Distribution and prognostic value of high-sensitive troponin T measurement in patients with type 2 diabetes without cardiovascular disease.

AIM: The objective of this work was to define a value for the 99th percentile of high-sensitive troponin T and to evaluate the prognostic value of this biomarker in a population of patients with type 2 diabetes without a history of cardiovascular disease. METHODS: In this prospective, observational and analytic study, 482 patients with type 2 diabetes were enrolled. The patients were asymptomatic, with no history of cardiovascular events, renal insufficiency, or inflammatory or systemic disease. As events we considered a combined end point of major adverse cardiovascular events (MACE). RESULTS: 94.9% of the patients had detectable troponin values, 20.7% of the patients had troponin values above the healthy population reference upper threshold (14pg/mL). The 99th percentile value for this patient population was 48pg/mL. Age, sex, the glomerular filtration rate and hypertension were associated with troponin values>14pg/mL. The incidence of MACE was 3.96 per 100 patients/year (p/y) between those with hs-TnT>14pg/mL and 1.07 per 100 p/y between those with hs-TnT≤14pg/mL (HR=3.78 CI95 1.49-9.58; p=0.005). CONCLUSIONS: The 99th percentile value of troponin T in a population of patients with type 2 diabetes is 3-fold higher than the value proposed by the manufacturer for a healthy population. We also observed a significant difference in the distribution of troponin T values between men and women. This biomarker may be a valuable prognostic factor, since troponin T values above the reference upper threshold were associated with an increase in the risk of cardiovascular events in these patients.

Aplicación sistemática de un algoritmo para el manejo lipídico en pacientes de muy alto riesgo cardiovascular. Impacto en los objetivos lipídicos / Systematic Application of an Algorithm for Lipid Management in Cardiovascular High-Risk Patients. Impact on Lipid Goals

RESUMEN Objetivo: Analizar el tratamiento hipolipemiante indicado y verificar el cumplimiento de las metas lipídicas recomendadas durante la internación y en el seguimiento precoz, luego de aplicar sistemáticamente un algoritmo para el manejo lipídico basado en las recomendaciones actuales. Material y métodos: Se incluyeron en forma consecutiva pacientes internados con síndrome coronario agudo o revascularización programada. Se aplicó sistemáticamente un algoritmo para el manejo lipídico, que incluyó: 1) indicación precoz de estatinas de alta intensidad en la internación; 2) seguimiento precoz (controles a las 6 y 12 semanas). La terapia indicada se basó en los documentos de posición de la Sociedad Argentina de Cardiología. Se analizó el cumplimiento de las metas de C-LDL (<70 mg/dl) a las 6 y 12 semanas. Resultados: Se incluyeron 292 pacientes. Se indicó estatinas (95,9% de alta intensidad) a todos los pacientes al alta hospitalaria. A las 6 semanas, el 62,5% alcanzó la meta de C-LDL. Se modificó el esquema terapéutico en el 36,3% de los sujetos (aumento de la dosis de estatinas: 19,7%; agregado de ezetimibe: 67,7%). A las 12 semanas, el 69,1% del subgrupo que no había alcanzado la meta a las 6 semanas logró el objetivo lipídico. Se indicó un inhibidor de la PCSK9 (iPCSK9) a 7 pacientes. Globalmente, el 88,4% alcanzó la meta de C-LDL a las 12 semanas. Conclusión: La aplicación sistemática de un algoritmo basado en las guías determinó que muchos sujetos de alto riesgo cardiovascular alcanzaran las metas de C-LDL a las 12 semanas. La indicación de un iPCSK9 quedó reservada para un grupo reducido de pacientes.

ABSTRACT Objective: The aim of this study was to analyze the indicated lipid-lowering therapy and verify the achievement of the recommended lipid goals during hospitalization and early follow-up, after the systematic application of a lipid management algorithm based on current recommendations. Methods: Patients hospitalized for acute coronary syndrome or programmed revascularization surgery were prospectively included in the study. A lipid management algorithm, including; 1) early indication of high-intensity statins during hospitalization and 2) early follow-up (6 and 12-week controls), was systematically applied. The therapy indicated was based on position documents of the Argentine Society of Cardiology. Achievement of LDL-C goals (<70 mg/dl) at 6 and 12 weeks was analyzed. Results: A total of 292 patients were prescribed statins (high-intensity in 95.9% of cases) at hospital discharge. AT 6 weeks, 62.5% reached the LDL-C goal. The therapeutic plan was modified in 36.3% of patients (increased dose of statins in 19.7% and addition of ezetimibe in 67.7%). At 12 weeks, 69.1% of the subgroup which has not fulfilled the goal at 6 weeks, attained the lipid target. A PCSK9 inhibitor (PCSK9i) was indicated in 7 patients. Overall, 88.4% of patients achieved the LDL-C goal at 12 weeks. Conclusion: Many cardiovascular high-risk patients reached LDL-C goals at 12 weeks with the systematic application of a guideline-based algorithm. The indication of a PCSK9i was reserved for a reduced group of patients.

