ABSTRACT

Abstract Background Coronary flow and myocardial contractile performance assessed by strain magnitude increase during a dobutamine stress echocardiogram (DSE). Normal coronary flow reserve (CFR) can be attained upon completion of a DSE at age-predicted maximum heart rate (HR) (HRmax = 220 - age)] or submaximal HR [(0.85) HRmax] or before completion (early CFR). Objective To ascertain the association between delta strain and HR in patients with early normal CFR. Methods This prospective study included patients whose normal CFR was obtained before the DSE was completed. Percentage of resting HR (%HRrest) = [(HRrest ÷ HRmax) 100]% and %HR CFR = [(HR at the time of CFR attainment) ÷ (HRmax) 100]% were recorded. Strain was assessed in the left ventricular region of interest, and delta strain was calculated as the difference between the measures obtained at HRrest and after the DSE was completed. Strain agreement analysis for HRrest, %HRrest, and %HR CFR was performed using the kappa coefficient. The Shapiro-Wilk test was used to assess data normality, and the Mann-Whitney test was used to compare the groups. A p-value < 0.05 was considered statistically significant. Results Strain measured -23.3% ± 4.3% at baseline and -31.1% ± 4.9% during the DSE. In delta strain > 8 absolute points, the ROC curves showed an area under the curve of 0.874 ± 0.07 for %HRrest (p = 0.001) and an area under the curve of 0.862 ± 0.07 for %HR CFR (p = 0.001). In delta strain > 8 points, %HRrest ≤ 42.6% of HRmax and %HR CFR ≤ 62.5% of HRmax showed an accuracy of 82.9% and 79.8%, respectively. Conclusion In this study, lower HRrest and HR at the time of CFR attainment had a good association with better myocardial contractile performance, according to the change in strain magnitude.

ABSTRACT

Resumo Fundamento Tem sido demonstrado que um aumento dos níveis séricos de PON1 é protetor contra vários distúrbios. Foi relatado que vários polimorfismos de nucleotídeo único (SNPs, single nucleotide polymorphisms ) do gene PON1 estão associados a níveis e atividade de proteínas enzimáticas séricas. Objetivos Investigar a associação de SNPs do PON1 e atividade da paraoxonase sérica com a doença arterial coronariana (DAC). Métodos Foram estudados 601 pacientes não relacionados submetidos à angiografia coronária, incluindo aqueles com estenose >50% (N=266) e aqueles com estenose <30% (N=335). Os SNPs rs662 e rs840560 do gene da paraoxonase foram determinados utilizando o método ARMS-PCR e o SNP rs705379 foi genotipado utilizando análise de PCR-RFLP. A atividade da paraoxonase sérica foi medida utilizando paraoxon como substrato. O valor de p<0,05 foi considerado significante. Resultados A atividade da paraoxonase sérica não foi significativamente diferente entre os grupos de estudo. Após ajuste para idade, sexo, hipertensão, diabetes mellitus e dislipidemia, o genótipo GG e o modelo codominante de rs662 foram positivamente associados a uma angiografia positiva (respectivamente, OR = 2,424, IC 95% [1,123-5,233], p <0,05, OR = 1,663, IC 95% [1,086-2,547]). A atividade da paraoxonase sérica foi significativamente maior no alelo G e variante GG do polimorfismo rs662, alelo A e variante AA de rs854560 e alelo C e variante CC de rs705379. A análise de haplótipos mostrou que o haplótipo ATC foi significativamente mais prevalente no grupo com angiografia negativa. A análise entre os grupos indicou que o alelo A de rs662 foi significativamente associado à menor atividade da paraoxonase no grupo com angiografia positiva (p=0,019). Conclusões A presença do alelo G do polimorfismo de nucleotídeo único rs662 está independentemente associada ao aumento do risco de DAC.


