Background: The relationship between erectile dysfunction and risk factors of atherosclerosis has been confirmed by a number of previous investigations. There are also plausible pathophysiological mechanisms explaining the observed association. One of the tested hypotheses in our work was the assumption that risk factors of atherosclerosis would be more prevalent in men with erectile dysfunction than in controls selected from the representative sample of the Czech population. Our work did not confirm this hypothesis. Most likely explanation can be greater representation of younger-middle aged men in our group than in the Czech post-Monica study in which the age distribution was equal. On the other hand authors of the Czech post-Monica study admit worse compliance in younger participants of their survey. Nevertheless, the risk factors of atherosclerosis occur very frequently in males with erectile dysfunction. Results: In our group mean cardiovascular risk calculated according to the SCORE chart was 3.39% (±3,39). In the Czech post-MONICA study conducted between 2007 and 2008 the mean SCORE risk reached 2.47%. There was a trend, though not statistically significant, towards direct relationship between the severity of ED and the SCORE CVD risk. Asymptomatic atherosclerosis was detected in 56.25% of our study...

El elevado riesgo tromboembólico y hemorrágico en la fibrilación auricular (FA) es altamente heterogéneo y condiciona la morbi-mortalidad de la FA. La anticoagulación oral previene eventos trombóticos y mortalidad, pero conlleva ciertos riesgos. Por ello, los pacientes son estratificados según escalas de riesgo, que se intentan refinar adicionando otros marcadores. Para evaluar su utilidad pronóstica, puntuamos según las escalas CHA2DS2-VASc y HAS-BLED a pacientes consecutivos, anticoagulados de forma estable. Además determinamos los títulos de troponina T (hsTnT) e interleukina 6 ultrasensibles (hsIL6), y el índice tobillo brazo (ITB). La escala CHA2DS2-VASc predice eventos cardiovasculares y mortalidad; la escala HAS-BLED no solo es útil en la valoración del riesgo hemorrágico sino que también muestra valor predictivo de eventos cardiovasculares y mortalidad. Los valores de hsTnT y los de hsIL6 añaden información pronóstica, mejorando el índice de discriminación integrado de ambas escalas. El ITB resultó predictor de eventos trombóticos y hemorrágicos / The high thrombotic risk determines the atrial fibrillation morbi-mortality. Oral anticoagulation results in stroke and mortality prevention, at the expense of bleeding-related risk. These risks are highly heterogeneous, reason why patients are stratified according to risk scores, refined by specific biomarkers. In order to evaluate their prognostic value, we recruited consecutive patients, steady on oral anticoagulation, in whom CHA2DS2-VASc and HAS-BLED scores were calculated. In addition levels of high sensitivity troponin T and interleukin 6 (hsTnT and hsIL6 respectively) were determined, and the ankle brachial index (ABI) measured. The CHA2DS2-VASc score predicts cardiovascular events and mortality; HAS-BLED score is not only useful to assess bleeding risk but also shows predictive value for cardiovascular events and mortality. In addition levels of both hsTnT and hsIL6 provided prognostic information, improving the integrated discrimination index of both scores. Abnormal ABI was an independent predictor for all-cause mortality and major bleeding.

Background:There is controversial evidence with regard to the significance of peripheral arterial disease (PAD) as an indicator for future stroke risk. We aimed to quantify the risk increase for mortality and morbidity associated with PAD. Methods:In an open, prospective, noninterventional cohort study in the primary care setting, a total of 6,880 unselected patients ≧65 years were categorized according to the presence or absence of PAD and followed up for vascular events or deaths over 5 years. PAD was defined as ankle-brachial index (ABI) <0.9 or history of previous peripheral revascularization and/or limb amputation and/or intermittent claudication. Associations between known cardiovascular risk factors including PAD and cerebrovascular mortality/events were analyzed in a multivariate Cox regression model. Results:During the 5-year follow-up [29,915 patient-years (PY)], 183 patients had a stroke (incidence per 1,000 PY: 6.1 cases). In patients with PAD (n = 1,429) compared to those without PAD (n = 5,392), the incidence of all stroke types standardized per 1,000 PY, with the exception of hemorrhagic stroke, was about doubled (for fatal stroke tripled). The corresponding adjusted hazard ratios were 1.6 (95% confidence interval, CI, 1.1–2.2) for total stroke, 1.7 (95% CI 1.2–2.5) for ischemic stroke, 0.7 (95% CI 0.2–2.2) for hemorrhagic stroke, 2.5 (95% CI 1.2–5.2) for fatal stroke and 1.4 (95% CI 0.9–2.1) for nonfatal stroke. Lower ABI categories were associated with higher stroke rates. Besides high age, previous stroke and diabetes mellitus, PAD was a significant independent predictor for ischemic stroke. Conclusions:The risk of stroke is substantially increased in PAD patients, and PAD is a strong independent predictor for stroke. