OBJECTIVE: To evaluate frailty and its relationship with prognostic markers in hospitalized patients with acute coronary syndrome. METHODS: This cross-sectional study with a prospective variable analysis (prognostic markers) involved adults of both sexes aged ≥ 50 years with acute coronary syndrome. Patients with ≥ 3 of the following criteria were considered frail: 1) unintentional weight loss; 2) exhaustion (assessed by self-reported fatigue); 3) low handgrip strength; 4) low physical activity level; and 5) low gait speed. The included prognostic markers were: metabolic changes (lipid and glycemic profile), changes in inflammatory status (C-reactive protein), thrombolysis in myocardial infarction risk score, troponin level, angioplasty or surgery, hospitalization in the intensive care unit, length of hospital stay, and hospital outcome. RESULTS: The sample consisted of 125 patients, whose mean age was 65.5 (SD, 8.7) years. The prevalence of frailty was 48.00%, which was higher in women (PR = 1.55; 95%CI 1.08­2.22; p = 0.018) and patients with systemic arterial hypertension (PR = 2.18; 95%CI 1.01­5.24; p = 0.030). Frailty was not associated with age, cardiac diagnosis, or prognostic markers (p > 0.05). CONCLUSIONS: Frailty was highly prevalent in patients with acute coronary syndrome, affecting almost half of the sample, particularly women and patients with hypertension, irrespective of age. However, despite its high prevalence, frailty was not associated with markers of metabolic change or poor prognosis.

Introduction: African countries are facing an epidemic of cardiovascular diseases. Information on the quality of acute coronary syndrome care offered in underserved communities in Ghana is limited. Using objective criteria, we examined the quality of acute coronary syndrome care offered to patients presenting to a tertiary referral center in Northern Ghana. Methods: we conducted a retrospective review of patients ≥ 18 years old with acute coronary syndrome managed in Tamale Teaching Hospital. We assessed in-hospital outcomes and the extent of compliance to key performance and quality indicators as contained in the 2017 American Heart Association/American College of Cardiology guideline for adults with myocardial infarction. Results: sixty-two (62) patients with a mean age of 56.0 ± 16.1 years were recruited. The median delay to presentation was 24 hours (IQR 15-96 hours). 33.9% had ST-elevation myocardial infarction, of which only 14.3% received reperfusion therapy. About three-quarters of patients received dual antiplatelet therapy at discharge, with fewer patients receiving recommended high-intensity statin therapy (65.5%) or beta-blockers (69.1%). Only 38.2% of patients had their left ventricular ejection fraction documented. No cardiac rehabilitation program existed. Risk stratification of patients with non-ST-elevation myocardial infarction or stress testing for conservatively managed patients was not part of routine practice. Conclusion: acute coronary syndrome management remains a challenging issue in Northern Ghana. Several gaps exist in the care quality, timeliness of interventions and rehabilitation of affected patients. There is an urgent need for measures to improve the delivery of acute coronary syndrome care alongside primary prevention strategies.

Introduction@#Red cell distribution width (RDW) is a parameter that is readily available as part of a standard complete blood count (CBC). Studies have shown that an elevated RDW is associated with increased cardiovascular events including acute coronary syndrome (ACS). This cross- sectional retrospective study was conducted to determine the association of RDW in patients with ACS admitted to Bataan General Hospital and Medical Center (BGHMC).@*Methods@#A cross-sectional study was performed in a 500-bed tertiary care hospital in Bataan, Philippines. The clinical medical records of patients with ACS were analyzed retrospectively. A total of 811 patients was admitted as cases of ACS from January 2017 to December 2019. Using Slovin’s formula, the computed sample size was 261 patients. However, only 205 cases were included in the study in accordance to the eligibility criteria. The baseline RDW were recorded from the CBC obtained upon admission of patients with ACS.@*Results@#Based on the data collected from January 2017 to December 2019 from patients admitted to BGHMC, there was no significant association between RDW and in-house morbidity and mortality and classification of ACS.@*Conclusions@#There were no significant association between RDW and in-house morbidity and mortality and classification of ACS. The authors recommend to conduct the study for a longer duration to have more population included and to include other parameters such as cardiac enzymes, electrocardiogram (ECG) changes and presence of co-morbidities.