Abstract Background It has been shown that increased serum PON1 levels are protective against several disorders. Several single nucleotide polymorphisms (SNPs) of the PON1 gene have been reported to be associated with serum enzyme protein levels and activity. Objective To investigate the association of SNPs of PON1 and serum paraoxonase activity with coronary artery disease (CAD). Methods A total of 601 unrelated patients who underwent coronary angiography including those who had >50% stenosis (N=266) and those with <30% stenosis (N=335) were studied. The Paraoxonase gene rs662 and rs840560 SNPs were determined using the ARMS-PCR method and the rs705379 SNP was genotyped using PCR-RFLP analysis. Serum paraoxonase activity was measured using paraoxon as a substrate. A p value of p<0.05 was considered as significant. Results Serum paraoxonase activity was not significantly different between the study groups. After adjustment for age, sex, hypertension, diabetes mellitus and dyslipidemia, the GG genotype and co-dominant model of rs662 was positively associated with a positive angiogram (respectively, OR=2.424, 95%CI [1.123-5.233], p<0.05, OR=1.663, 95%CI [1.086-2.547]). Serum paraoxonase activity was significantly higher in the G allele and GG variant of rs662, A allele and AA variant of rs854560 and C allele and CC variant of rs705379. The haplotype analysis has shown that the ATC haplotype was significantly more prevalent among the angiogram negative group. The analysis between groups indicated that the A allele of rs662 was significantly associated with lower paraoxonase activity in the positive angiogram group (p=0.019). Conclusions The presence of the G allele of the rs662 single nucleotide polymorphism is independently associated to increased risk of CAD.

ABSTRACT

SUMMARY OBJECTIVE: In the current literature, there are few studies investigating the relationship between premature coronary atherosclerosis and nonalcoholic fatty liver disease. We aimed to evaluate the relationship between nonalcoholic fatty liver disease and premature coronary atherosclerosis. METHODS: In this cross-sectional study, female patients aged <55 years and male patients aged <50 years were enrolled. Both male and female patients underwent coronary angiography and abdomen ultrasonography between 2014 and 2019. A stepwise binary logistic regression analysis was carried out to evaluate the independent variables related to premature coronary atherosclerosis and nonalcoholic fatty liver disease. A p-value<0.05 was considered statistically significant. RESULTS: nonalcoholic fatty liver disease was present in 44% of patients (n=377). Notably, 62% of the patients were female and the mean age was 44.5 (39-49) years. In a multivariate analysis, nonalcoholic fatty liver disease was shown to be an independent risk factor of premature coronary atherosclerosis (OR 1.438; 95%CI, 1.050-1.969; p=0.024). CONCLUSIONS: The presence of nonalcoholic fatty liver disease is an important independent risk factor for the development of premature coronary atherosclerosis.

ABSTRACT

Resumo Fundamento O receptor fraco indutor de apoptose semelhante a fator de necrose tumoral solúvel (sTWEAK) é um membro da superfamília de TNF que tem um papel crítico na proliferação e inflamação na circulação arterial. Objetivos Este estudo prospectivo tem o objetivo de mostrar a relação entre os níveis de sTWEAK e calcificação da artéria coronária (CAC) em pacientes com doença renal crônica (DRC). Métodos Este estudo prospectivo incluiu 139 pacientes consecutivos que passaram por angiografia coronariana por tomografia computadorizada, por qualquer motivo, para síndromes coronarianas agudas, de agosto de 2020 a fevereiro de 2021. Um total de 12 pacientes foi excluído do estudo devido aos critérios de exclusão. Os pacientes foram divididos em dois grupos com base em terem um escore CAC menor que 400 (n=84) ou um escore de 400 ou mais (n=43). A significância foi presumida em p-valor bilateral <0,05. Resultados À medida que o escore CAC aumentou, os níveis de sTWEAK diminuíram de forma estatisticamente significativa e detectou-se uma relação forte entre níveis de sTWEAK e escore CAC (r: -0,779, p<0,001). A análise ROC revelou que o nível de corte ideal de sTWEAK para prever o escore CAC de 400 era 761 pg/mL com uma sensibilidade de 71% e especificidade de 73% (AUC: 0,78; IC 95%: 0,70-0,85; p <0,001). Conclusões Embora os estudos em larga escala tenham demonstrado uma correlação positiva entre os níveis de TFGe e sTWEAK, alguns estudos detectaram que o aumento nos níveis de sTWEAK estão associados a mortalidade e gravidade do sistema da artéria coronária em pacientes com DRC. Nossos resultados comprovam nossa hipótese de que os níveis de sTWEAK mostram calcificação coronária em vez de outros tipos de placas ateroscleróticas.


