- Abstract
High aluminum loading incorporation in the SBA-15 silica structure was investigated. Different Si/Al molar ratios (15, 10, and 2) were evaluated. The SBA-15 and the aluminum-containing materials (Al-SBA-15) were prepared by the “pH adjusting” method with modifications. The mesoporous structure of the materials was demonstrated by the type IV isotherms. The SBA-15 pore changed from a cylindrical to a slit-like structure in the presence of higher aluminum content. X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) pointed out that the structural order is compromised in the presence of a higher aluminum load in the Al-SBA-15 materials, although the mesoporous structure was preserved. Higher Al loading increases the total quantity of Lewis acid sites as well as generates Brönsted acid sites. CO adsorption FTIR spectroscopy suggests aluminum incorporation into the SBA-15 and generation of acid sites. The Si–O–Al linkage in the aluminum-containing materials was corroborated by UV–Vis DRS due to the presence of a peak centered at 241 nm related to the Al-O bond, which is ascribed to four-coordinated framework aluminum in the SBA-15 structure. XPS spectra of Al 2p suggested that the Al species are less oxidized than the Al2O3 phase giving some indication of Al incorporation into the SBA-15 framework. 27Al MAS NMR results revealed that the aluminum species are in a tetrahedral oxygen coordination environment for Al-SBA-15 with Si/Al molar ratios of 15 and 10. Aluminum species in both tetrahedral and octahedral environments were evidenced for Al-SBA-15 with a Si/Al molar ratio of 2., Peer Reviewed, Postprint (author's final draft)

- Abstract
Nowadays, many industrial processes depend on fossil resources to obtain high-added-value chemical compounds, bringing with it significant environmental deterioration. Therefore, the implementation of green alternatives considering the use of biomass residues in hydrogen-free catalytic processes is of great relevance. In this work, a set of copper catalysts prepared by impregnating SBA-15 and Zr-SBA-15 (different Si/Zr ratios) supports were catalytically tested in the glycerol dehydration. The copper catalysts were characterized by ICP, SEM-EDS, N2 physisorption, XRD, HRTEM, FT-IR, UV–Vis DRS, XPS, H2-TPR, N2O chemisorption, and TPO analyses. ICP revealed a suitable agreement between nominal and actual copper content in the catalysts. Copper catalysts exhibited textural and structural properties of mesoporous materials which are affected by increasing Zr content. Pyridine FT-IR indicated that copper catalysts with lower Zr content possess the highest values of Lewis acid sites. Higher Zr content makes the copper reduction more difficult, and the dispersion is unfavored. The catalytic system was studied using an 80% wt. aqueous glycerol solution in inert conditions at 220 °C without diffusional limitations according to the Weisz–Prater and Mears criteria. The highest values of specific initial reaction rate and rate constant were obtained in catalysts with zero (Cu/B catalyst, 1.50¿×¿10-3 molgl/min gcat, 7.79¿×¿10-4 min-1) and low (Cu/B10 catalyst, 1.53¿×¿10-3 molgl/min gcat, 8.27¿×¿10-4 min-1) Zr loading. Hydroxyacetone (HA) and 1,2-propanediol (1,2-PDO) were the main formed products. HA formation reached values greater than 90% selectivity in the first minutes of the reaction, while 1,2-PDO achieved a progressive evolution over time up to 9% selectivity. Initial formation rates of HA (3.29¿×¿10-4 molHA/min gcat) and 1,2-PDO (2.13¿×¿10-5 mol1,2-PDO/min gcat) were optimized on the Cu/B10 catalyst containing the lowest Zr load. 1,2-PDO generation in the absence of ext, Peer Reviewed, Postprint (author's final draft)

