RESUMEN

RESUMEN INTRODUCCIÓN En Argentina, la obesidad en adultos es una problemática con una prevalencia media de 25,4%. En la relación entre COVID-19 y obesidad, se observa mayor prevalencia de sobrepeso/obesidad y enfermedad severa entre los pacientes con COVID-19. Por ello, el objetivo del estudio fue conocer las características clínicas y epidemiológicas en pacientes con diagnóstico de obesidad sobrevivientes a la infección por SARS-CoV-2. MÉTODOS Se realizó un estudio observacional descriptivo y analítico de corte transversal. Se aplicó una encuesta autoadministrada. RESULTADOS La mediana de edad fue 41 años, y hubo un 69,9% de mujeres. Los síntomas de presentación más prevalentes fueron astenia (86,7%), anosmia (64,5%) y tos (64%). Con respecto a los síntomas persistentes luego de las 12 semanas del diagnóstico, los más prevalentes fueron astenia (52,9%), trastornos de sueño (32,4%) y falta de concentración/memoria (31,7%). Hubo mayor riesgo en mujeres (OR: 2,86; IC95%: 2,23-3,67) con obesidad (OR: 1,58; IC95%: 1,16-2,16). La enfermedad grave en obesos fue casi el triple comparado con no obesos (15,7% vs. 5,4%; p<0,001). DISCUSIÓN Los pacientes obesos mostraron síntomas de presentación que orientan a un estado inflamatorio sistémico, con disnea y tos más frecuentes, y tienen mayor prevalencia de enfermedad grave y neumonía, así como mayor riesgo de desarrollar síntomas persistentes, sobre todo si las personas son mujeres y sedentarias.

ABSTRACT INTRODUCTION In Argentina, obesity in adults is a problem with an average prevalence of 25.4%. The relationship between COVID-19 and obesity shows a higher prevalence of overweight/obesity and severe disease among patients with COVID-19. Therefore, the objective of the study was to know the clinical and epidemiological characteristics of patients diagnosed with obesity who survived SARSCoV- 2 infection. METHODS A descriptive and analytical cross-sectional observational study was carried out. A self-administered survey was applied. RESULTS The median age was 41 years and 69.9% were women. The most prevalent presenting symptoms were asthenia (86.7%), anosmia (64.5%) and cough (64%). Regarding persistent symptoms 12 weeks after diagnosis, the most prevalent ones were asthenia (52.9%), sleep disorders (32.4%) and lack of concentration/memory (31.7%). The risk was higher for women (OR: 2.865; CI95%: 2.23-3.67) with obesity (OR: 1.58; CI95%: 1.16-2.16). Severe disease in obese was almost threefold that in non-obese patients (15.7% vs. 5.4%; p<0.001). DISCUSSION Obese patients showed presenting symptoms that point to a systemic inflammatory state, with dyspnea and cough being more common, and have a higher prevalence of severe disease and pneumonia, as well as a higher risk of developing persistent symptoms, especially if they are women and sedentary.

RESUMEN

Introduction: In March 2020, the World Health Organization (WHO) declared a pandemic for coronavirus 19. Typical symptoms were fever, cough, asthenia, dyspnea, and muscle pain. Pulmonary and central nervous system compromise presented challenging characteristics for healthcare physicians. The objectives of this study were to identify epidemiological and clinical characteristics of SARS-COV-2 infection survivors in a region of Argentina and to determine differences between gender, age groups, year of infection, and evolution time since diagnosis. Methods: A descriptive and analytical cross-sectional observational study was carried out. A self-administered questionnaire was applied, which was available between August and December 2021. Results: Among 1868 individuals included, the mean age was 39.4 ± 13.9 years, and 72.8% were female. Arterial hypertension was the most frequent comorbidity (11.7%). The majority were outpatients (81.9%). The most frequent presentation symptoms at all ages were asthenia (83.7%), fever (54.9%), headache (60.8%), anosmia (64.8%), ageusia (53.2%), cough (54.4%) and myalgias (53.7%). For the 18 to 29 years old age group, the most prevalent presentation symptoms were: headache (69.4%), anosmia (69.1%), ageusia (60.2%), odynophagia (45%), and rhinitis/nasal congestion (46.9%). In the 30 to 64 years old age group, there was a higher prevalence of myalgias (55.8%), arthralgias (41%), and concentration/memory disorder (28.3%). Male showed higher prevalence of fever (64.9% versus 51.1%; p < 0.001) and pneumonia (23.5% versus 13.4%; p < 0.001). After 12 weeks from diagnosis, 38.1% of patients persisted with asthenia, 23.6% with anosmia/dysosmia, and 21.2% with concentration/memory disorders. Conclusions: Systemic symptoms were common to all age groups with coronavirus 19 disease; however, younger, and intermediate age groups presented a higher prevalence of central nervous system symptoms such as anosmia and cognitive disorders, respectively. Symptoms beyond 12 weeks of diagnosis reached slightly more than 10% of the participants.

