ABSTRACT

Los síndromes coronarios agudos sin lesiones coronarias han cobrado relevancia en los últimos años, pero aún no se dispone de datos locales. Analizamos un registro de pacientes con infarto agudo de miocardio, en 45 centros del país con residencias de cardiología. Se analizaron 1182 participantes de los cuales 33 (2.8%) no presentaron lesiones coronarias en angiografía, mientras que 89.5% tenían lesiones graves y 7.7% lesiones intermedias. La edad promedio de los pacientes sin lesiones coronarias fue 64.5 ± 13.0 años, 69.7% eran varones, sin diferencias respecto a aquellos con enfermedad epicárdica. La presentación electrocardiográfica más frecuente fue la desviación del segmento ST (13 supradesnivel y 10 infradesnivel del segmento). Además, este subgrupo presentó biomarcadores más bajos (CPK pico 203.5 UI/l, rango [RIC] 102- 422.5 vs. 895.5 UI/l RIC 350-1891, p < 0.0001). La mediana de días de internación fue 4.0 (RIC 3-5.5), siendo menor que la del grupo con enfermedad coronaria intermedia y grave (5.5 días, RIC 4-7, y 6 RIC 4-7, p = 0.003). Al alta, aquellos sin lesiones coronarias recibieron menor prescripción de IECA/ARA II (54.6% vs. 78.0% y 79.7%, p = 0.002) y estatinas (78.8% vs. 87.9% y 91.9%, p = 0.017). Ninguno de este subgrupo falleció durante la inter nación. Nuestros datos sugieren que los infartos sin lesiones coronarias significativas son frecuentes en nuestro medio, aunque probablemente se encuentren subdiagnosticados. Si bien su pronóstico parece más favorable, resulta importante señalar que recibieron menos fármacos para prevenir su recurrencia. Nuevos estudios son necesarios para profundizar el conocimiento de esta enfermedad.


Abstract Acute coronary syndromes without coronary lesions have gained relevance in recent years. However, local data on this condition is scarce. We aimed to explore this entity in a National registry of acute myocardial infarction that was carried out prospectively in hospitals with cardiology residence programs from Ar gentina. We included 1182 patients from 45 centers, where 33 did not present coronary lesions on angiography. The mean age was 64.5 ±13.0 and 69.7% were male, without differences compared to participants with epicardial disease. The most common electrocardiographic presentation was ST segment deviation. In addition, presented lower biomarkers (peak CPK 203.5 IU / l, range [IQR] 102-422.5 vs. 895.5 IU / l IQR 350-1891, p < 0.0001). The median hospitalization was 4.0 days (IQR 3-5.5), lower than the group with intermediate and severe coronary disease (5.5 days, RIC 4-7, and 6, RIC 4-7, p = 0.003). At discharge, less use of ACE/ARB (54.6% vs.78.0% y 79.7%, p = 0.002) and statins (78.8% vs. 87.9% y 91.9%, p = 0.017). No deaths during hospitalization were reported. Our data suggested that infarcts without significant coronary lesions are frequent, although they are probably underdiagnosed. Their prognosis seems to be more favorable, but they receive fewer drugs to prevent recurrence. New studies are necessary to deepen the knowledge of the disease.

ABSTRACT

Resumo Fundamento A ectasia da artéria coronária (EAC) é definida como a dilatação difusa ou localizada do lúmen da artéria coronária com diâmetro de 1,5 a 2,0 vezes o diâmetro da artéria coronária normal adjacente. A relação proteína C-reativa/albumina (CAR, sigla em inglês) é um marcador inflamatório útil que tem sido documentado em doença arterial coronariana. Objetivo Analisar a associação entre a EAC e a CAR. Métodos Um protocolo caso-controle foi utilizado neste estudo. Foram incluídos 102 pacientesconsecutivos com EAC isolada sem estenose (56 homens e 46 mulheres; idade média de 60,4 ± 8,8 anos). O grupo controle era constituido pelo mesmo número de pacientes pareados por sexo e idade com artérias coronárias normais (55 homens e 47 mulheres; idade média de 61,2 ± 9,1 anos). Características clínicas, achados laboratoriais e histórico de uso de medicamentos foram registrados. Foram realizados teste t de Student, teste U de Mann-Whitney, teste do qui-quadrado, análise de regressão linear e logística. Foi considerado estatisticamente significativo p bilateral < 0,05. Resultados A CAR estava aumentada nos pacientes com EAC em comparação com os controles (32 e 16; p < 0,001). Além disso, foi verificado que a CAR era um preditor independente da EAC (razão de chances = 2,202; intervalo de confiança 95%, 1,184 - 5,365; p < 0,001). Conclusão No presente estudo, determinamos que os níveis da CAR estavam significativamente mais altos no grupo EAC que no grupo controle e a CAR estava significativamente correlacionada com a EAC.

