RESUMO

BACKGROUND: Abdominal aortic aneurysm (AAA) is a pathological enlargement of infrarenal aorta close to the aortic bifurcation, and it is an important cause of mortality in the elderly. Therefore, the biomarker identification for early diagnosis is of great interest for clinical benefit. It is known that microRNAs (miRNAs) have important roles via target genes regulation in many diseases. This study aimed to identify miRNAs and their target genes involved in the pathogenesis of AAA. METHODS: Tissue samples were obtained from patients who underwent AAA surgery and from organ donors (control group). Quantitative PCR Array was applied to assess 84 genes and 384 miRNAs aiming to identify differentially expressed targets (AAA n = 6, control n = 6), followed by validation in a new cohort (AAA n = 18, control n = 6) by regular qPCR. The functional interaction between validated miRNAs and target genes was performed by the Ingenuity Pathway Analysis (IPA) software. RESULTS The screening cohort assessed by PCR array identified 10 genes and 59 miRNAs differentially expressed...(AU)

RESUMO

BACKGROUND: Abdominal aortic aneurysm (AAA) is a pathological enlargement of infrarenal aorta close to the aortic bifurcation, and it is an important cause of mortality in the elderly. Therefore, the biomarker identification for early diagnosis is of great interest for clinical benefit. It is known that microRNAs (miRNAs) have important roles via target genes regulation in many diseases. This study aimed to identify miRNAs and their target genes involved in the pathogenesis of AAA. METHODS: Tissue samples were obtained from patients who underwent AAA surgery and from organ donors (control group). Quantitative PCR Array was applied to assess 84 genes and 384 miRNAs aiming to identify differentially expressed targets (AAA n = 6, control n = 6), followed by validation in a new cohort (AAA n = 18, control n = 6) by regular qPCR. The functional interaction between validated miRNAs and target genes was performed by the Ingenuity Pathway Analysis (IPA) software. RESULTS: The screening cohort assessed by PCR array identified 10 genes and 59 miRNAs differentially expressed (≥2-fold change, p<0.05). Among these, IPA identified 5 genes and 9 miRNAs with paired interaction. ALOX5, PTGIS, CX3CL1 genes, and miR-193a-3p, 125b-5p, 150-5p maintained a statistical significance in the validation cohort. IPA analysis based on the validated genes and miRNAs revealed that eicosanoid and metalloproteinase/TIMP synthesis are potentially involved in AAA. CONCLUSION: Paired interactions of differentially expressed ALOX5, PTGIS, CX3CL1 genes, and miR-193b-3p, 125b-5p, 150-5p revealed a potentially significant role of the eicosanoid synthesis and metalloproteinase/TIMP pathways in the AAA pathogenesis.

RESUMO

BACKGROUND: The objectives of this study are to validate the Quality of Life in Cardiovascular Surgery (QLCS) questionnaire and to observe the evolution of quality of life in the first year of postoperative follow-up of patients who underwent coronary artery bypass grafting (CABG). METHODS: This was a prospective observational study of patients undergoing CABG from July 2016 to June 2017 who was evaluated for internal consistency by Cronbach's alpha, test-retest reproducibility by correlation coefficient of concordance, and accuracy for interrater reliability by the kappa statistic. The nonparametric analysis of variance test was used for analysis of repeated measures, during follow-up, of the QLCS was considered significant at p < 0.05. RESULTS: Included were 360 patients, with a mean age of 63 years; 72% were men. Cronbach's alpha was 0.82, demonstrating adequate internal consistency. The correlation coefficient of concordance was 0.93 and accuracy 0.99, showing good precision and accuracy. The kappa statistic for questions ranged from 0.58 to 0.78, which ensures a moderate reproducibility. Scores of the QLCS in patients undergoing CABG of 17.69, 18.82, and 19.52 were found at 1, 6, and 12 months, respectively. Thus there was a progressive improvement in quality of life over the first year of follow-up (p < 0.0001). CONCLUSIONS: The QLCS proved to be a good questionnaire in this population, with adequate internal consistency and moderate reproducibility. Its use revealed a progressive and significant improvement in the quality of life of patients undergoing CABG. (AU)

