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.

BACKGROUND@#Limited data are available on the comparison of clinical outcomes of complete vs. incomplete percutaneous coronary intervention (PCI) for patients with chronic total occlusion (CTO) and multi-vessel disease (MVD). The study aimed to compare their clinical outcomes.@*METHODS@#A total of 558 patients with CTO and MVD were divided into the optimal medical treatment (OMT) group ( n = 86), incomplete PCI group ( n = 327), and complete PCI group ( n = 145). Propensity score matching (PSM) was performed between the complete and incomplete PCI groups as sensitivity analysis. The primary outcome was defined as the occurrence of major adverse cardiovascular events (MACEs), and unstable angina was defined as the secondary outcome.@*RESULTS@#At a median follow-up of 21 months, there were statistical differences among the OMT, incomplete PCI, and complete PCI groups in the rates of MACEs (43.0% [37/86] vs. 30.6% [100/327] vs. 20.0% [29/145], respectively, P = 0.016) and unstable angina (24.4% [21/86] vs. 19.3% [63/327] vs. 10.3% [15/145], respectively, P = 0.010). Complete PCI was associated with lower MACE compared with OMT (adjusted hazard ratio [HR] = 2.00; 95% confidence interval [CI] = 1.23-3.27; P = 0.005) or incomplete PCI (adjusted HR = 1.58; 95% CI = 1.04-2.39; P = 0.031). Sensitivity analysis of PSM showed similar results to the above on the rates of MACEs between complete PCI and incomplete PCI groups (20.5% [25/122] vs. 32.6% [62/190], respectively; adjusted HR = 0.55; 95% CI = 0.32-0.96; P = 0.035) and unstable angina (10.7% [13/122] vs. 20.5% [39/190], respectively; adjusted HR = 0.48; 95% CI = 0.24-0.99; P = 0.046).@*CONCLUSIONS@#For treatment of CTO and MVD, complete PCI reduced the long-term risk of MACEs and unstable angina, as compared with incomplete PCI and OMT. Complete PCI in both CTO and non-CTO lesions can potentially improve the prognosis of patients with CTO and MVD.

Em pacientes que apresentam síndromes coronárias agudas e são tratados com intervenção coronária percutânea, a prescrição do esquema antiplaquetário duplo, composto de ácido acetilsalicílico e um inibidor dos receptores P2Y12, é mandatória, contribuindo para a redução de eventos cardíacos maiores. No entanto, ao mesmo tempo em que previne eventos isquêmicos, essa associação pode precipitar complicações hemorrágicas maiores, o que é mais comumente observado quando são prescritos os medicamentos mais potentes, como o prasugrel ou o ticagrelor. Essas constatações levaram à procura de alternativas terapêuticas capazes de manter a proteção contra eventos isquêmicos e, ao mesmo tempo, prevenir a ocorrência de hemorragias. Uma das estratégias que está em estudo é a de-escalação dos inibidores P2Y12, que consiste no uso dos medicamentos mais potentes numa fase precoce após o procedimento, com substituição deles pelo clopidogrel, após um período de, em geral, 30 dias de evolução; outra possibilidade seria a simples redução da dose do fármaco de maior potência, algo que, até o momento, só pode ser cogitado com o prasugrel. A de-escalação pode ser feita de forma guiada, utilizando testes de mensuração objetiva da agregação plaquetária ou exames para avaliar o perfil genético dos pacientes, ou não guiada, na qual o cardiologista simplesmente faz a substituição ou redução da dose ao fim do período estipulado, sem o auxílio de exames complementares. A literatura contempla ensaios clínicos com essas duas opções de estratégia, os quais são discutidos nesta revisão. Até o momento, nenhuma diretriz médica recomenda de forma explícita o uso regular dessa alternativa terapêutica.

In patients who have acute coronary syndromes and are treated with percutaneous coronary intervention, the prescription of a dual antiplatelet regimen, consisting of acetylsalicylic acid and a P2Y12 receptor inhibitor, is mandatory, contributing to the reduction of major cardiac events. However, while preventing ischemic events, this association may precipitate major bleeding complications, which is more commonly seen when more potent drugs, such as prasugrel or ticagrelor, are prescribed. These findings led to the search for therapeutic alternatives that could maintain the protection against ischemic events and, at the same time, prevent the occurrence of hemorrhages. One of the strategies being studied is de-escalation of P2Y12 inhibitors, which consists of the use of more potent drugs in an early phase after the procedure, replacing them with clopidogrel, after a period of, in general, 30 days of clinical course. Another possibility would be to simply reduce the dose of the most potent drug, which so far can only be considered with prasugrel. De-escalation can be done in a guided way, using objective measuring tests of platelet aggregation or exams to assess the genetic profile of patients, or unguided, in which the cardiologist simply replaces or reduces the dose at the end of the stipulated period, with no ancillary tests. The literature includes clinical trials with these two strategy options, which are discussed in this review. So far, no medical guideline explicitly recommends the regular use of this therapeutic alternative.