- Abstract
SBA-15 is a material with interesting characteristics associated with the size, order, uniformity, and pores distribution. However, the absence of acidity in SBA-15 restricts its applications as a potential acid catalyst in the industry for the large-scale production of fuels and chemicals. Mesoporous SBA-15 modified by the incorporation of heteroatomic species can be a good strategy to include acidity and prepare an efficient catalyst. In this work, we present a comparative study in the preparation of SBA-15 and Zr-SBA-15 mesoporous materials with high zirconium loads (Si/Zr ¿= ¿10, 5, and 2) using direct-synthesis and pH-adjusting approaches with a low crystallization temperature of 60 ¿°C. The materials were characterized using XRPD, HRTEM, ICP, SEM-EDS, XPS, DRS UV-VIS, FT-IR, NH3-TPD, in situ FT-IR with pyridine probe, and N2-physisorption. Characterization by ICP and SEM-EDS indicated that the Si/Zr molar ratio of Zr-materials prepared by the pH adjustment better matched the nominal values. N2-physisorption showed that the mesoporosity of the materials was preserved even at the high Zr load. XRPD and HRTEM pointed out that Zr-SBA-15 materials prepared by the pH adjustment showed a higher level of ordering in the porous network. Regardless of the synthesis approach, the presence of a higher Zr load caused a loss in the structural ordering. It must be highlighted that the high-resolution XPS spectra of Zr 3d suggested the formation of Si–O–Zr bonds giving some indication of Zr incorporation into the SBA-15 framework. The formation of Si–O–Zr linkage in the Zr-materials was also corroborated by DRS UV-VIS due to the presence of a blue shift in the absorption edge for both series of the Zr-SBA-15 materials. NH3-TPD and in-situ FT-IR spectroscopy with pyridine probe showed that the presence of Zr species introduces acidity in the SBA-15 and at higher Zr load the Brønsted acidity increased particularly for the Zr-materials prepared by pH adjustment.

Introducción: La hidatidosis es una zoonosis endémica en diferentes zonas de Chile y en la Región de Coquimbo, ligada a la faena de ganado y presencia de perros. Objetivo: Identificar factores de riesgo relacionados con hidatidosis en hogares de estudiantes de enseñanza media de la comuna de Punitaqui. Material: Se realizó un estudio transversal, descriptivo, aplicándose un cuestionario auto-administrado a 274 estudiantes de enseñanza media. Se analizó según zona urbana/rural en cinco dimensiones: conocimientos, saneamiento básico, tenencia de perros, cultivo de vegetales y, tenencia y faena de ganado. Resultados: El 84,6% de los estudiantes urbanos manifestó no haber recibido educación sobre hidatidosis. En zonas rurales, 93,5% señaló poseer perros, promediando 2,95 perros/vivienda (p < 0,001) y 60,3% (p < 0,001) era alimentado con vísceras. En zonas urbanas, 44,4% de los perros no había sido desparasitado. El 66,2% del alumnado declaró poseer ganado caprino y ovino y 64,5% (p < 0,001) de hogares rurales faenaba. La eliminación de vísceras era destinada principalmente para alimentación de perros. Conclusiones: Se presentaron factores de riesgo que favorecen la presencia del parásito, relacionados a la tenencia de perros y crianza y faena de ganado, los que fueron mayoritarios en sectores rurales siendo igualmente altos en zonas urbanas. Background: Hydatidosis is an endemic zoonosis in different areas of Chile, including the Region of Coquimbo, this is linked to the slaughter of cattle and presence of dogs. Objective: To identify risk factors related to hydatidosis in the home of high school students of Punitaqui. Material: A descriptive cross-sectional study was done by the application of a self-administered questionnaire to 274 students of high school. The information was analyzed by urban/rural area in five dimensions: knowledge, basic sanitation, keeping dogs, vegetable growing and cattle slaughtering and possession. Results: 84.6% of urban students reported not having received hydatidosis education. In rural areas, 93.5% reported owning dogs, with an average of 2.95 dogs/home (p < 0.001). In urban areas 44.4% of the dogs had not been dewormed and 60.3% (p < 0.001) was fed with viscera in rural areas. The 66.2% of cattle were goats and sheep and 64.5% (p < 0.001) of rural households did slaught. The main way to eliminate viscera was feeding the dogs. Conclusions: Risk factors that favor the presence of the parasite were present in relation to keeping dogs and cattle breeding and slaughter, which occurred mostly in rural areas, but being also present in urban areas.