Abstract Background Coronary artery ectasia (CAE) is defined as diffuse or localized dilatation of coronary artery lumen with a diameter of 1.5 to 2.0 times the adjacent normal coronary artery. The C-reactive protein to albumin ratio (CAR) is a useful inflammatory marker, which has been documented in coronary artery disease. Objective To analyze the association of CAE and CAR. Methods A case-control protocol was used in this study. We included 102 consecutive patients with isolated CAE without stenosis (56 men and 46 women; mean age 60.4 ± 8.8 years). The control subjects consisted of an equal number of sex and age matched patients with normal coronary arteries (55 men and 47 women; mean age 61.2 ± 9.1 years). Clinical features, laboratory findings, and medication use history were recorded. Student's t test, Mann-Whitney U test, chi-square test, and linear and logistic regression analysis were performed. A 2-sided p < 0.05 was statistically considered significant. Results The CAR was increased in patients with CAE compared to the controls (32 and 16; p < 0.001). In addition, the CAR was found to be an independent predictor of CAE (OR = 2.202; 95% CI 1.184 - 5.365; p < 0.001). Conclusion In the present study, we determined that CAR levels were significantly higher in the CAE group than in the control group, and the CAR was significantly correlated with CAE.

ABSTRACT

Dietary factors may influence the process of atherosclerosis and coronary artery calcification (CAC). This study assessed CAC and its association with dietary intake in asymptomatic men. We evaluated 150 asymptomatic men with mean age of 58.2±5.3 years. The dietary intake was assessed by the Food Consumption Register method. CAC was measured through multidetector computed tomography (MDCT) and assessed in accordance with the Agatston score. Modified Poisson regression model was used to estimate the effects of intake of different nutrients that are prevalent in moderate/severe CAC, adjusted for calorie intake and CAC risk factors by means of prevalence ratios and 95% confidence intervals [95%CI]. An association was found between the intake of some nutrients and moderate/severe CAC. Lower carbohydrate intake (P=0.021) and higher lipid intake (P=0.006) were associated with moderate/severe CAC. After adjustment, the nutrients associated with the prevalence of moderate/severe CAC were carbohydrates (P=0.040), lipids (P=0.005), and saturated fatty acids (SFA) (P=0.013). A 1% increase in lipids and SFA intake caused an increase of 4% [95%CI: 1-7%] and 8% [95%CI: 2-14%] in the prevalence of moderate/severe CAC, respectively. A 1% increase of carbohydrate intake led to a 2% decrease in the likelihood of moderate/severe CAC [95%CI: 1-4%]. These conclusions showed that the higher intake of total lipids and SFA was associated with higher CAC scores, whereas higher carbohydrate intake was associated with lower CAC scores in asymptomatic men.

ABSTRACT

SUMMARY: Thorough knowledge and understanding of coronary arteries and their anatomy is essential when performing cardiac surgery such as a coronary bypass. Coronary angiography is a minimally invasive method used to evaluate the anatomy and obtain different measurements of the coronary arteries. This study was designed to evaluate the endoluminal diameter, trunk length and anatomical distribution of coronary arteries in Chilean subjects without apparent angiographic lesions. Measurements were carried out by 3 trained examiners using Leonardo® software program in 238 Chilean subjects of both sexes with an age-range of 45 to 78 years. Ostium and the distal luminal segments diameters were measured, as well as trunk length of both right and left coronary arteries. Ostium of the anterior interventricular artery, dominance and tortuosity were also registered. In the right coronary artery, the diameters (3.8 ± 1.2 mm and 3.6 ± 1.0 mm) differed according to sex and dominance, and the length (35.2 ± 12.5 mm) differed according to age. In the left coronary artery, the diameters (4.9 ± 1.1 mm and 4.7 ± 1.0 mm) were greater in males than in females. The left coronary artery showed greater diameters and length than the right coronary artery. The prevalence of right arterial dominance was 88.0 %. Patients with right arterial dominance presented greater distal caliber in the right coronary artery than those with left arterial dominance (p<0.05), especially in older patients. Significant arterial tortuosity was observed in seven subjects.


