RESUMEN
Objective To investigate the correlation between serum bicarbonate level and cardiovascular events in peritoneal dialysis(PD)patients.Methods The data of PD patients who underwent PD catheterization and were followed up regularly until March 31,2023 were retrospectively collected.The included patients were divided into low bicarbonate group and normal bicarbonate group according to the time-averaged serum bicarbonate level.The incidence of cardiovascular events(including coronary heart disease,heart failure,stroke,peripheral vascular dis-ease,death related to cardiovascular surgery or death due to aneurysm dissection or rupture,fatal pulmonary em-bolism,or death from other or unknown cardiovascular causes)was compared between the two groups and the risk factors for cardiovascular events were analyzed.Results At the end of follow-up,a total of 110 PD patients were included,and 34 patients had cardiovascular events.Compared with the normal bicarbonate group,the low bicar-bonate group had a higher incidence of cardiovascular events.Univariate Cox regression analysis showed that the risk of cardiovascular events in the low bicarbonate group was 4.197 times higher than that in the normal bicarbon-ate group(95％CI=2.115-8.331,P＜0.001).After adjusting for multiple confounding factors,the risk of car-diovascular events in the low bicarbonate group was 3.506 times higher than that in the normal bicarbonate group(95％CI=1.709-7.193,P=0.001).The results of multivariate competing risk model showed that the risk of cardiovascular events in the low bicarbonate group was 3.801 times higher than that in the normal bicarbonate group(95％CI=1.920-7.525,P＜0.001).Conclusion Low serum bicarbonate level is closely related to the oc-currence of cardiovascular events in patients with PD,and it is an independent risk factor for cardiovascular events in patients with PD.
RESUMEN
Objective To investigate the predictive value of tissue plasminogen activator(t-PA),chro-mogranin A(CgA),and lipoprotein related phospholipase A2(LP-PLA2)in serum for major adverse cardio-vascular event(MACE)after percutaneous coronary intervention(PCI).Methods A total of 120 patients with coronary heart disease who underwent PCI in the hospital from August 2020 to August 2022 were en-rolled in the study.According to whether MACE occurred within 1 year after PCI,the patients were divided into MACE group(33 cases)and non-MACE group(87 cases).The levels of serum t-PA,CgA,LP-PLA2 and clinical data were compared between the MACE group and the non-MACE group.Multivariate Logistic regres-sion was used to analyze the risk factors of MACE after PCI.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of t-PA,CgA and LP-PLA2 alone or in combination for MACE after PCI.Results The proportion of patients with smoking history,NT-proBNP,CgA,LP-PLA2,and the propor-tion of patients with hypertension in the MACE group were higher than those in the non-MACE group(P＜0.05),while left ventricular ejection fraction(LVEF)and t-PA were lower than those in the non-MACE group(P＜0.05).There were no significant differences in age,gender composition,serum creatinine,triglyc-erides(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),drinking history,NYHA cardiac function classification,combined diabetes,application of aspirin,and application of clopidogrel between the two groups(P＞0.05).Multivariate Logistic regression analysis showed that smoking history,increased NT-proBNP,hypertension,decreased LVEF,decreased t-PA,increased CgA and increased LP-PLA2 were risk factors for MACE after PCI(P＜0.05).ROC curve analysis showed that the areas under the curves(AUCs)of serum t-PA,CgA and LP-PLA2 alone or in combination for predicting MACE after PCI were 0.785(95％CI:0.693-0.877),0.678(95％CI:0.564-0.791),0.730(95％CI:0.636-0.824),0.888(95％CI:0.830-0.946),respectively.The efficacy of combined prediction was bet-ter than those of single detections(P＜0.05).Conclusion The lower the serum t-PA level is and the higher the CgA and LP-PLA2 levels are,the greater the risk of MACE after PCI is.The combination of the three in-dicators has higher value in predicting MACE after PCI.

