Gastroplastia como medida terapêutica em pacientes obesos hipertensos / Gastroplastia as a therapeutic measure in obese hypertensive patients

A hipertensão arterial (HA) e a obesidade são doenças crônicas que se interrelacionam por meio de um quadro complexo de comunicação hormonal e uma série de cascatas enzimáticas. Isso faz com que o manejo dessas comorbidades seja complexo e multifatorial, muitas vezes levando a abandono ou falha terapêutica por parte de pacientes e profissionais de saúde, levando, então, às complicações dessas patologias. Há diversas formas de manejo e a gastroplastia, também conhecida como cirurgia bariátrica, é uma técnica cirúrgica que vem apresentando como alternativa satisfatória para o manejo terapêutico (AU).

Arterial hypertension (AH) and obesity are chronic diseases that are interrelated through a complex framework of hormonal communication and a series of enzymatic cascades. This makes the management of these comorbidities complex and multifactorial, often leading to treatment abandonment or failure by patients and health professionals, thus leading to complications of these pathologies. There are several forms of management and gastroplasty, also known as bariatric surgery, is a surgery that has been presented as a satisfactory alternative for therapeutic management (AU),

Guanxin Danshen Dripping Pills Improve Quality of Life and Cardiovascular Prognoses of CHD Patients after PCI with Anxiety or Depression (GLAD Study): A Randomized Double-Blind Placebo-Controlled Study / 中国结合医学杂志

OBJECTIVE@#To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).@*METHODS@#From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12.@*RESULTS@#In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred.@*CONCLUSIONS@#GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI.

Hyperhomocysteinemia as an Independent Risk Factor for Coronary Heart Disease. Comparison with Conventional Risk Factors / Hiper-homocisteinemia como fator de risco independente para doença coronariana: comparação com fatores de risco convencionais

Abstract The present study was designed to evaluate the strength of association of raised plasma homocysteine concentration as a risk factor for coronary heart disease independent of conventional risk factor. It was a case control study conducted at Punjab Institute of Cardiology Lahore. A total of 210 subjects aged 25 to 60 years comprising of 105 newly admitted patients of CHD as cases and 105 age and sex matched healthy individuals with no history of CHD as control were recruited for the study. Fasting blood samples were obtained from cases and controls. Plasma homocysteine was analyzed by fluorescence polarization immunoassay (FPIA) method on automated immunoassay analyzer (Abbott IMX). Total cholesterol, triglyceride and HDL cholesterol were analyzed using calorimetric kit methods. The concentration of LDL cholesterol was calculated using Friedewald formula. The patients were also assessed for traditional risk factors such as age, sex, family history of CVD, hypertension, smoking and physical activity, and were compared with control subjects. The collected data was entered in SPSS version 24 for analysis and interpretation.The mean age in controls and experimental groups were 43.00± 8.42 years and 44.72± 8.59 years with statistically same distribution (p- value= 0.144). The mean plasma homocysteine for cases was 22.33± 9.22 µmol/L where as it was 12.59±3.73 µmol/L in control group. Highly significant difference was seen between the mean plasma level of homocysteine in cases and controls (p˂0.001).Simple logistic regression indicates a strong association of coronary heart disease with hyperhomocysteinemia (OR 7.45), which remained significantly associated with coronary heart disease by multivariate logistic regression (OR 7.10, 95%C1 3.12-12.83, p=0.000). The present study concludes that elevated levels of Plasma homocysteine is an independent risk factor for coronary heart disease independent of conventional risk factors and can be used as an indicator for predicting the future possibility for the onset of CVD.

Resumo O presente estudo foi desenhado para avaliar a força da associação da concentração elevada de homocisteína no plasma como um fator de risco para doença cardíaca coronária independente do fator de risco convencional.