Abstract Background The soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) is a member of the TNF superfamily that plays a critical role in proliferation and inflammation in the arterial circulation. Objectives This prospective study aimed to show the relationship between the sTWEAK levels and coronary artery calcification (CAC) in patients with chronic kidney disease (CKD). Methods This prospective study included 139 consecutive patients undergoing computed coronary angiography for any reason except for acute coronary syndromes from August 2020 to February 2021. A total of 12 patients were excluded from the study due to exclusion criteria. Patients were divided into two groups with regard to having a CAC score of less than 400 (n=84) and 400 or more (n=43). Significance was assumed at a 2-sided p<0.05. Results As the CAC score increased, sTWEAK levels presented a statistically significant decrease, and a strong relationship between sTWEAK levels and the CAC score (r: -0.779, p<0.001) was observed. The ROC analysis revealed that the optimal cut-off level of sTWEAK for predicting the CAC score of 400 was 761 pg/mL with a sensitivity of 71% and a specificity of 73% (AUC: 0.78; 95% CI:0.70-0.85; p < 0.001) Conclusions Even though the large-scale studies showed a positive correlation between eGFR and the sTWEAK levels, some studies found the increased sTWEAK levels to be associated with mortality and the severity of the coronary artery system in patients with CKD. Our results support our hypothesis that the sTWEAK level shows coronary calcification rather than other types of atherosclerotic plaques.

ABSTRACT

Resumo Fundamento O índice imunoinflamatório sistêmico (IIS), derivado das contagens de neutrófilos, plaquetas e linfócitos, representa o equilíbrio homeostático entre os estados inflamatório, imune e trombótico. O IIS é superior a índices como a relação neutrófilos-linfócitos no prognóstico de várias malignidades, além de ser um melhor preditor de futuros eventos cardíacos que os fatores de risco tradicionais após a intervenção coronariana. Objetivos Este estudo objetivou avaliar a relação do IIS com a carga aterosclerótica e complicações hospitalares em pacientes com síndrome coronariana aguda. Métodos Desfechos clínicos, como extensão do dano miocárdico, carga aterosclerótica, sangramento, insuficiência renal aguda, duração da internação e mortalidade hospitalar, foram avaliados em uma coorte retrospectiva de 309 pacientes consecutivos com síndrome coronariana aguda. O IIS foi calculado como (plaqueta x neutrófilos)/contagem de linfócitos na admissão. A população estudada foi categorizada em tercis de IIS. Valores de p<0,05 foram considerados estatisticamente significativos. Resultados Os maiores valores de IIS foram encontrados em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (641,4 com angina pectoris instável, 843,0 com infarto do miocárdio sem supradesnivelamento do segmento ST e 996,0 com infarto do miocárdio com supradesnivelamento do segmento ST; p=0,004). Concentração máxima de troponina (0,94 versus 1,26 versus 3; p<0,001), número de vasos doentes (1 versus 2 versus 2; p<0,001), escore SYNTAX ( The SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery — sinergia entre intervenção coronária percutânea com taxus e cirurgia cardíaca) (9 versus 14 versus 17,5; p<0,001) e duração da internação (2 versus 2 versus 3; p<0,001) também aumentaram de acordo com o tercil de IIS (tercil 1 versus tercil 2 versus tercil 3). O IIS foi um preditor independente de escore SYNTAX (ß: 0,232 [0,001 a 0,003]; p<0,001), extensão do dano miocárdico (ß: 0,152 [0 a 0,001]; p=0,005) e duração da internação (ß: 0,168 [0,0 a 0,001]; p=0,003). Conclusões Este estudo demonstrou que o IIS, um índice hematológico simples, é um marcador melhor de carga aterosclerótica e internação mais longa do que fatores de risco bem conhecidos em pacientes com síndrome coronariana aguda de alto risco.


