão do GRACE, as mulheres continuam em maior risco de mortalidade hospitalar.
Abstract Background Women, in comparison to men, experience worse outcomes after acute coronary syndrome (ACS). However, whether the female sex per se is an independent predictor of such adverse events remains unclear. Objective This study aims to assess the association between the female sex and in-hospital mortality after ST-elevation myocardial infarction (STEMI). Methods We conducted a retrospective cohort study by enrolling consecutive STEMI patients admitted to a tertiary hospital from January 2018 to February 2019. All patients were treated per current guideline recommendations. Multivariable logistic regression models were applied to evaluate in-hospital mortality using GRACE variables. Model accuracy was evaluated using c-index. A p-value < 0.05 was statistically significant. Results Out of the 1678 ACS patients, 709 presented with STEMI. The population consisted of 36% women, and the median age was 61 years. Women were older (63.13 years vs. 60.53 years, p = 0.011); more often presented with hypertension (75.1% vs. 62.4%, p = 0.001), diabetes (42.2% vs. 27.8%, p < 0.001), and hyperlipidemia (34.1% vs. 23.9%, p = 0.004); and were less likely to undergo percutaneous coronary intervention (PCI) via radial access (23.7% vs. 46.1%, p < 0.001). In-hospital mortality rate was significantly higher in women (13.2% vs. 5.6%, p = 0.001), and the female sex remained at higher risk for in-hospital mortality (OR 2.79, 95% CI 1.15-6.76, p = 0.023). A multivariate model including age, sex, systolic blood pressure, cardiac arrest, and Killip class was 94.1% accurate in predicting in-hospital mortality, and the c-index was 0.85 (95% CI 0.77-0.93). Conclusion After adjusting for the risk factors in the GRACE prediction model, women remain at higher risk for in-hospital mortality.

ObjectiveTo investigate the association between estimated glucose disposal rate (eGDR) and the severity of coronary heart disease. MethodsWe conducted a hospital-based cross-sectional study that included 1258 patients (mean age: 62(53-68) years) who underwent coronary angiography for suspected coronary artery disease (53.9% were male). Insulin resistance level (IR) was calculated according to eGDR formula: eGDR = 21.158 - (0.09 × WC) - (3.407 × hypertension) - (0.551 × HbA1c) [hypertension (yes = 1 / no = 0), HbA1c = HbA1c (%)]. Subjects were grouped according to the eGDR quantile. CAD severity was determined by the number of narrowed vessels: no-obstructive CAD group (all coronary stenosis were<50%, n=704), Single-vessel CAD group (only one involved major coronary artery stenosis≥50%, n=205), Multi-vessel CAD group (two or more involved major coronary arteries stenosis≥50%, n=349); Multivariate logistic regression model was used to analyze the association between eGDR and CAD severity. The linear relationship between eGDR and CAD in the whole range of eGDR was analyzed using restricted cubic spline. Subgroup analyses were used to assess the association between eGDR and CAD severity in different diabetic states. Receiver operating characteristic (ROC) curve analysis were used to evaluate the value of eGDR in improving CAD recognition. ResultsA decrease in the eGDR index was significantly associated with an increased risk of CAD severity (OR: 2.79; 95%CI: 1.72~4.55; P<0.001). In multivariate logistic regression models, individuals with the lowest quantile of eGDR (T1) were 2.79 times more likely to develop multi-vessel CAD than those with the highest quantile of eGDR (T3) (OR: 2.79; 95%CI: 1.72~4.55; P<0.001). Multivariate restricted cubic spline analysis showed that eGDR was negatively associated with CAD and multi-vessel CAD (P-nonlinear>0.05). In non-diabetic patients, compared with the reference group (T3), the T1 group had a significantly increased risk of CAD (OR: 1.42; 95% CI: 1.00~2.01; P<0.05) and multi-vessel CAD (OR: 1.86; 95%CI: 1.21~2.86; P<0.05). No statistical association was found between eGDR and CAD in diabetic patients. In ROC curve analysis, when eGDR was added to traditional model for CAD, significant improvements were observed in the model's recognition of CAD and multi-vessel CAD. ConclusionOur study shows eGDR levels are inversely associated with CAD and CAD severity. eGDR, as a non-insulin measure to assess IR, could be a valuable indicator of CAD severity for population.

