ABSTRACT A 59-year-old man presented with a unilateral blurring of vision in his left eye. His left eye’s visual acuity was hand movements level. He underwent phacoemulsification surgery, and an intrastromal posterior chamber intraocular lens was implanted. The intrastromal intraocular lens was extracted and a new intraocular lens was implanted. Usinge the Snellen chart, the final best-corrected visual acuity was 20/40. With this case report, we wish to emphasize that a single stepwise clear corneal incision merged with wound-assisted intraocular lens injections can result in intraocular lens misdirection into the corneal stroma. As a result, while performing a misdirected intraocular lens removal, we recommend that the wound be carefully constructed.

RESUMO Um homem de 59 anos apresentou embaçamento visual unilateral no olho esquerdo. Sua acuidade visual nesse olho era no nível de movimentos da mão. O paciente havia se submetido a uma cirurgia de facoemulsificação em que foi feita a implantação intraestromal de uma lente intraocular de câmara posterior. Foi feita a extração dessa lente intraestromal intraocular e uma nova lente intraocular foi implantada. A melhor acuidade visual corrigida final foi de 20/40 pela tabela de Snellen. Com este relato de caso, os autores desejam apontar que uma incisão de degrau único em córnea clara, quando combinada com a injeção de uma lente ocular através da incisão, pode levar a um direcionamento incorreto da lente intraocular para dentro do estroma corneano. Portanto, recomenda-se uma construção cuidadosa da incisão ao se remover uma lente intraocular direcionada incorretamente.

Abstract Objective: To investigate the safety and cost-effectiveness of preoperative cannulation and conventional approach techniques. Methods: Sixty-one patients who underwent redo open cardiac procedures between September 2015 and November 2018 were divided into two groups - Group A (n: 30), patients who underwent conventional cannulation after sternotomy, and Group B (n: 31), those who underwent cannulation before sternotomy. Patients were evaluated retrospectively for general complication rates and total hospital costs. Results: Mortality occurred in four patients from Group A and in one patient from Group B. Four patients required extracorporeal membrane oxygenation (ECMO) in Group A, whereas two required ECMO in Group B. Duration of total operation, cardiopulmonary bypass, and cross-clamp times were longer in the conventional surgery group than in the pre-sternotomy cannulation group (420.29±188.84 vs. 314.77±187.38, P=0.036; 171.87±85.59 vs. 141.7±82.47, P=0.089; and 102.94±70.67 vs. 60.97±52.81, P=0.009; respectively). Total blood and blood product usage were higher in Group A than in Group B. Postoperative intensive care unit stay was 62.77±145.3 hours vs. 25.13±73.11 hours, ventilation time was 5.16±5.09 hours vs. 3.03±2.78 hours, duration of ward stay was 5.23±2.52 days vs. 5.57±2.16 days, and duration of hospital stay was 9.58±5.85 days vs. 9.8±5.31 days in conventional sternotomy and pre-sternotomy cannulation groups, respectively. Total hospital costs were calculated 35863.52±20803.99 Turkish Liras (TL) in Group A and 25744.74±16472.03 TL in Group B (P=0,042). Conclusion: Venous and arterial cannulations before sternotomy decreased myocardial injury and complication rates, blood and blood product usage, hospital stay, and, consequently, hospital costs in our modest cohort.