Introducción: En marzo de 2020 la enfermedad por coronavirus 19 fue declarada pandemia por la Organización Mundial de la Salud. Los síntomas más comunes fueron fiebre, tos, astenia, disnea y dolor muscular. Los compromisos pulmonar y del sistema nervioso central presentaron características desafiantes para los médicos asistenciales. Los objetivos del estudio fueron conocer las características epidemiológicas y clínicas de sobrevivientes a infección por SARS-CoV-2 en una región de Argentina, y determinar las diferencias entre género, grupos etarias, año de contagio, tiempo de evolución desde el diagnóstico. Métodos: Se realizó un estudio observacional descriptivo y analítico de corte transversal. Se aplicó un cuestionario auto administrado, que estuvo disponible entre agosto y diciembre de 2021. Resultados: La media de edad fue de 39,4 ± 13,9 años, el 72,8% fueron mujeres. La comorbilidad más frecuente fue hipertensión arterial (11,7%). La mayoría de los pacientes fueron ambulatorios (81,9%). Los síntomas de presentación más frecuentes a cualquier edad, fueron astenia (83,7%), fiebre (54,9%), cefalea (60,8%), anosmia (64,8%), ageusia (53,2%), tos (54,4%) y mialgias (53,7%). Para el grupo de 18 a 29 años los síntomas de presentación más prevalentes fueron cefalea (69,4%), anosmia 69,1%), ageusia (60,2%), odinofagia (45%) y rinitis/congestión nasal (46,9%). En el grupo de 30 a 64 años se observó mayor prevalencia de mialgias (55,8%), artralgias (41%), falta de concentración/memoria (28,3%). Los hombres mostraron más prevalencia de fiebre (64,9% versus 51,1%; p < 0,001) y neumonía (23,5% versus 13,4%; p < 0,001). Luego de las 12 semanas del diagnóstico 38,1% de los pacientes persistían con astenia, 23,6% con anosmia/disosmia y 21,2% con trastornos de concentración/memoria. Conclusiones: La enfermedad por coronavirus 19 presenta un patrón de síntomas sistémicos común a todos los grupos etarios. No obstante, los grupos más jóvenes presentan más prevalencia de síntomas de afección del sistema nervioso central como la anosmia y los grupos intermedios, mayor prevalencia de trastornos cognitivos. Los síntomas más allá de las 12 semanas del diagnóstico alcanzaron a algo más del 10% de los participantes.

RESUMEN

INTRODUCCIÓN: El tabaquismo es la principal causa de muerte evitable en el mundo. En Argentina, el tabaco explica unas 40 000 muertes anuales, en su mayoría por enfermedades cardiovasculares, respiratorias y cáncer. La primera acción que propone la Organización Mundial de la Salud es el monitoreo, con el fin de obtener la información necesaria sobre la evolución de esta epidemia. OBJETIVOS: Conocer las características relacionadas con el hábito de fumar en la población estable de la ciudad de Cipolletti. MÉTODOS: Se realizó un estudio de corte transversal mediante una encuesta validada previamente. La población estuvo compuesta por mayores de 18 años con más de 10 años de residencia en la ciudad de Cipolletti. Se relevaron indicadores como: fumador actual, exposición al humo de tabaco ajeno, edad de comienzo del hábito y relación con otros factores de riesgo. RESULTADOS: El 57,2% (IC95%: 54,3- 60,1%) reconoció haber fumado alguna vez, y el 20,2% (IC95%: 17-23,9%) fumaba tabaco en el momento de la encuesta: 22,9% (IC95%: 18,9-27,3%) entre los hombres y 18,4% (IC95%: 15,5- 21,8%) entre las mujeres. La edad promedio de comienzo del hábito fue 17,8±7,8 años. CONCLUSIONES: Se observó una diferencia significativa de fumadores actuales frente a los reportes históricos tanto nacionales como regionales y provinciales. Este estudio aporta valiosa información para diseñar acciones de intervención en la población de la ciudad y probablemente de la región.

