ABSTRACT

Introducción: En numerosos estudios realizados en las últimas 3 décadas, se ha tratado de atribuir una relación causal a la enfermedad periodontal en la fisiopatología de la cardiopatía isquémica. Objetivo: Caracterizar el estado periodontal de pacientes con cardiopatía isquémica y algunos factores de riesgo cardiovascular. Métodos: Se realizó un estudio transversal de 50 pacientes, atendidos en la sala de cuidados coronarios del Hospital Provincial Vladimir Ilich Lenin de Holguín, desde septiembre de 2019 hasta enero de 2020. Se evaluó el estado periodontal mediante el Índice Periodontal de Russell simplificado. Se exploraron algunos factores de riesgo de la cardiopatía isquémica y se emplearon métodos teóricos, empíricos, así como la estadística descriptiva. Resultados: En la serie predominó el grupo de 60-69 años de edad (23 para 46,0 %); 56,0 % de los pacientes presentó infarto agudo de miocardio y 62,0 % periodontitis avanzada. Entre los factores de riesgo cardiovascular más frecuentes figuraron: hipertensión arterial (74,0 %) y tabaquismo (70,0 %). Conclusiones: En este estudio se halló, en gran medida, la periodontitis crónica en pacientes con cardiopatía isquémica, lo cual sirve de pauta para la toma de decisiones de médicos y estomatólogos.

ABSTRACT

The present study evaluated the curative efficacy of Chinese herbal injection on unstable angina pectoris( UAP) by network Meta-analysis. The databases,including Pub Med,Cochrane Library,Web of Science,CNKI,CBM,VIP and Wanfang were searched for randomized controlled trial( RCT) of Chinese herbal injection in the treatment of UAP. All researchers independently screened the articles,extracted the data and evaluated the quality. Open BUGS and Stata were employed for the analysis of the trials that met the quality standards. Fifty-eight studies were finally included in this study,involving 20 intervention measures. In terms of the effective rate,16 injections such as Dengzhan Xixin Injection,Xuesaitong Injection and Danshen Injection combined with western medicine exhibited significant efficacy. In terms of ECG,Puerarin Injection,Ginkgo Leaf Extract and Dipyridamole Injection( GDI),Breviscapine Injection combined with western medicine were superior to western medicine. In terms of the reduction of the angina attack times,Sodium Tanshinone ⅡASulfonate Injection,GDI and Dazhu Hongjingtian Injection combined with western medicine showed better effects than western medicine. In terms of shortening the angina duration,Shenmai Injection combined with western medicine was superior to western medicine. As revealed by the results,Dengzhan Xixin Injection,Xuesaitong Injection,Danshen Injection,Breviscapine Injection,Danshen Ligustrazine Injection combined with western medicine displayed prominent curative efficacy,which were recommended for clinical application. Meanwhile,appropriate intervention measures should be selected according to individual conditions. Limited by the quality of the included trials,the conclusions still need to be further verified.

ABSTRACT

OBJECTIVE@#To investigate the combined anti-inflammatory effect of activating blood circulation and detoxifying Chinese medicines in unstable angina (UA) patients.@*METHODS@#This study was an open-labeled, randomized controlled trial conducted in 5 centers in Beijing. A total of 154 patients were randomized into two groups at a 1:1 ratio by random numbers. Based on the conventional treatment, patients in the activating blood circulation (ABC) group were treated with Guanxin Danshen Droping Pill (, 0.4 g, thrice daily), and patients in the activating blood circulation and detoxifying (ABCD) group were treated with Guanxin Danshen Droping Pill (0.4 g, thrice daily) and Andrographis tablet (0.2 g, thrice daily) for 4 weeks. The primary outcome was the serum level of high sensitive C reaction protein (hs-CRP), and the secondary outcome index included the serum levels of tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), soluble CD40 ligand (sCD40L), thrombomodulin (TM), the score of angina pectoris, the score of blood stasis syndrome, and the score of Chinese medicine symptoms, observed at week 0 and week 4.@*RESULTS@#A total of 144 patients completed the trial (ABC group, n=70; ABCD group, n=74). There were no significant differences in the clinical baseline characteristics between the two groups. When compared with the ABC group, ABCD group showed better performance in reducing the level of inflammatory factors, especially hs-CRP (P<0.05), IL-6 (P<0.01) and TNF-α (P<0.01). In term of clinical symptoms, ABCD group played a better role in improving the scores of angina pectoris and blood stasis syndrome than ABC group (all P<0.05).@*CONCLUSIONS@#The combination of Guanxin Danshen Dropping Pill and Andrographis tablet exert significant anti-inflammatory effect on UA patients, which is superior to single Guanxin Danshen Dropping Pill.