Abstract Objective: To detect and to compare the apoptotic effects of intraoperatively topically applied diltiazem, papaverine, and nitroprusside. Methods: Internal thoracic artery segments of ten patients were obtained during coronary bypass grafting surgery. Each internal thoracic artery segment was divided into four pieces and immersed into four different solutions containing separately saline (Group S), diltiazem (Group D), papaverine (Group P), and nitroprusside (Group N). Each segment was examined with both hematoxylin-eosin and the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) method in order to determine and quantify apoptosis. Results: Apoptotic cells were counted in 50 microscopic areas of each segment. No significant difference was observed among the four groups according to hematoxylin-eosin staining. However, the TUNEL method revealed a significant increase in mean apoptotic cells in the diltiazem group when compared with the other three groups (Group S=4.25±1.4; Group D=13.31±2.8; Group N=9.48±2.09; Group P=10.75±2.37). The differences between groups were significant (P=0.0001). No difference was observed between the samples of the diabetic and non-diabetic patients in any of the study groups. Conclusion: The benefit of topically applied vasodilator drugs must outweigh the potential adverse effects. In terms of apoptosis, diltiazem was found to have the most deleterious effects on internal thoracic artery graft segments. Of the analyzed medical agents, nitroprusside was found to have the least apoptotic activity, followed by papaverine. Diabetes did not have significant effect on the occurrence of apoptosis in left internal thoracic artery grafts.

Resumen Se registra el estudio de la flora bacteriana de cuatro importantes plagas de álamo, Cryptorhynchus lapathi (Coleoptera: Curculionidae), Sciapteron tabaniformis Rott (Lepidoptera: Sesiidae), Nycteola asiatica (Lepidoptera: Nolidae) y Gypsonoma dealbana (Lepidoptera: Tortricidae) en la búsqueda de agentes de control ecológicamente alternativos contra las plagas del álamo y disminuir los efectos indeseables causados por los plaguicidas químicos en el área urbana y los bosques urbanos. Se aislaron e identificaron cuarenta y tres bacterias de las larvas y adultos de estas plagas a partir de cinco localidades diferentes. Todos los aislados bacteriales fueron cultivados e identificados usando los sistemas VITEK (VITEK® 2 GN ID card prod. no; 21341 and VITEK® 2 GP ID card prod. no; 21342, bioMerieux, Marcy l’Etoile). Los miembros de los géneros de las familias Bacillaceae y Enterobacteriaceae fueron aislados con más frecuencia de ambos insectos de la plaga.

Abstract In this study, the bacterial flora of important poplar pests was studied. This included Cryptorhynchus lapathi (Coleoptera: Curculionidae), Sciapteron tabaniformis (Lepidoptera: Sesiidae), Nycteola asiatica (Lepidoptera: Noli- dae) and Gypsonoma dealbana (Lepidoptera: Tortricidae). The final goal was to propose alternative ecological control agents for poplar pests and decrease the undesirable effects caused by chemical pesticides in urban areas and urban forests. Forty-three bacteria were isolated from the larvae and adults exhibiting characteristic disease symptoms of these pests in five different localities for the first time. All bacterial isolates were cultured and identified using VITEK bacterial identification systems (VITEK® 2 GN ID card prod. no; 21341 and VITEK® 2 GP ID card prod. no; 21342, bioMerieux, Marcy l’Etoile). The members of the genera from Bacillaceae and Enterobacteriaceae families were most commonly isolated from both pest insects.

Resumo Objetivos: A disfunção cognitiva no pós-operatório refere-se a problemas associados ao pensamento e à memória que são frequentemente manifestados após uma cirurgia de grande porte. O objetivo deste estudo foi avaliar os efeitos da memantina administrada por via intraperitoneal sobre a recuperação, as funções cognitivas e a dor após a anestesia com propofol. Métodos: O estudo foi feito no Laboratório de Pesquisa com Animais da Universidade de Gazi, Ankara, Turquia, em janeiro de 2012. Vinte e quatro ratos albinos do sexo feminino, adultos, da linhagem Wistar, com 170-270 g, foram treinados durante 300 segundos no labirinto radial de oito braços (LRB) durante três dias. O Grupo P recebeu 150 mg/kg−1 de propofol por via intraperitoneal (IP), o Grupo H recebeu 1 mg/kg−1 de memantina IP e o Grupo MP recebeu 1 mg/kg−1 de memantina IP antes da administração de 150 mg/kg−1 de propofol (IP). O grupo controle recebeu apenas solução salina IP. Os valores do LRB e da placa quente foram obtidos após a recuperação dos grupos que receberam propofol e 30 minutos após a administração dos fármacos nos outros dois grupos. Resultados: O tempo de recuperação do Grupo MP foi significativamente menor do que o do Grupo P (p < 0,001) e o número de entradas e saídas do LRB do Grupo MP foi significativamente maior durante a primeira hora, em comparação com o Grupo P (p < 0,0001). Os valores da placa quente, por outro lado, foram significativamente maiores em todos os grupos, em comparação com os valores do grupo controle, exceto pelo Grupo C (p < 0,0001). Conclusão: No presente estudo, memantina proporcionou tempos mais curtos de recuperação, funções cognitivas melhores e reduziu a dor no pós-operatório. A partir deste estudo, descobrimos que a memantina tem efeitos benéficos sobre a recuperação, as funções cognitivas e a dor após anestesia com propofol.

