Association of Serum Glucocorticoids with Various Blood Pressure Indices in Patients with Dysglycemia and Hypertension: the Henan Rural Cohort Study / 生物医学与环境科学（英文）

Objective@#To our knowledge, no definitive conclusion has been reached regarding the relationship between glucocorticoids and hypertension. Here, we aimed to explore the characteristics of glucocorticoids in participants with dysglycemia and hypertension, and to analyze their association with blood pressure indicators.@*Methods@#The participants of this study were from the Henan Rural Cohort study. A total of 1,688 patients 18-79 years of age were included in the matched case control study after application of the inclusion and exclusion criteria. Statistical methods were used to analyze the association between glucocorticoids and various indices of blood pressure, through approaches such as logistic regression analysis, trend tests, linear regression, and restricted cubic regression.@*Results@#The study population consisted of 552 patients with dysglycemia and hypertension (32.7%). The patients with co-morbidities had higher levels of serum cortisol ( @*Conclusions@#Serum deoxycortisol was positively correlated with systolic blood pressure, pulse pressure, mean arterial pressure, mean blood pressure, and mean proportional arterial pressure. Glucocorticoids (deoxycortisol and cortisol) increase the risk of hypertension in people with dysglycemia, particularly in those with T2DM.

Valor de corte del índice cintura/cadera como predictor independiente de disglucemias / Cutoff value of the waist-hip ratio as an independent predictor of dysglycemia

RESUMEN Introducción: En Cuba, no existe consenso acerca de qué valor del índice cintura/cadera debe ser considerado de riesgo para identificar disglucemias. Objetivos: Determinar el punto de corte del índice cintura/cadera como predictor de disglucemias para ambos sexos, en personas con sospecha de padecer diabetes mellitus. Métodos: Estudio descriptivo transversal con 975 personas, de ellas 523 mujeres y 452 hombres. La muestra no fue obtenida de población general y no fue aleatoria. A los sujetos se les realizó interrogatorio, examen físico y estudios complementarios. Se determinaron distribuciones de frecuencia de las variables cualitativas y cuantitativas. Se utilizó para el procesamiento estadístico el coeficiente de correlación de Pearson, análisis de regresión logística y el análisis de curvas Receiver Operator Characteristic. Se empleó la prueba Chi Cuadrado para evaluar la significación estadística. Resultados: En ambos sexos observamos una correlación directamente proporcional y significativa entre el índice cintura/cadera y las diferentes variables estudiadas, entre ellas: glucemia en ayunas y a las 2h, insulinemia en ayunas, triglicéridos, ácido úrico y el índice de resistencia a la insulina (HOMA-IR). El colesterol se comportó de la misma forma en los hombres, pero en las mujeres se verificó una correlación débil y no significativa. El punto de corte óptimo del índice cintura/cadera, como predictor independiente de disglucemias, fue de 0,85 en las mujeres y 0,93 en los hombres. El índice cintura/cadera presentó un buen poder predictivo para identificar a sujetos con y sin disglucemias para ambos sexos y superior al de la edad. Conclusiones: El punto de corte óptimo del índice cintura/cadera, como predictor independiente de disglucemias, es de 0,85 en las mujeres y 0,93 en los hombres. Su poder predictor de disglucemias fue bueno(AU)

ABSTRACT Introduction: In Cuba, there is no consensus about what value of the waist-hip ratio must be considered as a risk to identify dysglycemia. Objectives: To determine the cut-off point of the waist-hip ratio as a predictor of dysglycemias for both sexes, in people suspected of suffering from diabetes mellitus. Methods: Descriptive cross-sectional study with 975 people, including 523 women and 452 men. The sample was not obtained from general population and it was not random. The subjects underwent interrogation, physical examination and complementary studies. There were identified frequency distributions of qualitative and quantitative variables. It was used for the statistical processing the Pearson's correlation coefficient, logistic regression analysis and the curves analysis called Receiver Operator Characteristic. It was used the chi-square test to assess the statistical significance. Results: In both sexes, it was observed a directly proportional and significant correlation between the waist-hip ratio and the different variables studied, including: fasting and after 2 hours glycemia, fasting insulinemia, triglycerides, uric acid and the insulin resistance index (HOMA-IR). Cholesterol behaved the same way in men, but in women there was a weak and not significant correlation. The optimal cut-point of the waist-hip ratio, as an independent predictor of dysglycemia, was 0.85 in women and 0.93 in men. The waist-hip ratio presented a good predictive power to identify subjects with and without dysglycemia for both sexes and it was higher than that of the age. Conclusions: The optimal cut-point of the waist-hip ratio, as an independent predictor of dysglycemia, was 0.85 in women and 0.93 in men. Its power as predictor of dysglycemia was good(AU)