ABSTRACT

OBJECTIVE@#To evaluate the effect of Danhong Injection (, DH) on the index of microcirculatory resistance (IMR) and myocardial injury in patients with unstable angina undergoing elective percutaneous coronary intervention (PCI).@*METHODS@#Seventy-eight patients with unstable angina were randomly divided into DH group (39 cases) and the control group (39 cases) during elective PCI. Randomization was performed using a random-number table. The DH group received DH at a dosage of 40 mL (mixed with 250 mL saline, covered by a light-proof bag, intravenous drip) during PCI and daily for 7 consecutive days, while the control group only received the same dosage of saline. Both groups received standardized treatment. The IMR and fractional flow reserve (FFR) were measured at maximal hyperemia before and after PCI. Myocardial markers, including myoglobin, creatine kinase (CK), creatine kinase MB (CK-MB), and coronary troponin T (cTnT) values were measured at baseline and 24 h after PCI.@*RESULTS@#Among the 78 patients enrolled, the baseline and procedural characteristics were similar between the two groups. There was no significant difference in pre-PCI myocardial markers and coronary physiological indexes between the two groups. However, post-PCI CK and CK-MB levels in the DH group were significantly lower than those in the control group (111.97 ± 80.97 vs. 165.47 ± 102.99, P=0.013; 13.08 ± 6.90 vs. 19.75 ± 15.49, P=0.016). Post-PCI myoglobin and cTNT-positive tend to be lower in the DH group than in the control group but did not reach statistical significance (88.07 ± 52.36 vs. 108.13 ± 90.94, P=0.52; 2.56% vs.7.69%, P=0.065). Compared with the control group, the post-IMR levels of the DH group tended to decrease, but there was no statistical difference (20.73 ± 13.15 vs. 26.37 ± 12.31, P=0.05). There were no statistical differences in post-FFR in both groups. The peri-procedural myocardial injury of the DH group was significantly lower than that of the control group (2.56% vs. 15.38%, P=0.025). During the 30-d follow-up period, no major adverse cardiovascular events occurred in either group.@*CONCLUSION@#This study demonstrated benefit of DH in reducing myocardial injury and potential preserving microvascular function in patients with unstable angina undergoing elective PCI.

ABSTRACT

Network Meta-analysis was used to compare the efficacy and safety of Chinese patent medicines in the treatment of unstable angina pectoris. PubMed, Cochrane Library, CNKI, Wanfang, VIP and other databases were retrieved by computers from the establishment of the databases to June 2020. Randomized controlled trials(RCTs) of Chinese patent medicines for the treatment of unstable angina pectoris were collected. Two investigators independently screened out the literatures, and extracted data according to the inclusion and exclusion criteria. The quality of the included RCTs was evaluated according to the bias risk assessment tool recommended by the Cochrane System Reviewer Manual, and the Stata 13.0 software was used for data analysis and mapping. Through screening, 28 eligible studies were finally included, with the sample size of 2 885 cases, involving 8 Chinese patent medicines. The results of the network Meta-analysis showed that in terms of total effective rate for angina symptom improvement, the order was as follows: Shenshao Capsules > Naoxintong Capsules > Ginkgo Ketone Ester Dripping Pills > Compound Danshen Dripping Pills > Ginkgo Leaf Tablets > Shexiang Baoxin Pills > Tongxinluo Capsules > Yindan Xinnaotong Soft Capsules; in terms of total effective rate for ECG curative effect, the order was as follows: Ginkgo Ketone Ester Dripping Pills>Compound Danshen Dripping Pills > Tongxinluo Capsules > Shenshao Capsules > Shexiang Baoxin Pills > Yindan Xinnaotong Soft Capsules; in terms of hypersensitivity-C-reactive protein curative effect, the order was as follows: Tongxinluo Capsules > Shenshao Capsules > Ginkgo Leaf Tablets>Compound Danshen Dropping Pills> Shexiang Baoxin Pills > Naoxintong Capsules > Yindan Xinnaotong Soft Capsules > Ginkgo Ketone Ester Dropping Pills. Chinese patent medicine combined with conventional therapy can improve the clinical efficacy of unstable angina pectoris. Due to the differences in the quantity and quality of the included studies, the order results of Chinese patent medicines need to be further verified.