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Introdução: Inúmeros estudos estabeleceram correlações entre o índice tornozelo-braço (ITB), um marcador de aterosclerose subclínica, e o prognóstico cardiovascular em diferentes populações. No entanto, poucos estudos avaliaram a correlação entre os valores do ITB e lesões cardiovasculares e renais, exclusivamente, em pacientes com hipertensão arterial e diabetes. Objetivo: Estudar a prevalência de alterações morfofuncionais cardíacas, carotídeas, retinianas e renais de acordo com a presença ou não de valores de ITB alterados (ITB <= 0,9 ou ITB > 1,4) em pacientes hipertensos com diabetes tipo 2. Métodos: Foram incluídos no estudo 99 pacientes hipertensos diabéticos com idade entre 50 e 80 anos. A aferição do ITB foi realizada em todos os pacientes por método validado e estes foram classificados em Grupo 1 (ITB normal, n = 49) ou Grupo 2 (ITB alterado, n =50). Todos os pacientes foram submetidos, em até 06 meses, à realização de ecodopplercardiograma, ultrassonografia de carótidas, retinografia colorida, aferição da taxa de filtração glomerular (TFG) e da albuminúria de 24h. Os pacientes foram analisados para a ocorrência ou não de um desfecho-composto ecocardiográfico que incluiu alterações morfológicas e funcionais cardíacas relevantes para a prática clínica. Os pacientes dos grupos 1 e 2 foram também comparados quanto à prevalência de placas carotídeas com ou sem repercussão hemodinâmica, TFG < 60 ml/mim/m2, albuminúria de 24h > 30mg e presença ou não de retinopatia. Por fim, foram comparadas as frequências médias das seguintes lesões de órgãos-alvo de ambos os grupos, considerando-se valor unitário para a presença de cada uma delas: hipertrofia do ventrículo esquerdo, retinopatia hipertensiva, TFG < 60 ml/min/m2 e estenose da artéria carótida interna > 50% do seu diâmetro. Resultados: A média de idade dos pacientes foi 65,4 ± 7 anos, sendo 61,6% deles do sexo feminino. A presença de níveis elevados de pressão arterial sistólica (153,4 ± 18 versus 170 ± 26 mmHg), de albuminúria de 24h > 30mg (55,3% versus 82,6%) e de TFG < 60 ml/min/m2 (12,8% versus 33,3%) foi significativamente maior (p < 0.05) entre os pacientes do Grupo 2. O desfecho-composto ecocardiográfico foi mais prevalente no grupo 2 (84,0% versus 59,2%; p = 0,006) e a frequência média de lesões de órgãos-alvo também foi maior nos pacientes do grupo 2 (0,36 ± 0,31 versus 0,19 ± 0,19; p = 0,001). Análise por regressão logística binária revelou que o ITB foi uma das variáveis preditoras independentes para o desfecho-composto ecocardiográfico (OR = 3,43; IC 95% = 1,07 - 11,0; p = 0,04). A partir da análise por regressão linear obteve-se um modelo final no qual o ITB foi uma das três variáveis preditoras independentes para a estimativa da frequência média de lesões de órgãos-alvo com coeficiente beta = 13,22 (1,81 - 24,63), ao lado da idade e do infarto prévio. Conclusão: Nossos dados mostram que valores de ITB alterados estão associados à maior prevalência de lesões em órgãos-alvo, principalmente alterações ecocardiográficas, em pacientes com hipertensão arterial e diabetes / Introduction: A lot of studies have established strong correlations between the ankle-brachial index (ABI), a marker of subclinical atherosclerosis and cardiovascular prognosis in different populations. However, few studies have assessed the correlation between the values of the ABI and cardiovascular and renal lesions in patients with hypertension and diabetes. Objective: To study the prevalence of cardiac, carotid, renal and retinal morphological and functional changes according to the presence or not of altered ABI values (ABI <= 0.9 or ABI > 1.4) in hypertensive patients with type 2 diabetes. Methods: It was included 99 diabetic hypertensive patients aged between 50 and 80 years. The measurement of the ABI was performed in all patients by validated method and they were classified in Group 1 (normal ABI, n = 49) or group 2 (altered ABI, n = 50). All patients were submitted, up to 6 months, to Doppler echocardiography, carotid ultrasound, color retinography, assessment of glomerular filtration rate (GFR) and 24h albuminuria. Patients were analyzed for the occurrence or not of a composite echocardiographic outcome which included morphological and functional cardiac alterations relevant to clinical practice. Patients in groups 1 and 2 were compared regarding the prevalence of carotid plaques with or without hemodynamic repercussion, TFG < 60 ml/min/m2, 24h albuminuria > 30 mg and the presence or not of retinopathy. Finally, we compared the prevalence of mean frequency of the following end-organ lesions of both groups, considering unit value for each one: left ventricular hypertrophy, hypertensive retinopathy, TFG < 60 ml/min/m2 and internal carotid artery stenosis > 50%. Results: The mean age of the patients was 65.4 ± 7 years, with 61.6% of them female. The presences of elevated levels of systolic blood pressure (153.4 ± 18 versus 170.0 ± 26 mmHg), of 24h albuminuria > 30 mg (55.3% versus 82.6%) and TFG < 60 ml/min/m2 (12.8% vs. 33.3%) were significantly greater (p < 0.05) among the patients of Group 2. The composite echocardiographic outcome was more prevalent in Group 2 (84.0% versus 59.2%, p = 0.006) and the average frequency of subclinical injury of target organs was also greater in patients of Group 2 (0.36 ± 0.31 versus 0.19 ± 0.19; p = 0.001). Binary logistic regression analysis revealed that the ABI was one of the independent predictors of composite echocardiographic outcome (OR = 3.43; IC 95% = 1.07 - 11.0; p = 0.04). From the linear regression analysis it was obtained a final model in which the ABI was one of three independent predictors for the estimation of the average frequency of end-organ damage with ? coefficient = 13.22 (1.81-24.63), besides age and previous myocardial infarction. Conclusion: Our data demonstrates that changed ABI values are associated with higher prevalence of subclinical end-organ lesions, principally changes in echocardiographic parameters, in patients with hypertension and diabetes