INTRODUCTION: Smoking is the leading cause of preventable death worldwide. In Argentina, smoking causes about 40,000 deaths annually, mostly from cardiovascular diseases, respiratory diseases and cancer. The first action proposed by the World Health Organization is monitoring in order to have the necessary information on the evolution of this epidemic. OBJECTIVES: To know the characteristics related to smoking habit in Citizens of Cipolletti City. METHODS: A cross-sectional study was carried out through a previously validated survey. The population was composed by people older than 18 living in Cipolletti for more than 10 years. The analyzed indicators were: current smoker, exposure to secondhand smoke, age at starting smoking and relationship with other risk factors. RESULTS: A total of 57.2% (CI95: 54.3-60.1%) of the population admitted having smoked at some point, and 20.2% (CI95: 17.0-23.9%) were current smokers at the time of the study: 22.9% (CI95: 18.9-27.3%) among men and 18.4% (CI95%: 15.5-21.8%) among women. The average age at starting smoking was 17.8±7.8 years. CONCLUSIONS: A significant difference in terms of current smokers was observed, comparing to historical reports at national, regional and provincial levels. This study provides valuable information to design interventions in the population of the city and probably the region.

RESUMEN

INTRODUCCIÓN: la detección precoz del cáncerde mama y cuello de útero en la mujer ha permitido aumentarla sobrevida y aun la curación en estas dos afecciones. Tanto lamamografía como la realización del Papanicolau (PAP) tienen unaadecuada sensibilidad y especificidad para la detección de tumoresincipientes. OBJETIVOS: conocer las prevalencias de utilizaciónde mamografía y PAP en la población femenina de la ciudad deCipolletti. MÉTODOS: Se realizó un estudio de prevalencia. Seincluyeron mujeres mayores de 18 años, no institucionalizadasy con más de 10 años de residencia. Los principales indicadoresfueron: realización de PAP y mamografía en los últimos dos años.RESULTADOS: Participaron del estudio 642 mujeres encuestadasefectivamente con edad promedio 50,24 +/-16,73 años y un rangoentre 18 y 91 años. El 76,7% (IC95%: 67,1-84,1%) de entre 50 y70 años había utilizado la mamografía, y el 74,9% (IC95%: 66,7-81,6%) de entre 25 y 65 se había realizado el Pap en los últimos 2años. Ambos indicadores resultaron mejores que en la Provinciade Río Negro. CONCLUSIONES: Si bien no todas las diferenciasdetectadas fueron estadísticamente significativas, se observa unatendencia a mayor prevalencia de realización de mamografía enCipolletti que en el resto de la provincia, la región y el país.

INTRODUCTION: early detection of breast cancer andcervix cancer in women has led to increased survival and evencure these diseases. Both mammography and Papanicolau (Pap)smear have adequate sensitivity and specificity for detection at earlystage these tumors. OBJECTIVES: To know the prevalence of use ofmammography and Pap smear in screening for breast cancer andcervix cancer in female population of the city of Cipolletti. METHODS:A cross sectional study was carried out. The population includedresidents of city of Cipolletti, older than 18 years, not institutionalizedand more than 10 years of residence. The main indicators wereperformed Pap smear and mammogram in the past two years.RESULTS: The study surveyed 642 women with an average age of50.24 +/- 16.73 years, with a range of age between 18 and 91 years.Mammogram was used in group included in current recommendationsin Argentina between 50 and 70 years in 76.7% (95% CI67.1% -84.1%) and Pap smear was used in 74.9% (CI95 % 66.7%-81.6%) of participants between 25 and 65 years, in the past 2years. Both indicators were better than they were in the Provinceof Río Negro. CONCLUSIONS: Although not all detected differencesare statistically significant, there is a higher use of mammographyin Cipolletti than in the province, the region and also the country.