A simple screening tool to identify women with previously undiagnosed prediabetes and diabetes mellitus in the community

Background:In the current context of rising prevalence of non-communicable diseases, simple low-cost screening tools are essential for identifying individuals who have glucose dysregulationat its early stages. Therefore, we developed and validated a screening tool for dysglycemia (defined as HbA1c≥5.7%) with the potential to identify undiagnosed prediabetes and as well as diabetes mellitus.Methods:A sample of 2800 women representative ofColombo Municipal Council area was screened using fasting blood glucose for dysglycemia. All (n=272) newly diagnosed dysglycemics and a further 345 normoglycemics were recruited following confirmation of glycemic status by HbA1c, to enable ROC analysis. Apretested questionnaire and the International physical activity questionnaire validated for Sri Lanka were used to generate variables for the risk score.Results:A risk score for dysglycemia with a sensitivity of 87% and specificity of 87% and AUC of 0.941 was developed with two common symptoms of dysglycaemia, history of recent increase in frequency of passing urine and recent reduction in vision, one common food related practice, inability to resist sugary food and one indicator of sedentary behavior, TV viewing time and a single anthropometric measurement, waist circumference.Conclusions: A tool to identify prediabetesis currently unavailable and this new tool fills this gap. Further, the tool is designed to include women with previously undiagnosed diabetes mellitus. Inclusion of lifestyle parameters having a known association with dysglycemia increased the strength of the tool. Early identification will ensure targeting of interventions at the point of maximum effect.

Valor de corte del índice de conicidad como predictor independiente de disglucemias / Cut-off value of the conicity index as an independent predictor of dysglycemia

RESUMEN Introducción: En Cuba no existe consenso acerca del valor del índice de conicidad que debe ser considerado de riesgo para identificar disglucemias. Objetivos: Determinar el punto de corte del índice de conicidad como predictor de disglucemia en ambos sexos. Métodos: Estudio descriptivo transversal con 975 personas (523 mujeres y 452 hombres), que asistieron a consulta externa del Instituto Nacional de Endocrinología por sospecha de diabetes mellitus entre abril de 2008 y abril de 2013. Se les realizó interrogatorio, examen físico y estudios complementarios (prueba de tolerancia oral a la glucosa, insulinemia en ayunas, lípidos y ácido úrico). Se utilizó para el procesamiento estadístico el coeficiente de correlación de Pearson, análisis de regresión logística y el análisis de curvas Receiver Operator Characteristic. Resultados: En el sexo femenino se observó una correlación directamente proporcional y significativa entre el índice de conicidad y las variables glucemia en ayunas y a las 2 h, insulinemia en ayunas, colesterol, triglicéridos, ácido úrico y el índice "homeostasis model assessment of insulin resistance". En el sexo masculino se observó una correlacióndirectamente proporcional y significativa entre el índice de conicidad y las variables estudiadas, excepto con los triglicéridos. El índice de conicidad tuvo su mayor poder predictor de disglucemia con un punto de corte de 1,18 para las mujeres y 1,20 en hombres. Conclusiones: El punto de corte óptimo del índice de conicidad como predictor de disglucemia fue de 1,18 para las mujeres y 1,20 para los hombres; es decir que tuvo un buen poder predictivo de disglucemias en el sexo femenino, no así en el masculino(AU)

ABSTRACT Introduction: In Cuba, there is no consensus about the value of the conicity index that should be considered as risk to identify dysglycemia. Objective: To determine the cut-off point of conicity index as a predictor of dysglycemia in both sexes. Methods: Cross-sectional descriptive study was conducted with 975 people (523 women and 452 men), who attended an outpatient consultation at the National Endocrinology Institute for suspected diabetes mellitus from April 2008 to April 2013. Interrogation, physical examination and complementary studies (oral glucose tolerance test, fasting insulinemia, lipids and uric acid) were performed. Pearson's correlation coefficient, logistic regression analysis and Receiver Operator Characteristic curve analysis were used for statistical processing. Results: In the female subjects, a directly proportional and significant correlation was observed between the conicity index and the fasting blood glucose variables and at 2 h, fasting insulinemia, cholesterol, triglycerides, uric acid and the index homeostasis model assessment of insulin resistance. In the male subjects, a directly proportional and significant correlation was observed between the conicity index and the variables studied, except with triglycerides. The conicity index had its highest predictive power of dysglycemia with a cut-off point of 1.18 in women and 1.20 in men. Conclusions: The optimal cut-off point of conicity index as a predictor of dysglycemia was 1.18 for women and 1.20 for men; that is to say, it was a good predictor of dysglycemias in the female subjects, but not so for male subjects(AU)