RESUMEN: Un factor clave durante los procedimientos quirúrgicos cardiacos tal como el bypass coronario, es el conocimiento exhaustivo de las arterias coronarias y su anatomía. La angiografía coronaria es un método mínimamente invasivo que se utiliza para evaluar la anatomía y obtener diferentes medidas. El presente estudio fue diseñado para evaluar el diámetro endoluminal, la longitud del tronco y la distribución anatómica de las arterias coronarias en sujetos chilenos sin lesiones angiográficas significativas. Las mediciones fueron realizadas en 238 sujetos chilenos de ambos sexos con un rango etario entre 45 a 78 años. Tres examinadores preparados llevaron a cabo las mediciones utilizando el software Leonardo®. Se midieron los ostios y los diámetros luminales distales de los troncos coronarios derecho e izquierdo, como también las longitudes del tronco de las arterias coronarias derecha e izquierda. Además, se identificaron los ostios de la arteria interventricular anterior, dominancia y tortuosidad. En la arteria coronaria derecha, los diámetros (3,8 ± 1,2 mm y 3,6 ± 1,0 mm) se observaron variaciones según el sexo y la dominancia, y la longitud (35,2 ± 12,5 mm) difirió según la edad. En la arteria coronaria izquierda, los diámetros (4,9 ± 1,1 mm y 4,7 ± 1,0 mm) fueron mayores en los hombres que en las mujeres. La arteria coronaria izquierda mostró mayor diámetro y longitud que la arteria coronaria derecha. La prevalencia de dominancia arterial derecha fue del 88,0 %. Los pacientes con dominancia arterial derecha presentaron mayor calibre distal en la arteria coronaria derecha que aquellos con dominancia arterial izquierda (p <0,05), especialmente en pacientes mayores. En siete sujetos se observó una tortuosidad arterial significativa.

ABSTRACT

Abstract Background: One-catheter strategy, based in multipurpose catheters, allows exploring both coronary arteries with a single catheter. This strategy could simplify coronary catheterization and reduce the volume of contrast administration, by reducing radial spasm. To date, observational studies showed greater benefits regarding contrast consumption and catheterization performance than controlled trials. The aim of this work is to perform the first systematic review and meta-analysis of randomized clinical trials (RCT) to adequately quantify the benefits of one-catheter strategy, with multipurpose catheters, over conventional two-catheter strategy on contrast consumption, and catheterization performance. Methods: A search in PubMed, CINALH, and CENTRAL databases was conducted to identify randomized trials comparing one-catheter and two-catheter strategies. The primary outcome was volume of iodinated contrast administrated. Secondary endpoints, evaluating coronary catheterization performance included: arterial spasm, fluoroscopy time, and procedural time. Results: Five RCT were included for the final analysis, with a total of 1599 patients (802 patients with one-catheter strategy and 797 patients with two-catheter strategy). One-catheter strategy required less administration of radiological contrast (difference in means [DiM] [95% confidence interval (CI)]; −3.831 mL [−6.165 mL to −1.496 mL], p = 0.001) as compared to two-catheter strategy. Furthermore, less radial spasm (odds ratio [95% CI], 0.484 [0.363 to 0.644], p < 0.001) and less procedural time (DiM [95% CI], −72.471 s [−99.694 s to −45.249 s], p < 0.001) were observed in one-catheter strategy. No differences on fluoroscopy time were observed. Conclusions: One-catheter strategy induces a minimal reduction on radiological contrast administration but improves coronary catheterization performance by reducing arterial spasm and procedural time as compared to conventional two-catheter strategy.