RESUMEN
Objective To construct a nomogram prediction model for major adverse cardiovascular events(MACE)within 1 year after percutaneous coronary intervention(PCI)in elderly patients with acute coronary syndrome(ACS).Methods A retrospective analysis was conducted on 551 patients with diagnosed ACS and undergoing PCI in Department of Cardiovascular Medicine of Air Force Medical Center from 1 January 2020 to 1 April 2022.According to the occurrence of MACE during 1 year of follow-up,they were classified into MACE group(n=176)and non-MACE group(n=375).Risk factors for the occurrence of MACE in elderly ACS patients within 1 year after PCI were analysed using univariate and multivariate logistic regression,a nomogram prediction model was constructed,and the predictive power of the model was assessed using the area under the ROC curve(AUC).Results The MACE group had significantly higher Gensini score,systemic immune-inflammation index,and GRACE score,but obviously lower prognostic nutritional index than the non-MACE group(P＜0.01).Multivariate logistic regression analysis showed that recent smoking(OR=2.222,95％CI:1.361-3.628,P=0.010),hyperlipidaemia(OR=1.881,95％CI:1.145-3.089,P=0.013),prognostic nutritional index(OR=4.645,95％CI:2.788-7.739,P=0.001),LVEF(OR=5.177,95％CI:3.160-8.483,P=0.001),systemic immune-inflammation index(OR=5.396,95％CI:3.179-9.159,P=0.001),and preoperative di-agnosis of non-STEMI(OR=2.829,95％CI:1.356-5.901,P=0.006)or STEMI(OR=3.451,95％CI:1.596-7.463,P=0.002)were independent influencing factors for occurrence of MACE after PCI in elderly ACS patients.ROC curve analysis showed that the AUC value of the nomo-gram model for predicting MACE within 1 year after PCI in elderly ACS patients was 0.888.Con-clusion Our developed nomogram model is simple and practical,and can effectively predict the occurrence of MACE within 1 year after PCI in elderly ACS patients.And external validation should be carried out to ensure its generality.
RESUMEN
Objective To explore the efficacy and safety of enhanced external counterpulsation(EECP)in elderly patients with acute ischemic stroke(AIS)complicated by coronary heart dis-ease(CHD).Methods A total of 65 AIS patients with CHD admitted in our hospital from Janu-ary to June 2023 were recruited and randomly divided into a control group(drug secondary pre-vention,n=32)and a treatment group(drug combined with EECP therapy,n=33).Their NIHSS score,mRS score and Canadian Cardiovascular Society(CCS)angina grade were evaluated before and after treatment and compared between the two groups.The incidences of recurrent ischemic stroke,new hemorrhagic stroke and major adverse cardiovascular events(MACE)were also recor-ded during treatment.Results The NIHSS score and mRS score were significantly decreased in both groups after treatment(P＜0.01).After treatment,the NIHSS score(2.67±1.63 vs 3.56± 1.83),mRS score[1.0(0.0,1.0)vs 2.0(1.0,2.0)]and CCS grade[1.0(1.0,2.0)vs 2.0(1.0,2.0)]were obviously lower in the treatment group than the control group(P＜0.05,P＜0.01).There were no statistical differences in the incidence rates of recurrent ischemic stroke,new-onset hem-orrhagic stroke,and MACE between the control group and the treatment group(9.4％vs 6.1％,6.3％vs 3.0％,12.5％vs 6.1％,P＞0.0 5).Conclusion EECP is a safe and effective treatment option for elderly AIS patients with CHD.
RESUMEN
ObjectiveTo compare the effects and differences of Yiqi Liangxue Shengji Formula （益气凉血生肌方） and atorvastatin on the repair of vascular injury in rats from the perspective of metabolomics. MethodsTwenty-four male SD rats were randomly divided into sham-surgery， model， traditional Chinese medicine （TCM）， and ator-vastatin groups， with 6 rats in each group. The rat model was established by balloon-induced abdominal aorta injury. Gavage was started on the day after surgery in all groups of rats. The sham and model groups were given with deio-nized water， TCM group received Yiqi Liangxue Shengji Formula 6 g/（kg·d）， and the atorvastatin group treated with atorvastatin suspension 2 mg/（kg·d） for 4 weeks. HE staining was used to observe the pathological morphology of the injured segment of the abdominal aorta； ELISA detection was used to test serum nitric oxide （NO） and C-reactive protein （CRP） levels； UPLC MS/MS technology was used for widely targeted metabolomics detection in