Traumatismos del Tobillo ,Postura Humana ,Desórdenes - Abstract
Tesis (Kinesiólogo) El control postural es la capacidad del cuerpo de mantener una alineación correcta del centro de gravedad dentro de la base de sustentación, determinado por el sistema visual, sistema somatosensorial y vestibular. Dentro de los factores que pueden alterar el control postural se encuentran lesiones de tipo neurológica, sensorial y musculo esqueléticas, donde encontramos los esguinces de tobillo, que son una de las patologías más frecuentes en la población sedentaria y deportista, y se ha definido que 2 o más episodios de esguince de tobillo en un periodo de un año genera Inestabilidad Crónica de Tobillo, descrita como una alteración en el control postural dado por un déficit en la estabilidad mecánica, funcional o ambas. Como métodos de tratamiento, estudios revisados han dado cuenta de la utilización de ayudas técnicas externas, como es el caso de Taping y Aso Ankle Brace, que proporcionan una mayor estabilidad y disminuyen la incidencia de volver a generar un esguince. El objetivo de este seminario de titulo es estudiar la influencia de las ayudas técnicas externas sobre el Control Postura1 en personas con Inestabilidad Crónica de Tobillo, medido a través de Posturografía y SEBT. Este seminario es de tipo cuantitativo cuasiexperimental, cuya muestra está constituida por 14 estudiantes universitarios (6 mujeres y 8 hombres), lo cuales fueron incluidos según criterios de inclusión y exclusión. Los participantes fueron evaluados mediante 2 pruebas instrumentadas y un cuestionario de auto reporte. Los datos fueron analizados por el software Graph Pad InSatd, a través de la prueba estadística ANOVA, donde se concluyo que el uso de ayuda técnica externa en situaciones de estabilidad no tiene diferencias significativas en relación al grupo control, y que el uso de Taping tiene diferencias significativas sobre el control postural en pruebas dinámicas en comparación al grupo control. The postiiral control is the body ability of keeping a correct alignment of the gravity center inside the sustentation base, determined by the visual somatosensory and the vestibular system. The factors that can modify the postural control we could find the neurologic, the somatosensory %id musculoskeletal injuries, for instance an ankle sprain, which is one of the most frequent pathologies in the sport and sedentary population; also, there has been confirm that two or more episodes of rinkle sprain in one year provokes Chronic Ankle Instability, which has been described as an alteration in the postural control caused by a deficit in the mechanic or fiinctional stability or even both. ín the case of treatment methods, revised studies have reportcd that the use of external technical assistance, as Taping aiid Aso Ankle Brace, give more stability and rediice the possibilities of suffcring another ankle sprain. This work's objective is to study the influence of the external technical assistance over the postural control in people who suffer from Chronic Ankle Instability, this is measured through postiirography and SEBT. This is work has ri quantitate and quasiexperimental point of vicw and its sample is constituted by 14 university students (6 women and 8 men) who were chosen by inclusion and exclusion criteria. The participants were evaluated using two instrumented tests and one self-report questionnaire; in both cases external technical assistance was used randomly. The results were analyzed by the Graph Pad InSatd software through the ANOVA test. It was concluded that the use of external technical assistance in stability situations does not have a major impact with respect to the control group. On the other hand, the use of Taping has a major impact in the postural control in dynamic tests in relation to control group