Introducción: Aunque la incidencia general de infarto agudo de miocardio ha disminuido en muchos países desarrollados en las últimas décadas, aún genera números elevados de morbilidad y mortalidad en los de bajos ingresos; mostrando cifras mayores en tiempos de la pandemia por coronavirus. Objetivo: Caracterizar a pacientes con diagnóstico de infarto agudo de miocardio según variables clinicoepidemiológicas, ecocardiográficas y terapéuticas. Métodos: Se realizó una investigación descriptiva y retrospectiva, desde enero de 2018 hasta noviembre de 2022, de 263 pacientes con diagnóstico de infarto agudo de miocardio, atendidos en el Centro de Cardiología y Cirugía Cardiovascular de Santiago de Cuba. Entre las variables analizadas figuraron la edad, el sexo, la topografía del infarto, las complicaciones, las alteraciones ecocardiográficas y el tratamiento trombolítico. Resultados: En la serie predominaron el sexo masculino y el grupo etario menor o igual de 65 años. Se observó una mayor frecuencia del infarto en la topografía inferior (177, para 67,3 %); de estos afectados, 52,1 % tuvo complicaciones. Asimismo, la complicación de mayor frecuencia fue la fibrilación auricular paroxística, seguida del infarto de ventrículo derecho; mientras que la fracción de eyección menor de 45 %, el volumen de la aurícula izquierda y la motilidad parietal presentaron significación estadística. Conclusiones: Las características clinicoepidemiológicas, ecocardiográficas y terapéuticas de los pacientes con infarto agudo de miocardio en la provincia de Santiago de Cuba no difieren del contexto epidemiológico mundial.

Introduction: Although the general incidence of acute myocardial infarction has diminished in many developed countries in the last decades, it still generates high numbers of morbidity and mortality in those with low income; showing higher figures in times of coronavirus. Objective: To characterize patients with diagnosis of acute myocardial infarction according to clinical, epidemiological, echocardiographic and therapeutic variables. Methods: A descriptive and retrospective investigation was carried out from January, 2018 to November, 2022, of 835 patients with diagnosis of acute myocardial infarction, assisted in the Cardiology and Cardiovascular Surgery Center of Santiago de Cuba. Among the analyzed variables there were age, sex, topography of infarction, complications, echocardiographic disorders and thrombolytic treatment. Results: In the series there was a prevalence of the male sex and the 65 or less age group. A higher frequency of infarction in the lower topography (177, for 67.3 %) was observed; of these patients, 52.9 % had complications. Also, the complication of more frequency was the paroxysmal atrial fibrillation, followed by the infarction of the right ventricle; while the ejection fraction smaller than 45 %, the volume of the left auricle and the parietal motility presented statistical significance. Conclusions: Clinical, epidemiological, echocardiographic and therapeutic characteristics of patients with acute myocardial infarction in Santiago de Cuba province do not differ from the world epidemiological context.

Acute coronary syndrome (ACS),with increasing mortality year by year,has become a major public health problem in China.Exercise rehabilitation as an important part of the out-of-hospital rehabilitation for the patients with heart diseases can further reduce the mortality of patients on the basis of drug treatment.The available studies have proved that high-intensity interval training (HIIT) is more effective and efficient than moderate-intensity continuous training (MICT) such as walking and jogging on chronic cardiovascular diseases such as heart failure,stable coronary heart disease,and hypertension and has high security.According to the latest research,HIIT can reduce the platelet response,mitigate myocardial ischemia-reperfusion injury,and increase the exercise compliance of ACS patients more significantly than MICT.Moreover,it does not increase the risk of thrombotic adverse events or malignant arrhythmia.Therefore,HIIT is expected to become an important part of exercise prescription in out-of-hospital cardiac rehabilitation strategy for the patients with ACS.