Abstract Background Systemic immune-inflammatory index (SII), which is derived from neutrophil, platelet and lymphocyte counts, represents the homeostatic balance among inflammatory, immune and thrombotic status. The systemic immune-inflammatory index is superior to indices such as neutrophil-lymphocyte ratio in predicting prognosis in various malignancies, while it is shown to predict future cardiac events better than traditional risk factors after coronary intervention. Objectives Herein, we aimed to evaluate the relationship of the systemic immune-inflammatory index with atherosclerotic burden and in-hospital complications in acute coronary syndrome patients. Methods The clinical outcomes, such as extent of myocardial damage, atherosclerotic burden, bleeding, acute kidney injury, duration of hospital stay and in-hospital mortality, were evaluated in a retrospective cohort of 309 consecutive acute coronary syndrome patients. The systemic immune-inflammatory index was calculated as (Platelet X Neutrophil)/Lymphocyte count on admission. Study population was categorized into tertiles with regard to systemic immune-inflammatory index. A p value of <0.05 was considered statistically significant. Results The highest systemic immune-inflammatory index values were within ST elevation myocardial infarction patients (641.4 in unstable angina pectoris, 843.0 in non-ST elevation myocardial infarction patients and 996.0 in ST elevation myocardial infarction patients; p=0.004). Maximal troponin concentration (0.94 vs. 1.26 vs. 3; p<0.001), number of diseased vessels (1 vs. 2 vs. 2; p<0.001), the SYNTAX (synergy between percutaneous coronary intervention with taxus and coronary artery bypass grafting) score (9 vs. 14 vs. 17.5; p<0.001) and duration of hospital stay (2 vs. 2 vs. 3; p<0.001) also increased with increasing SIItertile(tertile1 vs. tertile 2 vs. tertile 3). Systemic immune-inflammatory index was an independent predictor of SYNTAX score (ß: 0.232 [0.001 to 0.003]; p<0.001), extent of myocardial damage (ß: 0.152 [0 to 0.001]; p=0.005) and duration of hospital stay (ß: 0.168 [0.0 to 0.001]; p=0.003). Conclusions This study has demonstrated that the systemic immune-inflammatory index, a simple hematological index, is a marker of atherosclerotic burden and longer hospital stay on well-known risk factors in high risk acute coronary syndrome patients.

ABSTRACT

RESUMEN Fundamento: la aterosclerosis es una enfermedad del metabolismo general, con daño del endotelio vascular, lo que ha propiciado la realización de múltiples investigaciones utilizando el sistema aterométrico. Objetivo: caracterizar y comparar la lesión aterosclerótica con el uso del Sistema Aterométrico en las arterias coronarias de fallecidos con autopsias médico-legales de acuerdo al grupo de edad. Métodos: se realizó una investigación aplicada, descriptiva, longitudinal y prospectiva. El universo estuvo formado por 183 necropsias consecutivas en el Instituto de Medicina Legal, en el período de 2018 al 2019 y la población de 108 fallecidos divididos por grupos de edades. Las variables operacionalizadas fueron los sectores arteriales principales que irrigan al corazón. Se aplicó el Sistema Aterométrico en las arterias coronaria derecha y coronaria izquierda en su rama descendente anterior y circunfleja. Resultados: se comprobó la estría adiposa en todas las arterias de los menores de 20 años, la placa fibrosa en la coronaria derecha y descendente anterior entre los 21 y 40 años y la placa grave en el grupo entre 41 y 60 años. Las medias aritméticas y desviaciones estándar aumentaron con la edad en todas las variables. Existió correlación de las estrías adiposas entre las tres arterias en el grupo de 21 a 40, en el de 41 a 60 entre la coronaria derecha y la circunfleja y marcada correlación entre la circunfleja y la descendente anterior para las placas fibrosas en el de 41 a 60 años. Conclusiones: la lesión aterosclerótica estuvo presente en las tres arterias, el total de aterosclerosis aumentó con la edad, apareciendo las placas fibrosas a partir de la segunda década de la vida, no se observaron las placas graves antes de los 40 años y el uso del Sistema Aterométrico resultó una herramienta útil para el estudio de la aterosclerosis.


ABSTRACT Background: atherosclerosis is a disease of the general metabolism, with damage to the vascular endothelium, which has led to multiple researches using the atherometric system. Objective: to characterize and compare the atherosclerotic lesion with the use of the atherometric system in the coronary arteries of deceased patients with medico-legal autopsies according to age group. Methods: an applied, descriptive, longitudinal and prospective research was carried out. The universe consisted of 183 autopsies, consecutively from the Institute of Legal Medicine, from 2018 to 2019 and the population of 108 deceased divided by age groups. The operationalized variables were the main arterial sectors that supply the heart. The atherometric system was applied to the right and left coronary arteries in their anterior descending and circumflex branches. Results: fatty streaks were found in all the arteries of those less than 20 years of age, fibrous plaque in the right coronary artery and anterior descending artery in those between 21 and 40 years of age, and severe plaque in the group between 41 and 60 years of age. Arithmetic means and standard deviations increased with age for all variables. There was a correlation of fatty streaks between the three arteries in the group from 21 to 40, in the group from 41 to 60 between the right coronary artery and the circumflex artery, and a marked correlation between the circumflex artery and the anterior descending artery for fibrous plaques in the group from 41 to 60 years old. 60 years. Conclusions: the atherosclerotic lesion was present in the three arteries, the total number of atherosclerosis increased with age, with fibrous plaques appearing from the second decade of life, severe plaques were not observed before the age of 40, and the use of atherometric system turned out to be a useful tool for the study of atherosclerosis.