serum， and multivariate statistical analysis was used to screen metabolic markers and pathways of two drugs； finally， compare serum levels of key metabolic markers of the above two medications in rats of each group. ResultsCompared with the sham-surgery group， the neointima significantly thickened， the level of NO decreased significantly and the level of CRP increased in serum of the model group （P＜0.01）； compared with the model group， the degree of arterial intimal hyperplasia in TCM group and atorvastatin group reduced， with an increase in NO levels and a decrease in CRP levels （P＜ 0.05 or P＜0.01）. The results of serum metabolomics showed that TCM group obtained 49 metabolic markers and 6 metabolic pathways， while atorvastatin group obtained 41 metabolic markers and 4 metabolic pathways. The two medications jointly regulated 38 metabolites. Glycerophospholipid metabolism and arginine-related metabolism were common metabolic pathways for both medications. Lysophosphatidylcholine （16∶1/0∶0） ［LPC （16∶1/ 0∶0）］， phosphatidylcholine （15∶0/15∶0） ［PC （15∶0/15∶0）］ were the key metabolites of glycerophospholipid metabolic pathway； ornithine， spermidine were the key metabolites of arginine-related metabolic pathway. The tricarboxylic acid cycle and glutathione metabolism were the unique metabolic pathways of Yiqi Liangxue Shengji Formula. Compared with the sham-surgery group， LPC （16∶1/0∶0）， ornithine， and spermidine levels elevated and PC （15∶0/15∶0） levels decreased in the model group （P＜0.05 or P＜0.01）. Compared with the model group， LPC （16∶1/0∶0）， ornithine， and spermidine levels decreased， and PC （15∶0/15∶0） levels increased in both TCM group and atorvastatin group （P＜0.05 or P＜0.01）. The degree of LPC reduction （16∶1/0∶0） was more significant in atorvastatin group compared with that in the TCM group （P＜0.01）. ConclusionsBoth sham-surgery and atorvastatin could regulate lipid metabolism and arginine-related metabolism， exert the characteristics of lipid-lowering， anti-inflammatory， improve arginine/NO bioavailability， and improve endothelial dysfunction. Atorvastatin showed more advantages in lipid-lowering and anti-inflammatory， while Yiqi Liangxue Shengji Formula has unique characteristics in regulating energy metabolism and improving oxidative stress.
RESUMEN
Resumen Introducción: el progreso en los tratamientos para el lupus eritematoso sistémico (LES) resultó en una disminución de la mortalidad; sin embargo, la enfermedad cardiovascular y las complicaciones infecciosas aún son las principales causas de muerte. La evidencia apoya la participación del sistema inmunológico en la generación de la placa aterosclerótica, así como su conexión con las enfermedades autoinmunes. Objetivos: describir la frecuencia de eventos cardiovasculares (ECV) en el Registro de Lupus Eritematoso Sistémico de la Sociedad Argentina de Reumatología (RELESSAR) transversal, así como sus principales factores de riesgo asociados. Materiales y métodos: estudio descriptivo y transversal para el cual se tomaron los pacientes ingresados en el registro RELESSAR transversal. Se describieron las variables sociodemográficas y clínicas, las comorbilidades, score de actividad y daño. ECV se definió como la presencia de al menos una de las siguientes patologías: enfermedad arterial periférica, cardiopatía isquémica o accidente cerebrovascular. El evento clasificado para el análisis fue aquel posterior al diagnóstico del LES. Se conformaron dos grupos macheados por edad y sexo 1:2. Resultados: 1515 pacientes mayores de 18 años participaron del registro. Se describieron 80 pacientes con ECV (5,3%). En este análisis se incluyeron 240 pacientes conformando dos grupos. La edad media fue de 47,8 (14,4) y 47,6 (14,2) en el grupo con y sin ECV respectivamente. Los pacientes con ECV tuvieron mayor duración del LES en meses, mayor índice de Charlson, mayor SLICC (Systemic Lupus International Collaborating Clinics/American College of Rheumatology), mayor frecuencia de manifestaciones neurológicas, síndrome antifosfolípido, hospitalizaciones y uso de ciclofosfamida. Las únicas variables asociadas en el análisis multivariado fueron el índice de Charlson (p=0,004) y el SLICC (p<0,001). Conclusiones: los ECV influyen significativamente en nuestros pacientes, y se asocian a mayor posibilidad de daño irreversible y comorbilidades.