Objective: To investigate the predictive value of glycosylated hemoglobin A1c/apolipoprotein A-1 (HbA1c/ApoA-1) ratio for major adverse cardiovascular events (MACEs) in patients with acute coronary syndrome (ACS). Methods: The present study is a retrospective cohort study. ACS patients who were hospitalized and underwent coronary angiography at Beijing Hospital from March 2017 to March 2019 were enrolled. Baseline information such as sex, age, previous history, Gensini score, HbA1c and ApoA-1 were analyzed. Patients were divided into two groups according to presence or absence of MACEs and the difference on HbA1c/ApoA-1 ratio was compared between the two groups. According to the tertiles of HbA1c/ApoA-1 levels, patients were divided into high (5.87-16.12), medium (4.50-5.83) and low (2.11-4.48) HbA1c/ApoA-1 groups. Cox proportional risk model was used to evaluate the differences in MACEs and all-cause mortality among the three groups. Kaplan-Meier survival analysis was used to compare the differences of MACEs between the various HbA1c/ApoA-1 groups. Results: A total of 366 ACS patients were included in this study. The mean age of the patients was (65.9±10.3) years. There were 59 MACEs and 10 all-cause deaths during the mean of (22.3±4.4) months follow-up. After adjusting for age, systolic blood pressure, history of diabetes and Gensini score, the incidence of MACEs was 2.45 times higher in the high HbA1c/ApoA-1 group than in the low HbA1c/ApoA-1 group (95%CI 1.16-5.18, P=0.019). There was no significant difference in all-cause mortality between the high and low HbA1c/ApoA-1 groups (P=1.000). Kaplan-Meier survival analysis showed that patients in the high HbA1c/ApoA-1 group had the highest risk of MACEs, while patients in the low HbA1c/ApoA-1 group had the lowest risk of MACEs (P<0.01). Spearman rank correlation analysis showed that HbA1/ApoA-1 ratio was positively correlated with Gensini score in ACS patients (r=0.274, P<0.01). Conclusion: High HbA1c/ApoA-1 ratio was an independent risk factor for MACEs in ACS patients. Patients with high HbA1c/ApoA-1 ratio had more severe coronary artery disease lesions. HbA1c/ApoA-1 ratio may be used as a potential risk stratification biomarker for ACS patients, it might be useful for the early identification of high-risk population and for predicting the incidence of MACEs among ACS patients.

Acute coronary syndrome (ACS) is one of the leading causes of death in cardiovascular disease. Percutaneous coronary intervention (PCI) is an important method for the treatment of coronary heart disease (CHD), and it has greatly reduced the mortality of ACS patients since its application. However, a series of new problems may occur after PCI, such as in-stent restenosis, no-reflow phenomenon, in-stent neoatherosclerosis, late stent thrombosis, myocardial ischemia-reperfusion injury, and malignant ventricular arrhythmias, which result in the occurrence of major adverse cardiac events (MACE) that seriously reduce the postoperative benefit for patients. The inflammatory response is a key mechanism of MACE after PCI. Therefore, examining effective anti-inflammatory therapies after PCI in patients with ACS is a current research focus to reduce the incidence of MACE. The pharmacological mechanism and clinical efficacy of routine Western medicine treatment for the anti-inflammatory treatment of CHD have been verified. Many Chinese medicine (CM) preparations have been widely used in the treatment of CHD. Basic and clinical studies showed that effectiveness of the combination of CM and Western medicine treatments in reducing incidence of MACE after PCI was better than Western medicine treatment alone. The current paper reviewed the potential mechanism of the inflammatory response and occurrence of MACE after PCI in patients with ACS and the research progress of combined Chinese and Western medicine treatments in reducing incidence of MACE. The results provide a theoretical basis for further research and clinical treatment.