Abstract Objectives: Postoperative cognitive dysfunction refers to the problems associated with thought and memory that are often experienced after major surgery. The aim of this study is to evaluate the effects of intraperitoneally administered memantine on recovery, cognitive functions, and pain after propofol anesthesia. Methods: The study was conducted in Gazi University Animal Research Laboratory, Ankara, Turkey in January 2012. Twenty-four adult female Wistar Albino rats weighing 170-270 g were educated for 300 s in the radial arm maze (RAM) over three days. Group P was administered 150 mg kg−1 of intraperitoneal (IP) propofol; Group M was given 1 mg kg−1 of IP memantine; and Group MP was given 1 mg kg−1 of IP memantine before being administered 150 mg kg−1 of IP propofol. The control group received only IP saline. RAM and hot plate values were obtained after recovery from the groups that received propofol anesthesia and 30 min after the administration of drugs in other two groups. Results: The duration of recovery for Group MP was significantly shorter than Group P (p < 0.001), and the number of entries and exits in the RAM by Group MP was significantly higher during the first hour when compared to Group P (p < 0.0001). Hot plate values, on the other hand, were found to be significantly increased in all groups when compared to the control values, aside from Group C (p < 0.0001). Conclusion: In this study, memantine provided shorter recovery times, better cognitive functions, and reduced postoperative pain. From this study, we find that memantine has beneficial effects on recovery, cognitive functions, and pain after propofol anesthesia.

RESUMO Nosso paciente era um homem de 34 anos que apresentou uma massa conjuntival indolor desde há 3 meses antes da primeira consulta. Na biomicroscopia por lâmpada de fenda, observa-se uma massa rosa-amarelada, sólida, móvel e lobulada na superfície conjuntival bulbar nasal, em seu olho esquerdo. O tumor foi retirado e o exame histopatológico demonstrou um adenoma sebáceo. O exame sistêmico era normal. Nenhuma recidiva foi observada durante os 24 meses de acompanhamento. Adenoma sebáceo da conjuntiva bulbar é um tumor benigno extremamente raro e pode ser visto isolado, sem quaisquer doenças malignas associadas.

ABSTRACT Our patient was a 34 year-old male who presented with a painless conjunctival mass that had developed 3 months before his first visit. On performing slit-lamp biomicroscopy, a lobulated pink-yellowish solid mobile mass was observed on the nasal bulbar conjunctival surface of his left eye. The tumor was excised, and histopathologic examination of the tumor revealed a sebaceous adenoma. Systemic examination was normal. No recurrence was observed during the 24-month follow-up period. Sebaceous adenoma of the bulbar conjunctiva is an extremely rare benign tumor, which may be observed to be isolated in the absence of malignancy.

Uma mulher de 49 anos de idade, com perda visual aguda de seu olho esquerdo, que teve diagnóstico de carcinoma endotelial de pâncreas há dois meses, foi examinada em nossa clínica. Suas acuidades visuais eram 20/20 no olho direito e 20/200 no olho esquerdo. O exame de fundo de olho e a angiofluoresceinografia mostraram massa solitária sub-retiniana bilateral. Múltiplas metástases do pulmão, pleura, fígado, baço e nódulos linfáticos abdominais foram detectados no diagnóstico inicial. A paciente foi submetida a quimioterapia durante o tempo que os sintomas visuais foram observados. Nenhum tratamento adicional foi oferecido por causa da extensão da doença e problemas de saúde em geral. Embora o carcinoma endotelial de pâncreas normalmente se espalhe para órgãos abdominais e pulmões, este pode ser uma causa rara de metástases de coroide.