Objective:To explore the current status of barriers to participation in phaseⅡcoronary artery bypass grafting (CABG) patients and the factors influencing them, and to provide new ideas for reducing barriers to participation in rehabilitation and improving the participation rate in cardiac rehabilitation.Methods:For this study, a cross-sectional survey research method was utilized. The study included 334 patients who underwent CABG and were admitted to the Second Hospital of Hebei Medical University between June 2022 and May 2023. These patients were selected using the convenience sampling method. A General Information Questionnaire, the Cardiac Rehabilitation Barriers Scale (CRBS-C/M), and a Questionnaire on the Knowledge of Information Related to Cardiac Rehabilitation were used to conduct the survey. Multiple linear regression was used to analyze the independent influencing factors on barriers to participation in phase Ⅱ cardiac rehabilitation in post-CABG patients.Results:Out of 334 patients, 248 were males and 86 were females with age (54.74 ± 7.61) years old. The total average score of CRBS-C/M in patients after CABG surgery was 3.20 ± 0.43, with the highest external logistic factors score of 3.42 ± 0.58. The knowledge status score of information related to cardiac rehabilitation was 42.11 ± 7.94. Multiple linear regression analysis revealed that the following factors independently influenced post-CABG patients′ barriers to participating in phaseⅡcardiac rehabilitation: marital status, whether or not they had completed phase I cardiac rehabilitation,number of other comorbidities, knowledge of cardiac rehabilitation information. All of these differences were statistically significant ( t values were -4.87-3.35, all P<0.05). Conclusions:The barriers to participation in phase Ⅱ cardiac rehabilitation in post-CABG patients are at an intermediate to high level, and healthcare professionals should emphasize the assessment of barrier factors in these patients, and target the development and implementation of phase Ⅱ cardiac rehabilitation in terms of the influencing factors.

Objective To investigate the relationship between neutrophil/high-density lipoprotein cholesterol ratio(NHR)and the severity of coronary artery lesions in young adults with acute myocardial infarction.Methods A total of 109 young a-dults(aged 18~45 years)with acute myocardial infarction admitted to the First Affiliated Hospital of Anhui Medical University from June 2019 to June 2023 were selected and divided into Syntax low-risk group(n=85)and Syntax medium-high-risk group(n=24)according to Syntax score.Patients with negative coronary angiography during the same period were negative control group(n=52).General clinical data and related serum markers were collected,and NHR value was calculated.Pearson correla-tion analysis and logistics regression analysis were performed to examine the correlation between NHR and the severity of coro-nary artery lesions.Subgroup analysis and interaction testing were further conducted.The receiver operating curve(ROC)was performed to evaluate the value of NHR in predicting the severity of coronary artery lesions in young adults with acute myocar-dial infarction.Results Gender,smoking rate,alcohol consumption rate,diabetes history,absolute number of neutrophils,tri-glyceride,HDL-C,NHR,VLDL-C,apolipoprotein B(APOB),fasting blood glucose and glycosylated hemoglobin were signifi-cantly different among the three groups(P<0.05).In pairwise comparison,the absolute number of neutrophil and NHR were significantly different among the three groups.BMI was significant different between non-CHD group and Syntax medium-high-risk group.HDL-C,fasting blood glucose and glycosylated hemoglobin were significant different between Syntax low-risk group and non-CHD group,as well as between Syntax medium-high-risk group and non-CHD group(P<0.05).Creatinine and APOB were significant different between Syntax low-risk group and non-CHD group.Triglyceride,VLDL-C and LP(a)were significant different between Syntax low-risk group and Syntax medium-high-risk group(P<0.05).Pearson correlation analysis showed a positively correlation between NHR and Syntax score(r=0.322,P<0.01).Univariate and multivariate binary logistic regres-sion analysis showed that NHR(OR=1.265,95%CI1.097~1.458,P<0.05)was an independent risk factor for the severity of coronary artery lesions in young adults with acute myocardial infarction.Subgroup analysis showed that NHR was significantly associated with the severity of coronary artery lesions in patients with BMI≥24 kg/m2,smokers,drinkers and non-drinkers(P<0.05).No significant difference was observed in interaction analysis.The ROC curve showed that the area under the curve(AUC)predicted by NHR for acute myocardial infarction in young adults was 0.758,with a cut-off value of 7.0319,sensitivity of 83.3%,and specificity of 63.53%.Conclusion NHR has a certain value in predicting the severity of coronary artery lesions in young adults with acute myocardial infarction.