Trasplante cardíaco en adultos con cardiopatías congénitas / Heart Transplantation in Adult Patients with Congenital Heart Disease

RESUMEN Introducción: En las últimas décadas los pacientes con cardiopatías congénitas (CC) han presentando nuevos desafíos en el manejo de las complicaciones, tanto de la patología originaria como de las cirugías correctoras que les han permitido llegar a la adultez. Objetivo: Comunicar los resultados y la evolución de los pacientes con CC que hayan sido evaluados para trasplante en un centro de alta complejidad. Se utilizó la base de datos institucional, y se analizaron los datos de 11 pacientes evaluados para trasplante con diversas patologías congénitas. Accedieron al trasplante 5 de ellos con una sobrevida a 1,6 años del 80%. Los pacientes que se hallaban en lista y no se trasplantaron tuvieron una mortalidad del 66%, y los descartados por comorbilidades presentaron una mortalidad del 35%. Conclusión: El trasplante cardíaco en adultos con CC tiene un riesgo periprocedimiento más elevado que para las cardiopatías adquiridas (CA). No obstante, los que sobreviven el primer año postrasplante tienen una excelente evolución a largo plazo.

ABSTRACT Background: Over recent decades, congenital heart disease (CHD) patients have posed new challenges in the management of complications, both of the original condition as of the corrective surgeries that have allowed them to reach adulthood. Objective: The aim of this study was to report the outcomes and evolution of CHD patients who had been evaluated for transplantation in a tertiary care center. Using the institutional database, data from 11 patients with different congenital diseases were evaluated for transplantation. A total of 5 patients underwent transplantation, with a 1.6-year survival rate of 80%. Mortality rate was 66% for patients who were on the waiting list but were not transplanted, and 35% for those who were ruled out due to comorbidities. Conclusion: Heart transplantation in CHD adult patients present a higher periprocedural risk than in patients with acquired heart diseases. However, those who survive the first post-transplant year have an excellent long-term outcome.

Características clínicas y evolutivas del síndrome de Takotsubo en un hospital universitario / Clinical Features and Outcomes of Takotsubo Syndrome at a University Hospital

RESUMEN: Introducción: El síndrome de Takotsubo (ST) es una miocardiopatía reversible que tiene diversas formas de presentación. Hasta el momento no se han publicado datos de ST en nuestro medio. Material y Métodos: Desde el 2005 al 2017 se incluyeron a 115 pacientes con diagnóstico de ST primario o secundario en el Hospital Italiano de Buenos Aires. El objetivo fue evaluar las características clínicas del ST durante la internación. Resultados: La mediana de edad de la población fue de 78 años (64-84), el 90% eran mujeres, y el 22% presentó enfermedad coronaria asociada. El 57% eran ST primarios, 31% tuvieron un gatillo emocional y 44%, físico. El síndrome de presentación fue como shock: 9%, insuficiencia cardiaca 12%, "tipo SCA" 70%, ACV/embolia 5% y, arritmias, 4%. La mediana de Fey al ingreso fue del 40% (36-50) y su recuperación, desde el ingreso al alta (mediana de internación de 4 días, 3-8), fue del 20%, p < 0.001. La mortalidad hospitalaria fue de 4/115 (3,48%). En el análisis univariado, las variables asociadas a mayor mortalidad fueron: shock respecto a otras formas de presentación (p = 0.0035) y ST secundario respecto al primario, p = 0.020. Además, existió una relación directa entre la mortalidad y los niveles de NT-pro-BNP máximo (p = 0.0082) y glóbulos blancos (p = 0.0101). Asimismo, la mortalidad hospitalaria mostró una relación inversa con el hematocrito (p = 0.0084) y con las alteraciones en el ECG de ingreso; es decir, que los pacientes que fallecieron durante la internación tuvieron ECG normal al ingreso con mayor frecuencia (p < 0.001). Conclusión: En este registro unicéntrico se observó que los pacientes tuvieron más comorbilidades y similar mortalidad respecto a registros internacionales.

ABSTRACT: Background: Takotsubo syndrome (TS) is a reversible cardiomyopathy with many different forms of presentations. There is no local data of TS published so far. Methods: One hundred and fifteen patients with either primary or secondary TS were retrospectively studied at Hospital Italiano de Buenos Aires from 2005 to 2017. The purpose of the study was to assess the clinical features of this population during hospitalization. Results: Median of age was 78 years (64-84); 90% of patients were female, and 22% had associated coronary artery disease. Fifty-seven percent of cases were primary TS, 31% experienced an emotional trigger and 44% had a physical origin. The presentation syndrome was as follows: 9% shock, 12% heart failure, 70 % mimicking acute coronary syndrome, 5% stroke/peripheral embolism and 4% arrhythmias. Median ejection fraction at admission was 40% (36-50) and recovery from admission to discharge [median hospital stay: 4 days (3-8)] was 20%, p <0.001. In-hospital mortality was 4/115 cases (3.48%). In univariate analysis, shock compared with other forms of presentation (p=0.0035) and secondary TS (p=0.020) were associated with higher in-hospital mortality. There was a direct relationship between in-hospital mortality and maximum NT-pro-BNP levels (p= 0.0082) and white cell count (p=0.0101). In addition, in-hospital mortality was inversely associated with hematocrit (p=0.0084) and with ECG abnormalities at admission; i.e. patients who died during hospitalization had more frequently normal ECG at admission, (p<0.001). Conclusion: Compared with international registries, this single center population had more comorbidities, but similar in-hospital mortality rates.

