Resumo Fundamentos: A disfunção erétil (DE) e a doença arterial coronariana (DAC) compartilham os mesmos fatores de risco e as associações entre DE, qualidade de vida (QV) e DAC têm sido motivo de estudos recentes. Objetivo: Avaliar se a DE está associada a piora da QV em pacientes com DAC. Métodos: Estudo transversal, multicêntrico, prospectivo e analítico, realizado de dezembro de 2014 a abril de 2016, que recrutou 304 homens (idade média: 57 ± 9,9 anos) com diagnóstico clínico de DAC. A QV foi avaliada através do Short Form-36 e a DE pelo Índice Internacional de Função Erétil. Foram realizadas análises estatísticas descritiva e analítica, sendo que o teste não paramétrico Kruskal-Wallis foi usado para analisar se existem diferenças significativas em cada domínio de qualidade de vida quando se comparam os diferentes tipos de DE. Para todos os testes, valor de p ≤ 0,05 foi considerado significante. Resultados: A prevalência de DE foi de 76,3%. As medianas e percentis 25 e 75 de cada domínio de qualidade de vida de acordo com a ausência de DE, DE leve, leve a moderada, moderada e grave, respectivamente, foram: Capacidade funcional: 85 (63-100), 75 (50-95), 60 (32-85), 55 (35-75), 50 (30-70), p < 0,001; Aspectos físicos: 87 (0-100), 40 (0-100), 0 (0-100), 0 (0-31), 0 (0-12), p < 0,001; Dor: 72 (51-100), 66 (51-100), 74 (51-100), 62 (51-100), 51 (31-62), p = 0,001; Estado geral de saúde: 77 (62-87), 72 (57-77), 67 (55-82), 67 (59-75), 52 (37-68), p < 0,001; Vitalidade: 75 (60-85), 65 (50-75), 65 (55-75), 60 (43-75), 50 (32-65), p < 0,001; Aspectos sociais: 87 (62-100), 87 (62-100), 87 (68-100), 75 (62-100), 75 (50-93), p = 0,139; Aspectos emocionais: 100 (58-100), 100 (33-100), 100 (33-100), 100 (0-100), 0 (0-100), p = 0,001; Saúde mental: 80 (67-89), 72 (60-84), 72 (66-80), 68 (58-80), 56 (50-74), p < 0,001. Conclusões: A prevalência de disfunção erétil foi elevada. A DE esteve associada a piora da QV em pacientes com DAC.

Abstract Background: Erectile dysfunction (ED) and coronary artery disease (CAD) share the same risk factors and the associations between ED, quality of life (QoL) and CAD have been the subject of recent studies. Objective: To evaluate whether ED is associated with worsening QoL in patients with CAD. Methods: A cross-sectional, multicenter, prospective and analytic study was carried out from EDcember 2014 to April 2016, which recruited 304 men (mean age: 57 ± 9.9 years) with clinical diagnosis of CAD. QoL was assessed using Short Form-36 and ED by the International Erectile Function InEDx. EDscriptive and analytical statistical analyzes were performed, and the Kruskal-Wallis non-parametric test was used to test whether there are significant differences in each quality of life domain when comparing different types of ED. For all tests, p ≤ 0.05 was consiEDred significant. Results: The prevalence of ED was 76.3%. The median and percentiles 25 and 75 of each life quality domain according to the absence of ED; mild ED, mild to moderate, moderate and severe ED and severe ED, respectively, were: Functional capacity: 85 (63-100), 75 (50 -95), 60 (32-85), 55 (35-75), 50 (30-70), p < 0.001; Physical aspects: 87 (0-100), 40 (0-100), 0 (0-100), 0 (0-31), 0 (0-12), p < 0.001; Pain: 72 (51-100), 66 (51-100), 74 (51-100), 62 (51-100), 51 (31-62), p = 0.001; General state of health: 77 (62-87), 72 (57-77), 67 (55-82), 67 (59-75), 52 (37-68), p < 0.001; Vitality: 75 (60-85), 65 (50-75), 65 (55-75), 60 (43-75), 50 (32-65), p < 0.001; Social Aspects: 87 (62-100), 87 (62-100), 87 (68-100), 75 (62-100), 75 (50-93), p = 0.139; Emotional Aspects: 100 (58-100), 100 (33-100), 100 (33-100), 100 (0-100), 0 (0-100), p = 0.001; Mental health: 80 (67-89), 72 (60-84), 72 (66-80), 68 (58-80), 56 (50-74), p < 0.001. Conclusions: The prevalence of erectile dysfunction was high. ED was associated with worsening of QoL in patients with CAD.

