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

ObjectiveTo introduce a new technique to create a pulmonary valve biorifice for reconstruction of right ventricular outflow tract in tetralogy of Fallot (TOF),and to summarize its initial clinical experience and therapeutic effect.MethodsThe new technique regarding reconstruction of right ventricular outflow tract with a pulmonary valve biorifice was used in a total of 53 TOF cases (the observation group).The conventional technique regarding reconstruction of right ventricular outflow tract was used in other 50 TOF cases (the control group).The clinical dates of all cases were reviewed retrospectively.ResultsThe ages,weights,cardiopulmonary bypass time,cardiac arrest time,as well as the post operation ventilation support time were not different significantly between two groups.Compared with the contrul group,patients from the observation group had shorter duration of ICU stay.After operation,in the observation group,only 2 cases had large amount of pleural effusion,1 case meddle,and 8 cases little amount of pleural effusion; whereas,in the control group,the corresponding numbers were 1,5 and 17,respectively.At the time point of 1 week after operation,all patients were rechecked by echocardiography,no pulmonary valve stenosis was found.Moderate pulmonary valve regurgitation was found in 8 cases,mild regurgitation in 15 cases from the observation group; and severe regurgitation in 3 cases,moderate regurgitation in 17 cases,and mild regurgitation in 16 cases from the control group.A total of 33 cases from the observation group were rechecked at the time point of half year after operation,and moderate - mild pulmonary regurgitation were found in 3 cases.A total of 18 cases of them were rechecked 1 - year latter,no pulmonary regurgitation was found.ConclusionsThe new technique to create pulmonary valve biorifice can reduce the pulmonary valve regurgitation and postoperative pleural effusion,and improve the early outcomc.