Mortalidad en pacientes con psoriasis. Análisis de una cohorte retrospectiva / Mortality in patients with psoriasis. A retrospective cohort study

Fundamentos y objetivos: Las modificaciones inmunológicas e inflamatorias observadas en la psoriasis podrían favorecer el desarrollo de la aterosclerosis, aumentando consecuentemente la mortalidad. Los objetivos fueron: 1) determinar la mortalidad de una población con psoriasis en comparación con un grupo control, y 2) conocer la prevalencia de los factores de riesgo cardiovascular. Pacientes y método: Se analizó una cohorte retrospectiva a partir de una base de datos secundaria (historia clínica electrónica). Se incluyeron todos los pacientes con diagnóstico de psoriasis a 1-01-2010, comparándolos con un grupo control del mismo sistema de salud, seleccionados de forma aleatoria (relación 1:1). Se excluyeron los sujetos con antecedentes cardiovasculares. Se realizó un análisis de sobrevida, determinando como episodio la muerte por cualquier causa. El seguimiento se extendió hasta el 30-6-2015. Resultados: Se analizaron 1.481 pacientes con psoriasis y 1.500 controles. La prevalencia de los factores de riesgo cardiovascular fue más elevada en el grupo con psoriasis. El tiempo promedio de seguimiento fue de 4,6±1,7 años. La mortalidad fue mayor en los psoriásicos en comparación con los controles (15,1 frente a 9,6 episodios cada 1.000 personas-año, p < 0,005). La psoriasis se asoció significativamente con una mayor mortalidad en comparación con el grupo control en el análisis univariado (HR 1,58, IC 95% 1,16-2,15, p = 0,004) y luego de ajustar por los factores de riesgo cardiovascular (HR 1,48, IC 95% 1,08-2,3, p = 0,014). Conclusión: En esta población, los pacientes con psoriasis mostraron una mayor prevalencia de factores de riesgo cardiovascular en el momento del diagnóstico y una mayor mortalidad en el seguimiento (AU)

Background and objectives: The immune and inflammatory pathways involved in psoriasis could favor the development of atherosclerosis, consequently increasing mortality. The objectives of this study were: 1) to assess the mortality of a population with psoriasis compared to a control group, and 2) to assess the prevalence of cardiovascular risk factors. Patients and method: A retrospective cohort was analyzed from a secondary database (electronic medical record). All patients with a diagnosis of psoriasis at 1-01-2010 were included in the study and compared to a control group of the same health system, selected randomly (1:1). Subjects with a history of cardiovascular disease were excluded from the study. A survival analysis was performed considering death from any cause as an event. Follow-up was extended until 30-06-2015. Results: We included 1,481 subjects with psoriasis and 1,500 controls. Prevalence of cardiovascular risk factors was higher in the group with psoriasis. The average follow-up time was 4.6±1.7 years. Mortality was higher in psoriasis patients compared to controls (15.1 vs. 9.6 events per 1,000 person-year, P < .005). Psoriasis was seen to be significantly associated with increased mortality rates compared to the control group in the univariate analysis (HR 1.58, 95% CI 1.16-2.15, P = .004) and after adjusting for cardiovascular risk factors (HR 1.48, 95% CI 1.08-2.3, P = .014). Conclusion: In this population, patients with psoriasis showed a higher prevalence for the onset of cardiovascular risk factors as well as higher mortality rates during follow-up (AU)

Metas de colesterol LDL en pacientes sometidos a revascularización periférica / LDL Cholesterol Targets in Patients Undergoing Peripheral Revascularization

Introducción: Los pacientes con enfermedad vascular periférica representan un grupo de riesgo alto de eventos cardiovasculares, por lo que deben alcanzar las metas de prevención secundaria recomendadas en las guías. Objetivos: Primario: Determinar qué porcentaje de pacientes sometidos a cirugía de revascularización periférica alcanzan las metas de colesterol LDL a los 6 meses de la intervención en comparación con los pacientes sometidos a cirugía de revascularización coronaria. Secundarios: Determinar el mencionado porcentaje a los 18 meses de seguimiento. Determinar el porcentaje de dosaje de colesterol total y fracciones de lípidos (C-LDL, C-HDL y TG) a los 6 y 18 meses de seguimiento. Determinar el porcentaje de uso de estatinas durante el año previo y durante el período de seguimiento alejado de la cirugía. Material y métodos: Se comparó el grado de control de lípidos de una cohorte retrospectiva de pacientes sometidos a cirugía de revascularización periférica con otra de pacientes sometidos a cirugía de revascularización coronaria luego de 6 meses y 18 meses del procedimiento. Resultados: Se siguieron 468 individuos, 98 operados por enfermedad vascular periférica y 370 por enfermedad coronaria por un período de 18 meses. La media de LDL a los 6 meses de la cirugía fue significativamente mayor en los vasculares que en los coronarios (98,8 ± 35 mg/dl vs. 84,7 ± 25 mg/dl; p = 0,001). Esta diferencia perdió significación a los 18 meses (93,3 ± 23 mg/dl vs. 88 ± 26 mg/dl; p = 0,25). El porcentaje de alcance de la meta de LDL < 100 mg/dl a los 6 meses en los vasculares y coronarios fue 27,5% vs. 48,6% (p < 0,0001) y a los 18 meses fue 22,5% vs. 37,3% (p = 0,006). Conclusión: Los pacientes sometidos a procedimientos quirúrgicos de revascularización periférica alcanzan las metas de C-LDL en un porcentaje menor en comparación con los sometidos a revascularización coronaria.