Huangtu Decoction, first recorded in Essentials from the Golden Cabinet(Jin Kui Yao Lue) from ZHANG Zhong-jing in Han dynasty, is used to treat distal bleeding. It is mainly treated for the syndrome of failing to control blood with spleen-yang deficiency. The connotation of distal bleeding is more extensive, including not only upper gastrointestinal bleeding in the traditional sense such as peptic ulcer bleeding, gastrointestinal tumors, gastric mucosal lesions, vascular dysplasia, esophagogastric variceal bleeding, and pancreatic and biliary tract injury, but also other anorectal diseases such as part colon and rectal cancer swelling or polyps, hemorrhoids, and anal fissure and other parts of bleeding such as epistaxis, thrombocytopenia, functional uterine bleeding, threatened abortion, and unexplained hematuria. Distal bleeding also involves syndromes of failing to keep part deficient and cold fluids in interior, such as nocturia, enuresis, clear nose, sweating, cold tears, and leucorrhea, and excessive gastrointestinal bleeding caused by anti-plate and anticoagulant drugs, unexplained positive in the fecal occult blood test, and other modern clinical new problems. The indications of Huangtu Decoction include not only lower blood, defecation before blood, distant blood, hematemesis, epistaxis, and other diseases in traditional Chinese medicine, but also three types of clinical manifestations including bleeding, deficiency syndrome, and stagnant heat syndrome. In the clinic, Huangtu Decoction can be used to treat acute upper gastrointestinal bleeding, acute coronary syndrome complicated with acute upper gastrointestinal bleeding, bleeding events caused by excessive antiplatelet and anticoagulant drugs, unexplained positive in the fecal occult blood test, gastrointestinal tumor with bleeding, thrombocytopenia, and other acute and critical diseases. The dosage of Cooking Stove Earthkey, Rehmanniae Radix, and Asini Corii Colla in Huangtu Decoction is the key to hemostasis.

OBJECTIVE@#We aimed to assess the feasibility and superiority of machine learning (ML) methods to predict the risk of Major Adverse Cardiovascular Events (MACEs) in chest pain patients with NSTE-ACS.@*METHODS@#Enrolled chest pain patients were from two centers, Beijing Anzhen Emergency Chest Pain Center Beijing Bo'ai Hospital, China Rehabilitation Research Center. Five classifiers were used to develop ML models. Accuracy, Precision, Recall, F-Measure and AUC were used to assess the model performance and prediction effect compared with HEART risk scoring system. Ultimately, ML model constructed by Naïve Bayes was employed to predict the occurrence of MACEs.@*RESULTS@#According to learning metrics, ML models constructed by different classifiers were superior over HEART (History, ECG, Age, Risk factors, & Troponin) scoring system when predicting acute myocardial infarction (AMI) and all-cause death. However, according to ROC curves and AUC, ML model constructed by different classifiers performed better than HEART scoring system only in prediction for AMI. Among the five ML algorithms, Linear support vector machine (SVC), Naïve Bayes and Logistic regression classifiers stood out with all Accuracy, Precision, Recall and F-Measure from 0.8 to 1.0 for predicting any event, AMI, revascularization and all-cause death ( vs. HEART ≤ 0.78), with AUC from 0.88 to 0.98 for predicting any event, AMI and revascularization ( vs. HEART ≤ 0.85). ML model developed by Naïve Bayes predicted that suspected acute coronary syndrome (ACS), abnormal electrocardiogram (ECG), elevated hs-cTn I, sex and smoking were risk factors of MACEs.@*CONCLUSION@#Compared with HEART risk scoring system, the superiority of ML method was demonstrated when employing Linear SVC classifier, Naïve Bayes and Logistic. ML method could be a promising method to predict MACEs in chest pain patients with NSTE-ACS.