Abstract Introduction: progress in treatments for systemic lupus erythematosus (SLE) has resulted in a decrease in mortality; however, cardiovascular and infectious diseases remain the leading causes of death. Evidence supports the involvement of the immune system in the generation of atherosclerotic plaque, as well as its connection to autoimmune diseases. Objectives: to describe the frequency of cardiovascular disease (CVD) in the cross-sectional RELESSAR registry, as well as its associated variables. Materials and methods: a descriptive and cross-sectional study was performed using patients admitted to the cross-sectional RELESSAR registry. Sociodemographic variables, clinical variables, comorbidities, activity and damage scores were described. CVD was defined as at least one of the following: peripheral arterial disease, ischemic heart disease, or cerebrovascular accident. All patients with at least one CVD were included in our analysis (heart attack, central nervous system vascular disease, and peripheral arteries atherosclerotic disease). The event classified for the analysis was that after the diagnosis of SLE. SLE diagnosis was previous to CVD. Two groups matched by age and sex, 1:2 were formed. Results: a total of 1515 patients older than 18 years participated in the registry. Eighty patients with CVD (5.3%) were described in the registry. Two-hundred and forty patients were included, according to two groups. The mean age was 47.8 (SD 14.4) and 47.6 (SD 14.2) in patients with and without CVD, respectively. Patients with CVD had a longer duration of SLE in months, a higher Charlson index, a higher SLICC, increased frequency of neurological manifestations, antiphospholipid syndrome, hospitalizations, and use of cyclophosphamide. The associated variables in the multivariate were the Charlson Index (p=0.004) and the SLICC (p<0.001). Conclusions: CVDs have a significant influence on our patients, being associated with a greater possibility of damage and comorbidities.

Background: Anaemia is prevalent among cases with acute coronary syndrome (ACS) and has been linked to poor clinical prognosis. Guidelines for cases with ST-segment elevation myocardial infarction (STEMI) recommend timely primary percutaneous coronary intervention (pPCI) as the preferred reperfusion strategy. If timely pPCI cannot be performed, a pharmacoinvasive strategy (PI) is recommended within 12 hours of symptom onset. The aim of this work was to study and assess the impact of hemoglobin level as a predictor of MACE and short-term outcomes in cases treated with Primary PCI vs pharmacoinvasive strategy. Methods: This prospective case-control observational study was conducted on 100 cases that were divided into 2 groups. Group I consisted of 50 anaemic cases & group II consisted of 50 cases that were not anaemic. Both groups were subdivided into A subgroups that underwent revascularization by pPCI and B subgroups that underwent revascularization by pharmacoinvasive strategy. Results: There was no significant difference in LVEF, infarct site and final TIMI flow, the anaemic groups showed statistically significant more total MACE than non-anaemic groups whether revascularized by pPCI or pharmacoinvasive strategy. As expected, anaemic cases tended to have higher bleeding complications especially those undergoing pharmacoinvasive strategy. The anaemic cases also were less likely to be discharged on RAAS and beta blockers. Conclusions: Anaemic cases whether revascularized with pPCI or pharmacoinvasive strategy tend to have higher incidence of MACE and major bleeding with no significant difference in mortality. There was no significant difference between LVEF between the study groups.
RESUMEN
Objective:To explore the risk stratification value of HEART score combined with cardiac troponin (cTn) in emergency patients with chest pain.Methods:A total of 11 583 patients with chest pain who visited the Emergency Department of Zhongshan Hospital Affiliated to Fudan University from January to December 2019 were retrospectively collected. Patients who unfinished 0 h high-sensitivity cardiac troponin T (hs-cTnT) or electrocardiogram diagnosed ST-segment elevation myocardial infarction (STEMI) or lost to follow-up were excluded, and 7 057 patients were finally included. The final diagnosis of chest pain and the occurrence of major adverse cardiovascular events within 6 mon (6 m MACEs) were followed up by telephone and medical history. The HEART score of each patient was calculated by two attending physicians, and the patients were divided into the low-risk group (0-3 points), intermediate-risk group (4-6 points) and high-risk group (7-10 points) according to the final score. The risk stratification performance and safety of HEART score were observed and analyzed. A total of 1 884 patients who completed serial hs-cTnT tests were divided into groups according to HEART score (≤3 as low-risk group) and HEART score combined with serial hs-cTnT pathway (HEART score ≤3 and two hs-cTnT measurements <0.03 ng/mL as the low-risk group). The sensitivity (SE), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) of each diagnostic method were calculated to compare the diagnostic performance of the two predictive values.Results:The patients were divided into 3 groups by HEART score : 2 765 (39.2%) patients in the low-risk group, 3 438 (48.7%) in the intermediate-risk group, and 854 (12.1%) in the high-risk group. The incidence of 6 m MACEs in each group was 1.2%, 18% and 55.3%, respectively. When the low-risk threshold was 2, 23.1% of patients entered the low-risk group and the incidence of 6 m MACEs was 0.9%. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive performance of the HEART score for 6 m MACEs, and the final AUC was 0.831 ( P=0.006, 95% CI: 0.819-0.843). Regarding the occurrence of NSTEMI at the time of this visit, 4 (0.8%) patients were misdiagnosed by using the HEART score alone. Combined with serial troponin detection, the diagnostic SE and NPV were both 100%; at the same time, the diagnostic SE and NPV of 6 m MACEs in patients increased from 98.1% (95% CI: 96.9%-99.1%), 97.9% (95% CI: 96.2%-99%) to 99.1% (95% CI: 97.9%-99.7%) and 98.9% (95% CI: 97.4%-99.6%), the diagnosis SE and NPV of 6 m myocardial infarction and cardiac death in patients increased from 98% (95% CI: 96%-99.2%), 98.6% (95% CI: 97%-99.4%) to 99.2% (95% CI: 97.6%-99.8%) and 99.3% (95% CI: 98.1%-99.9%). Conclusions:The HEART score can be used for risk assessment in emergency patients with chest pain, and a threshold of 2 is recommended for the low-risk group. The diagnostic performance of HEART score combined with serial cTn is better than that of HEART score alone.