FUNDAMENTO: Não há consenso sobre o impacto do implante de stent sobre a função endotelial no longo prazo. Há relatos de disfunção endotelial aumentada com stent com sirolimus quando comparado com o stent metálico convencional (BMS). OBJETIVO: Este estudo visa a avaliar o impacto do BMS e o efeito do sirolimus por via oral sobre a função endotelial. MÉTODOS: Quarenta e cinco pacientes foram randomizados em três grupos: BMS + altas doses de sirolimus oral (dose inicial de 15 mg, seguida de 6 mg/dia durante quatro semanas); BMS + baixa dose de sirolimus (6 mg, seguida de 2 mg por dia durante quatro semanas) e BMS sem sirolimus. Mudanças na vasoconstrição ou vasodilatação, em um segmento de 15 milímetros começando pelo extremo distal do stent em resposta a acetilcolina e nitroglicerina, foram avaliadas por angiografia quantitativa. RESULTADOS: Os grupos apresentaram características angiográficas semelhantes. A variação percentual de diâmetro em resposta a acetilcolina foi semelhante em todos os grupos, nos dois momentos (p = 0,469). Quatro horas após o implante de stent, o segmento alvo apresentou uma disfunção endotelial que se manteve após oito meses em todos os grupos. Em todos os grupos, a vasomotricidade independente de endotélio em resposta a nitroglicerina foi semelhante, às quatro horas e aos oito meses, com diâmetro do segmento alvo aumentado após a infusão de nitroglicerina (p = 0,001). CONCLUSÃO: A disfunção endotelial esteve igualmente presente no segmento distal de 15 milímetros do segmento tratado, às 4 horas e aos 8 meses após implante do stent. O sirolimus administrado por via oral durante quatro semanas para evitar a reestenose não afetou o estado de vasomotricidade endotélio dependente e independente.

BACKGROUND: There is no consensus regarding the impact of stenting on long-term endothelial function. There have been reports of increased endothelial dysfunction with sirolimus-eluting stents as compared to bare metal stenting (BMS). OBJECTIVE: This study aims to assess the impact of BMS and the effect of oral sirolimus on endothelial function. METHODS: Forty-five patients were randomized into three groups: BMS + high-dose oral sirolimus (initial dose of 15 mg, followed by 6 mg/day for four weeks); BMS + low-dose sirolimus (6 mg followed by 2 mg daily for four weeks); and BMS without sirolimus. Changes in vasoconstriction or vasodilation in a 15 mm segment starting at the distal stent end in response to acetylcholine and nitroglycerin were assessed by quantitative angiography. RESULTS: The groups had similar angiographic characteristics. The percent variation in diameter in response to acetylcholine was similar in all groups at the two time points (p = 0.469). Four hours after stenting, the target segment presented an endothelial dysfunction that was maintained after eight months in all groups. In all groups, endothelium-independent vasomotion in response to nitroglycerin was similar at four hours and eight months, with increased target segment diameter after nitroglycerin infusion (p = 0.001). CONCLUSION: The endothelial dysfunction was similarly present at the 15 mm segment distal to the treated segment, at 4 hours and 8 months after stenting. Sirolimus administered orally during 4 weeks to prevent restenosis did not affect the status of endothelium-dependent and independent vasomotion.

OBJETIVO: Avaliar a prevalência da doença arterial coronariana (DAC) em população de pacientes diabéticos tipo 1, nefropatas, em programa de diálise e candidatos a transplante duplo (rim e pâncreas). MÉTODOS: De janeiro/2000 a julho/2002, foram submetidos a cinecoronariografia, como protocolo de avaliação para transplante duplo, 58 pacientes diabéticos tipo 1. Doença arterial coronariana foi definida como qualquer irregularidade nas artérias coronárias, e classificada, de acordo com a grau de estenose luminal, em leve (<30%), moderada (>30 a 70%) e grave (>70%). RESULTADOS: A idade dos pacientes foi 34 ± 12 anos, sendo que 32 (55%) eram homens. Nenhum paciente tinha história de angina ou infarto agudo do miocárdio. Os principais fatores de risco para a doença foram hipertensão arterial sistêmica em 93%, dislipidemia em 38%, historia familiar em 25% e tabagismo 20%. O tempo médio de duração do diabetes foi 20,8 ± 9 anos, o tempo de diálise de 26 ± 9 meses. A coronariografia revelou doença arterial coronariana em 42 (72%) pacientes, sendo 20 (34%) discreta, 9 (16%) moderada e 13 (22%) grave. CONCLUSÃO: Pacientes diabéticos tipo 1 em programa de diálise e candidatos a transplante duplo têm elevada prevalência de doença arterial coronariana, tornando-se marcante a observação de que esses pacientes não apresentavam sintomas da doença.