Introdución: El acceso radial (AR) ha demostrado reducir las complicaciones vasculares asociadas a la coronariografía y angioplastía coronaria; sin embargo, su rol en la angioplastía primaria (AP) durante el infarto agudo al miocardio con supradesnivel del segmento ST (IAM c/SDST) es muy escasa. En diciembre de 2007, nuestro equipo adoptó esta técnica como primera opción durate la AP Objetivo. Estudiar si el AR durante la AP es tan rápido y seguro como el acceso femoral (AF). Métodos: Utilizando el registro de nuestro laboratorio, analizamos todos los pacientes con IAM c/SDST que fueron tratados con AP en nuestro hospital en el período Septiembre 2005 - Agosto 2009, y luego de identificar los pacientes de acuerdo al AF y AR, comparamos el tiempo "puerta-balón", los resultados an-giográficos, el éxito clínico y las complicaciones relacionadas al acceso. El seguimiento se efectuó a través de las visitas médicas y vía telefónica. Los valores se muestran como promedio ± DS. Resultados: En el periodo estudiado, en 354 (75%) pacientes se utilizó AF y en 118 (25%) el AR. La edad promedio de ambos grupos fue similar, 61±12 años en el grupo con AF vs 62±12 años en AR (p=ns) y no hubo diferencias en las características clínicas de los grupos. El tiempo "puerta-balón" fue 62±37 minutos vs 61±29 minutos en AF y AR respectivamente (p=ns) con una tasa de éxito superior al 94% en ambo grupos. En el grupo de AF hubo 3% de complicaciones vasculares vs 0% en AR. La mortalidad global a 30 días fue 5,1 % en el grupo de AF y de 4,0% en AR (p=ns). Conclusión: El acceso radial para la AP permite abrir la arteria culpable en tiempos similares al AF y con una menor incidencia de complicaciones vasculares. Background: Radial access (RA) has been shown to help reduce vascular complications of coronary ar-teriography and angioplasty (PTCA). However, little experience has been reported with RA to perform primary PTCA in ST elevation acute myocardial infarction (STEMI). Since December 2007, we selected RA as a first option for primary PTCA in STEMI. Aim: to determine whether RA is as effective, safe and expeditious as femoral access (FA) in primary PTCA for STEMI Method: we performed a retrospective review of our database of all patients undergoing primary PTCA in our laboratory from Sept 2005 through August 2009. We compared all patients who had a PTCA using a FA to those in whom the RA was used. The door to balloon time, angiographic results, clinical success rate and complications related to the vascular access were compared between groups. Follow-up was based con clinical visits and phone calls. Values are expressed as mean and SD. Results: 375 patients had an FA (75%) and 118 an RA (25%). Mean age was similar in both groups (61±12 vs 62±12, respectively, NS). Selected clinical characteristics did no differ between groups. Door to balloon time was 62±37 min for FA and 61±29 min for RA (NS). Clinical success rate exceeded 94% in both groups. Vascular complications occurred in 3% in the AF group. No vascular complications were observed in the RA group. Thirty day overall mortality rates were 5.2% in FA and 4.0% in RA (NS). Conclusion: Radial access can be used for primary PTCA in STEMI with similar success rates and lower incidence of vascular complications, when compared to the traditional femoral access.

Myocardial infarction ,Risk factors ,Coronary artery disease - Abstract
Background: Guidelines for the management of unstable angina (UA) and non ST elevation myocardial infarction (NSTEMI) have been issued, however cu-rrent practices are unknown in Chile. Aitn: To evalúate in a prospective cohort of NSTEMI patients the current practices, treatments and risk factors. Material and Methods: Oneyear prospective International non interventional registry, conducted in Chile between January 2005 and November 2006. Results: Two hundred thirty three Chilean NSTEMI patients were enrolled. Mortality was 5.5% at the end ofthe follow-up. Mean age was 61.6 years, and 30.6% were female. Most of the patients had at least one risk factor (98%): hypertension (84%), previous myocardial infarction (33%), dyslipidemia (54%), diabetes (33%), current smoking (30%). Main procedures duringthe hospitalization were coronary angiogram (67%), angioplasty (33%; 88% with stent) and coronary bypass surgery (7%). Duringprocedures, 31% of patients received clopidogrel, and 4.2% glycoprotein Ilb/IIIa antagonists. Medical management was selected for 60% of patients. In comparison to men, women received less interventional procedures despite havingmore risk factors. Treatments prescribed at discharge were aspirin (97%), clopidogrel (49%), beta blockers (78%), diuretics (21%), lipid lowering agents (78%), oral hypoglycemic agents (13%) and insulin (9%). At the end ofthe 1-year follow-up, treatments were aspirin (84%), beta blockers (72%), diuretics (19%), and dual antiplatelet therapy with clopidogrel (16%). Conclusions: A high prevalence of múltiple risk factors for cardiovascular disease in Chilean patients with NSTEMI was observed. More aggressive primary and secondary preventive measures are urgently needed. Use of therapies proposed in the guidelines is high, but dual antiplatelet therapy is less than 50% at discharge and decreases during the one year-follow-up.