Resumen Antecedentes: La estrategia de catéter único permite explorar ambas coronarias con un solo catéter. Nuestro objetivo es realizar la primera revisión sistemática y meta-análisis de ensayos clínicos aleatorizados para cuantificar adecuadamente los beneficios de la estrategia de catéter único, con catéteres multipropósito, sobre la estrategia convencional de dos catéteres. Métodos: Se realizó una búsqueda en PubMed, CINALH y CENTRAL, identificando ensayos aleatorizados que compararan estrategias de un catéter y dos catéteres. El resultado primario fue volumen de contraste administrado. Los secundarios, que evaluaron el rendimiento del cateterismo, incluyeron: espasmo radial, tiempo de fluoroscopia y de procedimiento. Resultados: Se incluyeron cinco ensayos, totalizando 1,599 pacientes (802 con estrategia de un catéter y 797 con estrategia de dos catéteres). La estrategia de catéter único requirió menos contraste (diferencia-de-medias; −3.831 mL [−6.165 mL a −1.496 mL], p = 0.001), presentando menos espasmo radial (odds ratio, 0.484 [0.363 a 0.644], p < 0.001) y menos tiempo de procedimiento (diferencia-de-medias; −72.471 s [−99.694 s a −45.249 s], p < 0.001). No hubo diferencias en el tiempo de fluoroscopia. Conclusiones: La estrategia de catéter único induce una reducción mínima en la administración de contraste, pero mejora el rendimiento del cateterismo al reducir el espasmo radial y el tiempo de procedimiento en comparación con la estrategia convencional.

ABSTRACT

Resumo Fundamento A doença arterial coronariana (DAC) associada à quimioterapia está se tornando um tema emergente na prática clínica. Contudo, o mecanismo subjacente da quimioterapia associada à DAC permanence incerto. Objetivos O estudo investigou a associação entre a quimioterapia e as anomalias anatômicas ateroscleróticas das artérias coronárias dentre pacientes com cancer de pulmão. Métodos Foram incluídos pacientes submetidos à angiografia coronária (AGC), entre 2010 e 2017, com câncer de pulmão prévio. Os fatores de risco associados à DAC e os dados sobre o câncer de pulmão foram avaliados. Avaliamos as anomalias das artérias coronárias de acordo com o escore SYNTAX (SXescore) calculado à AGC. Na análise de regressão logística, o escore SYNTAX foi classificado como alto (SXescoreALTO) se ≥22. Os dados foram analisados através de estatística descritiva e análise de regressão. Resultados Ao todo, 94 pacientes foram incluídos no estudo. O SXescore foi mais alto no grupo com quimioterapia quando comparado com o grupo sem quimioterapia (25,25, IIQ [4,50-30,00] versus 16,50, IIQ [5,00-22,00]; p = 0,0195). A taxa do SXescoreALTO foi maior no grupo com quimioterapia do que no no grupo sem quimioterapia (58,33% versus 25,86; p = 0,0016). Tanto a análise de regressão logística univariada (OR: 4,013; 95% IC:1,655-9,731) quanto a multivariada (OR: 5,868; 95% IC:1,778-19,367) revelaram que a quimioterapia aumentou o risco de uma maior taxa do SXescoreALTO. A análise multivariada de regressão logística Stepwise mostrou que o risco para DAC anatômica mais grave aumenta com a quimioterapia como um todo em 5.323 vezes (95% IC: 2,002-14,152), e com o regime à base de platina em 5,850 vezes (95% IC: 2,027-16,879). Conclusões A quimioterapia está associada com a complexidade e gravidade anatômica da DAC, o que pode explicar, em parte, o maior risco de DAC associada à quimioterapia dentre pacientes com câncer de pulmão.

Abstract Background Chemotherapy-related coronary artery disease (CAD) is becoming an emerging issue in clinic. However, the underlying mechanism of chemotherapy-related CAD remains unclear. Objective The study investigated the association between chemotherapy and atherosclerotic anatomical abnormalities of coronary arteries among lung cancer patients. Methods Patients undergoing coronary angiography (CAG) between 2010 and 2017, who previously had lung cancer, were examined. Risk factors associated with CAD and information about lung cancer were evaluated. We assessed coronary-artery abnormalities by SYNTAX score (SXscore) based on CAG. In logistic-regression analysis, we defined high SXscore (SXhigh) grade as positive if ≥22. Data were analyzed through descriptive statistics and regression analysis. Results A total of 94 patients were included in the study. The SXscore was higher in the chemotherapy group than in the non-chemotherapy group (25.25, IQR [4.50-30.00] vs. 16.50, IQR [ 5.00-22.00], p = 0.0195). The SXhigh rate was greater in the chemotherapy group than in the non-chemotherapy group (58.33% vs. 25.86; p = 0.0016). Both univariate (OR:4.013; 95% CI:1.655-9.731) and multivariate (OR:5.868; 95% CI:1.778-19.367) logistic-regression analysis revealed that chemotherapy increased the risk of greater SXhigh rates. Multivariate stepwise logistic-regression analysis showed the risk of more severe anatomical CAD is increased by chemotherapy as a whole by 5.323 times (95% CI: 2.002-14.152), and by platinum-based regimens by 5.850 times (95% CI: 2.027-16.879). Conclusions Chemotherapy is associated with anatomical complexity and severity of CAD, which might partly account for the higher risk of chemotherapy-related CAD among lung cancer patients.