Background: Patients with peripheral vascular disease represent a group at high risk of cardiovascular events, and must therefore achieve the secondary prevention goals recommended in the guidelines. Objectives: Primary: To determine what percentage of patients undergoing peripheral revascularization surgery reached LDL cholesterol goals at 6 months of the intervention compared with patients undergoing coronary artery bypass grafting. Secondary: To determine the percentage of patients reaching these levels at 18 months of follow-up, the percentage of patients with total cholesterol dosage and lipid fraction (LDL-C, HDL-C and TG) assessment at 6 and 18 months of follow-up and the percentage of statin use during the previous year and during the long term follow-up after surgery. Methods: The degree of lipid control in a retrospective cohort of patients undergoing peripheral revascularization surgery was compared with another group of patients undergoing coronary artery bypass grafting at 6 months and 18 months of the procedure. Results: A total of 468 individuals, 98 undergoing surgery for peripheral vascular disease and 370 for coronary artery disease were followed up for a period of 18 months. Mean LDL-C at 6 months of surgery was significantly higher in the vascular than in the coronary patients (98.8±35 mg/dl vs. 84.7±25 mg/dl, p=0.001), but lost significance at 18 months (93.3±23 mg/dl vs. 88±26 mg/dl, p=0.25). The percentage of patients achieving LDL-C target <100 mg/dl was 27.5% vs. 48.6% (p <0.0001) at 6 months in the vascular and coronary patients, respectively, and 22.5% vs. 37.3% (p=0.006) at 18 months. Conclusion: A lower percentage of patients undergoing surgical procedures for peripheral revascularization achieve LDL-C targets compared with those undergoing coronary revascularization.

Comportamiento plasmático y clínico del ácido láctico en el trasplante cardíaco / Plasmatic pattern and clinical outcomes of lactic acid in heart transplantation

Resumen Introducción Hay controversia en relación con el ácido láctico luego del trasplante cardíaco. Objetivo Evaluar el patrón plasmático del ácido láctico y su valor pronóstico luego del trasplante cardíaco. Métodos Entre el 2011 y el 2014 se incluyeron 127 pacientes luego de cirugía cardíaca, 71 pertenecieron al grupo trasplante y 56 al grupo "control", conformado por pacientes sometidos a cirugía de revascularización miocárdica. Se compararon los niveles de ácido láctico antes de la cirugía, al ingreso en la Unidad Coronaria, y a las 6, 12 y 24 h en los 2 grupos. Dentro del grupo trasplante se realizó un análisis uni y bivariado entre niveles de ácido láctico y mortalidad hospitalaria. Resultados La media de edad fue de 57 años. Los niveles de ácido láctico fueron significativamente mayores durante y luego de la cirugía cardíaca en los pacientes del grupo trasplante respecto a los pacientes del grupo control (p<0.001), pero no existieron diferencias significativas en los valores antes de la cirugía (p=0.143; comparaciones no ajustadas). En los trasplantados, los niveles de ácido láctico se asociaron de forma significativa a una mayor mortalidad durante la cirugía, al ingreso, y a las 6, 12 y 24 h. El ácido láctico al ingreso fue un predictor de muerte ajustado por volumen minuto postoperatorio (p=0.011), uso de ≥ 2 inotrópicos (p=0.033), glucemia al ingreso (p=0.004), edad ≥ 60 años (p=0.015), tiempo de bomba (p=0.027) y pH (p=0.017). Conclusiones Los niveles de ácido láctico fueron mayores en los trasplantados y se asociaron a una mayor mortalidad hospitalaria.

Abstract Introduction It is not well established the prognostic value of elevated lactic acid after heart transplantation. Objective To evaluate the plasmatic pattern and the prognostic value of elevated lactate after heart transplantation. Methods One-hundred and twenty seven patients were included between 2011 and 2014, 71 comprising the transplantation group and 56 the control group, represented by on pump coronary artery by-pass surgery patients. Lactic acid levels were compared between groups before, within and after surgery upon Coronary Care Unit admission, at 6, 12 and 24 h. In addition, in the transplantation group univariate and bivariate analysis were performed between lactic acid levels and in-hospital mortality. Results The mean age of the entire cohort was 57 years. Among transplanted patients, lactic acid levels were significantly higher over control group: within the surgery; and after surgery (P<.001), but not before surgery (P=.143; unadjusted comparisons). In transplanted patients, lactic acid levels were significantly associated with in-hospital mortality during surgery, at admission, and thereafter but not before surgery. Lactic acid at admission was associated with in-hospital mortality after adjustment of postoperative cardiac output (P=.011), ≥ 2 inotropic drug support within 24 h (P=.033), glycemic level at admission (P=.004), age ≥ 60 years (P=.015), on pump time (P=.027), and pH (P=.017). Conclusions Acid lactic levels were higher in transplanted patients than in the control group and was associated to higher in-hospital mortality.

Low rate of cardiovascular events in patients with acute myocarditis diagnosed by cardiovascular magnetic resonance.