Résumé
Coronary artery calcifications (CAC) is an independent risk factor for cardiovascular disease (CVD). It has been revealed that this condition can be automatically quantified through computerize tomographic (CT) scan contained in radiotherapy plan for patients with breast cancer, with which, physicians can identify the patients with increased risk of CVD after radiotherapy prematurely and take intervention measures in advance. In this article, the current literature and research progress on the correlation between CAC and cardiotoxicity in patients with breast cancer after radiotherapy were reviewed, expecting to provide a strategy to reduce the CVD risk in patients with breast cancer after radiotherapy.

Objective:To investigate the prognostic value of myocardial flow reserve (MFR) measured by SPECT myocardial blood flow (MBF) quantitative technique in patients with intermediate stenoses of coronary arteries.Methods:From September 2019 to May 2021, patients with intermediate stenoses (50% to 80%) identified by invasive coronary angiography in Fuwai Hospital, Chinese Academy of Medical Sciences, Fuwai Center China Cardiovascular Hospital, and TEDA International Cardiovascular Hospital were prospectively included. All patients underwent a one-day rest/stress SPECT myocardial perfusion imaging (MPI) and SPECT MBF quantification. The radioactivity distribution of each segment of the MPI bullseye polar maps were obtained according to the standard 5-point method to obtain the summed stress score (SSS) and the summed difference score (SDS) to determine the existence of abnormality. ROC curve analysis was used to obtain the optimal prognostic cut-off value for MFR. The primary endpoint was defined as cardiovascular endpoint events. Survival and prognostic analyses were conducted by Kaplan-Meier method and Cox proportional hazard models. The difference of AUCs was analyzed by Delong test.Results:A total of 314 patients (194 males, 120 females; age (59.4±8.6) years) were enrolled. Over a median follow-up duration of 754 (range: 628-914) d, 54 patients had endpoint events. ROC curve showed that the prediction ability of MFR was significantly better than that of conventional MPI (AUCs: 0.713 and 0.512; z=3.76, P<0.001). The optimal prognostic cut-off value for MFR to predict endpoint events in patients with intermediate stenoses was 2.04. Cox multivariate analysis showed that MFR (hazard ratio ( HR)=0.434, 95% CI: 0.282-0.669, P<0.001) was an independent predictor of endpoint events in patients with intermediate stenoses. Kaplan-Meier survival analysis showed that the prevalence of endpoint events in patients with MFR≤2.04 was significantly higher than that in patients with MFR>2.04 (25.4%(43/169) vs 7.6%(11/145); χ2=21.27, P<0.001). Conclusion:The MFR measured by SPECT MBF quantitative technique has an independent predictive value for cardiovascular endpoint events in patients with intermediate stenoses.