OBJECTIVE: To assess the prevalence of coronary artery disease (CAD) in a population of type I diabetic, nephropathic patients in a dialysis program and candidates for double transplantation (kidney and pancreas). METHODS: From January 2000 to July 2002, 58 type I diabetic patients underwent coronary cineangiography as part of an assessment protocol for double transplantation. Coronary artery disease was defined as any irregularity in the coronary arteries and was classified according to the degree of luminal stenosis as mild (< 30%), moderate (> 30 to 70%), and severe (> 70%). RESULTS: The mean age of the patients was 34 ± 12 years, and 32 (55%) were men. No patient had a history of angina or acute myocardial infarction. The major risk factors for the disease were systemic arterial hypertension in 93% of the patients, dyslipidemia in 38%, familial history in 25%, and smoking in 20%. The mean duration of diabetes was 20.8 ± 9 years, and the duration of dialysis was 26 ± 9 months. Coronary angiography revealed coronary artery disease in 42 (72%) patients, which was mild in 20 (34%) patients, moderate in 9 (16%), and severe in 13 (22%). CONCLUSION: Patients with type I diabetes in a dialysis program and candidates for double transplantation had an elevated prevalence of coronary artery disease. It is worth noting that those patients had no symptoms of the disease.

OBJECTIVE: To identify risk factors for acute myocardial infarction during the postoperative period after myocardial revascularization. METHODS: This was a case-control study paired for sex, age, number, type of graft used, coronary endarterectomy, type of myocardial protection, and use of extracorporeal circulation. We assessed 178 patients (89 patients in each group) undergoing myocardial revascularization, and the following variables were considered: dyslipidemia, systemic hypertension, smoking, diabetes mellitus, previous myocardial revascularization surgery, previous coronary angioplasty, and acute myocardial infarction. RESULTS: Baseline clinical characteristics did not differ in the groups, except for previous myocardial revascularization surgery, prevalent in the case group (34 patients vs. 12 patients; p = 0.0002). This was the only independent predictor of risk for acute myocardial infarction in the postoperative period, based on a multivariate logistic regression analysis (p=0.0001). Mortality and the time of hospital stay of the case group were significantly higher (19.1% vs. 1.1%; p<0.001 and 15.7 days vs. 10.6 days; p<0.05 respectively) than those of the control. CONCLUSION: Only previous myocardial revascularization was an independent predictor of acute myocardial infarction in the postoperative period, based on multivariate logistic regression analysis.

OBJETIVO: Avaliar a evolução hospitalar de pacientes submetidos a implante percutâneo de stent nas artérias carótidas. MÉTODOS: De agosto/96 a abril/01 estudamos 86 pacientes que apresentavam lesão obstrutiva na artéria carótida >70% e foram tratados com implante percutâneo de stent. Mensuramos o sucesso do implante, do procedimento, os tipos de stents utilizados, a mortalidade e as complicações neurológicas. RESULTADOS: O sucesso do implante foi alcançado em 98,9%, enquanto o procedimento em 91.8%. O stent mais utilizado foi o Wallstent em 73 (77%) pacientes. Houve 3 (3,2%) acidentes vasculares cerebrais transitórios, 1 (1,1%) acidente vascular cerebral menor e 3 (3,2%) acidentes vasculares cerebrais maiores. A mortalidade hospitalar foi de 1 (1,1%) paciente. CONCLUSÃO: O alto índice de sucesso no implante de stents (98,9%), aliado à baixa taxa associada de acidente vascular cerebral/morte de (4,2%) demonstraram a eficiência e segurança do implante percutâneo de stent nas artérias carótidas.

OBJECTIVE: To assess the in-hospital evolution of patients undergoing percutaneous stent placement in the carotid arteries. METHODS: From August 1996 to April 2001, we studied 86 patients with carotid arterial obliterative lesions > 70% who were treated with percutaneous stent placement in the carotid arteries. We assessed the rate of success of the implantation and of the procedure, the types of stents used, mortality rate, and neurological complications. RESULTS: Successful implantation was obtained in 98.9% of the cases, and the procedure was successful in 91.8%. The Wallstent was the most frequently used stent (73 patients - 77%). Cerebral strokes occurred as follows: 3 (3.2%) transient ischemic attacks, 1 (1.1%) minor stroke, and 3 (3.1%) major strokes. One (1.1%) patient died during hospitalization. CONCLUSION: The high rate of success of stent implantation (98.9%) in addition to the low rate of cerebral stroke/death (4.2%) showed the efficiency and safety of percutaneous stent placement in carotid arteries.