diabetes mellitus ,coronary stents ,PTCA - Abstract
Antecedentes:Los pacientes diabéticos tratados con angioplastía coronaria (AC) poseen un mayor riesgo de reestenosis y por lo tanto de reintervención en comparación a los no diabéticos, lo que ha derivado en una mayor utilización de stents recubiertos con drogas en este grupo de pacientes. Objetivo: Analizar la incidencia de reintervención en pacientes diabéticos no seleccionados sometidos a una AC con stent no recubierto en el Hospital Regional de Concepción e identificar los predictores de la reintervención. Método: Entre Enero 2005 y Diciembre 2006, 571 pacientes fueron sometidos AC, de los cuales 108 (19%) eran diabéticos. En este grupo estudiamos sus características clínicas, factores de riesgo y los factores angiográficos tales como el vaso tratado, diámetro, longitud y número de stents. Mediante un seguimiento telefónico y de ficha clínica se determinó la existencia o no de una reintervención coronaria. Identificado el grupo con reintervención coronaria, comparamos las variables clínicas y angiográficas y a través de un modelo de regresión logística se buscó identificar predictores de dicha intervención. Se utilizó t de student y test exacto de Fisher. Resultados: La edad promedio fue 61 ±10 años, 71(66%) hombres y 25% insulinorequirientes 47(44%) pacientes tenía dislipidemia, 93(86%) hipertensión y 26(25%) eran fumadores. La AC fue en contexto de un SCA s/SDST en 56(52%) pacientes, 38(35%) por I AM en evolución y 12(11%) por angina estable. Se implantaron 138 stents (1,3 stent/pt) y fue exitosa en el 96%. En el seguimiento de 13,7 ±7 meses la mortalidad fue 4,6% y sólo 12(11%) pacientes fueron sometidos a una nueva revascularización, 75% de las cuales fue otra AC. De las reintervenciones, sólo 4(33%) pacientes tenía reestenosis, el resto fue por lesiones en otro vaso. La distribución de los factores de riesgo clínicos y angiográficos fue similar entre los grupos con y sin reintervención, sin embargo, se observó una tendencia a mayor reintervenciones cuando la arteria tratada fue la descendente anterior (ADA) proximal (67%),cuando el diámetro de referencia del vaso es < 3 mm (67%) y cuando la AC ocurre en el marco de un SCA s/SDST (58%) (p=ns). Conclusión: En nuestra práctica diaria, la reintervención de pacientes diabéticos tratados con stents no recubiertos es baja y se concentra (aunque no significativamente) en lesiones de la ADA proximal, en vasos < 3 mm y en pacientes con SCA. Background: Diabetes mellitus is associated to a more severe and extensive coronary artery disease. Coronary angioplasty (PTCA) has been demonstrated to have similar immediate results compared with patients without diabetes; however, diabetic patients exhibit a higher rate of restenosis and target lesion revascularization. Aim: to study the real incidence of a new interventional procedures in diabetics patients who were treated with bare metal stents. Methods: From January 2005 to December 2006, 571 patients were submitted to PTCA at the Hospital Regional de Concepción. 108 patients (195) were diabetics. Clinical characteristics, risk factors, and angiographic findings were tabulated. Telephone follow up was used to determine the performance of coronary re intervention. A logistics regression model was used to identify predictors of coronary re intervention. Results: The mean average age was 61±10 years, 66% were men and 25% required insulin treatment. Dyslypidemia was present in 86%, hypertension in 86% and 25% were smokers. Indication for PTCA was acute coronary syndrome in 52%, myocardial infarction in 35% and stable angina in 11%. They received 1,3 stents/pts and immediate success rate was 96%. During follow up (13,7±7 months) global mortality was 4,6% and only 12 (11%) patients had a second revascularization procedure, 67% of them performed in non stented coronary arteries. Four revascularizations (33%) were due to significant in-stent restenosis, seven (58%) to other significant lesions and 1 to subacute stent thrombosis. In the univariate and multivanate analysis we did not find independent clinical or angiographic factors as predictors of new revascularization. However, it was more frequent in patients with proximal left anterior descending artery stents and long lesions (58% and 50%, respectively). Conclusion: In our experience, need for repeat revascularization in diabetic patients previously treated with bare metal stents is low, and mainly due to lesions of proximal LAD.