ABSTRACT

Abstract Objective: We evaluated whether cholesteryl ester transfer protein (CETP) gene polymorphisms are associated with the presence of coronary artery disease (CAD) and/or restenosis in patients with coronary stent. Methods: Two polymorphisms of the CETP gene [−971 A/G (rs4783961), and Taq1B A/G (rs708272)] were genotyped by 5'exonuclease TaqMan assays in 219 patients with CAD (66 patients with restenosis and 153 without restenosis) and 607 control individuals. Results: The distribution of polymorphisms was similar in patients with and without restenosis. However, when the whole group of patients (with and without restenosis) was compared to healthy controls, under dominant model, the G allele of the Taq1B A/G polymorphism was associated with increased risk of CAD (odds ratio [OR] = 1.48, pCDom = 0.032). In the same way, under codominant, dominant, and additive models, the A allele of the −971 A/G polymorphisms was associated with an increased risk of developing CAD (OR = 2.03, pCCo-dom = 0.022, OR = 1.83, pCDom = 0.008, and OR = 1.39, pCAdd = 0.011, respectively). In addition, the linkage disequilibrium showed that the "AG" haplotype was associated with increased risk of developing CAD (OR = 1.28, p = 0.03). Conclusion: This study demonstrates that CETP Taq1B A/G and CETP −971 A/G polymorphisms are associated with an increased risk of developing CAD, but no association with restenosis was observed.


Resumen Objetivo: Evaluamos si los polimorfismos del gen CETP están asociados con la presencia de enfermedad arterial coronaria (EAC) y/o restenosis en pacientes con stent coronario. Métodos: En este estudio se genotiparon dos polimorfismos del gen CETP [−971 A/G (rs4783961) y Taq1B A/G (rs708272)] mediante ensayos de 5'exonucleasa TaqMan en 219 pacientes con EAC (66 pacientes con restenosis y 153 sin restenosis), y 607 individuos de control. Resultados: La distribución de polimorfismos fue similar en pacientes con y sin restenosis. Sin embargo, cuando se comparó todo el grupo de pacientes (con y sin restenosis) con controles sanos, bajo el modelo dominante el alelo G del polimorfismo Taq1B A/G se asocia con un mayor riesgo de EAC (OR = 1.48, pCDom = 0.032). De la misma manera, bajo los modelos co-dominante, dominante y aditivo, el alelo A de los polimorfismos −971 A/G se asocia con un mayor riesgo de desarrollar EAC (OR = 2.03, pCCo-dom = 0.022, OR = 1.83, pCDom = 0,008 y OR = 1.39, pCAdd = 0.011, respectivamente). Adicionalmente, el desequilibrio de ligamiento mostró que el haplotipo "AG" se asocia con un mayor riesgo de desarrollar EAC (OR = 1.28, p = 0.03). Conclusión: En resumen, este estudio demuestra que los polimorfismos CETP Taq1B A/G y CETP −971 A/G están asociados con un mayor riesgo de desarrollar CAD, pero no se observó asociación con restenosis.