RESUMEN

BACKGROUND: We previously reported that there was no significant difference at 30 days or at 1 year in the rate of the composite outcome of death, stroke, myocardial infarction, or renal failure between patients who underwent coronary-artery bypass grafting (CABG) performed with a beating-heart technique (off-pump) and those who underwent CABG performed with cardiopulmonary bypass (on-pump). We now report the results at 5 years (the end of the trial). METHODS: A total of 4752 patients (from 19 countries) who had coronary artery disease were randomly assigned to undergo off-pump or on-pump CABG. For this report, we analyzed a composite outcome of death, stroke, myocardial infarction, renal failure, or repeat coronary revascularization (either CABG or percutaneous coronary intervention). The mean follow-up period was 4.8 years. RESULTS: There were no significant differences between the off-pump group and the on-pump group in the rate of the composite outcome (23.1% and 23.6%, respectively; hazard ratio with off-pump CABG, 0.98; 95% confidence interval [CI], 0.87 to 1.10; P=0.72) or in the rates of the components of the outcome, including repeat coronary revascularization, which was performed in 2.8% of the patients in the off-pump group and in 2.3% of the patients in the on-pump group (hazard ratio, 1.21; 95% CI, 0.85 to 1.73; P=0.29). The secondary outcome for the overall period of the trial - the mean cost in U.S. dollars per patient - also did not differ significantly between the off-pump group and the on-pump group ($15,107 and $14,992, respectively; between-group difference, $115; 95% CI, -$697 to $927). There were no significant between-group differences in quality-of-life measures. CONCLUSIONS: In our trial, the rate of the composite outcome of death, stroke, myocardial infarction, renal failure, or repeat revascularization at 5 years of follow-up was similar among patients who underwent off-pump CABG and those who underwent on-pump CABG.

RESUMEN

Los estudiantes se diferencian en sus preferencias de los estilos (modalidades) para aprender. Los estilos de aprendizaje han ganado un lugar de importancia entre los docentes en los diferentes niveles de educación. Conocerlas puede mejorar no sólo el enfoque del estudiante en particular, de la producción de cursos de capacitación, escritura de libros o materiales de enseñanza, sino, también, del ambiente y los procesos educativos. Realizamos este estudio para conocer las preferencias de estilos de aprendizaje de nuestros estudiantes en el Departamento de Salud Colectiva de la Carrera de Medicina de la Universidad Nacional del Comahue. Se realizó un estudio de diseño transversal. Participaron 95 estudiantes de la cátedra de Fisiopatología del año 2014. Fue utilizado el cuestionario VARK. Fueron 69% mujeres y 31% hombres. Cuando se realizó la comparación de las modalidades de acuerdo con el sexo, se observó mayor proporción de hombres con modalidad unimodal (48%) que de mujeres (27%). Del total, el 33.7% presentó un modalidad unimodal; al realizar la agrupación de modalidades, el 40% fue bimodal, el 20% trimodal y el 6.3% cuatrimodal. Del 40% que presentó preferencia bimodal, el 36% fue la combinación de auditivo/lectoescritura, seguido por el 26% que fue auditivo/cinestésico. Los resultados nos muestran que la mayoría de nuestros estudiantes tuvieron un modo multimodal de aprendizaje. Se destacan dos preferencias sensoriales, la auditiva y la cinestésica, seguida por la lectoescritura y, por último, la modalidad visual. No todos aprendemos de la misma manera, esto lo debemos tener en cuenta para diseñar las estrategias de enseñanza a nuestros estudiantes. El conocimiento de las modalidades de aprendizaje en nuestros estudiantes nos muestra que el diseño propuesto de técnicas de enseñanza aprendizaje que estamos utilizando sería adecuado a ellas

Students differ in their preferences for learning styles (modalities). Knowledge about learning styles among students has become a relevant issue for teachers from all educational levels. Therefore, knowing those preferences would allow teachers not only to focus on development of training programs, textbooks and educational materials but also on the teaching-learning process. We conducted this study to determine the preferences of learning styles of our students from the Collective Health Department at the School of Medicine of the Universidad Nacional del Comahue. It was a cross-sectional study involving ninety-five students from the 2014 Pathophysiology course. The VARK questionnaire was used. 69% of students were women and 31% were men. When comparing the styles according to gender a greater proportion of men showed unimodal modality (48%), while 33.7% of students presented a unimodal mode of learning. On the other hand, of those who presented more than one modality of learning, 40% preferred bimodal style, 20% trimodal and 6.3% cuatrimodal. Of the 40% presenting a bimodal modality, 36% were a combination between auditory/reading-writing and 26% were auditory/kinesthetic. The results showed that most of our students used a multimodal form of learning. The most common sensory preferences were auditory and kinesthetic, secondly reading-writing, and lastly the visual mode. We do not all learn in the same way, and this must be borne in mind when designing teaching strategies for our students. Knowledge of their styles of learning shows us that the teaching and learning techniques we are using appear to be adequate