Amostras de sangue em jejum foram obtidas de casos e controles. A homocisteína plasmática foi analisada pelo método de imunoensaio de polarização de fluorescência (FPIA) em analisador de imunoensaio automatizado (Abbott IMX). Colesterol total, triglicerídeos e colesterol HDL foram analisados ​​usando métodos de kit calorimétrico. A concentração de colesterol LDL foi calculada pela fórmula de Friedewald. Os pacientes também foram avaliados para fatores de risco tradicionais, como idade, sexo, história familiar de DCV, hipertensão, tabagismo e atividade física, e foram comparados com indivíduos de controle. Os dados coletados foram inseridos no SPSS versão 24 para análise e interpretação. A média de idade nos grupos controles e experimentais foi de 43,00 ± 8,42 anos e 44,72 ± 8,59 anos com distribuição estatisticamente igual (p-valor = 0,144). A homocisteína plasmática média para os casos foi de 22,33 ± 9,22 µmol / L, enquanto no grupo controle foi de 12,59 ± 3,73 µmol / L. Diferença altamente significativa foi observada entre o nível plasmático médio de homocisteína em casos e controles (p ˂ 0,001). A regressão logística simples indica uma forte associação de doença cardíaca coronária com hiper-homocisteinemia (OR 7,45), que permaneceu significativamente associada com doença cardíaca coronária por multivariada regressão logística (OR 7,10, 95% C1 3,12-12,83, p = 0,000). O presente estudo conclui que níveis elevados de homocisteína plasmática são fator de risco independente para doença cardíaca coronária, independentemente dos fatores de risco convencionais, e pode ser usado como um indicador para prever a possibilidade futura de aparecimento de DCV.

Self-reported quality of life in patients with coronary heart disease and analysis of the associated factors / 中华内科杂志

Objective: To investigate the quality of life and associated factors in patients with coronary heart disease (CHD) in China. Methods: A cross-sectional study of 25 provinces and cities in China was performed from June to September 2020. A questionnaire was used to collect the socio-demographic and clinical information of patients with CHD, while the European Five-dimensional Quality of Life Scale (EQ-5D) was used to assess the quality of life. Multiple linear regression model was performed to analyze the associated factors. Results: The median age of the 1 075 responders was 60 (52, 67) years, and 797 (74.1%) were men. The EQ-5D and EQ-VAS indices were 0.7 (0.5, 0.8) and 60.0 (40.0, 80.0). Among the five dimensions in the quality of life scale, the frequency of anxiety/depression was the highest (59.8%), while problems in self-care was the lowest (35.8%). In the multiple linear regression model, female, increasing age, obesity, comorbidity(ies), anxiety/depression, social media channels, and receiving the CABG therapy were associated with the lower EQ-5D index (all P<0.05). In addition, increasing age, obesity, comorbidity (ies), depression, anxiety and depression, social media channels, and receiving the CABG therapy were associated with lower EQ-VAS index (all P<0.05). Conclusion: Over half of the patients with CHD in China have a low quality of life, which is related to gender, age, obesity, treatment pathway, the presence or absence of comorbidity (ies), and psychological state. In addition to managing the adverse effects of traditional socio-demographic factors on the quality of life, clinical practices should pay attention to the psychological state of patients. Moreover, establishing a WeChat group for doctor-patient communication could improve the quality of life of CHD patients.

Isolation and quantification of a 17-epi-dammarane triterpenoid rhuslactone from roots of Rhus chinensis and its preventive effects on coronary heart disease and thrombosis in zebrafish / 中国中药杂志