ABSTRACT

Resumen Objetivo: establecer la prevalencia y la gravedad de la enfermedad periodontal en pacientes con síndrome coronario agudo sin comorbilidades, que ingresan al programa de rehabilitación cardíaca en la Fundación Clínica Shaio. Métodos: se examinaron 83 pacientes con diagnóstico de síndrome coronario agudo sin comorbilidades y los siguientes diagnósticos: angina inestable (n = 27), infarto de miocardio con elevación del segmento ST (STEMI) (n = 34) e infarto de miocardio sin elevación del segmento ST (NSTEMI) (n = 22). La prevalencia y la gravedad de la enfermedad periodontal fueron evaluadas con el índice periodontal de los Centros para el Control y la Prevención de Enfermedades (CDC). Se compararon entre los grupos índice clínico, placa, cálculo, hemorragia gingival, profundidad de sondaje y nivel de inserción clínica. Resultados: la prevalencia de enfermedad periodontal fue del 97,6% y se observó periodontitis avanzada en el 38,3%. Los pacientes con STEMI mostraron la mayor gravedad de la periodontitis. Los índices clínicos inflamatorios de la enfermedad periodontal se elevaron en todos los grupos sin diferencias significativas. El nivel de inserción clínica no mostró diferencias significativas entre las condiciones cardíacas. Sin embargo, se observó mayor porcentaje de sitios con pérdida de inserción clínica (PIC) ≥ 6 mm, y sitios con una profundidad de bolsas > 6 mm, en pacientes con STEMI. Conclusión: los pacientes con síndrome coronario agudo sin comorbilidades, que ingresaron al programa de rehabilitación cardíaca para completar su tratamiento, tuvieron alta prevalencia y gravedad de la enfermedad periodontal. Es necesario hacer énfasis en el control de la enfermedad periodontal en pacientes con enfermedad coronaria.


Abstract Objective: To determine the prevalence and severity of periodontal disease in patients with acute coronary syndrome with no comorbidities admitted to a cardiac rehabilitation programme in the Clínica Shaio Foundation, Colombia. Methods: The study included a total of 83 patients diagnosed with acute coronary syndrome with no comorbidities and the following diagnoses: unstable angina (n = 27), ST-segment elevation myocardial infarction (STEMI) (n = 34), and non-ST-elevation myocardial infarction (NSTEMI) (n = 22). The prevalence and severity of periodontal disease were evaluated using the Periodontal Index of the Centres for the Control and Prevention of Diseases. A between-group comparison was made of the clinical index, plaque, calculi, gingival bleeding, probing depth, and level of clinical attachment. Results: The prevalence of periodontal disease was 97.6%, and advance periodontitis was observed in 38.3% of subjects. The patients with a STEMI showed more severe periodontitis. The inflammatory clinical indices of periodontal disease were increased in all groups, with no significant differences being observed. There were no significant differences between clinical attachment and heart conditions. However, it was observed that there was a higher percentage of locations with a loss of clinical attachment ≥ 6 mm, and locations with bag depths > 6 mm in patients with a STEMI. Conclusión: The patients with acute coronary syndrome with no comorbidities, and who entered the cardiac rehabilitation programme to complete their treatment, had a high prevalence and severity of periodontal disease. The control of periodontal disease should be emphasised in patients with coronary disease..