A 49-year-old woman with acute loss of vision in her left eye was examined in our clinic. Two months before arriving at out clinic, she was diagnosed with pancreatic endothelial carcinoma. Her visual acuities were 20/20 for the right and 20/200 for the left eye. Fundus examination and fundus fluorescein angiography showed bilateral subretinal solitary mass. Multiple metastases to lung, pleura, liver, spleen, and abdominal lymph nodes were detected during the initial diagnosis. The patient underwent chemotherapy during the period when the visual symptoms were observed. No additional treatment was offered because of the extent of the disease and poor general health. Although pancreatic endothelial carcinoma usually spreads to the abdominal visceral organs and lungs, choroidal metastases are rarely observed.

BACKGROUND: Atherosclerosis that starts in childhood invariably advances during adulthood. AIM: We aimed to study the effect of obesity on main carotid artery intima-media thickness (CIMT) and arterial stiffness. MATERIAL AND METHODS: A total of 78 children were studied from October 2010 to February 2011. They were divided into obese (n=42, group 1) and normal (n=36, group 2). All children were subjected to physical examination, routine biochemical and haematological analysis, carotid ultrasonography and echocardiographic measurements. A detailed medical history was obtained. Body mass index (BMI) was calculated by dividing participants' weight in kilograms by the square of their height in metres. Stiffness index β was calculated using blood pressure and diameter of the systolic and diastolic artery. Intima-media thickness was also measured. RESULTS: The mean age of the obese and normal (control) groups was 10.12±2.12 years and 9.78±1.78 years, respectively. Weight, BMI, and systolic and diastolic blood pressure values were significantly higher in the obese group (all p<0.001). In terms of arterial stiffness and CIMT measurements, all parameters were higher in the obese group than the control (p<0.001). There was a relationship between the degree of obesity and CIMT or stiffness index p. In addition, dilatation and hypertrophy levels in the left ventricle were higher in obese children. CONCLUSIONS: Obese children with risk factors for multiple atherosclerosis could have increased CIMT dimensions and, consequently, should be screened for these risks. Ultrasonographic CIMT and arterial stiffness measurements can detect vascular damage at an early stage of development in children with cardiovascular risk factors.

OBJECTIVE: To determine the prevalence of disordered eating (DE) among a group of college students and assess its impact on quality of life. MATERIAL AND METHODS: This study was conducted between December 15th, 2008 and January 15th, 2009 at a Turkish University. Eating Attitudes Test-40 (EAT-40) was used to identify DE. Health Related Quality of Life (HRQoL) was assessed by Medical Outcomes Study Short Form-36. RESULTS: The prevalence of DE was 6.8%. Presence of any physical defect (OR: 2.657), parents living separately (OR: 3.114), mothers having an education level of secondary school and over (OR: 2.583), and families not having social health insurance (OR: 2.603) were important risk factors (f<0.05). CONCLUSIONS: The HRQoL of those with DE was worse than those without it. Periodic screenings should be done to determine DE cases.