Based on mass spectrometry(MS)-guided separation strategy, compound 1 was obtained from the roots of Rhus chinensis. By comprehensive analysis of high resolution-electrospray ionization-mass spectrometry(HR-ESI-MS), nuclear magnetic resonance(NMR) data, and quantum chemical calculation of NMR(qcc-NMR) parameters, compound 1 was elucidated as rhuslactone, a 17-epi-dammarane triterpenoid with a rare 17α-side chain. An HPLC-ELSD method for its quantification in R. chinensis was established and adopted for the quantification of rhuslactone in different batches of R. chinensis. Rhuslactone displayed a good linear relationship within the range of 0.021 3-1.07 μmol·mL~(-1 )(r=0.997 6), and the average recovery was 99.34% [relative standard deviation(RSD) 2.9%). Moreover, the results of the evaluation test of the preventive effects of rhusalctone on coronary heart disease(CHD) and thrombosis showed that rhuslactone(0.11 nmol·mL~(-1)) significantly alleviated heart enlargement and venous congestion and increased cardiac output(CO), blood flow velocity(BFV), and heart rate, thereby reducing thrombus formation in zebrafish with CHD. The effects of rhuslactone on CO and BFV were superior to that of digoxin(1.02 nmol·mL~(-1)), and its effect on improving heart rate was comparable to that of digoxin. This study provides experimental references for the isolation, identification, quality control, and application of rhuslactone from R. chinensis against CHD. It is worth mentioning that this study has discussed some omissions in the determination of the stereochemistry of C-17 in dammarane triterpenoids in the present coursebook Chemistry of Chinese Medicine and some research papers, that is, the compound may be 17-epi-dammarane triterpenoid. This paper has also proposed steps for the establishment of C-17 stereochemistry.

Research advances in mechanism of lipid infiltration of coronary heart disease and simultaneous treatment of phlegm and blood stasis based on phlegm-blood stasis correlation theory / 中国中药杂志

Atherosclerosis(AS) is the key pathological basis of coronary heart disease(CHD), and lipid infiltration is a classical theory to explain the pathological mechanism of AS. The theory highlights that the occurrence and development of AS are closely related to abnormal lipid metabolism, with the essence of the pathological reaction caused by the invasion of lipids into arterial intima from plasma. Phlegm and blood stasis are physiologically homologous and subject to pathological co-existence. Phlegm-blood stasis correlation is the basic theory to explain the pathogenesis characteristics of CHD and has important guiding significance for revealing the mecha-nism of lipid infiltration of CHD. Phlegm is the pathological product of abnormal metabolism of Qi, blood, and body fluid, and a gene-ral summary of a series of abnormally expressed lipid substances. Among them, turbid phlegm invades the heart vessels, gradually accumulates, and condenses to achieve the qualitative change from "invisible pathogen" to "tangible pathogen", which corresponds to the mechanism of lipid migration and deposition in the intima of blood vessels, and is the starting factor of the disease. Blood stasis is the continuous development of phlegm, and it is a result of pathological states such as decreased blood fluidity, increased blood coagulation, and abnormal rheology. The fact that blood stasis caused by phlegm accords with the pathological process of "lipid abnormality-circulatory disturbance" and is the central link of the disease. Phlegm and blood stasis aggravate each other and lead to indissoluble cementation. The phlegm-blood stasis combination serves as common pathogen to trigger the disease, which is the inevitable outcome of the disease. Based on the phlegm-blood stasis correlation theory, the simultaneous treatment of phlegm and blood stasis is established. It is found that this therapy can simultaneously regulate blood lipid, reduce blood viscosity, and improve blood circulation, which can fundamentally cut off the biological material basis of the reciprocal transformation between phlegm and blood stasis, thus exerting a significant curative effect.

Meta-analysis and GRADE evaluation of Guanxinning Tablets in treatment of angina pectoris of coronary heart disease / 中国中药杂志