RESUMO

BACKGROUND: Coronary Artery Bypass Grafting (CABG) reduces mortality in Heart Failure (HF) and coronary artery disease (CAD) patients (pts). There is a paucity of data on the utilization of optimal medical therapy (OMT) in HF and CAD pts after revascularization and the impact on long term outcomes. We evaluate the impact of baseline use of OMT versus Non-OMT on long-term clinical outcomes in pts receiving CABG compared to patients with medical treatment alone (MED). METHODS: The STICH trial randomized 1212 pts with CAD and left ventricular ejection fraction (LVEF) ≤ 35% to CABG + MED versus MED alone. OMT was defined as a combination of 4 drugs: ACEI/ARB, BB, statin, and at least one antiplatelet drug at baseline, with a median follow up over 9.8 years. RESULTS: At baseline, 58.7% of the pts were on OMT (CABG 56.1%; MED 61.5%), remaining stable or increasing similarly for both groups during follow up, for example, at 1 year, CABG 73.2% and Med 74.3%. Age, gender, diabetes were similar. OMT pts had less atrial fibrillation, lower angina score class, less advance heart failure class and better renal function. There were no differences in LVEF and end systolic and diastolic volume index. OMT use at baseline was associated with a significantly lower all-cause mortality compared to Non- OMT pts (58.8% vs 67.6%, log-rank P<0.001), lower cardiovascular mortality (40.3% vs 51.4%, log-rank P<0.001) and lower HF death, 11.2% vs 15.6%, log-rank P<0.001). Sudden death was not different (21.5% vs 23.4%, P=0.058). In a multivariable Cox model, OMT was associated with a lower All-cause mortality (HR 0.78, 95%CI 0.66-0.91 P=0.001). The effect of OMT was similar for both CABG and MED only pts for these outcomes (p=0.189 for interaction). Hospitalization for HF was not reduced with OMT. CONCLUSION: OMT is associated with lower all-cause mortality in CABG eligible HF pts, regardless of the lower baseline risk among OMT pts and the performance of CABG. OMT should be strongly considered for all pts with ischemic cardiomyopathy regardless of whether CABG is performed. (AU)

RESUMO

OBJECTIVE: Elaboration and internal validation of the Quality of Life in Cardiovascular Surgery (QLCS) questionnaire adapted to the reality of Brazilian cardiovascular surgery. METHODS: Cross-sectional pilot study of a prospective cohort included in the Documentation and Surgical Registry Center (CEDREC) for internal validation of the QLCS questionnaire. Four hundred forty-five patients submitted to cardiovascular surgery and who answered a QLCS questionnaire 30 days after hospital discharge were included. It was applied via telephone. To verify the questions' internal consistency, Cronbach's alpha was used. The total QLCS score was calculated as the sum of 5 questions, ranging from 5 to 25 points. Mann-U-Whitney test was used to relate the symptoms with the quality of life (QoL). Level of significance was 5%. RESULTS: After 30 days of surgery, about 95% of the patients had already returned to normal routine and 19% of them were already performing physical activity. In the evaluation of the QLCS's internal consistency, a Cronbach's alpha of 0.74 was found, suggesting that this was probably an adequate questionnaire to evaluate QoL in this population. In the comparison between the presence and absence of symptoms and the median of QoL, the presence of pain at the incision (P=0.002), chest pain (P<0.001), shortness of breath (P<0.001), and return to physical activity (P<0.001) were statistically significant. CONCLUSION: The process of elaboration and validation of questionnaires includes a series of steps. The QLCS questionnaire is probably an adequate tool for the evaluation of QoL in the postoperative patient of cardiovascular surgery, in this first stage of internal validation.