PURPOSE: To analyze the effect of maintenance hemodialysis on left ventricular diastolic function in patients with end-stage renal disease. METHODS: Study population consisted of 42 patients with end-stage renal disease. Before an arteriovenous fistula was surgically created, the patients were evaluated by conventional and Doppler echocardiography and Doppler tissue imaging. Then, the patients undergoing hemodialysis treatment when the arteriovenous fistula was compleated. After the first hemodialysis session (mean 76.14 ± 11.37 days) the second echocardiographic evaluations were performed. RESULTS: Mean age was 58 ± 13 years and 21 (%50) of the patients were female. After maintenance hemodialysis treatment; peak early (E) and peak late (A) diastolic mitral inflow velocities and E/A ratio were not significantly change however the deceleration time of E wave and left atrial diameter were significantly increased. Also there was no change in the early (Em) and late (Am) diastolic myocardial velocities and Em/Am ratios of lateral and septal walls of left ventricular. E/Em ratio was decreased insignificantly. Pulmonary vein velocities and right ventricular functions are remained almost unchanged after hemodialysis treatment. DISCUSSION: The acute and long-term effect of hemodialysis on left ventricular diastolic function is unclearly. Patients with end-stage renal disease treatment with hemodialysis via arteriovenous fistula experience a variety of hemodynamic and metabolic abnormalities that predispose to alterations in left and right ventricular functions. The present study showed that left ventricular diastolic function except left atrial diameter and right ventricular functions were not significantly change, however left ventricular systolic functions were impaired after maintenance hemodialysis treatment in patients with end-stage renal disease. CONCLUSION: It has been suggested that echocardiographic parameters are useful markers for evaluation of left ventricular and right ventricular functions in patients with end-stage renal disease. However, in patients with endstage renal disease treated with hemodialysis, repeated assessment of echocardiographic examinations to observe serial changes in left and right ventricular functions are not yet well established. In this study, we showed that acute changes of volume status and electrolytes and autonomic regulation by hemodialysis session did not affect left ventricular diastolic and right ventricular functions in a relatively long term.

FUNDAMENTO: Tem sido demonstrado que diminuições na variabilidade da frequência cardíaca (VFC) estão relacionadas com o prognóstico na insuficiência cardíaca (IC). A administração crônica de trimetazidina, além da terapia convencional, tem melhorado a classe funcional e a função ventricular esquerda de pacientes com IC. OBJETIVO: Avaliar os efeitos da trimetazidina na VFC em pacientes com IC de origem isquêmica, recebendo tratamento otimizado. MÉTODOS: Trimetazidina 20 mg 3 vezes/dia foi adicionada à terapia de 30 pacientes com IC tratados com inibidores da enzima conversora de angiotensinogênio ou bloqueadores do receptor da angiotensina, carvedilol, espironolactona, digital e furosemida. A etiologia da IC era doença arterial coronariana em todos os pacientes. Os pacientes foram avaliados através de ecocardiografia e análise da VFC de 24-horas antes e 3 meses depois da adição de trimetazidina. RESULTADOS: A fração de ejeção ventricular esquerda (FEVE) média aumentou significantemente após a adição da trimetazidina (33,5±5,1% para 42,5±5,8%, p<0,001). Dos parâmetros da VFC, o DPNN (97,3±40,1 to 110,5±29,2 msegs, p=0,049) e DPTNN (80,5±29,0 to 98,3±30,5 msegs) aumentaram significantemente após o tratamento com trimetazidina. O DPNN basal apresentou uma correlação significante com o FEVE basal (r=0,445, p=0,023, p=0,008) e o incremento no DPNN correlacionou-se com o aumento na FEVE (r=0,518, p=0,007). CONCLUSÕES: A trimetazidina, quando adicionada ao tratamento médico otimizado de pacientes com IC de origem isquêmica, pode melhorar a VFC, além de melhorar a fração de ejeção ventricular esquerda.