This study aims to evaluate the efficacy and safety of Guanxinning Tablets+conventional western medicine in the treatment of angina pectoris of coronary heart disease, and provide evidence-based references for clinical medication. Retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, randomized controlled trial(RCT) about Guanxinning Tablets for the treatment of angina pectoris of coronary heart disease from the inception to April 2022 were collected. After literature screening and data extraction, the bias risk assessment tool recommended by the Cochrane evaluation manual handbook 5.1.0 was used to evaluate the quality of the included literature, and RevMan 5.3 and Stata 14.0 were used for Meta-analysis. Eighteen RCTs were finally included, involving 2 281 patients. Meta-analysis showed that, compared with conventional western medicine treatment alone, Guanxinning Tablets+conventional western medicine significantly improved angina pectoris efficacy(RR=1.33, 95%CI[1.13, 1.57], P=0.000 8), electrocardiogram efficacy(RR=1.32, 95%CI[1.02, 1.71], P=0.03), and exercise duration(MD=59.53, 95%CI[39.16, 79.90], P<0.000 01) and reduced the incidence of cardiovascular events(MACE)(RR=0.43, 95%CI[0.30, 0.61], P<0.000 01), high sensitivity C-reactive protein(hs-CRP)(MD=-2.75, 95%CI[-3.71,-1.79], P<0.000 01), and endothelin-1(ET-1) levels(MD=-9.34, 95%CI[-11.36,-7.32], P<0.000 01). There was no statistically significant difference in the incidence of adverse reactions between two groups(RR=0.91, 95%CI[0.68, 1.22], P=0.52). Subgroup analysis showed that Guanxinning Tablets may have better short-term efficacy(less than 6 months) in the treatment of heart-blood stasis syndrome. GRADE grading showed that angina pectoris efficacy, electrocardiogram efficacy, MACE, and ET-1 were in the medium grade, hs-CRP and adverse reactions were in the low grade, and exercise duration was in the extremely low grade. In conclusion, the efficacy of Guanxinning Tablets+conventional western medicine is better than conventional western medicine treatment alone, with good safety. Therefore, it is recommended for the short-term treatment of patients with heart-blood stasis syndrome. However, the evidence quality of some results is low, and more rigo-rous RCT is still needed to enhance the reliability of evidence.

Anti-inflammatory Therapy Progress in Major Adverse Cardiac Events after PCI: Chinese and Western Medicine / 中国结合医学杂志

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.

Correlation of mitochondrial tRNA variants with coronary heart disease in a Chinese pedigree / 中华医学遗传学杂志

OBJECTIVE@#To explore the correlation of mitochondrial DNA (mtDNA) variants and coronary heart disease (CHD) in a Chinese pedigree and the possible molecular mechanisms.@*METHODS@#A Chinese pedigree featuring matrilineal inheritance of CHD who visited Hangzhou First People's Hospital in May 2022 was selected as the study subject. Clinical data of the proband and her affected relatives was collected. By sequencing the mtDNA of the proband and her pedigree members, candidate variants were identified through comparison with wild type mitochondrial genes. Conservative analysis among various species was conducted, and bioinformatics software was used to predict the impact of variants on the secondary structure of tRNA. Real-time PCR was carried out to determine the copy number of mtDNA, and a transmitochondrial cell line was established for analyzing the mitochondrial functions, including membrane potential and ATP level.@*RESULTS@#This pedigree had contained thirty-two members from four generations. Among ten maternal members, four had CHD, which yielded a penetrance rate of 40%. Sequence analysis of proband and her matrilineal relatives revealed the presence of a novel m.4420A>T variant and a m.10463T>C variant, both of which were highly conserved among various species. Structurally, the m.4420A>T variant had occurred at position 22 in the D-arm of tRNAMet, which disrupted the 13T-22A base-pairing, while the m.10463T>C variant was located at position 67 in the acceptor arm of tRNAArg, a position critical for steady-state level of the tRNA. Functional analysis revealed that patients with the m.4420A>T and m.10463T>C variants exhibited much fewer copy number of mtDNA and lower mitochondrial membrane potential (MMP) and ATP contents (P < 0.05), which were decreased by approximately 50.47%, 39.6% and 47.4%, respectively.@*CONCLUSION@#Mitochondrial tRNAMet 4420A>T and tRNAArg 10463T>C variants may underlay the maternally transmitted CHD in this pedigree, which had shown variation in mtDNA homogeneity, age of onset, clinical phenotype and other differences, suggesting that nuclear genes, environmental factors and mitochondrial genetic background have certain influence on the pathogenesis of CHD.