RESUMEN

INTRODUCCIÓN: la enfermedad vascular y los eventos asociados constituyen una de las primeras causas de morbilidad y mortalidad en adultos. En Argentina los eventos cardiovascularesfueron la principal causa de muerte entre 2006 y 2009. Los factores de riesgo son conocidos, y su detección y modificación ayudan a disminuir los eventos vasculares. OBJETIVOS:Determinar la prevalencia de factores de riesgo de enfermedad vascular en la población adulta de Cipolletti y relacionarlos con la Encuesta Nacional (ENFR) de 2009. MÉTODOS: Se realizó un estudio de corte transversal. Los datos se obtuvieron a través de unaencuesta estructurada y validada. Se incluyó a la población mayor de 18 años. Se relevaron los principales factores de riesgo para enfermedad vascular. RESULTADOS: El 58,2% de la población no realizaba el nivel mínimo recomendado de actividad física, el 60,4% presentaba un índice de masa corporal >25, el 15,9% eran fumadores activos y el 14,7% estaba expuesto pasivamente al humo de tabaco. Hubo 41% de prevalencia de presión arterialelevada, 36,6% de colesterol elevado y 14,7% de diabetes/hiperglucemia.Comparando con la ENFR de 2009, existieron prevalencias más elevadas y diferencias estadísticamente significativas en diversos marcadores. CONCLUSIONES: Las iniciativas suelenser nacionales o provinciales, pero deberían ser abordadas por lascomunas locales y con un esfuerzo conjunto entre el sector público, el privado y actores reconocidos dentro de la comunidad.

INTRODUCTION: vascular diseases and related events are one of the leading causes of morbidity and mortalityin adults. In Argentina, cardiovascular events were the leading cause of death between 2006 and 2009. Risk factorsare well-known; their detection and modification help reduce vascular events. OBJECTIVES: To determine the prevalence of vascular disease risk factors in the adult population ofCipolletti, and to relate them with the National Survey of Risk Factors (ENFR) of 2009. METHODS: A cross-sectionalstudy was performed. Data were collected with a structured and validated questionnaire, including people aged over 18 and analyzing the main risk factors for vascular disease.RESULTS: According to the main indicators, 58.2% of the population did not meet the minimum level of recommended physical activity, 60.4% had a body mass index >25, 15.9%were active smokers and 14.7% were passively exposed to tobacco smoke. The prevalence of high blood pressure was 41%, high cholesterol 36.6% and diabetes/hyperglycemia 14.7%. Comparing with the ENFR of 2009, there were higher prevalences and statistically significant differences in several parameters. CONCLUSIONS: Initiatives usually take place atnational or provincial level, but they should be addressed by local communities, with joint efforts of public sector, private sector and different actors recognized within the community.

RESUMEN

BACKGROUND: Previously, we reported that there was no significant difference at 30 days in the rate of a primary composite outcome of death, myocardial infarction, stroke, or new renal failure requiring dialysis between patients who underwent coronary-artery bypass grafting (CABG) performed with a beating-heart technique (off-pump) and those who underwent CABG performed with cardiopulmonary bypass (on-pump). We now report results on quality of life and cognitive function and on clinical outcomes at 1 year. METHODS: We enrolled 4752 patients with coronary artery disease who were scheduled to undergo CABG and randomly assigned them to undergo the procedure off-pump or on-pump. Patients were enrolled at 79 centers in 19 countries. We assessed quality of life and cognitive function at discharge, at 30 days, and at 1 year and clinical outcomes at 1 year. RESULTS: At 1 year, there was no significant difference in the rate of the primary composite outcome between off-pump and on-pump CABG (12.1% and 13.3%, respectively; hazard ratio with off-pump CABG, 0.91; 95% confidence interval [CI], 0.77 to 1.07; P=0.24). The rate of the primary outcome was also similar in the two groups in the period between 31 days and 1 year (hazard ratio, 0.79; 95% CI, 0.55 to 1.13; P=0.19). The rate of repeat coronary revascularization at 1 year was 1.4% in the off-pump group and 0.8% in the on-pump group (hazard ratio, 1.66; 95% CI, 0.95 to 2.89; P=0.07). There were no significant differences between the two groups at 1 year in measures of quality of life or neurocognitive function. CONCLUSIONS: At 1 year after CABG, there was no significant difference between off-pump and on-pump CABG with respect to the primary composite outcome, the rate of repeat coronary revascularization, quality of life, or neurocognitive function.