Objective:To compare the efficacy of pecto-intercostal fascial plane (PIFP) block versus transversus thoracic muscle plane (TTP) block under ultrasound guidance in coronary artery bypass grafting with general anesthesia.Methods:Ninety American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ patients of either sex, aged 50-79 yr, scheduled for elective coronary artery bypass grafting, were divided into 3 groups ( n=30 each) using a random number table method: PIFP block combined with general anesthesia group (PG group), TTP block combined with general anesthesia group (TG group), and general anesthesia group (G group). After anesthesia induction, bilateral PIFP block was performed under ultrasound guidance in group PG, TTP block was performed under ultrasound guidance in group TG. Three groups used the same general anesthesia method and patient-controlled intravenous analgesia after surgery. Visual analog scale scores (cough, position change, etc) at rest and during activity were recorded at 6, 12, 18 and 24 h after operation. The total consumption of intraoperative sufentanil, extubation time, length of stay in intensive care units, rate of rescue analgesia, effective pressing times of patient-controlled analgesia, incidence of postoperative nausea and vomiting, skin pruritus and nerve block-related adverse events were recorded. The operation time of nerve block was recorded and ultrasound-guided needle visibility score was assessed in PG group and TG group. Results:Compared with group G, the total consumption of intraoperative sufentanil was significantly reduced, the extubation time and length of stay in intensive care units were shortened, visual analog scale scores at rest and during activity were decreased at 6, 12 and 18 h after operation, the rate of rescue analgesia was decreased, and the effective pressing times of patient-controlled analgesia were decreased in group PG and group TG ( P<0.05), and no significant change was found in the aforementioned parameters in PG and TG groups ( P> 0.05). Compared with group TG, the operational time of nerve block was significantly shortened, and the ultrasound-guided needle visibility score was increased in group PG ( P<0.05). No nerve block-related adverse events were found in PG and TG groups. There was no significant difference in the incidence of postoperative nausea and vomiting and skin pruritus among the three groups ( P>0.05). Conclusions:PIFP block can provide good perioperative analgesia and promote the rapid recovery in the patients undergoing coronary artery bypass grafting with general anesthesia. Although the analgesic effect of PIFP blockade is similar to that of TTP blockade, PIFP blockade is more clinically valuable due to its simpler operation and less relative risk.

Objective:To evaluate the effect of ulinastatin on the postoperative pulmonary complications (PPCs) in the patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:Medical records from patients scheduled for elective OPCABG from September 2021 to August 2023 were retrospectively collected. The patients were divided into ulinastatin and control groups based on the intraoperative use of ulinastatin. Confounding factors were adjusted using propensity score matching and an extended Cox proportional hazards model. The primary outcome was the development of PPCs within 30 days after surgery, and secondary outcomes included length of stay in intensive care unit, length of hospital stay and occurrence of other adverse events.Results:A total of 1 532 patients were included in this cohort study, and 585 cases (38.2%) experienced PPCs. Compared with control group, the incidence of PPCs was significantly decreased (before matching: 42.7% vs. 35.2%, P=0.004; after matching: 42.2% vs. 35.6%, P=0.033), the incidence of acute kidney injury was decreased and no significant differences were found in the length of stay in intensive care unit, length of hospital stay and incidence of other adverse events in ulinastatin group ( P>0.05). In the extended Cox proportional hazard model before and after adjustment for confounding factors, the risk of PPCs was significantly reduced after the use of ulinastatin ( HR value before adjustment was 0.81, 95% confidence interval [ CI] 0.67-0.99, P=0.004; the HR value after adjustment was 0.79, 95% CI 0.65-0.96, P=0.022). The risk of PPCs was significantly decreased in patients aged >65 yr and at high risk of PPCs after using ulinastatin ( HR=0.667, 95% CI 0.542-0.821, P<0.001; hR value was 0.641, 95% CI 0.516-0.812, P<0.001). Conclusions:The intraoperative use of ulinastatin is helpful in decreasing the risk of PPCs in patients undergoing OPCABG.