Integrated strategy for biomarkers of stable coronary heart disease with phlegm and blood stasis syndrome based on RNA-seq and network pharmacology / 中国中药杂志

This study aimed to analyze the biological foundation and biomarkers of stable coronary heart disease(CHD) with phlegm and blood stasis(PBS) syndrome based on RNA-seq and network pharmacology. Peripheral blood nucleated cells from five CHD patients with PBS syndrome, five CHD patients with non-PBS syndrome, and five healthy adults were collected for RNA-seq. The specific targets of CHD with PBS syndrome were determined by differential gene expression analysis and Venn diagram analysis. The active ingredients of Danlou Tablets were screened out from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, and the "component-target" prediction was completed through PubChem and SwissTargetPrediction. The "drug-ingredient-target-signaling pathway" network of Danlou Tablets against CHD with PBS syndrome was optimized by Cytoscape software. After the target biomarkers were identified, 90 participants were enrolled for diagnostic tests, and 30 CHD patients with PBS syndrome were included in before-and-after experiment to determine the therapeutic effect of Danlou Tablets on those targets. As revealed by RNA-seq and Venn diagram analysis, 200 specific genes were identified for CHD with PBS syndrome. A total of 1 118 potential therapeutic targets of Danlou Tablets were predicted through network pharmacology. Through integrated analysis of the two gene sets, 13 key targets of Danlou Tablets in the treatment of CHD with PBS syndrome were screened out, including CSF1, AKR1C2, PDGFRB, ARG1, CNR2, ALOX15B, ALDH1A1, CTSL, PLA2G7, LAP3, AKR1C3, IGFBP3, and CA1. They were presumably the biomarkers of CHD with PBS syndrome. The ELISA test further showed that CSF1 was significantly up-regulated in the peripheral blood of CHD patients with PBS syndrome, and was significantly down-regulated after Danlou Tablets intervention. CSF1 may be a biomarker for CHD with PBS syndrome, and it is positively correlated with the severity of the disease. The diagnostic cut-off of CSF1 for CHD with PBS syndrome was 286 pg·mL~(-1).

Adherencia a tratamiento de prevención secundaria post síndrome coronario agudo, en pacientes adultos ingresados al Hospital Hernán Henríquez Aravena / Adherence to secondary prevention after acute coronary syndromes: experience in a chilean general hospital

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.

Tumor fibroso solitario de mediastino anterior adherido a pericardio. Reporte de un caso / Solitary fibrous tumor of anterior mediastinum adhered to pericardium. A case report

Se presenta el caso de un paciente de 82 años, con tumor intratorácico de crecimiento rápido, con aumento progresivo de la disnea, antecedentes de enfermedad coronaria y baja función cardíaca, obesidad y síndrome de apnea de sueño, quien fue sometido a toracotomía y a quien se le diagnosticó un tumor solitario fibroso de la pleura, tumor de muy baja frecuencia, adherido en forma sésil al pericardio, lo cual lo hace aún menos frecuente. Se hace una revisión general de las posibilidades terapéuticas, el diagnóstico histológico y por inmunohistoquímica, así como los criterios de benignidad y malignidad para este tipo de tumor, que son en su mayoría de buen pronóstico.

We present the case of an 82-year-old patient with a rapidly growing intrathoracic tumor, progressive increase in dyspnea, and a history of coronary heart disease and low cardiac function, obesity, and sleep apnea syndrome, who underwent thoracotomy and who was diagnosed with a Solitary Fibrous Tumor of the Pleura, a very low frequency tumor, adhered in sessile form to the pericardium, which makes it even less frequent. A general review is made of the therapeutic possibilities, the histological and immunohistochemical diagnosis, as well as the criteria of benignity and malignancy for this type of tumor, most of which have a good prognosis.