BACKGROUND@#High on-clopidogrel platelet reactivity could be partially explained by loss-of-function alleles of CYP2C19, the enzyme that converts clopidogrel into its active form. Shexiang Tongxin Dropping Pill (STDP) is a traditional Chinese medicine to treat angina pectoris. STDP has been shown to improve blood flow in patients with slow coronary flow and attenuate atherosclerosis in apolipoprotein E-deficient mice. However, whether STDP can affect platelet function remains unknown.@*OBJECTIVE@#The purpose of this study is to examine the potential effects of STDP on platelet function in patients undergoing percutaneous coronary intervention (PCI) for unstable angina. The interaction between the effects of STDP with polymorphisms of CYP2C19 was also investigated.@*DESIGN, PARTICIPANTS AND INTERVENTION@#This was a single-center, randomized controlled trial in patients undergoing elective PCI for unstable angina. Eligible subjects were randomized to receive STDP (210 mg per day) plus dual antiplatelet therapy (DAPT) with clopidogrel and aspirin or DAPT alone.@*MAIN OUTCOME MEASURES@#The primary outcome was platelet function, reflected by adenosine diphosphate (ADP)-induced platelet aggregation and platelet microparticles (PMPs). The secondary outcomes were major adverse cardiovascular events (MACEs) including recurrent ischemia or myocardial infarction, repeat PCI and cardiac death; blood biomarkers for myocardial injury including creatine kinase-MB isoenzyme (CK-MB) and high-sensitive troponin I (hsTnI); and biomarkers for inflammation including intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), monocyte chemoattractant protein-1 (MCP-1) and galectin-3.@*RESULTS@#A total of 118 subjects (mean age: [66.8 ± 8.9] years; male: 59.8%) were included into analysis: 58 in the control group and 60 in the STDP group. CYP2C19 genotype distribution was comparable between the 2 groups. In comparison to the control group, the STDP group had significantly lower CK-MB (P < 0.05) but similar hsTnI (P > 0.05) at 24 h after PCI, lower ICAM-1, VCAM-1, MCP-1 and galectin-3 at 3 months (all P < 0.05) but not at 7 days after PCI (P > 0.05). At 3 months, the STDP group had lower PMP number ([42.9 ± 37.3] vs. [67.8 ± 53.1] counts/μL in the control group, P = 0.05). Subgroup analysis showed that STDP increased percentage inhibition of ADP-induced platelet aggregation only in slow metabolizers (66.0% ± 20.8% in STDP group vs. 36.0% ± 28.1% in the control group, P < 0.05), but not in intermediate or fast metabolizers. The rate of MACEs during the 3-month follow-up did not differ between the two groups.@*CONCLUSION@#STDP produced antiplatelet, anti-inflammatory and cardioprotective effects. Subgroup analysis indicated that STDP inhibited residual platelet reactivity in slow metabolizers only.@*TRIAL REGISTRATION@#This study was registered on ChiCTR-IPR-16009785.

Objective We used standardized patients to evaluate the accuracy and explore the influencing factors of the diagnosis of unstable angina pectoris and type 2 diabetes by primary healthcare providers in Sichuan rural areas,aiming to provide a scientific basis for improving the diagnosis accuracy of primary healthcare providers for the two chronic diseases. Methods A multi-stage stratified random cluster sampling method was adopted to select 100 villages from 50 townships in 5 districts/counties in Zigong city,Sichuan province. General and internal medicine practioners who were on duty on the survey day were enrolled in the survey.Two rounds of data collection were conducted.In the first round,the basic information of providers from township health centers and village clinics was collected.One month after the the first survey,standardized patients were used to collect the information related to the diagnosis of unstable angina pectoris and type 2 diabetes by rural primary providers.Logistic regression was carried out to analyze the factors influencing the diagnosis accuracy. Results A total of 172 rural primary healthcare providers were enrolled in the survey,who completed 186 standardized patient visits and showed the correct diagnosis rate of 48.39%.Specifically,the correct diagnosis rates of unstable angina pectoris and type 2 diabetes were 18.68%(17/91) and 76.84%(73/95),respectively.The providers with medical practitioner qualifications were more likely to make correct diagnosis(OR=4.857,95%CI=1.076-21.933, P=0.040).The providers who involved more necessary consultation and examination items in the diagnosis process had higher probability of correct diagnosis(OR=1.627,95%CI=1.065-2.485, P=0.024).Additionally,the providers were more likely to make a correct diagnosis for type 2 diabetes than for unstable angina pectoris(OR=6.306,95%CI=3.611-11.013, P<0.001). Conclusions The overall diagnosis accuracy of unstable angina pectoris and type 2 diabetes was relatively low among primary healthcare providers in Sichuan rural areas.The training of diagnosis process can be taken as a key for improving providers' practice ability so as to increase the diagnosis accuracy of chronic diseases.

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.

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.

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.

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..

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.

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.

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.

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.

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