BACKGROUND: Myocarditis is a relatively common inflammatory disease that affects the myocardium. Infectious disease accounts for most of the cases either because of a direct viral infection or post-viral immune-mediated reaction. Cardiovascular magnetic resonance (CMR) has become an established non-invasive diagnosis tool for acute myocarditis. A recent large single centre study with patients with biopsy-proven viral myocarditis undergoing CMR scans found a high rate of mortality. The aim of this study was to assess the rate of clinical events in our population of patients with diagnosed myocarditis by CMR scan. METHODS: Patients who consulted to the emergency department with diagnosis of myocarditis by CMR were retrospectively included in the study from January 2008 to May 2012. A CMR protocol was used in all patients, and were followed up to assess the rate of the composite endpoint of all-cause death, congestive heart failure, sudden cardiac death, hospitalization for cardiac cause, recurrent myocarditis or need of radiofrequency ablation or implantable cardiac defibrillator (ICD). A descriptive statistical analysis was performed. RESULTS: Thirty-two patients with myocarditis were included in the study. The mean age was 42.6±21.2 years and 81.2% were male. In a mean follow up of 30.4±17.8 months, the rate of the composite endpoint of all-cause death, congestive heart failure, sudden cardiac death, hospitalization for cardiac cause, recurrent myocarditis or need of radiofrequency ablation or ICD was 15.6% (n=5). Two patients had heart failure (one of them underwent heart transplant), one patient needed ICD because of ventricular tachycardia and two other patients were re-hospitalized, for recurrent chest pain and for recurrent myocarditis respectively. CONCLUSIONS: In our series of acute myocarditis diagnosed by CMR we found a low rate of cardiovascular events without mortality. These findings might oppose data from recently published myocarditis trials.

[Coronary artery disease in patients with psoriasis]. / Enfermedad coronaria en pacientes con psoriasis.

In previous reports, psoriasis was associated with an increased rate of coronary artery disease. These data has not been investigated in our population. We performed a cross-sectional study analyzing data from electronic medical records of a health system in Buenos Aires. We included all patients older than 18 years diagnosed with psoriasis between January 1, 2003 and July 31, 2011 and compared them with a control group. Controls were selected randomly by strata of age and sex from the same health system in a 2:1 ratio. We determined the prevalence of cardiovascular risk factors and coronary heart disease. We analyzed the association between psoriasis and coronary artery disease by both univariate and multivariate analyzes. In total, 3 833 subjects were included (1 286 with psoriasis and 2 547 controls). The prevalence of hypertension (50% vs. 38%, p < 0.001), smoking (25% vs. 17%, p < 0.001), diabetes (12% vs. 8%, p < 0.001) and coronary artery disease (4.98% vs. 3.06%, p = 0.003) were higher in the psoriasis group compared to controls. Regardless age and the presence or absence of diabetes, hypertension or smoking, there was a significant association between coronary artery disease and psoriasis (OR 1.48, CI95% 1.04-2.11, p = 0.03). In conclusion, in this population of Buenos Aires, psoriasis patients had a higher prevalence of diabetes, hypertension, smoking, and coronary artery disease. The association between psoriasis and coronary artery disease was independent of the risk factors explored.

Enfermedad coronaria en pacientes con psoriasis / Coronary artery disease in patients with psoriasis

Comunicaciones previas asociaron la psoriasis con la enfermedad coronaria. Desconocemos si en nuestro país o región existe dicha asociación. Se realizó un estudio transversal analizando los datos de la historia clínica electrónica de un sistema de salud de Buenos Aires. Analizamos todos los pacientes mayores de 18 años con diagnóstico de psoriasis entre el 1 de enero de 2003 y el 31 de julio de 2011 y los comparamos con un grupo control, en una relación 2:1, obtenido en forma aleatoria del mismo sistema de salud, apareados por edad y sexo. Determinamos la prevalencia de los factores de riesgo cardiovascular y de enfermedad coronaria. Analizamos la asociación entre la enfermedad coronaria y la psoriasis mediante análisis uni y multivariado. Se incluyeron 3 833 sujetos (1 286 pacientes con psoriasis y 2 547 controles). La prevalencia de hipertensión arterial (50% vs. 38%, p < 0.001), tabaquismo (25% vs. 17%, p < 0.001), diabetes (12% vs. 8%, p < 0.001) y enfermedad coronaria (4.98% vs. 3.06%, p = 0.003) fue mayor en los sujetos con psoriasis en comparación con el grupo control. Independientemente de la edad, la presencia de diabetes, hipertensión arterial o tabaquismo, hubo una asociación significativa entre la enfermedad coronaria y la psoriasis (OR 1.48, IC95% 1.04-2.11, p = 0.03). En conclusión, en esta población de Buenos Aires, los pacientes con psoriasis tuvieron una mayor prevalencia de diabetes, hipertensión arterial, tabaquismo y enfermedad coronaria. La asociación entre la psoriasis y la enfermedad coronaria fue independiente de los factores de riesgo explorados.(AU)