Conciencia de enfermedad cardiovascular y conocimiento sobre factores de riesgo y prevención cardiovascular: resultados chilenos de encuesta SIAC cono sur / Awareness of risk factors and prevention of cardiovascular disease in chile: SIAC cono sur survey

Resumen La conciencia de la enfermedad cardiovascular (ECV) en mujeres es crucial para prevenir futuros eventos cardiovasculares. En Chile, la percepción sobre ECV es baja. Objetivo: Actualizar el grado de conocimiento de las chilenas sobre ECV. Método: Estudio de corte transversal realizado a través de encuesta online a mujeres entre 20 y 70 años de edad, residentes en Chile durante marzo 2020. La invitación se efectuó a través de redes sociales. La muestra fue no probabilística, ponderándose por edad, nivel socioeconómico y región de residencia (Región Metropolitana, Coquimbo, Valparaíso, Bío-Bío). Resultados: Se obtuvieron 1227 cuestionarios validados. La muestra ponderada correspondió a 900 mujeres. La percepción de ECV como principal causa de muerte fue de 8%, menor que las correspondientes a cáncer de mama (44%) y muerte violenta / homicidio (20%). Como principal problema de salud, la opción más percibida fue cáncer general (39%), seguido de diabetes (18%). Sólo 6 % refirió la ECV como el principal problema. Los principales accesos a la información sobre ECV fueron la internet y las redes sociales (64%, mayor en <30 años), y en el consultorio (32%). La opresión o dolor en el pecho fueron los síntomas más reconocidos asociados al infarto, siendo más seleccionado por mujeres con nivel educacional alto (p< 0.05). Conclusión: Persiste una baja percepción del riesgo de la ECV como principal causa de muerte y problema de salud en mujeres chilenas, aunque tienen acceso a la información y reconocen síntomas de infarto. Es necesario adaptar las estrategias comunicacionales para incrementar la percepción de riesgo CV.

Abstract Awareness of cardiovascular disease (CVD) in women is crucial to prevent cardiovascular events. According to prior information the perception and knowledge about CVD in Chile is extremely low. The aim of this study was to update the information about awareness of CVD in Chilean women. Method: Cross-sectional study carried out through an online survey. Data was obtained from women between 20 and 70 years old during March 2020. Social networks were used to recruit participants. The sample was non-probabilistic, weighted by age, socio-economic level and region of residence (Metropolitan Region, Coquimbo, Valparaíso, Bío-Bío). Results: 1227 validated surveys were obtained. The weighted sample corresponded to 900 women. CVD was perceived as the main cause of death in 8% of women, compared to higher degrees of perception for breast cancer (44%) and violent death/homicide (20%). CVD was perceived as the main health problem by only 6% of women, compared to cancer (39%) and diabetes (18%). The primary source of information about CVD were the internet and social networks (64%,higher in women <30 years old), and the doctor's office (32%). Chest tightness or pain as symptoms associated with a heart attack were significantly more recognized by respondents with a high educational level (p<0.05). Conclusion: An extremely low awareness about CVD as the main cause of death and health problem is persistent in Chilean women, notwithstanding that they have access to information and recognize symptoms of a heart attack. It is necessary to modify our communication strategies to increase the perception of CV risk in Chilean women.

Acute Myocardial Infarction and Percutaneous Coronary Intervention: What does the Epidemiological Data of the Last Years Indicate?

Abstract Background: ST-segment elevation acute myocardial infarction (STEMI) is a pathological process that involves cardiac muscle tissue death. Intravenous thrombolysis with fibrinolytics or primary percutaneous coronary intervention (PCI), an invasive technique, can be performed for tissue revascularization. PCI has been preferred as compared to non-invasive methods, although few studies have described its use in Brazil. Objectives: The aim of the present study was to analyze data on the use of primary PCI and investigate the relevance of hospitalizations for the treatment of STEMI in the country. Methods: A descriptive, cross-sectional analysis of data from the Brazilian Unified Health system (SUS) Department of Informatics (DATASUS) from 2010 to 2019 was conducted. Results: Hospitalizations for STEMI represented 0.6% of all hospital admissions in Brazil in the analyzed period, 0.9% of hospital costs, and 2.1% of deaths. The number of hospitalizations due to STEMI was 659,811, and 82,793 for PCIs. Length of hospital stay was 36.0% shorter and mortality rate was 53.3% lower in PCI. The mean cost of PCI was 3.5-fold higher than for treatment of STEMI. Conclusions: Data on hospitalizations for STEMI treatment in Brazil revealed high hospitalization and mortality rates, elevated costs, and long hospital stay. Although primary PCI is a more expensive and less used technique than other methods, it can reduce the length of hospital stay and mortality in the treatment of STEMI.