ABSTRACT

BACKGROUND: Rapid and accurate diagnosis of acute myocardial infarction (AMI) is critical for initiating effective treatment and achieving better prognosis. We investigated the performance of copeptin for early diagnosis of AMI, in comparison with creatine kinase myocardial band (CK-MB) and troponin I (TnI). METHODS: We prospectively enrolled 271 patients presenting with chest pain (within six hours of onset), suggestive of acute coronary syndrome, at an emergency department (ED). Serum CK-MB, TnI, and copeptin levels were measured. The diagnostic performance of CK-MB, TnI, and copeptin, alone and in combination, for AMI was assessed by ROC curve analysis by comparing the area under the curve (AUC). Sensitivity, specificity, negative predictive value, and positive predictive value of each marker were obtained, and the characteristics of each marker were analyzed. RESULTS: The patients were diagnosed as having ST elevation myocardial infarction (STEMI; N=43), non-ST elevation myocardial infarction (NSTEMI; N=25), unstable angina (N=78), or other diseases (N=125). AUC comparisons showed copeptin had significantly better diagnostic performance than TnI in patients with chest pain within two hours of onset (AMI: P=0.022, ≤1 hour; STEMI: P=0.017, ≤1 hour and P=0.010, ≤2 hours). In addition, TnI and copeptin in combination exhibited significantly better diagnostic performance than CK-MB plus TnI in AMI and STEMI patients. CONCLUSIONS: The combination of TnI and copeptin improves AMI diagnostic performance in patients with early-onset chest pain in an ED setting.

ABSTRACT

The optimal dose of beta blockers after acute myocardial infarction (MI) remains uncertain. We evaluated the effectiveness of low-dose nebivolol, a beta1 blocker and a vasodilator, in patients with acute MI. A total of 625 patients with acute MI from 14 teaching hospitals in Korea were divided into 2 groups according to the dose of nebivolol (nebistol®, Elyson Pharmaceutical Co., Ltd., Seoul, Korea): low-dose group (1.25 mg daily, n=219) and usual- to high-dose group (≥2.5 mg daily, n=406). The primary endpoints were major adverse cardiac and cerebrovascular events (MACCE, composite of death from any cause, non-fatal MI, stroke, repeat revascularization, rehospitalization for unstable angina or heart failure) at 12 months. After adjustment using inverse probability of treatment weighting, the rates of MACCE were not different between the low-dose and the usual- to high-dose groups (2.8% and 3.1%, respectively; hazard ratio: 0.92, 95% confidence interval: 0.38 to 2.24, p=0.860). The low-dose nebivolol group showed higher rates of MI than the usual- to high-dose group (1.2% and 0%, p=0.008). The 2 groups had similar rates of death from any cause (1.1% and 0.3%, p=0.273), stroke (0.4% and 1.1%, p=0.384), repeat PCI (1.2% and 0.8%, p=0.428), rehospitalization for unstable angina (1.2% and 1.0%, p=0.743) and for heart failure (0.6% and 0.7%, p=0.832). In patients with acute MI, the rates of MACCE for low-dose and usual- to high-dose nebivolol were not significantly different at 12-month follow-up.

ABSTRACT

OBJECTIVES: High incidence and case fatality of unstable angina (UA) is, to a large extent, a consequence of the lack of highly sensitive and specific non-invasive markers. Circulating microRNAs (miRNAs) have been widely recommended as potential biomarkers for numerous diseases. In the present study, we characterized distinctive miRNA expression profiles in patients with stable angina (SA), UA, and normal coronary arteries (NCA), and identified promising candidates for UA diagnosis. METHODS: Serum was collected from patients with SA, UA, and NCA who visited the Department of Cardiovascular Diseases of the Meizhou People's Hospital. Small RNA sequencing was carried out on an Illumina HiSeq 2500 platform. miRNA expression in different groups of patients was profiled and then confirmed based on that in an independent set of patients. Functions of differentially expressed miRNAs were predicted using gene ontology classification and Kyoto Encyclopedia of Genes and Genomes pathway analysis. RESULTS: Our results indicated that circulating miRNA expression profiles differed between SA, UA, and NCA patients. A total of 36 and 161 miRNAs were dysregulated in SA and UA patients, respectively. miRNA expression was validated by reverse transcription quantitative polymerase chain reaction. CONCLUSION: The results suggest that circulating miRNAs are potential biomarkers of UA.