Controls were selected randomly by strata of age and sex from the same health system in a 2:1 ratio. We determined the prevalence of cardiovascular risk factors and coronary heart disease. We analyzed the association between psoriasis and coronary artery disease by both univariate and multivariate analyzes. In total, 3 833 subjects were included (1 286 with psoriasis and 2 547 controls). The prevalence of hypertension (50% vs. 38%, p < 0.001), smoking (25% vs. 17%, p < 0.001), diabetes (12% vs. 8%, p < 0.001) and coronary artery disease (4.98% vs. 3.06%, p = 0.003) were higher in the psoriasis group compared to controls. Regardless age and the presence or absence of diabetes, hypertension or smoking, there was a significant association between coronary artery disease and psoriasis (OR 1.48, CI95% 1.04-2.11, p = 0.03). In conclusion, in this population of Buenos Aires, psoriasis patients had a higher prevalence of diabetes, hypertension, smoking, and coronary artery disease. The association between psoriasis and coronary artery disease was independent of the risk factors explored.(AU)

Enfermedad coronaria en pacientes con psoriasis / Coronary artery disease in patients with psoriasis

Comunicaciones previas asociaron la psoriasis con la enfermedad coronaria. Desconocemos si en nuestro país o región existe dicha asociación. Se realizó un estudio transversal analizando los datos de la historia clínica electrónica de un sistema de salud de Buenos Aires. Analizamos todos los pacientes mayores de 18 años con diagnóstico de psoriasis entre el 1 de enero de 2003 y el 31 de julio de 2011 y los comparamos con un grupo control, en una relación 2:1, obtenido en forma aleatoria del mismo sistema de salud, apareados por edad y sexo. Determinamos la prevalencia de los factores de riesgo cardiovascular y de enfermedad coronaria. Analizamos la asociación entre la enfermedad coronaria y la psoriasis mediante análisis uni y multivariado. Se incluyeron 3 833 sujetos (1 286 pacientes con psoriasis y 2 547 controles). La prevalencia de hipertensión arterial (50% vs. 38%, p < 0.001), tabaquismo (25% vs. 17%, p < 0.001), diabetes (12% vs. 8%, p < 0.001) y enfermedad coronaria (4.98% vs. 3.06%, p = 0.003) fue mayor en los sujetos con psoriasis en comparación con el grupo control. Independientemente de la edad, la presencia de diabetes, hipertensión arterial o tabaquismo, hubo una asociación significativa entre la enfermedad coronaria y la psoriasis (OR 1.48, IC95% 1.04-2.11, p = 0.03). En conclusión, en esta población de Buenos Aires, los pacientes con psoriasis tuvieron una mayor prevalencia de diabetes, hipertensión arterial, tabaquismo y enfermedad coronaria. La asociación entre la psoriasis y la enfermedad coronaria fue independiente de los factores de riesgo explorados.

Prognostic value of left atrial volume in asymptomatic organic mitral regurgitation.

BACKGROUND: Basal left atrial volume (LAV) indexed to body surface area (LAVI) predicts adverse events in patients with organic mitral regurgitation, but information is lacking regarding change in left atrial volume during follow-up. METHODS: One hundred forty-four asymptomatic patients (mean age, 71 ± 12 years; 66% women; mean ejection fraction, 66 ± 4.8%) with moderate to severe mitral regurgitation were prospectively included, with a median follow-up period of 2.76 years (interquartile range, 1.86-3.48 years). RESULTS: Fifty-four patients (37.50%) reached the combined end point of dyspnea and/or systolic dysfunction. Both basal and change in LAV were independently associated with the combined end point on multivariate analysis: for basal LAVI ≥ 55 mL/m(2), odds ratio, 2.26 (95% confidence interval, 1.04-4.88; P = .038), and for change in LAV ≥ 14 mL, odds ratio, 7.32 (95% confidence interval, 3.25-16.48; P < .001), adjusted for effective regurgitant orifice area and deceleration time. Combined event-free survival at 1, 2, and 3 years was significantly less in patients with basal LAVI ≥ 55 mL/m(2) (75%, 58%, and 43%) than in those with basal LAVI < 55 mL/m(2) (95%, 89%, and 77%) (log-rank test = 15.38, P = .0001). The incidence of the combined end point was highest (88%) in patients with basal LAVI ≥ 55 mL/m(2) and change in LAV ≥ 14 mL. CONCLUSIONS: Measurement of basal LAV and its increase during follow-up predict an adverse course in patients with moderate and severe asymptomatic mitral regurgitation. Hence, its assessment could be incorporated into the currently used algorithm for risk stratification and decision making in this group of patients.

Precisión diagnóstica del espesor íntima-media carotídeo para la detección de aterosclerosis coronaria: utilidad en la práctica clínica / Diagnostic Accuracy of Carotid Intima-Media Thickness to Detect Coronary Atherosclerosis: usefulness in Clinical Practice