¿Es seguro el ácido tranexámico en la cirugía de reemplazo total de rodilla de pacientes con enfermedad coronaria? / Is tranexamic acid safe in total knee replacement surgery in patients with coronary artery disease?

Introducción: El ácido tranexámico reduce la pérdida sanguínea y los requerimientos de transfusiones luego de un reemplazo total de rodilla. Una de sus contraindicaciones relativas son los antecedentes de colocación de prótesis intravasculares coronarias, por un supuesto aumento de eventos tromboembólicos. materiales y métodos:Análisis retrospectivo de pacientes sometidos a un reemplazo total de rodilla primario y de revisión que recibieron ácido tranexámico y tenían antecedente de colocación de prótesis intravascular coronaria. Se los comparó con un grupo sin estas prótesis. Se analizó la presencia de cualquier cambio clínico o electrocardiográfico de oclusión coronaria aguda, eventos tromboembólicos, el requerimiento de transfusión sanguínea y el nivel de hemoglobina pre y posoperatorio. Resultados: 57 pacientes (59 cirugías, 56 reemplazos primarios y 3 revisiones) con colocación de prótesis intravascular coronaria, al menos, un año antes de la artroplastia. Un paciente tuvo síntomas de síndrome coronario agudo y cambios en el electrocardiograma. No hubo diferencias en la cantidad de eventos tromboembólicos. Solo un paciente del grupo de control recibió una transfusión de glóbulos rojos. El sangrado relativo fue menor en el grupo coronario independientemente del uso crónico de aspirina y clopidogrel antes de la cirugía (2,09 vs. 3,06 grupo de control; p = 0,01). En pacientes del alto riesgo, el ácido tranexámico no se asoció con más eventos tromboembólicos. Conclusiones: El ácido tranexámico impresionó ser seguro y efectivo en nuestro grupo de pacientes con prótesis intravasculares coronarias; sin embargo, se necesita un estudio prospectivo con más casos para confirmar estos resultados. Nivel de Evidencia: IV

Introduction: Tranexamic acid (TXA) reduces blood loss and need for a transfusion after total knee arthroplasty (TKA). However, patients with a history of coronary artery (CA) stent placement might be at increased risk for thromboembolic complications. Materials and methods: We performed a retrospective analysis of patients with a history of coronary stenting who had undergone primary and revision TKA and received preoperative TXA. A comparison was made with a group of patients without coronary stenting. The presence of any clinical or electrocardiographic changes of acute coronary occlusion, thromboembolic events (TEE), blood transfusion, and pre- and postoperative hemoglobin levels were analyzed. Results: 57 patients underwent 59 TKA surgeries (56 primary and 3 revisions) with a history of coronary stenting at least 1 year before arthroplasty. One patient presented symptoms of acute coronary syndrome and electrocardiogram (ECG) changes. There were no differences in the number of thromboembolic events. Only 1 patient received red blood cell transfusion in the control group. Relative bleeding was lower in the coronary group regardless of chronic use of aspirin and clopidogrel before surgery (2.09 vs 3.06 in the control group; p=0.01). In high-risk patients, TXA was not associated with higher TEEs. Conclusions: Although TXA seemed safe and effective in this database review of patients with previous placement of CAS; a larger prospective trial is warranted to confirm these results. Level of Evidence: IV

Correlation between Serum Homocysteine Level, MTHFR Gene Polymorphism and Patients with Hematological Diseases Complicated with Coronary Heart Disease / 中国实验血液学杂志