Objective: For patients with atrial fibrillation (AF) complicated with acute coronary syndrome (ACS), both anticoagulant and antiplatelet therapy should be applied, but the use of anticoagulation therapy is still poor in these patients in China. The purpose of this study was to explore the status and adherence of antithrombotic therapy in AF patients with ACS and the impact on 1 year clinical outcomes. Methods: Patients with AF hospitalized for ACS were retrospectively included from 6 tertiary hospitals in China between July 2015 and December 2020. According to the use of anticoagulant drugs at discharge, patients were divided into two groups: anticoagulant treatment group and non-anticoagulant treatment group. Logistic regression model was used to analyze the main factors influencing the use of anticoagulant drugs in patients with atrial fibrillation complicated with ACS. Major adverse cardiac events (MACEs) were defined as all-cause death, non-fatal myocardial infarction or coronary revascularization, and ischemic stroke and Bleeding Academic Research Consortium (BARC) 3 bleeding events were also collected at 1 year after discharge. After propensity score matching, Cox proportional hazards models and Kaplan-Meier analysis were used to evaluate the effect of anticoagulant treatment and non-anticoagulant treatment on 1-year prognosis. The patients were divided into different groups according to whether anticoagulation was performed at discharge and follow-up, and the sensitivity of the results was analyzed. Results: A total of 664 patients were enrolled, and 273 (41.1%) were treated with anticoagulant therapy, of whom 84 (30.8%) received triple antithrombotic therapy, 91 (33.3%) received double antithrombotic therapy (single antiplatelet combined with anticoagulant), and 98 (35.9%) received single anticoagulant therapy. Three hundred and ninety-one (58.9%) patients were treated with antiplatelet therapy, including 253 (64.7%) with dual antiplatelet therapy and 138 (35.3%) with single antiplatelet therapy. After 1∶1 propensity score matching between the anticoagulant group and the non-anticoagulant group, a total of 218 pairs were matched. Multivariate logistic regression analysis showed that history of diabetes, HAS-BLED score≥3, and percutaneous coronary intervention were predictors of the absence of anticoagulant therapy, while history of ischemic stroke and persistent atrial fibrillation were predictors of anticoagulant therapy. At 1-year follow-up, 218 patients (79.9%) in the anticoagulant group continued to receive anticoagulant therapy, and 333 patients (85.2%) in the antiplatelet group continued to receive antiplatelet therapy. At 1-year follow-up, 36 MACEs events (13.2%) occurred in the anticoagulant group, and 81 MACEs events (20.7%) in the non-anticoagulant group. HR values and confidence intervals were calculated by Cox proportional risk model. Patients in the non-anticoagulant group faced a higher risk of MACEs (HR=1.802, 95%CI 1.112-2.921, P=0.017), and the risk of bleeding events was similar between the two group (HR=0.825,95%CI 0.397-1.715, P=0.607). Conclusions: History of diabetes, HAS-BLED score≥3, and percutaneous coronary intervention are independent factors for the absence of anticoagulant therapy in patients with AF complicated with ACS. The incidence of MACEs, death and myocardial infarction is lower in the anticoagulant group, and the incidence of bleeding events is similar between the two groups. The risk of bleeding and ischemia/thrombosis should be dynamically assessed during follow-up and antithrombotic regiments should be adjusted accordingly.

Background@#Acute coronary syndrome (ACS) is a major cardiovascular problem due to its high hospitalization and mortality rates. One of the risk factors for atherosclerosis that leads to ACS is insulin resistance (IR) which plays a role in the pathogenesis and development of cardiovascular events. This study aims to determine the relationship between IR and in-hospital outcomes in non-diabetic patients with ACS.@*Methodology@#This was a cohort study conducted from January-June 2021. Insulin resistance was assessed using the Admission insulin resistance index (AIRI). This measurement was performed once during the patient's admission, and then the outcome was observed during hospitalization. The observed in-hospital outcomes were composite outcomes; namely, heart failure, arrhythmia, cardiogenic shock, and death. The statistical tests used were ANOVA, independent T and Chi-Square tests. Statistical test results were considered significant if p<0.05.@*Results@#This study included 60 subjects (51 males and 9 females). Analysis revealed that AIRI was higher in patients with composite outcomes (mean 9.97 ± 4.08) than in patients without composite outcomes (mean 7.71 ± 4.06) (p<0.05); AIRI was higher in patients with heart failure (mean 10.72 ± 3.83) than in patients without heart failure (mean 7.25 ± 3.84) (p<0.001). Patients with IR had a higher rate of heart failure complications [OR 5.5 95% CI (1.56-19.38) (p=0.005)].@*Conclusion@#There is an association between AIRI and composite outcomes. Patients with IR have 5.5 times the risk of developing heart failure.