ABSTRACT

RESUMEN Introducción: El síndrome de Wellens es un patrón electrocardiográfico que se ha sugerido desde la década del 80 como indicador de obstrucción grave de la arteria descendente anterior, a pesar de ello es poco conocido y no se encuentra en las principales guías de tratamiento de los síndromes coronarios agudos. Objetivo: Demostrar la utilidad del diagnóstico del síndrome de Wellens como predictor de obstrucción grave de la descendente anterior. Método: Se realizó un estudio transversal con componente analítico, que abarcó a los 40 pacientes ingresados en la Unidad de Cuidados Coronarios Intensivos del Hospital Manuel Fajardo, en el período enero de 2016 hasta diciembre de 2017, con diagnóstico de síndrome coronario agudo sin elevación del segmento ST, a los que se les realizó coronariografía. Resultados: Se encontró la presencia de síndrome de Wellens en un 13,5% de los pacientes ingresados con este tipo de síndrome coronario agudo. La edad, el sexo y la presencia de comorbilidades no se relacionaron significativamente con la presencia de este síndrome. El estudio angiográfico evidenció, en los pacientes con un síndrome de Wellens, un riesgo relativo 3,4 veces mayor que el resto, de presentar una obstrucción grave de la arteria descendente anterior. Conclusiones: La identificación oportuna del síndrome de Wellens y su relación con una obstrucción coronaria grave deben motivar una estrategia intervencionista precoz en estos casos.


ABSTRACT Introduction: Wellens syndrome is an electrocardiographic pattern that has been suggested, since the 1980s, as indicator of severe obstruction of the left anterior descending artery, although it is poorly understood and it is not found in the main treatment guidelines for acute coronary syndromes. Objective: To demonstrate the usefulness of the diagnosis of Wellens syndrome as a predictor of severe obstruction of the left anterior descending artery. Method: A cross-sectional study with an analytical component was carried out, covering the 40 patients admitted to the Intensive Coronary Care Unit of the Hospital Manuel Fajardo, in the period from January 2016 to December 2017, with a diagnosis of non-ST-segment elevation acute coronary syndrome, who underwent coronary angiography. Results: The presence of Wellens syndrome was found in 13.5% of the patients admitted with this type of acute coronary syndrome. Age, sex and the presence of comorbidities were not significantly related to the presence of this syndrome. The angiographic study showed, in patients with a Wellens syndrome, a relative risk -3.4 times greater than the rest- of presenting a severe obstruction of the left anterior descending artery. Conclusions: The timely identification of Wellens syndrome and its relationship with a severe coronary obstruction should motivate an early interventionist strategy in these cases.

ABSTRACT

Myocardial revascularization surgery (MRS) is the most frequently performed cardiac surgery in Brazil. However, data on mortality rates among patients undergoing MRS in hospitals other than the main referral centers in the northern Brazil are scarce. Objective: To describe the clinical course of patients that submitted to MRS in the major public cardiology referral hospital in the Brazilian Amazon. Methods: Retrospective cohort analysis, by review of medical records of patients who had undergone MRS at Hospital das Clínicas Gaspar Vianna (FHCGV) from January 2013 to June 2014. Results: A total of 179 patients were evaluated. Mortality rate was 11.7% until 30 days after surgery. Waiting time for surgery ≥ 30 days (OR 2.59, 95%CI 1.02 - 6.56, p = 0.039), infection during hospitalization (OR 3.28, 95%CI 1.15 - 9.39, p = 0.021) and need for hemodialysis after surgery (OR 9.06 95%CI 2.07 - 39.54, p = 0.001) were predictors of mortality after CABG. Conclusion: A high mortality rate in the study population was found, higher than that reported in the literature and in other regions of Brazil