BACKGROUND: Reduced measures of heart rate variability (HRV) have been shown to be related with prognosis in heart failure. Chronic administration of trimetazidine in addition to the conventional therapy has been shown to improve functional class and left ventricular functions of heart failure patients. OBJECTIVE: To assess the effects of trimetazidine on HRV in optimally treated patients with heart failure of ischemic origin. METHODS: Trimetazidine 20 mg three times/day was added to therapy of 30 patients with heart failure being treated with angiotensinogen converting enzyme inhibitors or angiotensin receptor blockers, carvedilol, spironolactone, digitalis and furosemide. The etiology of heart failure was coronary artery disease in all patients. Patients were evaluated with echocardiography and 24-hour heart rate variability analysis before and 3 months after addition of trimetazidine. RESULTS: Mean left ventricular ejection fraction (LVEF) significantly increased after the addition of trimetazidine (33.5±5.1% to 42.5±5.8%, p<0.001). Of the HRV parameters, SDNN (97.3±40,1 to 110.5±29,2 msecs, p=0.049) and SDANN (80.5±29,0 to 98.3±30,5 msecs) were significantly increased after trimetazidine treatment. Baseline SDNN was significantly correlated with baseline LVEF (r=0.445, p=0.023, p=0.008) and the increment in SDNN was correlated with increase in LVEF (r=0.518, p=0.007). CONCLUSIONS: Adding trimetazidine to optimal medical therapy in patients with heart failure of ischemic origin may improve heart rate variability in association with improved left ventricular ejection fraction.

FUNDAMENTO: Se ha demostrado que disminuciones en la variabilidad de la frecuencia cardíaca (VFC) están relacionadas con el pronóstico en la insuficiencia cardíaca (IC). La administración crónica de trimetazidina, además de la terapia convencional, ha mejorado la clase funcional y la función ventricular izquierda de pacientes con IC. OBJETIVO: Evaluar los efectos de la trimetazidina en la VFC en pacientes con IC de origen isquémico, recibiendo tratamiento optimizado. MÉTODOS: Se agregó trimetazidina 20 mg 3 veces/día a la terapia de 30 pacientes con IC tratados con inhibidores de la enzima conversora de angiotensinógeno o bloqueadores del receptor de la angiotensina, carvedilol, espironolactona, digital y furosemida. La etiología de la IC era enfermedad arterial coronaria en todos los pacientes. Los pacientes fueron evaluados mediante ecocardiografía y análisis de la VFC de 24-horas antes y 3 meses después de la adición de trimetazidina. RESULTADOS: La fracción de eyección ventricular izquierda (FEVI) media aumentó significativamente después de la adición de la trimetazidina (33,5±5,1% para 42,5±5,8%, p<0,001). De los parámetros de la VFC, la SDNN (97,3±40,1 a 110,5±29,2 msegs, p=0,049) y la SDANN (80,5±29,0 a 98,3±30,5 msegs) aumentaron significativamente después del tratamiento con trimetazidina. La SDNN basal presentó una correlación significativa con la FEVI basal (r=0,445, p=0,023, p=0,008) y el incremento en la SDNN se correlacionó con el aumento en la FEVI (r=0,518, p=0,007). CONCLUSIÓN: Cuando se agrega trimetazidina al tratamiento médico optimizado de pacientes con IC de origen isquémico, puede mejorar la VFC, además de mejorar la fracción de eyección ventricular izquierda.

FUNDAMENTO: Devido à sobreposição de sintomas e inadequada capacidade de exercícios, o diagnóstico não-invasivo da doença arterial coronariana (DAC) pode ser sub ou superestimado em pacientes com doença pulmonar obstrutiva crônica (DPOC). OBJETIVO: Avaliar os resultados de angiografias coronarianas em pacientes com DPOC dependendo das características clínicas basais. MÉTODOS: Os registros médicos de 157 pacientes com DPOC e 157 pacientes sem DPOC pareados por características clínicas basais, que haviam sido submetidos a angiografia coronariana diagnóstica pela primeira vez, foram revisados, retrospectivamente. RESULTADOS: A frequência de DAC era significantemente mais baixa em pacientes com DPOC do que no grupo controle (52,8% vs. 80,2%, p<0,001). As frequências dos fatores de risco para DAC (idade avançada, hipertensão, diabete, histórico de fumo) eram significantemente mais comuns entre os pacientes com DPOC que tinham DAC significativa. Entre os pacientes que reportavam angina pectoris estável, DAC significativa foi detectada em 32,7% dos pacientes com DPOC e em 71,0% dos pacientes sem DPOC (p<0,001). Entretanto, para os pacientes com diagnóstico de angina pectoris instável, DAC significativa foi detectada em 87,5% dos pacientes com DPOC e 90,2% dos pacientes sem DPOC (p=0,755). CONCLUSÃO: O diagnóstico de DAC pacientes com DPOC através da sintomatologia, somente, pode ser difícil. Entretanto, o diagnóstico clínico de DAC no quadro de angina instável é acurado na maioria dos pacientes com DPOC. Assim, outros métodos diagnósticos não-invasivos ou seguimento cuidadoso podem ser mais apropriados para pacientes com DPOC que reportam angina pectoris estável.