Introducción El espesor íntima-media carotídeo (EIMC) es un marcador independiente de riesgo cardiovascular. El puntaje de calcio coronario (PCC) es un predictor superior al EIMC, pero de costo elevado y en nuestro país pocos pacientes pueden acceder a su medición. Objetivos 1) Evaluar la precisión diagnóstica del EIMC para la detección de un PCC > 0. 2) Determinar el punto de corte óptimo del EIMC para discriminar entre la presencia o la ausencia de calcio coronario. Material y métodos Estudio descriptivo transversal de muestras consecutivas obtenidas en los consultorios de prevención cardiovascular. Se midió el EIMC medio y máximo mediante un eco-Doppler ca-rotídeo. Se efectuó una tomografía computarizada de 64 pistas para la evaluación del PCC. Se determinó la precisión diagnóstica del EIMC para la detección de un PCC > 0 mediante un análisis ROC. Resultados Se incluyeron 202 sujetos consecutivos que participan de un programa de prevención primaria. Características de la población (media ± desviación estándar): edad 57 ± 13 años, sexo femenino: 49%, tabaquismo: 13%, estatinas: 37%, diabetes mellitus: 13%, puntaje de Framingham en no diabéticos: 9% ± 7%, EIMC medio: 0,953 ± 0,342 mm, EIMC máximo: 1,383 ± 0,679 mm, prevalencia de placa aterosclerótica carotídea: 37% y de PCC > 0: 62%. Las correlaciones entre el EIMC medio y máximo y el PCC fueron moderadas (r = 0,56 y r = 0,55, respectivamente). El área bajo la curva ROC del EIMC máximo fue de 0,822 (IC 95% 0,763-0,880) y la del EIMC medio fue de 0,829 (IC 95% 0,771-0,888). El punto de corte óptimo del EIMC máximo para discriminar entre PCC > 0 o PCC = 0 fue de = 1,01 mm y la sensibilidad, la especificidad, el valor predictivo positivo (VPP) y el valor predictivo negativo (VPN) fueron del 78%, 75%, 83% y 67%, respectivamente. El punto de corte óptimo del EIMC medio para discriminar entre PCC > 0 o PCC = 0 fue = 0,82 mm y la sensibilidad, la especificidad, el VPP y el VPN fueron del 77%, 78%, 85% y 67%, respectivamente. Conclusiones En esta población predominantemente de riesgo bajo, la precisión diagnóstica del EIMC para detectar PCC > 0 fue moderada. Una ecografía Doppler carotídea "normal" no excluyó la presencia de aterosclerosis subclínica coronaria. Estos resultados podrían mejorar la selección de pacientes que requieran la medición del PCC para estratificar el riesgo cardiovascular.(AU)

Background Carotid intima-media thickness (CIMT) is an independent marker of cardiovascular risk. Coronary artery calcium score (CACS) is better than CIMT to predict coronary artery disease; yet, few patients have access to this evaluation in our country due to its high cost. Objectives The aim of this study was: 1) to evaluate the diagnostic accuracy of CIMT to detect CACS >0. 2) To determine an optimal cut-off point of CIMT to discriminate between the presence and the absence of coronary artery calcium. Methods We conducted a cross-sectional descriptive study of consecutive samples obtained in the outpatient clinic of cardiovascular prevention. Mean and maximum CIMT were measured using carotid Doppler ultrasound. Carotid artery atherosclerotic plaque (CAP) was evaluated with a 64-row multidetector computed tomography. The diagnostic accuracy of CIMT to detect CACS >0 was determined by ROC analysis. Results A total of 202 consecutive subjects participating in a primary prevention program were included. Population characteristics were (mean ± standard deviation): age 57±13 years, female gender: 49%, smokers: 13%, statins: 37%, diabetes mellitus: 13%, Framingham risk score in non diabetics: 9%±7%, mean CIMT: 0.953±0.342 mm, maximum CIMT: 1.383±0.679 mm, prevalence of carotid artery atherosclerotic plaque: 37% and of CACS >0: 62%. The correlations between mean and maximum CIMT and CACS were poor (r=0.393 and r=0.376, respectively). The area under the ROC curve of maximum CIMT was 0.822 (95% CI 0.763-0.880) and that of mean CIMT was 0.829 (95% CI 0.771-0.888). The optimal cut-off point of maximum CIMT to discriminate between CACS >0 or CACS = 0 was =1.01 mm and sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 78%, 75%, 83% y 67%, respectively. The optimal cut-off point of mean CIMT to discriminate between CACS >0 or CACS = 0 was =0.82 mm and sensitivity, specificity, PPV and NPV were 77%, 78%, 85% and 67%, respectively. Conclusions In this low-risk population, the diagnostic accuracy of CIMT to detect CACS >0 was moderate. A "normal" carotid Doppler ultrasound did not exclude the presence of subcli-nical coronary artery atherosclerosis. These results might improve selection of patients undergoing CACS to stratify cardiovascular risk.(AU)

Estimación de la «edad vascular» basada en el índice de masa corporal en una población en prevención primaria. Asociación con la aterosclerosis carotídea subclínica / Estimation of the ‘‘vascular age’’ based on body mass index in a population in primary prevention. Association with subclinical carotid atherosclerosis