RESUMEN
Objective:To explore the prognostic evaluating value of serum tenascin-X in patients with acute ST-segment elevation myocardial infarction (STEMI).Methods:The clinical data of 121 patients with STEMI in the Affiliated Sinopharm Dongfeng General Hospital, Hubei University of Medicine from August 2017 to August 2018 were retrospectively analyzed. The clinical data were collected, the serum tenascin-X level was measured by enzyme-linked immunosorbent assay. The patients were followed up for 3 years, the major adverse cardiovascular events (MACE) were identified as endpoint events. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum tenascin-X for MACE in patients with STEMI. The Kaplan-Meier survival curve was drawn, the rates of non-MACE survival in patients with different serum tenascin-X levels were analyzed by log-rank method. Multivariate Cox regression was used to analyze the independent risk factors of MACE in patients with STEMI.Results:Until the end of follow-up, among 121 patients with STEMI, 42 cases (34.7%) developed MACE (MACE group), and 79 cases had not MACE (non-MACE group). The left ventricular ejection fraction (LVEF) in the MACE group was significantly lower than that in the non-MACE group: (47.14 ± 6.70)% vs. (52.67 ± 4.41)%, the C-reactive protein (CRP), B-type natriuretic peptide (BNP), cardiac troponin I (cTnI) and tenascin-X were significantly higher than those in non-MACE group: (27.92 ± 8.06) mg/L vs. (8.77 ± 3.49) mg/L, (918.31 ± 315.47) μg/L vs. (220.47 ± 108.37) μg/L, (214.73 ± 80.46) μg/L vs. (81.35 ± 28.96) μg/L and (110.67 ± 42.55) μg/L vs. (65.21 ± 28.06) μg/L, and there were statistical differences ( P<0.01). ROC curve analysis result showed that the area under the curve of serum tenascin-X to predict the MACE in patients with STEMI was 0.806 (95% CI 0.724 to 0.872), and the optimal cut-off was 93.25 μg/L, the sensitivity was 69.0%, the specificity was 86.1%. Kaplan-Meier survival curve analysis result showed that the rate of non-MACE in 80 patients with low serum tenascin-X level (<93.25 μg/L) was significantly higher than that in 41 patients with high serum tenascin-X level (≥93.25 μg/L): 83.8% vs. 29.3%, and there was statistical difference ( χ2 = 42.47, P<0.01). Multivariate Cox regression analysis result showed that the CRP, BNP and tenascin-X were the independent risk factors of MACE in patients with STEMI ( HR = 1.092, 1.001 and 1.018; 95% CI 1.051 to 1.135, 1.000 to 1.002 and 1.008 to 1.027; P<0.01 or <0.05). Conclusions:The significant increase in serum tendon protein X levels in patients with STEMI has predictive value for the MACE, and it is an independent predictor of MACE within 3 years.