BACKGROUND: Due to overlapping symptoms and inadequate exercise capacity, noninvasive diagnosis of coronary artery disease (CAD) may be under- or overestimated in patients with chronic obstructive pulmonary disease (COPD). OBJECTIVE: To assess outcomes of coronary angiography in COPD patients depending on baseline clinical characteristics. METHODS: Medical records of 157 patients with COPD and 157 patients without COPD matched for baseline clinical characteristics who had undergone diagnostic coronary angiography for the first time were reviewed retrospectively. RESULTS: The frequency of significant CAD was significantly lower in COPD patients than in the control group (52.8% vs. 80.2%, p<0.001). Frequencies of CAD risk factors (older age, hypertension, diabetes, smoking history) were significantly more frequent among COPD patients having significant CAD. Among patients reporting stable angina pectoris, significant CAD was detected in 32.7% of COPD patients and 71.0% of non-COPD patients (p<0.001). However, among the patients with a diagnosis of unstable angina pectoris, significant CAD was detected in 87.5% of COPD patients and 90.2% of non-COPD patients (p=0.755). CONCLUSION: Diagnosis of CAD in COPD patients by symptomatology may be difficult. However, clinical diagnosis of CAD in the setting of unstable angina is accurate in most of the COPD patients. Therefore, further noninvasive diagnostic methods or careful follow up may be more appropriate for COPD patients reporting stable angina pectoris.

FUNDAMENTO: A causa de la superposición de síntomas e inadecuada capacidad de ejercicios, el diagnóstico no-invasivo de la enfermedad arterial coronaria (EAC) se puede sub o superestimar en pacientes con enfermedad pulmonar obstructiva crónica (EPOC). OBJETIVO: Evaluar los resultados de angiografías coronarias en pacientes con EPOC dependiendo de las características clínicas basales. MÉTODOS: Se revisaron retrospectivamente los registros médicos de 157 pacientes con EPOC y 157 pacientes sin EPOC distribuidos en grupos según características clínicas basales, que se habían sometido a angiografía coronaria diagnóstica por primera vez. RESULTADOS: La frecuencia de EAC era significantemente más baja en pacientes con EPOC que en el grupo control (52,8% vs. 80,2%, p<0,001). Las frecuencias de los factores de riesgo para EAC (edad avanzada, hipertensión, diabetes, histórico de fumo) eran significantemente más comunes entre los pacientes con EPOC que tenían EAC significante. Entre los pacientes que reportaban angina de pecho estable, se detectó EAC significante en un 32,7% de los pacientes con EPOC y el 71,0% de los pacientes sin EPOC (p<0,001). Sin embargo, para los pacientes con diagnóstico de angina de pecho inestable, se detectó EAC significante en un 87,5% de los pacientes con EPOC y un 90,2% de los pacientes sin EPOC (p=0,755). CONCLUSIONES: El diagnóstico de EAC pacientes con EPOC solamente mediante la sintomatología puede ser difícil. Sin embargo, el diagnóstico clínico de EAC en el cuadro de angina inestable resulta preciso en la mayoría de los pacientes con EPOC. Así, otros métodos diagnósticos no-invasivos o seguimiento cuidadoso pueden ser más apropiados para pacientes con EPOC que refieren angina de pecho estable.