ABSTRACT

BACKGROUND@#Necroptosis plays an important role in human atherosclerosis and atheroma development. Since receptor interacting protein kinase-3 (RIP3) acts as a key mediator of necroptosis, this study aimed to explore its relationship between plasma RIP3 levels and coronary artery disease (CAD) and discover a potential new biomarker for screening CAD subtypes and severity.@*METHODS@#A total of 318 patients with CAD who had coronary angiography and 166 controls in Peking Union Medical College Hospital from September 2017 to January 2018 were enrolled in this study. Patients with CAD were divided into three subgroups: patients with stable coronary artery disease (SCAD), patients with unstable angina (UA), and patients with myocardial infarction (MI). The severity of atherosclerosis was determined by Gensini score (GSS). Logistic regression was used to determine the relationship between plasma RIP3 levels and CAD. The correlation between plasma RIP3 and GSS was calculated using multiple linear regression models.@*RESULTS@#Overall, plasma RIP3 levels were significantly higher than serum RIP3 levels. Plasma RIP3 levels in patients with CAD were significantly higher than those in controls. Plasma RIP3 levels were strongly associated with CAD (odds ratio: 6.00, 95% confidence interval 3.04-11.81; P < 0.001). Plasma RIP3 levels increased linearly from controls to patients with SCAD, then patients with UA, and finally to patients with MI. We found a significantly positive correlation between proportion of cases of acute coronary syndrome in subjects and their plasma RIP3 level quartile. Plasma RIP3 levels were also associated with GSS (B 0.027; standard error 0.012; P < 0.05).@*CONCLUSIONS@#Plasma RIP3 levels were independently associated with CAD. Plasma RIP3 levels could potentially supplement clinical assessment to screen CAD and determine CAD severity.

ABSTRACT

OBJECTIVE@#To investigate the expression of connexin 43 (Cx43) in peripheral blood monocytes (PBMCs) from patients with acute coronary syndrome (ACS) and its clinical implications.@*METHODS@#We prospectively collected the clinical data from 40 patients with ACS including 20 with unstable angina pectoris (UAP) and 20 with acute myocardial infarction (AMI) admitted in our department between January, 2018 and June, 2018, with 20 healthy subjects undergoing routine physical examinations serving as the control group. Peripheral blood samples were obtained from all the participants and plasma and PBMCs were separated. Enzyme-linked immunosorbent assay (ELISA) and turbidimetric inhibition immunoassay (TIIA) were used for analysis of plasma levels of interleukin (IL)-1β and high sensitive C-reactive protein (hs-CRP), respectively; real-time quantitative RT-PCR and Western blotting were used to detect the mRNA and protein levels of Cx43 in the PBMCs.@*RESULTS@#Compared with the control group, the patients with UAP showed significantly increased plasma levels of IL-1β and hs-CRP ( < 0.001) and obviously elevated expressions of Cx43 at both mRNA and protein levels in the PBMCs ( < 0.001). Compared with the patients with UAP, the patients with AMI had significantly higher plasma IL-1β and hs-CRP levels ( < 0.001 and < 0.01) but lower expression levels of Cx43 in the PBMCs ( < 0.05).@*CONCLUSIONS@#Patients with UAP and AMI have activated inflammatory responses and reverse changes in Cx43 expression in the PBMCs, suggesting the different roles of Cx43 in the pathogenic mechanisms of different types of ACS.

ABSTRACT

OBJECTIVE: To analyze the cardiovascular outcome of statin medication in individuals retrospectively categorized on the basis of the 2013 American College of Cardiology and American Heart Association (ACC/AHA) guidelines risk assessment and to determine the additional prognostic value of coronary computed tomography angiography (CCTA) in assessing cardiovascular disease (CVD) risk in this group. MATERIALS AND METHODS: This retrospective study reviewed 4255 asymptomatic individuals who had undergone self-referred CCTA with a median follow-up period of 87 months. The primary endpoint was major adverse cardiac events (MACEs); these included cardiac death, nonfatal myocardial infarction, and unstable angina. Individuals recommended for statins according to the ACC/AHA guidelines were analyzed by their assessed risk. RESULTS: MACE occurrence was significantly higher in the statin-recommended (SR) group with significant coronary artery disease (CAD) than in those with insignificant CAD (p < 0.001). In individuals with a normal coronary artery on CCTA, MACEs did not occur regardless of statin medication. In the SR group with significant CAD, there was no significant difference between statin users and non-users (p = 0.810). However, in cases with insignificant CAD, the event-free survival was significantly lower among statin users (p = 0.034). In patients recommended for moderate-intensity statins, the segment involvement score on CCTA was significantly associated with a higher risk of MACEs (hazard ratio 2.558; p = 0.001). CONCLUSION: CCTA might have a potential role in CVD risk stratification among asymptomatic statin candidates.