- Abstract
The Chilean Society of Cardiology and Cardiovascular Surgery (SOCHICAR) is a scientific society whose mission is to improve the nation's cardiovascular health. Its primary goals include discussing issues affecting the specialty and engaging in various activities that support its advancement. To achieve these goals, numerous educational initiatives are undertaken for health professionals, including physicians in cardiology training programs. Training specialists in Chile is the responsibility of the universities, which design the curriculum and plan the program according to the graduate profile. SOCHICAR seeks to integrate these new generations of cardiologists, setting up tasks that contribute to their training. It seemed relevant to us to state our position as a Scientific Society in importants aspects related to this process: the graduate profile of the clinical cardiologist, the necessary competencies for their performance nationally, the identification of deficient areas in their training period, and the Society's contributions to this university-dependent process. A total of 15 cardiologists from SOCHICAR, at different stages of professional development, various geographic areas, and areas of performance and functions, were invited to participate in three working groups. This SOCHICAR position statement may be useful and an important source of information to be considered by authorities, accrediting entities, training centers, and the Chilean Society of Cardiology.

- Abstract
Background: The presence of a chronic total occlusion (CTO) in a non-infarct-related artery in patients with acute myocardial infarction (AMI), may be a sign of bad prognosis., Aim: To estimate the long-term survival of patients with AMI who were studied with coronarography during 2013-2014 who had one or more CTO in a non-infarct-related artery., Material and Methods: Review of coronary angiograms performed between 2013 and 2014 to patients with an AMI. Patients were grouped as having or not a CTO in a non-infarct-related artery. Their medical records were reviewed, and mortality was determined requesting their death certificates., Results: Of 993 patients with AMI under-going coronarography, 233 (23.5%) had at least one CTO. Patients with CTO were older (66 and 62 years respectively). They also had a higher prevalence of hypertension, diabetes mellitus (DM), kidney failure and moderate to severe systolic ventricular dysfunction. The independent predictors of mortality were CTO, age, DM and kidney failure. Survival at an average follow-up period of 57 months was significantly higher in patients without CTO (89.5 and 80.3% respectively, p < 0.01)., Conclusions: The presence of CTO in patients with acute myocardial infarction is associated with a higher frequency of cardiovascular risk factors and lower long-term survival.

- Abstract
Atherosclerosis is the main cause of late saphenous vein graft (SVG) failure. Intracoronary images using optical coherence tomography (OCT) in addition to angiography allow a detailed analysis of the lesion beyond the degree of stenosis. We report a 67 years old diabetic male who underwent coronary surgery in 2009, consulting for an acute coronary syndrome. Angiography showed two different lesions on one aortocoronary venous grafts. OCT demonstrates atherosclerosis in different stages identifying the culprit lesion. Stent placement were successfully carried out.