OBJECTIVE To compare the effects of roxadustat and recombination human erythropoietin (rHuEPO) on coronary artery calcification in maintenance hemodialysis (MHD) patients. METHODS In retrospective analysis, MHD patients prescribed roxadustat in the Blood Purification Center of the First Affiliated Hospital of Chongqing Medical University from April 2019 to June 2021 were selected as the ROX group (56 patients), and MHD patients prescribed rHuEPO during the same period were selected as the EPO group (60 patients), and follow-up observation was conducted for 12 months. The differences in laboratory index, coronary artery calcification score (CACS), and cardiac ultrasound parameters before and after treatment as well as the occurrence of cardiac and cerebrovascular adverse events during follow-up period were compared between the two groups. RESULTS There was no statistical difference in CACS between the two groups before and after treatment (P>0.05); but the difference of CACS in the ROX group was significantly lower than the EPO group (P<0.05). There was no statistically significant difference in cardiac ultrasound parameters and laboratory indexes between the two groups before and after treatment (P<0.05). The incidence of apoplexy and myocardial infarction in the ROX group was lower than that in the EPO group (P<0.05), and there was no statistically significant difference in the incidence of hospitalization due to heart failure between the two groups (P>0.05). CONCLUSIONS Compared with rHuEPO, roxadustat may have a positive effect on delaying coronary artery calcification in MHD patients and may be beneficial in reducing the incidence of myocardial infarction and apoplexy in MHD patients.

@#Objective To summarize and explore the individualized surgical treatment strategy and prognosis of anomalous aortic origin of coronary artery (AAOCA). Methods The clinical data of children with AAOCA admitted to Shanghai Children's Medical Center from March 2018 to August 2021 were retrospectively analyzed. Results A total of 17 children were enrolled, including 13 males and 4 females, with a median age of 88 (44, 138) months and a median weight of 25 (18, 29) kg. All patients received operations. The methods of coronary artery management included coronary artery decapitation in 9 patients, coronary artery transplantation in 5 patients and coronary artery perforation in 3 patients. One patient with severe cardiac insufficiency (left ventricular ejection fraction 15%) received mechanical circulatory assistance after the operation for 12 days. No death occurred in the early postoperative period, the average ICU stay time was 4.3±3.0 d, and the total hospital stay was 14.4±6.1 d. All the children received regular anticoagulation therapy for 3 months after discharge. The median follow-up time was 15 (13, 24) months. All patients received regular anticoagulation therapy for 3 months after discharge. No clinical symptoms such as chest pain and syncope occurred again. The cardiac function grade was significantly improved compared with that before operation. Imaging examination showed that the coronary artery blood flow on the operation side was unobstructed, and no restenosis occurred. Conclusion AAOCA is easy to induce myocardial ischemia and even sudden cardiac death. Once diagnosed, operation should be carried out as soon as possible. According to the anatomic characteristics of coronary artery, the early effect of individualized surgery is satisfactory, and the symptoms of the children are significantly improved and the cardiac function recovers well in the mid-term follow-up.
Résumé
@#Since the advent of coronary artery bypass grafting (CABG), the selection of bypass conduits has always been one of the most controversial topics in this field. Arterial conduits have received extensive attention due to their excellent biological features and high patency. In recent years, the application of arterial grafting and total arterial grafting in China keeps increasing in recent years, but there is still a gap compared to the Europe and America. Previous clinical studies have indicated the benefits of the total arterial grafting in terms of patency and long-term outcomes, but the advantage of multiple arterial grafting over other procedures is still in need to be confirmed with high-quality randomized controlled trials. This article reviews the clinical application and strategy of total-arterial CABG, aiming to provide objective reference for future clinical research and application.
Résumé
ObjectiveTo explore the correlation between serum albumin levels and coronary artery calcification (CAC) in patients with early-stage chronic kidney disease (CKD), as well as the value of serum albumin levels in predicting the incidence and severity of CAC. MethodsThe study included 391 early-stage CKD patients who underwent coronary computed tomography angiography (CTA) at Sun Yat-sen Memorial Hospital of Sun Yat-sen University between January 2019 and December 2022. Demographic and biochemistry data, as well as the coronary CTA results, were collected. Based on the coronary artery calcification score (CACS), all patients were divided into non-CAC group (CACS=0, n=184) and CAC group (CACS>0, n=207). All patients were further divided into 3 groups based on the serum albumin levels: group A (serum albumin levels<35 g/L, n=30), group B (35 g/L≤ serum albumin levels< 40 g/L, n=198) and group C (serum albumin levels≥ 40 g/L, n=163). Univariate and multivariate binary logistic regression analyses were conducted to investigate the association between serum albumin levels and CAC in early-stage CKD patients. Differences in CAC among groups were analyzed by using post-hoc multiple comparisons and ordinal logistic regression model analysis. ResultsPatients with CAC had significantly lower serum albumin levels than those without CAC (P<0.05). There was a negative correlation between serum albumin levels and CACS in early-stage CKD patients (P<0.01), as serum albumin decreased in levels, CAC increased in severity. ConclusionsOur study shows that early-stage CKD patients with lower serum albumin levels have a higher incidence of CAC. Low serum albumin level is an independent risk factor for CAC progression.