ABSTRACT

RESUMEN Introducción: Los ensayos clínicos aleatorizados que compararon la cirugía de revascularización miocárdica (CRM) con la angioplastia transluminal coronaria (ATC) incluyeron todo tipo de técnicas quirúrgicas (con y sin bomba de circulación extracorpórea) y diversos conductos (arteriales y venosos). ¿Es razonable suponer que todas las técnicas quirúrgicas son iguales en términos de mortalidad tardía? Objetivos: Evaluar si la CRM sin circulación extracorpórea y con el empleo de ambas arterias mamarias tiene un beneficio adicional a la revascularización convencional utilizando una sola arteria mamaria en términos de sobrevida a largo plazo para la enfermedad del tronco de la coronaria izquierda (TCI). Material y métodos: Estudio observacional retrospectivo comparativo (n = 723) ajustado por riesgo. Se realizó análisis estratificado según el uso de arteria mamaria interna única (SITA, n = 144) o ambas arterias mamarias internas (BITA, n = 579). Se analizó la sobrevida a los 10 años de la intervención. Resultados: La supervivencia a los 10 años fue significativamente mayor en el grupo en que se utilizaron ambas arterias mamarias (79,0% ± 3,4% vs 67,0% ± 4,9%, log-rank test, p <0,01). Este beneficio también se observó en el análisis ajustado por riesgo (93,0% ± 4,6 vs 69,0% ± 5,7 respectivamente, p = 0,03). El uso de ambas arterias mamarias fue un predictor independiente de sobrevida a 10 años (HR 0,57, IC 95% 0,37-0,87; p = 0,01). Conclusión: El uso de ambas arterias mamarias internas en pacientes con enfermedad del tronco coronario izquierdo sometidos a revascularización coronaria sin circulación extracorpórea se asoció con mayor sobrevida a los 10 años.


ABSTRACT Background: The randomized controlled trials comparing coronary artery bypass graft (CABG) surgery versus percutaneous coronary intervention (PCI) included all types of surgical techniques (on-pump and off-pump) and different conduits (arterial and venous). Is it reasonable to assume that all surgical techniques are equal in terms of late mortality? Objectives: The aim of this study was to evaluate whether off-pump CABG surgery using both mammary arteries provides additional benefit over conventional revascularization using single mammary artery in terms of long-term survival for left main coronary artery (LMCA) disease. Methods: We conducted a retrospective, observational and comparative study (n=723) adjusted for risk. A stratified analysis was performed according to the use of single internal thoracic artery (SITA, n=144) or bilateral internal thoracic arteries (BITA, n=579) analyzing survival at 10 years after the intervention. Results: Survival at 10 years was significantly higher in BITA group (79.0%±3.4% vs 67.0%±4.9%, log-rank test, p <0.01). This advantage was also observed in the risk-adjusted analysis (93.0%±4.6 vs 69.0%±5.7 respectively, p=0.03). The use of BITA was an independent predictor of 10-year survival (HR 0.57, 95% CI 0.37-0.87, p=0.01). Conclusion: The use of bilateral internal mammary arteries in patients with left main coronary artery disease undergoing off-pump coronary artery bypass grafting was associated with higher survival at 10 years.

ABSTRACT

RESUMEN Introducción: La cirugía de revascularización miocárdica (CRM) ha modificado la evolución natural de los pacientes con enfermedad de tronco de la arteria coronaria izquierda (TCI). En nuestro medio es escasa la información relacionada con el seguimiento a mediano y largo plazo de los pacientes intervenidos. Objetivo: Evaluar la implicancia de la enfermedad del TCI en la evolución alejada de los pacientes intervenidos con CRM, y conocer la mortalidad e incidencia de infarto de miocardio (IAM) y/o accidente cerebrovascular (ACV). Resultados: El seguimiento se completó en 438 pacientes (95,6%) con una mediana de 58 meses [Rango intercuartilo (RIC) 35-88 meses]. La sobrevida actuarial fue a 10 años del 91,8% para toda la población, sin diferencias significativas entre el grupo TCI (91,57%) vs. el grupo no TCI (91,86%), HR 1,008, IC95% 0,38-2,65, p=0,98. En el análisis multivariado se encontraron como predictores de mortalidad alejada la fracción de eyección ventricular izquierda preoperatoria (HR 0,95, IC 95% 0,93-0,97, p<0,001), la edad (HR 1,1, IC 95% 1,04-1,13, p< 0,001) y la prioridad no electiva de la cirugía (HR = 3,71; IC 95%: 1,3-10,35; p = 0,01). La sobrevida libre de IAM fue del 96,8% (TCI 94% vs. no TCI 97,4%, p= 0,8) y la libertad de ACV fue del 98% (TCI 97,8% vs. no TCI 98,1%, p= 0,8). Conclusión: En los pacientes sometidos a CRM, la presencia de enfermedad del TCI no incrementó la tasa de eventos duros (muerte, IAM y ACV) en el seguimiento alejado. Los resultados obtenidos en esta serie de pacientes son similares a los publicados en la bibliografía internacional utilizada para desarrollar las guías de revascularización miocárdica.