Fundamentos y objetivos: Conocer la relación entre la «edad vascular» (EV) y el diagnóstico de aterosclerosis subclínica podría optimizar la estratificación de riesgo cardiovascular. Los objetivos de este estudio fueron: 1) conocer la EV en una población en prevención primaria, y 2) determinar la relación entre la EV y la presencia de placa aterosclerótica carotídea (PAC). Pacientes y método: Se calculó la EV basada en el índice de masa corporal (IMC), así como la diferencia entre la EV y la edad cronológica (Delta). Se investigó la presencia de PAC por ultrasonido y se analizó la asociación entre quintiles de EV y de Delta con la presencia de PAC. Se realizó un análisis ROC. Resultados: Se incluyeron 411 pacientes, con una edad media (DE) de 47 (10) años; un 54% eran varones. La EV y Delta medias fueron 55 (15) y 7 (9) años, respectivamente. El 75% de los pacientes presentó una EV mayor que la edad cronológica (50% 6 años). Los sujetos con PAC mostraron una EV significativamente mayor (media de 66 [11] frente a 50 [14] años, p < 0,0001) y un mayor Delta (media de 13 [9] frente a 5 [7] años, p < 0,0001) que los sujetos sin PAC. Se observó una asociación positiva entre quintiles de EV y Delta con la prevalencia de PAC. El área bajo la curva y el punto de corte óptimo de la EV para la detección de PAC fueron 0,813 y 60 años, respectivamente, y para Delta, 0,771 y 11 años, respectivamente. Conclusiones: La EV basada en el IMC podría constituir una sencilla herramienta para estimar la presencia de PAC y mejorar la estratificación del riesgo cardiovascular en sujetos en prevención primaria (AU)

Background and objectives: To know the relationship between ‘‘vascular age’’ (VA) and the diagnosis of subclinical atherosclerosis could improve cardiovascular risk stratification. Objectives: 1) to know the VA in a primary prevention population, and 2) to determine the relationship between VA and the presence of carotid atherosclerotic plaque (CAP). Patients and methods: We calculated VA based on body mass index (BMI). We obtained the difference between VA and chronological age (Delta). The screening of CAP was done by ultrasound. We analyzed the association between quintiles of VA and Delta with the presence of CAP. ROC analysis was performed. Results: In total, 411 patients were included (age 47 [10] years, 54% men). The VA and Delta were 55 (15) and 7 (9) years respectively. In 75% of the patients VA was higher than the chronological age (50% 6 years). Subjects with CAP had significantly higher VA (66 [11] versus 50 [14] years, P < .0001) and Delta (13 [9] versus 5 [7] years, P < .0001) than subjects without CAP. We observed a positive association of quintiles of VA and Delta with the prevalence of CAP. The area under de curve and the optimal cutoff point of VA for the detection of CAP were 0.813 and 60 years, respectively, and for Delta, 0,771 and 11 years, respectively. Conclusions: The VA based on BMI could be a simple tool to estimate the presence of CAP and improve cardiovascular risk stratification in patients in primary prevention (AU)

Endocrine and inflammatory profiles in type 2 diabetic patients with and without major depressive disorder.

BACKGROUND: There is a high prevalence of depression in individuals with type 2 diabetes mellitus. Depressive disorders are associated with increased medical morbidity and mortality in individuals with diabetes. It has been demonstrated that there is a higher prevalence of diabetic complications among individuals with diabetes and depression compared to those without depression. Several biological alterations have been reported in individuals with depressive disorders, particularly abnormal levels of endocrine-inflammatory markers.This study aims to determine the prevalence of major depressive disorder (MDD) in type 2 diabetes patients, the prevalence of cardiovascular events in individuals with and without MDD and to compare the endocrine-inflammatory profile between groups. METHODS: The study was approved by the "Comité de Etica de Protocolos de Investigación del Departamento de Docencia e Investigación del Hospital Italiano de Buenos Aires" with the number "1262" and included only patients who provided written informed consent. The study was conducted in accordance with the Declaration of Helsinki and the Habeas Data law on protection of personal data (Law Nª 25326, Argentina).Type 2 diabetes patients (n = 61) were included and they were classified as having MDD or not according to DSM-IV. Macrovascular disease was obtained from the medical history. Additionally, the intima-media thickness of the common carotid, carotid bifurcations and internal carotid arteries was measured non-invasively by two-dimensional ultrasound imaging. Fasting glucose, fasting lipid profile, inflammatory (CRP, TNF-α) and endocrine (urine free cortisol and saliva cortisol) markers. Student t tests were used to compare means for normally distributed variables and Mann-Whitney test for variables without normal distribution. Relative frequencies were calculated and a chi-square analysis was conducted. Data were expressed as mean ± standard deviation (SD) or median and interquartile range. Multivariable logistic regression was used to determine the relative odds of clinical cardiovascular disease in individuals with compared to those without depression. Differences were considered significant using a two-sided p < 0.05. RESULTS: 21 patients (34%) had MDD and 40 patients (66%) didn't have MDD. Diabetic patients with MDD had significantly higher CRP levels (4.1(1.9-7.6) vs 1.5(0.5-4.4) mg/l; p = 0.02) and 24-hour urine free cortisol (71.4 ± 21.3 vs 59.8 ± 29.3 ug/24 h; p = 0.03). The other metabolic and inflammatory parameters were not statistically different between groups. There was a significantly higher prevalence of cardiovascular events in individuals with MDD: 38% for the depressive group vs 15% for non-depressive group, p = 0.04). Patients with MDD had a 3.5-fold greater odd of having cardiovascular disease. CONCLUSIONS: Diabetic patients with depression are more likely to have cardiovascular events, and different factors can determine this high association.

Subjects with CAP had significantly higher VA (66 [11] versus 50 [14] years, P<.0001) and Delta (13 [9] versus 5 [7] years, P<.0001) than subjects without CAP. We observed a positive association of quintiles of VA and Delta with the prevalence of CAP.