RESUMEN

BACKGROUND: The relative benefits and risks of performing coronary-artery bypass grafting (CABG) with a beating-heart technique (off-pump CABG), as compared with cardiopulmonary bypass (on-pump CABG), are not clearly established. METHODS: At 79 centers in 19 countries, we randomly assigned 4752 patients in whom CABG was planned to undergo the procedure off-pump or on-pump. The first coprimary outcome was a composite of death, nonfatal stroke, nonfatal myocardial infarction, or new renal failure requiring dialysis at 30 days after randomization. RESULTS: There was no significant difference in the rate of the primary composite outcome between off-pump and on-pump CABG (9.8% vs. 10.3%; hazard ratio for the off-pump group, 0.95; 95% confidence interval [CI], 0.79 to 1.14; P=0.59) or in any of its individual components. The use of off-pump CABG, as compared with on-pump CABG, significantly reduced the rates of blood-product transfusion (50.7% vs. 63.3%; relative risk, 0.80; 95% CI, 0.75 to 0.85; P<0.001), reoperation for perioperative bleeding (1.4% vs. 2.4%; relative risk, 0.61; 95% CI, 0.40 to 0.93; P=0.02), acute kidney injury (28.0% vs. 32.1%; relative risk, 0.87; 95% CI, 0.80 to 0.96; P=0.01), and respiratory complications (5.9% vs. 7.5%; relative risk, 0.79; 95% CI, 0.63 to 0.98; P=0.03) but increased the rate of early repeat revascularizations (0.7% vs. 0.2%; hazard ratio, 4.01; 95% CI, 1.34 to 12.0; P=0.01). CONCLUSIONS: There was no significant difference between off-pump and on-pump CABG with respect to the 30-day rate of death, myocardial infarction, stroke, or renal failure requiring dialysis. The use of off-pump CABG resulted in reduced rates of transfusion, reoperation for perioperative bleeding, respiratory complications, and acute kidney injury but also resulted in an increased risk of early revascularization.

RESUMEN

BackgroundThe relative benefits and risks of performing coronary-artery bypass grafting (CABG) with a beating-heart technique (off-pump CABG), as compared with cardiopulmonarybypass (on-pump CABG), are not clearly established.MethodsAt 79 centers in 19 countries, we randomly assigned 4752 patients in whom CABG was planned to undergo the procedure off-pump or on-pump. The first coprimary outcome was a composite of death, nonfatal stroke, nonfatal myocardial infarction, or new renal failure requiring dialysis at 30 days after randomization.ResultsThere was no significant difference in the rate of the primary composite outcomebetween off-pump and on-pump CABG (9.8% vs. 10.3%; hazard ratio for the offpump group, 0.95; 95% confidence interval [CI], 0.79 to 1.14; P = 0.59) or in any of its individual components. The use of off-pump CABG, as compared with on-pump CABG, significantly reduced the rates of blood-product transfusion (50.7% vs. 63.3%; relative risk, 0.80; 95% CI, 0.75 to 0.85; P<0.001), reoperation for perioperative bleeding(1.4% vs. 2.4%; relative risk, 0.61; 95% CI, 0.40 to 0.93; P = 0.02), acute kidney injury (28.0% vs. 32.1%; relative risk, 0.87; 95% CI, 0.80 to 0.96; P = 0.01), and respiratorycomplications (5.9% vs. 7.5%; relative risk, 0.79; 95% CI, 0.63 to 0.98; P = 0.03) but increased the rate of early repeat revascularizations (0.7% vs. 0.2%; hazard ratio, 4.01; 95% CI, 1.34 to 12.0; P = 0.01).ConclusionsThere was no significant difference between off-pump and on-pump CABG with respect to the 30-day rate of death, myocardial infarction, stroke, or renal failure requiring dialysis.