After the treatment, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) in the observation group were lower than those in the control group: (128.42 ± 13.74) mmHg (1 mmHg = 0.133 kPa) vs. (134.98 ± 14.56) mmHg, (74.64 ± 8.02) mmHg vs.(78.25 ± 8.53) mmHg ( P<0.05); the BMI and WHR in the observation group were lower than those in the control group: (23.28 ± 1.66) kg/m 2 vs. (24.15 ± 2.02) kg/m 2, 0.84 ± 0.05 vs. 0.86 ± 0.03, P<0.05. The FRS score and 10-year incidence of CVD in the observation group were significantly lower than those in the control group: [(12.15 ± 1.52) scores vs.(12.84 ± 1.59) scores, (6.42 ± 1.52)% vs. (7.23 ± 1.79)%, P<0.05. Conclusions:The effect of resistance-aerobic exercise on PDM is obvious, which can significantly improve glycolipid metabolism and reduce the risk of CVD.
RESUMEN
Objective:To investigate the effect of the interaction between metabolic syndrome and smoking on the risk of subsequent cardiovascular events.Methods:Urban residents aged 40 and above in the Yunyan District of Guiyang City were selected from " Risk Evaluation of cAncers in Chinese diabeTic Individuals: A lONgitudinal(REACTION) Study". The baseline survey started in 2011 and general information including gender, age, medical history, lifestyle habits, and smoking status were collected. Additionally, biochemical indicators related to metabolic syndrome(MS) were measured. The study participants were then followed up, and the first cardiovascular events occurring after the initial survey were recorded. The average follow-up period was 10.07±1.49 years. The interaction between metabolic syndrome and smoking on subsequent cardiovascular events was analyzed using Cox proportional hazards models.Results:The study included a total of 7 275 individuals, among whom 639 experienced cardiovascular events. After adjusting for multiple variables, compared to non-smokers without metabolic syndrome(MS), smokers with MS showed a higher risk of cardiovascular events, with a hazard ratio( HR) of 6.54(95% CI 4.88, 8.78). This risk was higher than that of individuals with MS who never smoked [ HR 1.39(95% CI 1.11, 1.75)] and non-MS smokers [ HR 2.48(95% CI 1.77, 3.49)]. There was an additive interaction between MS and smoking on the occurrence of cardiovascular events, with a relative excess risk due to interaction(RERI) of 3.30(95% CI 1.89, 4.70), an attributable proportion(AP) of 0.55(95% CI 0.43, 0.59), and a synergy index(S) of 3.07(95% CI 1.94, 4.84). Furthermore, when stratifying the duration of smoking cessation, long-term quitters(≥8 years) showed a lower risk of cardiovascular events compared to current smokers, regardless of whether they had MS. The hazard ratios were 0.45(95% CI 0.26, 0.78) for individuals with MS and 0.42(95% CI 0.19, 0.95) for individuals without MS. Conclusions:There is an additive interaction between smoking and MS on the risk of cardiovascular events. The coexistence of both factors significantly increases the risk of cardiovascular events.
RESUMEN
Psoriasis is prone to be accompanied by cardiovascular diseases. Psoriasis and atherosclerosis have similar pathogenesis, involving the activation of innate immunity and autoreactive T cells. In recent years, more and more biological agents have been applied to systemic treatment of psoriasis, including tumor necrosis factor-α, interleukin-12/23 inhibitors and interleukin-17A inhibitors. The efficacy and safety of different biological agents, as well as their impact on cardiovascular diseases, have also attracted the attention of dermatologists. This review summarizes the common immunological pathogenesis of psoriasis and atherosclerosis, as well as the effects of different biological agents on cardiovascular diseases and related metabolic changes.
RESUMEN
Objective To investigate the effect of dapagliflozin on cardiac function and major adverse cardiac events(MACE)in elderly patients with heart failure after acute myocardial infarction.Methods The clinical data of 59 elderly patients with heart failure after acute myocardial infarction,treated in Liyuan Hospital,Tongji Medical College,Huazhong University of Science and Technology from May 2021 to February 2022,were collected and retrospectively analyzed.The objects were divided into control group(n=29)and dapagliflozin group(n=30)according to whether they took dapagliflozin during routine treatment.The cardiac function indexes[left vetricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD)]and the level of N-terminal pro-brain natriuretic peptide(NT-proBNP);as well as clinical total effective rate,Killip grading and MACE occurrence were detected and compared at discharge and within 6 months after discharge.Results At discharge and within 6 months'treatment,the levels of LVEF increased(P<0.05),and of LVEDD,LVESD and NT-proBNP decreased(P<0.05)in the two groups than those before treatment.The level of LVEF in the dapagliflozin group was higher(P<0.05),and the levels of LVEDD,LVESD and NT-proBNP were lower in dapagliflozin group(P<0.05)than those in control group.There was no statistical difference in the clinical total effective rate between the two groups(86.7%vs.65.5%,P>0.05)at discharge;The clinical total effective rate of dapagliflozin group was 93.3%,which was higher than control group of 62.1%within 6 months'treatment(P<0.05).Before treatment,at discharge and within 6 months'treatment,there was no statistical difference in the Killip classification between the two groups(P≥0.05).The incidence of MACE in dapagliflozin group was lower than that in control group within 6 months'treatment(P<0.05).Conclusion Compared with conventional anti heart failure therapy,combined with dapagliflozin can improve the cardiac function and prognosis,reduce the incidence of MACE of patients with heart failure after acute myocardial infarction.