OBJECTIVE@#To observe the expression level of serum homocysteine (Hcy) and methylenetetrahydrofolate reductase (MTHFR) gene polymorphism in patients with hematological diseases complicated with coronary heart disease, and analyze the relationship between serum Hcy level, MTHFR gene polymorphism and coronary heart disease.@*METHODS@#The medical records of 80 patients with coronary heart disease who completed treatment of hematological diseases during the period from March 2018 to March 2020 were selected as observation group. In addition, the medical records of 92 patients with hematological diseases who completed treatment in our hospital during the same period were selected as control group. Venous blood samples of the two groups were collected to detect serum Hcy level and MTHFR gene polymorphism. The serum Hcy levels of the two groups with different MTHFR genotypes were compared, and the effects of the above indicators on hematological diseases complicated with coronary heart disease were analyzed.@*RESULTS@#The detection rates of MTHFR gene TT and TC in the observation group were higher than those in the control group, while the distribution frequency of MTHFR genotype CC was lower (P<0.05). The serum Hcy levels of the patients with MTHFR genotype TT and TC in the observation group was higher than the control group (P<0.05). Binary logistic regression analysis showed that MTHFR gene TC/CC genotype serum Hcy overexpression may be influencing factor which induced coronary heart disease in patients with hematological diseases (OR=2.107/OR=1.634, P<0.05). ROC curves showed that the AUC of serum Hcy level of MTHFR gene TC/CC genotype and hematological disease complicated with coronary heart disease were both > 0.8. When MTHFR gene TC reaching the optimal threshold of 22.165 μmol/L, the sensitivity was 0.950 and the specificity was 0.837, While MTHFR gene CC reached the optimal threshold of 19.630 μmol/L, the sensitivity was 0.938 and the specificity was 0.826, the best predictive value could be obtained.@*CONCLUSION@#The changes of serum Hcy and MTHFR gene polymorphisms may be involved in the pathological process in patients with hematological diseases complicated with coronary heart disease. In the future, early detection of serum Hcy levels and MTHFR gene polymorphisms in patients with hematological diseases can be used to predict the risk of coronary heart disease.

Evaluation of diagnostic efficacy of artery elasticity and endothelial function indexes for coronary heart disease with blood stasis syndrome in postmenopausal women by Logistic regression combined with ROC curve model / 中国中药杂志

The present study explored the correlation of coronary heart disease(CHD) with blood stasis syndrome in postmenopausal women with artery elasticity and endothelial function indexes and evaluated the diagnostic efficacy of the prediction model via logistic regression and receiver operating characteristic(ROC) curve model. A retrospective comparison was made between 366 postmenopausal CHD patients from August 1, 2020, to September 30, 2021, in the Department of Cardiology of Integrated Traditional Chinese and Western Medicine of China-Japan Friendship Hospital, who were divided into the blood stasis syndrome group(n=196) and the non-blood stasis syndrome group(n=170). General clinical characteristics of the two groups were compared. Multivariate logistic regression analysis was used to probe the correlation of CHD with blood stasis syndrome in postmenopausal women with brachial-ankle pulse wave velocity(baPWV), ankle-brachial index(ABI), and flow-mediated dilatation(FMD), and the ROC curve was drawn to evaluate the diagnostic efficiency of the prediction model. Multivariate logistic regression analysis showed that the correlation coefficients of CHD with blood stasis syndrome in postmenopausal women with baPWV, ABI, and FMD were 1.123, 0.109, and 0.719, respectively(P=0.004, P=0.005, P<0.001),and the regression equation for predicting probability P was P=1/[1+e~(-(3.131+0.116×baPWV-2.217×ABI-0.330×FMD))]. ROC curve analysis suggested that in the context of baPWV≥19.19 m·s~(-1) or ABI≤1.22 or FMD≤9.7%, it was of great significance to predict the diagnosis of CHD with blood stasis syndrome in postmenopausal women. The AUC of baPWV, ABI, FMD, and prediction probability P was 0.763, 0.607, 0.705, and 0.836, respectively. The AUC of prediction probability P was higher than that of each index alone(P<0.001), and the sensitivity and specificity were 0.888 and 0.647, respectively. The results demonstrate that baPWV, ABI, and FMD are independently correlated with CHD with blood stasis syndrome in postmenopausal women, and show certain independent predictive abilities(P<0.05). The combined evaluation of the three possesses the best diagnostic efficiency.