- Abstract
Background: Hydatidosis is an endemic zoonosis in different areas of Chile, including the Region of Coquimbo, this is linked to the slaughter of cattle and presence of dogs., Objective: To identify risk factors related to hydatidosis in the home of high school students of Punitaqui., Material: A descriptive cross-sectional study was done by the application of a self-administered questionnaire to 274 students of high school. The information was analyzed by urban/rural area in five dimensions: knowledge, basic sanitation, keeping dogs, vegetable growing and cattle slaughtering and possession., Results: 84.6% of urban students reported not having received hydatidosis education. In rural areas, 93.5% reported owning dogs, with an average of 2.95 dogs/home (p < 0.001). In urban areas 44.4% of the dogs had not been dewormed and 60.3% (p < 0.001) was fed with viscera in rural areas. The 66.2% of cattle were goats and sheep and 64.5% (p < 0.001) of rural households did slaught. The main way to eliminate viscera was feeding the dogs., Conclusions: Risk factors that favor the presence of the parasite were present in relation to keeping dogs and cattle breeding and slaughter, which occurred mostly in rural areas, but being also present in urban areas.

- Abstract
Background: Guidelines for the management of unstable angina (UA) and non ST elevation myocardial infarction (NSTEMI) have been issued, however, current practices are unknown in Chile., Aim: To evaluate in a prospective cohort of NSTEMI patients the current practices, treatments and risk factors., Material and Methods: One year prospective International non interventional registry, conducted in Chile between January 2005 and November 2006., Results: Two hundred thirty three Chilean NSTEMI patients were enrolled. Mortality was 5.5% at the end of the follow-up. Mean age was 61.6 years, and 30.6% were female. Most of the patients had at least one risk factor (98%): hypertension (84%), previous myocardial infarction (33%), dyslipidemia (54%), diabetes (33%), current smoking (30%). Main procedures during the hospitalization were coronary angiogram (67%), angioplasty (33%; 88% with stent) and coronary bypass surgery (7%). During procedures, 31% of patients received clopidogrel, and 4.2% glycoprotein Ilb/IIIa antagonists. Medical management was selected for 60% of patients. In comparison to men, women received less interventional procedures despite having more risk factors. Treatments prescribed at discharge were aspirin (97%), clopidogrel (49%), beta blockers (78%), diuretics (21%), lipid lowering agents (78%), oral hypoglycemic agents (13%) and insulin (9%). At the end of the 1-year follow-up, treatments were aspirin (84%), beta blockers (72%), diuretics (19%), and dual antiplatelet therapy with clopidogrel (16%)., Conclusions: A high prevalence of multiple risk factors for cardiovascular disease in Chilean patients with NSTEMI was observed. More aggressive primary and secondary preventive measures are urgently needed. Use of therapies proposed in the guidelines is high, but dual antiplatelet therapy is less than 50% at discharge and decreases during the one year-follow-up.

- Abstract
Background: The risk of cardiovascular diseases is two to four times higher in diabetic patients., Aim: To study the severity of coronary disease and survival of patients with diabetes mellitus, compared to matched controls without diabetes., Patients and Methods: A retrospective review of all coronary angiographies performed at a private hospital. All diabetic patients with coronary lesions over 50% were considered as the index group. Non diabetic patients with coronary artery lesions over 50% and with similar demographic features and risk factors to the diabetic patients group, were studied as controls. A follow up was done reviewing clinical records and by telephone interviews. Mortality was obtained reviewing death certificates., Results: Seventy seven diabetic patients (48 male, mean age 61+/-10 years and 129 non diabetic subjets (87 males, mean age 61+/-10 years) were studied. Mean follow up in diabetic and non diabetic patients was 1,270 and 1,340 days respectively. Diabetic patients had a higher frequency of multiple vessel disease than their non diabetic counterparts (69 and 52% respectively, p<0.003). Ejection fraction was 61 and 65% in diabetics and non diabetics. General mortality was 15.5 and 2.3% in diabetics and non diabetic respectively (p<0.01). Cardiovascular mortality was 9.1 and 0.8% in diabetics and non diabetics respectively (p 0.002)., Conclusions: Diabetic patients with coronary artery disease have a lower survival and more extensive coronary artery lesions than non diabetic patients with similar age, sex and overall coronary risk.