RESUMEN
Objective To evaluate the long-term prognostic value of coronary CT angiography-derived fractional flow reserve(CT-FFR)in elderly patients with coronary heart disease(CHD).Methods A retrospective analysis was performed on 1133 patients with clinically suspected CHD from a prospective observational study based on coronary CTA and CT-FFR at the General Hos-pital of Eastern Theater from April 2018 to March 2019,and 330 elderly CHD patients were even-tually included.According to major adverse cardiovascular events(MACE)occurred or not,295 patients were assigned into non-MACE group and 35 patients into the MACE group.Based on cor-onary CTA data,plaque features were analyzed and CT-FFR values were measured in all lesioned vessels.The relationship of plaque features and CT-FFR with MACE was evaluated by using Cox proportional risk regression model,Kaplan-Meier survival curve,and ROC curve analyses.Results The patients with coronary stenosis(≥50％)or CT-FFR value ≤0.8 had a higher risk of MACE(P＜0.01).Univariate Cox analysis showed that coronary stenosis ≥50％and CT-FFR value 0.8 were risk factors of MACE(P＜0.01).After adjusting confounding factors,multivariate Cox analysis indicated that CT-FFR ≤0.8(HR=17.037,95％CI:5.060-57.358,P=0.000)was only independent predictor for MACE.The risk prediction model based on CT-FFR presented better performance than the model based on coronary CTA stenosis(C-index:0.820 vs 0.696,P=0.000).Conclusion CT-FFR≤0.8 is an important independent predictor for long-term MACE in elderly CHD patients.Clinical risk stratification based on CT-FFR may optimize prognostic man-agement strategies in these patients.
RESUMEN
INTRODUCTION@#Normal stress myocardial perfusion imaging (MPI) carries a favourable prognosis. Conversely, elevated coronary artery calcium (CAC) is associated with increased major adverse cardiovascular events (MACE). There is limited information on the prognosis and management of patients with elevated CAC and normal MPI. We aimed to assess the outcomes of patients with elevated CAC and normal MPI in relation to post-MPI statin use.@*METHODS@#A retrospective review of normal MPI with CAC score >300 was performed between 1 March 2016 and 31 January 2017 in a Singapore tertiary hospital. Patients with known atherosclerotic cardiovascular disease or left ventricular ejection fraction <50% on MPI were excluded. Patient demographics, prescriptions and MACE (cardiac death, nonfatal myocardial infarction and/or ischaemic stroke) at 24 months after MPI were traced using electronic records. Binary logistic regression was used to evaluate for independent predictors of MACE.@*RESULTS@#We included 311 patients (median age 71 years, 56.3% male), of whom 65.0% were on moderate to high-intensity statins (MHIS) after MPI. MACE was significantly lower in the post-MPI MHIS group (3.5% vs. 9.2%, P = 0.035). On univariate binary logistic regression, post-MPI MHIS use was the only significant predictor for MACE (odds ratio [OR] 0.355 [95% confidence interval (CI) 0.131-0.962], P = 0.042), even after multivariate adjustment (adjusted OR 0.363, 95% confidence interval 0.134-0.984, P = 0.046).@*CONCLUSION@#Post-MPI MHIS use is associated with lower MACE and is an independent negative predictor for 24-month MACE among patients with normal MPI and CAC >300.