ABSTRACT Background: Coronary artery bypass grafting (CABG) has modified the natural evolution of patients with left main coronary artery (LMCA) disease. There is little information in our setting regarding the mid- and long-term follow-up of operated patients. Objective: The aim of this study was to evaluate the implication of LMCA disease in the long-term evolution of patients operated on with CABG, and to assess the mortality and incidence of myocardial infarction (AMI) and/or stroke. Results: Follow-up was completed in 438 patients (95.6%) with a median of 58 months [interquartile range (IQR) 35-88 months]. Actuarial survival at 10 years was 91.8% for the entire population, with no significant differences between the LMCA group (91.57%) vs. the non-LMCA group (91.86%), HR 1,008 95% CI 0.38-2.65, p=0.98. In multivariate analysis, preoperative left ventricular ejection fraction (HR = 0.95; 95% CI 0.93-0.97; p < 0.001), age (HR 1.1, 95% CI 1.04-1.13, p<0.001) and non-elective priority of surgery (HR=3.71; 95% CI 1.3-10.35; p=0.01) were independent predictors of long-term mortality. AMI-free survival was 96.8% (LMCA 94% vs. non-LMCA 97.4%, p=0.8) and freedom from stroke was 98% (LMCA 97.8% vs. non-LMCA 98.1 %, p=0.8). Conclusion: In patients undergoing CABG, the presence of LMCA disease did not increase the rate of hard events (death, AMI, and stroke) at the long-term follow-up. The results obtained in this series of patients are similar to those published in the international literature used to develop myocardial revascularization guidelines.

ABSTRACT

Resumo Fundamentos A determinação precisa do colesterol de lipoproteína de baixa densidade (LDL-C) é importante para se alcançar concentrações de LDL-C recomendadas por diretrizes e para reduzir resultados cardiovasculares adversos em pacientes diabéticos. A equação de Friedewald comumente usada (LDL-Cf) produz resultados imprecisos em pacientes diabéticos devido a dislipidemia diabética associada. Recentemente, duas novas equações - Martin/Hopkins (LDL-CMH) e Sampson (LDL-Cs) - foram desenvolvidas para melhorar a precisão da estimativa de LDL-C, mas os dados são insuficientes para sugerir a superioridade de uma equação sobre a outra. Objetivos O presente estudo comparou a precisão e a utilidade clínica das novas equações de Martin/Hopkins e Sampson em pacientes diabéticos. Método Foram incluídos no estudo quatrocentos e dois (402) pacientes com diabetes. O risco cardiovascular dos pacientes e as metas de LDL-C foram calculadas por diretrizes europeias. As concentrações de LDL-Cmh, LDL-Cs, e LDL-Cf calculadas foram comparadas à concentração de LDL-C direto (LDL-Cd) para testar a concordância entre essas equações e LDL-Cd. Um P valor <0,05 foi aceito como estatisticamente significativo. Resultados A LDL-CMH e a LDL-Cs tiveram concordância melhor com o LDL-Cd em comparação com a LDL-Cf, mas não houve diferenças estatísticas entre as novas equações para concordância com o LDL-Cd (Alfa de Cronbach de 0,955 para ambos, p=1). Da mesma forma, a LDL-CMH e a LDL-Cs tinham um grau semelhante de concordância com o LDL-Cd para determinar se o paciente estava dentro da meta de LDL-C (96,3% para LDL-Cmh e 96,0% para LDL-Cs), que eram ligeiramente melhores que a LDL-Cf (94,6%). Em pacientes com uma concentração de triglicérides >400 mg/dl, a concordância com o LDL-Cd foi ruim, independentemente do método usado. Conclusão As equações de Martin/Hopkins e Sampson mostram uma precisão similar para o cálculo de concentrações de LDL-C nos pacientes com diabetes, e ambas as equações são ligeiramente melhores que a equação de Friedewald.