Objetivo: Verificar aconduta do enfermeiro no atendimento ao paciente com síndrome coronariana aguda e identificar quais os cuidados de enfermagem realizados ao paciente em unidades de pronto atendimento.Métodos: Estudo qualitativo, exploratório, descritivo, organizado e guiado conforme o modelo de Design Instrucional Contextualizado, na etapa de análise. A coleta de dados ocorreu de janeiro a abril de 2019, em Unidade de Pronto Atendimento, por meio de entrevista semiestruturada com 19 enfermeiros de um município do litoral norte de Santa Catarina no sul do Brasil e os dados foram submetidos à análise temática. Resultados: Emergiram três categorias: "identificando sinais e sintomas da síndrome coronariana aguda", "definindo as condutas" e "proposta de cuidados de enfermagem". Os enfermeiros baseiam a avaliação nos sinais clínicos e sinais vitais e em suas experiências, destacam a realização do eletrocardiograma, restrição de esforço físico e preocupação com os cuidados realizados na sala de emergência até estabilização do caso, ou transferência para o hospital de referência. Conclusão: A conduta dos enfermeiros não segue um padrão de cuidados resultando na variação do atendimento. Foram propostos os cuidados e estes corroboram com a literatura e são primordiais no manejo aquedado da síndrome coronariana aguda na urgência e emergência. Descritores: Cuidados de Enfermagem.

Objective: To verify nurses' actions in the care of patients with acute coronary syndrome and to identify which Nursing care measures were applied to the patients in emergency care units. Methods: A qualitative, exploratory and descriptive study, organized and guided according to the Contextualized Instructional Design model, in the analysis stage. Data collection took place from January to April 2019 in an Emergency Care Unit, through semi-structured interviews with 19 nurses from a municipality on the North coast of Santa Catarina (southern Brazil) and the data were submitted to thematic analysis.Results: Three categories emerged, as follows: "Identifying signs and symptoms of acute coronary syndrome", "Definingthe courses of action" and "Proposal for Nursing care measures". Nurses base their evaluation on clinical and vital signs and on their experiences, highlight the performance of an electrocardiogram, restriction of physical efforts, and concern with the care measures performed in the emergency room until stabilization of the case or transfer to the reference hospital. Conclusion: The nurses' actions do not follow a care standard, resulting in variation of the care provided. Care measures were proposed that corroborate the literature and are paramount in adequate management of acute coronary syndrome in urgency and emergency services.Descriptors:Nursing Care. Nursing.

Antecedentes: En prevención secundaria cardiovascular, el control de los factores de riesgo es deficiente y la falta de adherencia terapéutica parece ser uno de los factores causales. El cumplimiento terapéutico se asocia a un 20% de disminución del riesgo de enfermedad cardiovascular y un 38% de disminución de mortalidad por cualquier causa. Sin embargo, la adherencia a los fármacos preventivos ronda el 50% al año después del alta hospitalaria, lo que multiplica por 3 el riesgo de mortalidad. Objetivos: Describir la adherencia a mediano plazo a tratamiento de prevención secundaria post síndrome coronario agudo de los pacientes adultos ingresados al Hospital Hernán Henríquez Aravena durante el año 2018. Determinar las características clínicas y sociodemográficas de la población y explorar las posibles causas asociadas a la falta de adherencia terapéutica en este grupo de pacientes. Métodos y Resultados: Se evaluaron 396 pacientes con síndrome coronario agudo en el Hospital Hernán Henríquez Aravena de Temuco durante el año 2018. La adherencia a terapia farmacológica se evaluó mediante el cuestionario de Morisky-Green de ocho ítems, aplicado vía telefónica. Se evaluó la asociación de variables clínicas y sociodemográficas con el nivel de adherencia mediante regresión ordinal y análisis de correspondencias. Resultados: Un 41.9% de los pacientes mantuvieron adherencia a la terapia a 2 años de seguimiento. Variables sociodemográficas como el bajo nivel educacional, la ruralidad, y la presencia de 1 o 2 apellidos mapuche se asociaron con baja adherencia a terapia farmacológica. Conclusión: La adherencia a medidas de prevención secundaria después del tratamiento por un síndrome coronario aguda es baja. Los principales factores relacionados a la falta de adherencia fueron el bajo nivel educacional y la ruralidad.