Objective To investigate the predictive value of quantitative flow ratio(QFR)on the occurrence of major adverse cardiovascular events(MACE)3 years after percutaneous coronary intervention(PCI)in patients with non-acute myocardial infarction.Methods This study included 139 patients with non-acute myocardial infarction who underwent PCI from January 2020 to June 2020 in the cardiac catheterization room of our hospital,all of them underwent post-PCI target vessel QFR measurements,and the incidence of MACE was followed up 3 years after PCI.The cut-off value of QFR was calculated by receiver operating characteristic(ROC)curve,according to which patients were divided into QFR＞0.95 group and QFR≤0.95 group,and patients were divided into MACE group and non-MACE group depending on whether MACE occurs.The independent influencing factors of post-PCI QFR in patients with non-acute myocardial infarction were investigated by univariate and multifactorial linear regression analysis.Univariate and multivariate Cox regression analysis was used to investigate the predictive value of post-PCI QFR in the occurrence of MACE 3 years after PCI in patients with non-acute myocardial infarction.The long-term prognosis of patients with QFR＞0.95 and those with QFR≤0.95 was compared by drawing the survival curve of no-MACE event.Results ROC curve analysis showed that post-PCI QFR predicted the occurrence of MACE 3 years after surgery in non-acute myocardial infarction patients with statistical significance(AUC 0.666,95％CI 0.556-0.777,P=0.003),and the cut-off value of MACE was 0.95.The sensitivity and specificity were 75.00％and 51.30％for the diagnosis of MACE with QFR≤0.95.Patients were divided into QFR≤0.95 group(n=74)and QFR＞0.95 group(n=65)according to the cut-off value.Multivariate linear regression analysis showed that the maximum area stenosis rate after PCI was an independent factor for post-PCI QFR(P＜0.001).Multivariate Cox regression analysis showed that body mass index(BMI),post-PCI QFR,three-vessel lesions and post-PCI QFR groups were independent influencing factors of no-MACE lifetime.The no-MACE survival curve showed that the long-term prognosis of patients in the QFR＞0.95 group was significantly better than that in the QFR≤0.95 group(x2=5.272,P=0.022).Conclusions The optimal cut-off value of post-PCI QFR for predicting the occurrence of MACE 3 years after PCI in non-acute myocardial infarction patients was 0.95,and patients with QFR≤0.95 had worse long-term prognosis,and BMI,three-vessel lesions,and post-PCI QFR≤0.95 were independent risk factors for the occurrence of MACE 3 years in non-acute myocardial infarction patients after PCI.
RESUMEN
Objective:To investigate the relationship between preoperative left ventricular ejection fraction (LVEF) and the risk for postoperative major adverse cardiovascular events (MACE) in elderly patients with hip fracture.Methods:A retrospective study was conducted to analyze the data of 403 elderly patients with hip fracture who had undergone surgical treatment at Department of Orthopedics, Beijing Anzhen Hospital from January 2015 to January 2021. Gender: 118 males and 285 females; age: 80 (74, 85) years; fracture type: 228 femoral neck fractures and 175 intertrochanteric (including subtrochanteric) fractures. Cardiovascular disease was complicated in 161 patients before surgery. The incidence of MACE within 30 days after surgery was statistically analyzed. The patients were divided into 2 groups according to whether MACE occurred 30 days after surgery: an MACE group and a non-MACE group. The baseline data, LVEF, preoperative cardiovascular complications, American Society of Anesthesiologists(ASA) grading and other indicators were compared between the 2 groups. Based on patient sample analysis, the receiver operating characteristic curve (ROC) was plotted to determine the optimal cutoff value of preoperative LVEF, according to which the relationship was analyzed between preoperative LVEF and the risk for postoperative MACE.Results:The overall incidence of postoperative MACE was 12.4% (50/403). There were statistically significant differences between the MACE group and the non-MACE group in preoperative LVEF[60.0% (56.0%, 63.0%) versus 62.0% (60.0%, 65.0%)], preoperative cardiovascular complications[74.0% (37/50) versus 35.1% (124/353)] and ASA grade ≥3[90.0% (45/50) versus 74.8% (264/353)]. ROC analysis showed that LVEF=60% was the optimal threshold for prediction of postoperative MACE (area under curve=0.680, sensitivity 48.0%, and specificity 83.0%). Multivariate logistic regression analysis showed that LVEF<60% and preoperative cardiovascular disease were risk factors for postoperative MACE. Subgroup analysis showed that the incidence of MACE in patients with LVEF<60% was significantly higher than that in patients with LVEF≥60% regardless of preoperative cardiovascular disease ( P<0.05). Conclusion:Preoperative LVEF<60% is a risk factor for postoperative MACE in elderly patients with hip fracture.