Diabetes Mellitus, Lifestyle and Nutrition in Urban Women: Need for Baseline Knowledge, Attitudes and Practices Guided Programs

Introduction: Fundamental to the success of preventive measures in diabetes mellitus, is disease-related knowledge, attitudes, and practices (KAP). We aimed to assess KAP regarding type 2 diabetes mellitus (T2DM), nutrition and lifestyle in a community-based population of newly diagnosed dysglycemic and normoglycemic women, unaware of their glycemic status at the time of data collection. Methods: Women (2800) aged 30-45 years were screened for dysglycemia using cluster sampling from the Colombo Municipal Council area. All 272 dysglycemic detected through screening and 345 normoglycemic randomly selected from the same screened sample were enrolled. All women were unaware of their glycemic status. The sampling strategy aimed to include adequate numbers of women with altered glycemic status who were unaware of their status at the time of the study. A validated and pretested intervieweradministered questionnaire was used and analyzed using Chi-square test and student’s t-test. Results: KAP on T2DM, nutrition and a healthy lifestyle were poor, particularly knowledge on prediabetes. Some aspects of lifestyle modification were known. Women with a family history compared to those without, had better knowledge (p<0.001) and attitudes (p<0.05), but lower practice scores (p<0.05). Majority of women who found it difficult to resist foods high in fat and sugar, ate while watching television, and a higher proportion of them had a family history (p<0.001). Conclusion: Poor food-related practices observed among those with a family history, despite better knowledge and attitudes indicate a need for targeted intervention. The specific KAP related aspects identified here, can direct future intervention strategies.

Utilidad del índice cintura/cadera en la detección del riesgo cardiometabólico en individuos sobrepesos y obesos / Usefulness of the waist/hip index in the detection of cardiometabolic risk in overweight and obese individuals

Introducción: el índice cintura/cadera se presenta como un elemento más de la valoración clínica de la obesidad y sus consecuencias. Objetivo: describir la utilidad del empleo del índice cintura/cadera en la detección del riesgo cardiometabólico. Métodos: se utilizó Google Académico como motor de búsqueda y se obtuvo un total de 97 artículos, de los cuales 61 fueron referenciados por cumplir con el objetivo enunciado. Resultados: la obesidad se comporta como una enfermedad multifactorial, de evolución crónica, con importantes consecuencias para la salud. El incremento del tejido adiposo abdominal, propicia una mayor síntesis y liberación de adipoquinas y otras sustancias, que pueden deteriorar el metabolismo lipídico y glucídico a través del aumento de la resistencia a la insulina, e incrementan el riesgo cardiovascular. El índice cintura/cadera evalúa de forma indirecta la grasa abdominal. Es un indicador poco costoso, sencillo de aplicar y fácil de interpretar en los 3 niveles de atención de salud de nuestro país. Se debe determinar su punto de corte para cada zona geográfica, ya que este puede variar de acuerdo con la entidad nosológica que estemos investigando y la muestra de pacientes estudiados, pues varía con el sexo y las características étnicas. Su empleo ayuda a predecir el riesgo cardiometabólico y de mortalidad en las personas estudiadas. Conclusiones: el índice cintura/cadera es útil en la predicción del riesgo cardiometabólico. Su correcto empleo mejoraría la calidad de los servicios en los 3 niveles de atención de salud en nuestro país(AU)

Introduction: waist/hip index is presented as another element of the clinical assessment of obesity and its consequences. Objective: to describe the usefulness of waist / hip index in the detection of cardiometabolic risk. Methods: Google Scholar was used as a search engine and a total of 97 articles were obtained, of which 61 were referenced for fulfilling the stated objective. Results: obesity behaves like a multifactorial disease of chronic evolution, with important consequences for health. The increase in abdominal adipose tissue promotes greater synthesis and release of adipokines and other substances, which can impair lipid and carbohydrate metabolism through increased insulin resistance, and increase cardiovascular risk. Waist/hip index evaluates abdominal fat indirectly. It is an inexpensive indicator, easy to apply and easy to interpret in the 3 levels of health care in our country. Its cut-off point must be determined for each geographical area, since this may vary according to the nosological entity we are investigating and the sample of patients studied, as it varies with sex and ethnic characteristics. Its use helps to predict cardiometabolic risk and mortality in the people studied. Conclusions: Waist/hip index is useful in the prediction of cardiometabolic risk. Its correct use would improve the quality of services in the 3 levels of health care in our country(AU)

Pattern of dysglycemia among Nigerian adult patients with vitiligo: a 10-year retrospective study