ABSTRACT

Una de cada 4 coronariografías realizadas por isquemia miocárdica presenta lesiones menores al 50% Este dato desencadenó un creciente interés en la comunidad médica. La Sociedad Americana de Cardiología publicó recientemente un artículo que describe la posición consensuada de un grupo de expertos sobre la fisiopatología, el diagnóstico y el tratamiento de esta entidad. Nuestro trabajo refleja una revisión narrativa y la posición de un grupo de expertos pertenecientes a diferentes instituciones con servicios de Cardiología jerarquizados. Aborda aspectos fisiopatológicos y diagnósticos para comprender el enfoque actual del tratamiento, tanto en pacientes que ingresan con diagnóstico de MINOCA (infa rto de miocardio con lesiones angiográficas no graves) o de INOCA (angina e isquemia demostradas, pero sin lesiones coronarias que justifiquen este síndrome).


One in every four coronarographies performed to study myocardial ischemia shows coronary angiographic stenosis less than 50%. This data triggered an increasing interest in the medical community. The American Society of Cardiology recently published a position paper about the pathophysiology, diagnosis and treatment of this entity. Our group performed a narrative review reflecting the opinion of cardiology experts from different centers in Argentina. It aims physiopatologic and diagnostic aspect to understand the current approach in patients with MINOCA (myocardial infarction with non-obstructive coronary arteries) e INOCA (demonstrated angina and ischemia but without coronary lesions that justify this syndrome).

ABSTRACT

INTRODUCTION: Coronary artery disease is the largest cause of mortality in the world. The main risk factors for its development include systemic arterial hypertension and type 2 diabetes mellitus. OBJECTIVE: To search for predictors of the development of plaques and obstructions in coronary arteries and to determine whether the exercise test is a reliable pretest for coronary angiotomography. METHODS: 883 computed tomography reports of coronaries were analyzed. Sociodemographic information, health conditions and results of the exercise test from patients were collected, along with calcium score, percentile and number of arterial segments with significant obstruction. The data were analyzed using descriptive and inferential statistics. Significance was considered for p<0.05. RESULTS: It observed that the statistically significant predictors to the calcium score were male, being over 60 years old, having type 2 diabetes mellitus and systemic arterial hypertension. There was no relationship with high BMI and coronary obstruction. Regarding the exercise test, it was possible to observe that the majority of individuals who were positive in the exercise test, did not have a positive calcium score or significant coronary obstructions. CONCLUSION: The predictors for the development of coronary plaques and obstructions were male, aged ≥60 years, having type 2 diabetes mellitus and systemic arterial hypertension.


INTRODUÇÃO: A doença arterial coronariana representa a maior causa de mortalidade no mundo, sendo que os principais fatores de risco para o seu desenvolvimento incluem a hipertensão arterial sistêmica e a diabetes mellitus tipo 2. OBJETIVO: Detectar os preditores para o desenvolvimento de placas e obstruções coronarianas detectadas através da tomografia computadorizada de artérias coronárias além de determinar se o teste de esforço é um pré-teste fidedigno para a realização angiotomografia coronariana. MÉTODOS: Foi realizada análise de 883 laudos de exames de TC de coronárias e coletados dados sociodemográficos, de saúde e o resultado do teste de esforço, juntamente com escore de cálcio, percentil e quantidade de segmentos arteriais com obstruções significativas. Os dados foram analisados pela estatística descritiva e inferencial (p<0,05). RESULTADOS: Foi possível observar que os preditores com valores estatisticamente significantes em relação ao escore de cálcio foi ser do sexo masculino, possuir idade acima de 60 anos, portar diabetes mellitus tipo 2 e hipertensão arterial sistêmica, não houve relação entre IMC elevado, que sugere sobrepeso, e obstrução coronariana. Em relação ao teste de esforço foi possível observar que a maioria dos indivíduos que apresentaram positividade no teste de esforço, não apresentavam escore de cálcio positivo ou obstruções coronarianas significativas. CONCLUSÃO: Os preditores para o desenvolvimento de placas e obstruções coronarianas foi pertencer ao sexo masculino, apresentar idade ≥60 anos, ser portadores de diabetes mellitus tipo 2 e hipertensão arterial sistêmica.