Résumé
ObjectiveTo investigate the application of endoscopy in obtaining the great saphenous vein (GSV) during coronary artery bypass grafting (CABG) and explore the learning curve, with a particular focus on common challenges encountered during the learning process and their impact on early clinical outcomes. MethodsA retrospective analysis was conducted on clinical data from 83 patients who underwent off-pump CABG with endoscopic GSV harvesting at the First Affiliated Hospital of Zhengzhou University from July 2013 to April 2014. Patients were categorized into four groups based on the chronological order of their hospitalization: Group A (novice group, n=20), Group B (proficient group, n=20), Group C (progressive group, n=20), and Group D (mature group, n=23). Differences in perioperative and midterm follow-up outcomes among the groups were analyzed to determine the learning curve period. ResultsThe study population had a mean age of (60.22±8.06) years and a mean body weight of (69.77±11.66) kg. Comorbidities included hypertension (24 cases), diabetes (26 cases), and subacute cerebral infarction (14 cases). The novice group exhibited significantly shorter GSV length-to-harvest time ratio relative to the other three groups (P<0.001) and a significantly higher incidence of main vein damage (P=0.006). However, there was no statistically significant difference in graft patency at the 1-year follow-up. ConclusionThorough and reliable technical training in endoscopic GSV harvesting is essential to minimize vascular injury caused by novice operators. Approximately 20 cases of hands-on experience and a careful self-analysis of procedural challenges are likely required to achieve proficiency in GSV harvesting.
Résumé
Objective:To study correlation between related carotid ultrasound parameters and severity of coronary atherosclerosis(AS).Methods:According to number of diseased coronary arteries,a total of 116 patients with cor-onary heart disease diagnosed by coronary angiography in our hospital were divided into single vessel coronary dis-ease group(n=38,single group),double vessel coronary disease group(n=39,double group)and ≥3 vessel coro-nary disease group(n=39,multiple group).Another 41 healthy subjects were simultaneously regarded as healthy control group.General clinical data and carotid ultrasound parameters were compared among all groups,and corre-lation among them and AS severity was analyzed.Results:Compared with healthy control group,there were signifi-cant rise in levels of total cholesterol(TC),triglycerides(TG)and low density lipoprotein cholesterol(LDL-C),carotid intima-media thickness(IMT)and Crouse score in single,double and multiple groups,and significant re-ductions in plaque echo gray-scale median(GSM)in double and multiple groups.Compared with single group,there were significant rise in levels of TG and LDL-C,Gensini score and Crouse score in double and multiple groups and TC level in multiple group,and significant reduction in plaque echo GSM in multiple group.Compared with double group,there were significant rise in TC level,Gensini score and Crouse score,and significant reduction in plaque echo GSM in multiple group(P<0.05 or<0.01).Pearson correlation analysis indicated that Gensini score was significant positively correlated with Crouse score in these patients(r=0.580,P=0.001).Spearman correla-tion analysis indicated that IMT was significant positively correlated with number of diseased coronary arteries(r=0.582,P=0.001),and plaque echo GSM was significant inversely correlated with it(r=-0.518,P=0.001)in these patients.Conclusion:Related carotid ultrasound parameters are significantly correlated with severity of coro-nary atherosclerosis.