Abstract Background The accurate determination of low-density lipoprotein cholesterol (LDL-C) is important to reach guideline-recommended LDL-C concentrations and to reduce adverse cardiovascular outcomes in diabetic patients. The commonly used Friedewald equation (LDL-Cf), gives inaccurate results in diabetic patients due to accompanying diabetic dyslipidemia. Recently two new equations - Martin/Hopkins (LDL-Cmh) and Sampson (LDL-Cs) - were developed to improve the accuracy of LDL-C estimation, but data are insufficient to suggest the superiority of one equation over the other one. Objective The present study compared the accuracy and clinical usefulness of novel Martin/Hopkins and Sampson equations in diabetic patients. Methods This study included 402 patients with diabetes. Patients' cardiovascular risk and LDL-C targets were calculated per European guidelines. Calculated LDL-Cmh, LDL-Cs, and LDL-Cf concentrations were compared with direct LDL-C concentration (LDL-Cd) to test agreement between these equations and LDL-Cd. A p-value <0.05 was accepted as statistically significant. Results Both LDL-Cmh and LDL-Cs had a better agreement with LDL-Cd as compared to LDL-Cf, but no statistical differences were found among novel equations for agreement with LDL-Cd (Cronbach's alpha 0.955 for both, p=1). Likewise, LDL-Cmh and LDL-Cs showed a similar degree of agreement with LDL-Cd in determining whether a patient was in a guideline-recommended LDL-C target (96.3% for LDL-Cmh and 96.0% for LDL-Cs), which were marginally better than LDL-Cf (94.6%). In patients with a triglyceride concentration >400 mg/dl, agreement with LDL-Cd was poor, regardless of the method used. Conclusion Martin/Hopkins and Sampson's equations show a similar accuracy for calculating LDL-C concentrations in patients with diabetes, and both equations were marginally better than the Friedewald equation.

ABSTRACT

Abstract Introduction: The goal of this study is to investigate the association between diagnosis and severity of coronary artery disease (CAD) and Asprosin level. Methods: Patients diagnosed with CAD who underwent conventional coronary angiography for the first time were included in the present study. The patients were divided into four groups, each consisting of 20 individuals, as medical group, single coronary lesion group, double coronary lesion group, and multiple coronary lesions group. Serum Asprosin values and Gensini scores of the groups were compared in terms of compliance. Results: In this study, Asprosin values were found to be significantly higher in the multiple coronary lesions group than in the medical, single coronary, and double coronary lesion groups (P<0.05). In the double coronary lesion group, Asprosin values were significantly higher (P<0.05) than the in the medical and single coronary lesion groups. It was also found that Asprosin values did not differ at significant levels in the medical and single coronary lesion groups (P>0.05). It was determined that the increases in Asprosin values and Gensini scores were compatible with each other. Conclusion: The present study showed that the increases in serum Asprosin levels, along with the increases in the number of coronary arteries with critical stenosis, might be a marker in diagnosing and determining the severity of CAD.

ABSTRACT

Abstract Objective: To review the evidence behind the role and relevance of redo coronary artery bypass grafting (CABG) in the current practice of percutaneous coronary intervention (PCI). Methods: A comprehensive electronic literature search was performed to identify articles that discuss the practice of PCI and redo CABG in patients that require coronary revascularization. All relevant studies are summarized in narrative manner to reflect current indications and preference. Results: The advancement in utilization of PCI has reduced the rate of redo CABG in patients with previous CABG that requires revascularization of an already treated coronary disease or a new onset of coronary artery stenosis. Redo CABG is associated with satisfactory perioperative outcomes but higher mortality at immediate postoperative period when compared to PCI. Conclusion: Redo CABG patients are less likely to develop comorbidities associated with revascularisation, but the operative mortality is higher and long-term survival rates are similar in comparison to PCI. There is a need for further research into the role of redo CABG in the current advanced practice of PCI.

ABSTRACT

Abstract The prevalence of depression varies from 1 to 17% in different geographic regions, and its incidence is 70% higher in women than men. Today, depression affects more than 300 million people worldwide, affecting twice as many women from adolescence to adulthood. In addition to this earlier onset, depression in women tends to be more severe. Cardiovascular disease and depression are chronic diseases that have a major impact on cardiovascular and all-cause morbidity and mortality, with evidence of a two-way relationship between them, in which depression is a predictor of cardiovascular disease and vice versa. In females, the degree of illness and prognosis are more severe when both diseases are present, than when diagnosed alone. In patients with acute or chronic cardiovascular disease, especially women, a systematic screening for depression should be considered as a preventive strategy of cardiovascular events, aiming to reduce the risk of future events. There are still no clinical studies designed to assess the impact of antidepressant treatment on cardiovascular outcomes in women.