RESUMO

BACKGROUND: Studies have pointed out a higher mortality after coronary artery bypass surgery (CABG) in patients with stent. OBJECTIVE: To evaluate inflammatory markers in peripheral blood cells and in coronary artery tissue samples obtained during CABG in patients with stent compared to controls. METHODS: The case series consisted of two groups, one with previous stent implantation (n = 41) and one control (n = 26). The expression of the LIGHT, IL-6, ICAM, VCAM, CD40, NFKB, TNF, IFNG genes was analyzed in peripheral blood cells collected preoperatively. The coronary artery was evaluated for: interleukin-6, ICAM, VCAM, CD40, NFKB, TNF-alpha and IFN-gamma by immunohistochemistry. A total of 176 tissue samples were grouped for analysis in: A1- arteries with stent (n = 38); A2- native arteries from patients with stent in another artery (n = 68); and A3- arteries without stent from controls undergoing routinely CABG surgery (n = 70). A significance level of 0.05 was adopted. RESULTS: Patients with stent showed higher TNF (p = 0.03) and lower CD40 gene expression (p = 0.01) in peripheral blood cells than controls without stent. In coronary artery samples, the TNF-alpha protein staining was higher in the group A1, not only in the intima-media layer (5.16 ± 5.05 vs 1.90 ± 2.27; p = 0.02), but also in the adipose tissue (6.69 ± 3.87 vs 2.27 ± 4.00; p < 0.001). Furthermore, group A1 had a higher interleukin-6 protein staining in adipose tissue than group A3 (p = 0.04). CONCLUSION: We observed a persistently higher systemic TNF expression associated with exacerbated TNF-alpha and interleukin-6 local production in patients with stents. This finding may contribute to a worse clinical outcome.

RESUMO

O diabetes mellitus (DM) é um importante e crescente problema de saúde, sendo que a doença aterosclerótica é uma importante comorbidade. Além do uso de fármacos, a prevenção da aterosclerose envolve mudança do estilo de vida como exercícios, nutrição, controle do peso e interrupção do tabagismo. O uso da aspirina possui papel bem estabelecido na prevenção secundária da doença cardiovascular (DCV) em pacientes com DM2, porém, o seu uso na prevenção primária permanece controverso e ainda com estudos em andamento. O objetivo desse estudo consistia em realizar uma revisão na literatura sobre as principais indicações para o uso da terapia de antiagregação plaquetária nos pacientes diabéticos. Já na prevenção secundária, o uso da aspirina é um consenso e a dupla terapia é indicada após síndromes coronárias agudas. As diretrizes não trazem informações específicas aos pacientes diabéticos, assim como, suas indicações clássicas na anticoagulação.

Diabetes mellitus (DM) is an important and growing health problem, with atherosclerotic disease being an important comorbidity. In addition to the use of drugs, prevention of atherosclerosis involves changes of lifestyle such as exercise, nutrition, weight control, and stopping smoking. The use of aspirin has a well established role in the secondary prevention of cardiovascular disease (CVD) in patients with DM2. However, its use in primary prevention remains controversial, and studies are still in progress. The objective of this study was to carry out a literature review on the main indications for the use of platelet antiaggregation therapy in diabetic patients. In secondary prevention, the use of aspirin is a consensus and dual antiplatelet therapy indicated after acute coronary syndromes. The guidelines do not provide specific information for diabetic patients, or their classic indications for anticoagulation.

RESUMO

The dehiscence after median transesternal sternotomy used as surgical access for cardiac surgery is one of its complications and it increases the patient's morbidity and mortality. A variety of surgical techniques were recently described resulting to the need of a classification bringing a measure of objectivity to the management of these complex and dangerous wounds. The different related classifications are based in the primary causal infection, but recently the anatomical description of the wound including the deepness and the vertical extension showed to be more useful. We propose a new classification based only on the anatomical changes following sternotomy dehiscence and chronic wound formation separating it in four types according to the deepness and in two sub-groups according to the vertical extension based on the inferior insertion of the pectoralis major muscle.

A deiscência após a esternotomia transesternal mediana utilizada em cirurgia cardíaca é uma de suas complicações e provoca o aumento da morbidade e mortalidade dos pacientes. Várias técnicas cirúrgicas têm sido descritas para o seu tratamento, o que contribuiu para aumentar a importância da classificação destas deiscências. Os métodos de classificação inicialmente descritos se baseavam na infecção do sítio cirúrgico, entretanto, é cada vez mais clara a relevância da descrição exata da localização e a extensão da área cruenta resultante como parâmetros para definição da técnica cirúrgica a ser escolhida. Neste relato é sugerida uma nova classificação baseada somente nas alterações anatômicas das feridas que as classifica em quatro tipos, de acordo com a profundidade, e em dois subgrupos, de acordo com a sua extensão vertical, tendo como referência a inserção da margem inferior do músculo peitoral maior.