Background: a lack of therapeutic adherence to secondary prevention measures after acute coronary events leads to a poor control of risk factors. Adherence to treatment is associated with a reduction of 20% in the risk of cardiovascular disease and 38% reduction in all-cause mortality long term. However, adherence to drug therapy is about 50% a year after hospital discharge, which leads to an approximately three fold increase in mortality. Objectives: to describe the medium-term adherence to secondary prevention treatment following an acute coronary syndrome in adult patients admitted to a general hospital during 2018. In addition, to relate clinical and sociodemographic characteristics related to poor adherence and also to explore possible causes associated with the lack of therapeutic adherence in this group of patients. Methods: 396 patients treated for an acute coronary syndrome were followed after being discharged from the Hernán Henríquez Aravena Hospital in Temuco (Chile) during 2018. Adherence to pharmacological therapy was evaluated using the eight-item Morisky-Green questionnaire applied via phone call. The association of clinical and sociodemographic variables with the level of adherence was evaluated using ordinal regression and correspondence analysis. Results: Only 41.9% of patients maintained adherence to therapy at 2 years of follow-up. Low educational level, rurality, and the presence of 1 or 2 mapuche surnames were associated to poor adherence to drug therapy.

The persistent left superior vena cava is the most common venous anomaly in the systemic drainage in adults and tends to be asymptomatic. The persistent left superior vena cava causes rhythm disorders such as tachyarrhythmias or bradyarrhythmias. We report a case of persistent left superior vena cava diagnosed in a 53-year-old female patient admitted due to an acute coronary syndrome associated with unstable bradycardia. A transvenous peacemaker impressed the left atrium; therefore, a transthoracic echocardiogram was required to diagnose persistent left superior vena cava. The patient needed management with percutaneous intervention; she had an adequate evolution and subsequent discharge from the intensive care unit

La vena cava superior izquierda persistente es la anomalía venosa más frecuente en el drenaje sistémico en adultos; tiende a ser asintomática, pero causa trastornos del ritmo como taquiarritmias o bradiarritmias. Se presenta un caso de vena cava superior izquierda persistente diagnosticada en una paciente de 53 años hospitalizada por un síndrome coronario agudo asociado a bradicardia inestable. Un marcapasos transvenoso dejó una impresión en la aurícula izquierda, por lo que se requirió un ecocardiograma transtorácico para diagnosticar la vena cava superior izquierda persistente. La paciente necesitó una intervención percutánea con una adecuada evolución y se le dio el alta de la unidad de cuidados intensivos.

Abstract Background The neuropeptide Y (NPY) is one of the most abundant neurotransmitters in the nervous system. NPY acts as a potent stimulator of angiogenesis, inflammation, and adipogenesis, through the NPY 2 receptor (NPY2R). Changes in the NPY signaling pathway have been linked to Acute Coronary Syndrome (ACS). Objectives The purpose of this study is to determine the association between variants in the NPY and NPY2R genes, as well as the severity of acute coronary syndrome (ACS). Methods Approximately 221 ACS patients and 278 healthy controls were selected for this study. Four variants in NPY and two variants in NPY2R genes were genotyped using Taqman allelic discrimination and sequencing. The Chi-square and Fisher's exact tests were used to verify the genotype frequencies. The logistic regression analyses were used for the evaluation of the studied variables. Haplotype analysis was used to evaluate the linkage disequilibrium (LD) between the variants (p<0.05). Results An association of NPY c.20T>C variant was found with the ACS group when compared to the healthy group. In the analysis between variants and risk factors in the ACS group, NPY c.84G>A was associated with hypertension. The analysis between TIMI risk showed a significance for NPY c.20T>C between the low and intermediate/high TIMI risk groups. In the haplotype analysis, strong linkage disequilibrium (LD) was found between the variants NPY c.150G>A and NPY c.-485T>C. Conclusion The NPY c.20T>C variant appears to contribute to the development of ACS. The NPY2R c.-1116A>G variant may contribute to the early development of ACS and the NPY c.84G>A variant appears to contribute to the development of hypertension. In addition, the NPY c.20T>C is associated with a protective effect in ACS severity.