ABSTRACT

Abstract Background: Coronary dilatation is the most important complication of Kawasaki disease (KD) and, in addition to some clinical characteristics, is common to KD and febrile exanthematous illnesses (FEIs). Objective: To assess whether children with FEI, who do not meet the criteria for KD, have changes in coronary arteries dimensions. Methods: Echocardiography was performed within the first two weeks of the disease in patients < 10 years with fever and exanthema without other KD criteria. To make a comparison with KD patients, we reviewed the echocardiograms and medical records of patients with a diagnosis of KD of the last five years. Coronary ectasia was assessed using Z scores of coronary arteries. The means of the dimensions of the coronary arteries were compared with a z test and a level of significance of 0.05 was adopted. Results: A total of 34 patients were included, 22 (64.7%) with FEI, and 12(35.2%) with a diagnosis of KD. Using the Z scores of coronary artery, a dilation of any of the coronary artery branches was observed in six (27.2%) patients with FEI. Conclusions: An important percentage of patients with FEI has coronary artery dilation.


Resumo Fundamento: A dilatação das artérias coronárias é a principal complicação da Doença de Kawasaki (DK) e, além de algumas características clínicas, é comum à DK e a doenças exantemáticas febris (DEFs). Objetivo: Avaliar se crianças com DEF e que não têm critério para DK apresentam alterações nas dimensões das artérias coronárias. Métodos: Foi realizada ecocardiografia nas primeiras duas semanas da doença em crianças com idade inferior a 10 anos, que apresentaram febre e exantema e nenhum outro critério de DK. Para comparar com pacientes com DK, fizemos a revisão de ecocardiogramas e prontuários médicos de pacientes com diagnóstico de DK dos últimos cinco anos. Ectasia coronária foi avaliada usando escore Z das artérias coronárias. As médias das dimensões das artérias coronárias foram comparadas pelo teste z, e um nível de significância de 0,05 foi adotado. Resultados: Foram incluídos no estudo 34 pacientes, 22 (64,7%) com diagnóstico de DEF e 12 (35,2%) com diagnóstico de DK. Usando o escore Z das artérias coronárias, observou-se dilatação em algum dos ramos da artéria coronária em seis (27,2%) pacientes com DEF. Conclusão: Uma porcentagem importante dos pacientes com DEFs apresenta dilatação das artérias coronárias.

ABSTRACT

Abstract Objective: To evaluate the patency of individual and sequential coronary artery bypass in patients with ischemic heart disease. Methods: We searched PubMed, Cochrane Library, Excerpta Medica Database, and ClinicalTrials.gov databases for controlled trials. Endpoints included graft patency, anastomosis patency, occluded rates in left anterior descending (LAD) system and right coronary artery (RCA) system, in-hospital mortality, and follow-up mortality. Pooled risk ratios (RRs) and standardized mean difference (SMD) were used to assess the relative data. Results: Nine cohorts, including 7100 patients and 1440 grafts under individual or sequential coronary artery bypass. There were no significant differences between individual and sequential coronary artery bypass in the graft patency (RR=0.96; 95% CI=0.91-1.02; P=0.16; I2=87%), anastomosis patency (RR=0.95; 95% CI=0.91-1.00; P=0.05; I2=70%), occluded rate in LAD system (RR=1.03; 95% CI=0.92-1.16; P=0.58; I2=37%), occluded rate in RCA system (RR=1.36; 95% CI=0.72-2.57; P=0.35; I2=95%), in-hospital mortality (RR=1.57; 95% CI=0.92-2.69; P=0.10; I2=0%), and follow-up mortality (RR=0.96; 95% CI=0.36-2.53; P=0.93; I2=0%). Conclusion: No significant differences on clinical data were observed regarding anastomosis patency, occluded rate in LAD system, occluded rate in RCA system, in-hospital mortality, and follow-up mortality, indicating that the patency of individual and the patency of sequential coronary artery bypass are similar to each other.
