RESUMO
Hemorrhagic transformation is a complex phenomenon where brain tissue bleeds, which could be associated or not to an increase in the neurological deficit after the acute ischemic stroke. The aim of our study was to evaluate clinical predictors of hemorrhagic transformation in patients with non-lacunar ischemic stroke. We performed a prospective analysis of the clinical records and images of patients with non-lacunar ischemic stroke. Demographics, vascular risk factors, previous medications and the information of the event in patients with and without hemorrhagic transformation were here compared. We included in this study 747 patients with non-lacunar stroke, the mean age was 77 ± 11 years and 61% were females. In the univariate analysis, the age, a history of hypertension, atrial fibrillation, chronic kidney disease and the previous use of oral anticoagulation resulted statistically significant. In the multivariate analysis of logistic regression adjusted by age and vascular risk factors: the age > 80 years (OR 3.6, CI 95% 1.8-7.6), the pulse pressure > 60 mmHg at admission (OR 5.3, CI 95% 3.2-9.1), the chronic kidney disease (OR 3, CI 95% 2.5-3.8) and the presence of previous atrial fibrillation (OR 3.5, CI 95% 2.1-6.1) were associated with and increased risk of hemorrhagic transformation. The predictors of hemorrhagic transformation in our cohort showed a relationship with severe vascular illness. The identification of these patients could influence therapeutic decisions that could increase the risk of hemorrhagic transformation.

We compared the use of evidence-based secondary prevention drugs for coronary artery disease at hospital discharge and 3 years of follow-up in a group of patients associated to an integrated network of health services. We conducted a retrospective group study that included 125 patients under 80 years of age who were hospitalized for acute coronary syndrome. McNemar's test was used to compare values at baseline and 3 years. The mean age of of participants was 63.7 years (SD ± 10.08) and 65.6% (95% CI 56.6-73.9) of male sex. The average follow-up time was 2.94 years (SD ± 0.25). The use of secondary prevention drugs for coronary heart disease decreased at 3 years of follow-up: anti-platelet 97.6 to 88.0% (p = 0.012), beta-blockers 94.4 to 84.8% (p = 0.021) and statins 83.7 to 91.2% (p = 0.035). Patients medicated with a combination of anti-platelet, beta blockers and statins showed a decrease from 86.4 to 66.3% (p < 0.0001). It is necessary to study the causes for the decreased adherence to long-term cardio-protective drugs.

La transformación hemorrágica es un fenómeno complejo en el que el tejido cerebral isquémico sangra; este proceso puede asociarse o no a un deterioro del estado neurológico inicial. El objetivo de nuestro estudio fue evaluar los predictores clínicos de trasformación hemorrágica en los pacientes con accidente cerebrovascular isquémico no lacunar. Se analizaron las historias clínicas y las imágenes de pacientes con infarto cerebral no lacunar incluidos prospectivamente en un programa de prevención secundaria. Se compararon datos demográficos, factores de riesgo vascular, medicación previa y datos del evento de los pacientes con transformación hemorrágica y sin ella. Se incluyeron 747 pacientes, la edad promedio fue de 77 ± 11 años, 61% mujeres. En el análisis univariado, la edad, el antecedente de hipertensión arterial, la fibrilación auricular, la insuficiencia renal crónica y la anticoagulación oral previa se relacionaron significativamente con la presencia de transformación hemorrágica. En el análisis multivariado de regresión logística ajustado por edad y factores de riesgo vascular, resultaron predictores de transformación hemorrágica: la edad > 80 años (OR 3.6; IC 95% 1.8-7.6), la presión de pulso > 60 mmHg al ingreso (OR 5.3; IC 95% 3.2-9.1), la insuficiencia renal crónica (OR 3; IC 95% 2.5-3.8) y el antecedente de fibrilación auricular (OR 3.5; IC 95% 2.1-6.1). En nuestra cohorte los predictores clínicos de conversión hemorrágica del infarto cerebral muestran una relación con la gravedad de la enfermedad vascular. La identificación de estos pacientes influenciaría en la toma de decisiones terapéuticas que pudieran incrementar el riesgo de transformación hemorrágica.

As population grows old, the number of persons at risk of cardiovascular events also grows. Though octogenarians form a small percentage of the general population their absolute risk of coronary and cerebrovascular disease is high, but there is still some doubt as to whether high plasma cholesterol levels increase vascular risk in this age group, as published data are conflicting. There is evidence that elevated plasma cholesterol increases the risk of coronary artery disease in older adults, and an inverse linear relationship was found between HDL cholesterol levels and the risk of mortality from ischemic heart disease in all age groups. The relationship between total plasma cholesterol and the risk of death from ischemic stroke is weak in younger populations and is even lower in people between 70 and 89 years, and is inverse for hemorrhagic stroke. However, studies showed that statin treatment lowers the risk of ischemic stroke, independently of age. Statins are underused in the elderly, perhaps because of lack of perception of the real vascular risk of older adults, concerns about statin efficacy or safety in this population, or the increase of comorbidities and polypharmacy which could affect adherence to drug-treatment. Trials designed to address this issues are urgently needed, in order to be able to make evidence-guided decisions on lipid management of the elderly.

Se comparó la adherencia a la prevención secundaria de enfermedad coronaria mediante el uso indicado de fármacos de probada eficacia, al momento del egreso hospitalario y a 3 años de seguimiento, en una cohorte de pacientes afiliados al Plan de Salud del Hospital Italiano. Se realizó un estudio de cohorte retrospectivo que incluyo 125 pacientes menores de 80 años de edad, afiliados a una red integrada de salud, con internación por síndrome coronario agudo. En el análisis se utilizó el test de McNemar. La edad media de los participantes fue 63.7 años (DS 10.08) y el 65.6% (IC95% 56.6-73.9) fue de sexo masculino. El 76.8% (IC95% 68.4-83.9) presentó como evento calificante un síndrome coronario agudo sin elevación del segmento ST. El tiempo de seguimiento promedio fue 2.94 años (DS 0.25). Se observó que el uso de drogas de probada eficacia en la prevención secundaria de enfermedad coronaria descendió entre el momento del egreso hospitalario y los 3 años de seguimiento: antiagregantes de 97.6 a 88.0% (p = 0.012); beta-bloqueantes de 94.4 a 84.8% (p = 0.021); estatinas 91.2 a 83.7% (p = 0.035). Uso combinado de antiagregantes, betabloqueantes y estatinas de 86.4 a 66.3% (p < 0.0001). Es necesario estudiar las causas de la disminución de la adherencia a drogas cardioprotectoras a largo plazo.(AU)