ABSTRACT

Background: In coronary procedures, although the radial approach protects patients from hemorrhagic complications, it is technically more complex than the femoral approach. Objectives: To test the hypothesis that the radial approach is the procedure of choice in ACS patients due to the high risk of bleeding; and to identify independent predictors of the choice for radial access. Methods: Patients admitted for ACS who underwent invasive coronary procedure were included. We registered the type of access (femoral or radial) chosen by the physician for the first angiography; the investigators did not interfere with this choosing process. Student's t-test was used for comparisons between the CRUSADE and ACUITY scores. Predictors of radial access were compared between the groups. Statistical significance was defined by p < 0,05.Results: Radial access was chosen in 67% of 347 consecutive patients. Patients who underwent radial approach had lower risk of bleeding determined by CRUSADE (30 ± 14 vs. 37 ± 15; p < 0.001) as compared with femoral access. In multivariate analysis, four variables were identified as independent predictors negatively associated with radial access ­ age (OR = 0.98; 95%CI = 0.96 ­ 0.99), creatinine (OR = 0.54; 95%CI = 0.3 ­ 0.98), signs of left ventricular failure (OR = 0.45; 95% CI = 0.22 ­ 0.92) and previous CABG (OR = 0.022; 95%CI = 0.003 ­ 0.166). Conclusion: The propensity to choose radial over femoral access in coronary intervention was not primarily influenced by patients' bleeding risk. Predictors of this decision, identified in the study, indicated less complex patients, suggesting that the difficulty in performing the technique was a stronger determinant than its potential antihemorrhagic effect

ABSTRACT

A dor torácica aguda é um sintoma muito frequente nas unidades de emergência, constituindo-se em um possível sinal de alerta para as doenças com risco iminente de morte. Como a maioria desses pacientes é internada para avaliação de uma possível síndrome coronariana aguda, isso gera um custo hospitalar muito alto por paciente. Por conta dessa possibilidade diagnóstica, muitos emergencistas internam a maioria dos pacientes. Por outro lado, a liberação inapropriada daqueles com infarto agudo do miocárdio representa um risco para o médico e, especialmente, para o paciente. Outro ponto importante é a demora para o atendimento, em que há a influência de fatores relacionados ao paciente, assim como, pontos negativos na logística de atendimento dos serviços de emergência em nosso país. Para excelência no atendimento, é importante uma anamnese detalhada adicionada ao exame físico, a qual permite a elaboração das hipóteses diagnósticas. E para auxiliar os médicos na escolha da hipótese diagnóstica e na tomada rápida de decisão, escores de risco são disponibilizados, os quais, facilmente, identificam a probabilidade de eventos adversos. A conduta imediata de casos com risco de morte imediata tem como principal objetivo reduzir a morbidade e a mortalidade, aumentando, consequentemente, a segurança do profissional da emergência. Sugestões de fluxogramas e algoritmos para o atendimento desses pacientes na sala de emergência definem, de forma objetiva, quem fica e quem pode ser liberado


Acute chest pain is a frequent symptom in emergency units, being a possible war-ning sign of diseases with an imminent risk of death. Since most of these patients are hospitalized to evaluate possible acute coronary syndrome, this generates a very high hospital cost per patient. Because of this diagnostic possibility, emergency professionals admit most patients. In contrast, the inappropriate release of those with acute myocardial infarction poses a risk to the physician and, especially, the patient. Another important point is the delay in care, where there is an influence of patient-related factors, as well as negative points in the logistics of care in the emergency services in our country. For excellence in care, a detailed anamnesis added to the examination is important, allowing the elaboration of diagnostic hypotheses. Moreover, to assist physicians in selecting the diagnostic hypothesis and making fast decisions, there are risk scores that easily identify the likelihood of adverse events. The immediate management of cases with an imminent risk of death is the main objective to reduce morbidity and mortality and, consequently, increase the safety of emergency professionals. Flowcharts and algorithm suggestions targeting patients in the emergency room objectively define who stays and who can be released