Background: The prevalence of dysglycemia among adult patients with vitiligo is higher than the general population. However, data is scarce in our region regarding this hypothesis. This study was to define the pattern of dysglycemia in adult Nigerian patients with vitiligo.Methods: The study was conducted retrospectively among vitiligo patients who visited the University of Port Harcourt Teaching Hospital between 1st January 2007 and 31st December 2016. The laboratory characteristics of this patients were evaluated. Data collected irrespective of vitiligo variant were age, sex, and fasting plasma glucose concentrations. Shapiro-Wilk test, descriptive statistics, chi-square test, Fisher抯 exact test, and two-sample t-test were used for analysis. The level of p < 0.05 was considered statistically significant.Results: There were a total of 160 vitiligo patients consisting of 55 (34.4%) males and 105 (65.6%) females. The overall patients mean age was 35�9 years (range 19 -61 years). The mean fasting plasma glucose concentration was 5.3�1mmol/l. Impaired fasting plasma glucose was detected in 41(26.6%) subjects with female dominance (female 61.0% versus male 39.0%). Diabetes mellitus was documented in 6 (3.8%) subjects with no sex difference (female 50% versus male 50%).Conclusions: Dysglycemia is frequent in vitiligo patients. Screening for dysglycemia should be incorporated into the management protocol of patients with vitiligo.

A survey of dysglycemia in middle-aged and elderly people in Chongming district of Shanghai / 中华内分泌代谢杂志

Objective To investigate the status of dysglycemia in middle-aged and elderly people in Chongming district of Shanghai. Methods In this cross-sectional study, 10060 permanent residents in Chongming district of Shanghai were surveyed by a random cluster sampling method, with 9913 subjects aged from 40 to 70 years old. Results Of 9913 subjects, 3218 ( 32. 46％) were male with an age of ( 57. 67 ± 7. 54 ) years and 6695 (67.54％) were female with an age of (55.37 ± 7.82) years. The prevalences of diabetes mellitus (DM), impaired fasting blood glucose (IFG), impaired glucose tolerance (IGT), and IFG+IGT were 25.57％(2535/9913), 9.27％(919/9913), 15.90％ (1576/9913), and 9.32％ (924/9913), with the prevalences of pre-diabetes mellitus (PreDM) 34.49％(3419/9913) and dysglycemia 60.06％(5954/9913). IGT was the main form of PreDM in this survey, accounting for 46.1％. The prevalences of IFG, IFG+IGT, and DM in male were higher than those of female ( all P<0.05) while the prevalence of IGT was lower in male than that in female ( P<0.05) . The prevalences of IFG+IGT and DM were increased with age ( P<0.05) , but the prevalences of IFG and IGT were not significantly associated with age ( P>0.05) . The prevalences of IFG, IFG+IGT, and DM were decreased with elevated educational levels ( all P<0.05). The awareness rate of diabetes in this survey was only 38.9％(985/2535), without gender difference. The awareness rate of diabetes was increased with age. Different educational levels had different levels of awareness, and subjects with college or higher education levels showed higher awareness rate compared with those with junior college (P<0.05). Among the patients diagnosed as DM, the control rate of HbA1C<7.0％ was 49.0％(483/985),that of fasting blood glucose was 29.8％(294/985), that of non-fasting glucose was 25.0％(246/985), the proportion of fasting and non-fasting glucose under control was 18.3％(180/985), and the proportion of patients with all controlled fasting, non-fasting glucose and HbA1C<7.0％was only 17.1％(168/985). There was no statistical difference in the control rate of blood glucose between men and women (P>0.05).The control rate of blood glucose was decreased with age (P<0.05), and decreased with the increased cultural level(P<0.05).Among the newly-diagnosed diabetic patients, 322 (20.8％) showed the elevation of isolated fasting blood glucose, 609 (39.3％) showed the elevation of isolated postprandial 2 h blood glucose, and 619 (39.9％) showed the elevations of both fasting and postprandial 2 h blood glucose. Conclusion The prevalence of dysglycemia in middle-aged and elderly people in Chongming district of Shanghai is quite high, with low awareness rate of diabetes. The blood glucose control of diabetic patients in Chongqing is far from being satisfied.

Utilidad de una escala de riesgo para identificar pacientes con disglucemia / Utility of a risk scale to identify patients with dysglycemia

Introducción: la prevalencia de diabetes y prediabetes ha ido en aumento a nivel global y en Cuba. Para identificar individuos en riesgo de disglucemia se han desarrollado varias escalas. Objetivo: evaluar el desempeño de la escala de Bang y otros, para identificar individuos con disglucemia, en una población cubana laboralmente activa. Métodos: se realizó un estudio transversal en 2 902 pacientes, fueron clasificados en portadores o no de disglucemia, a través de las pruebas de glucemia en ayunas, de tolerancia a la glucosa y hemoglobina glucosilada. Se determinó la frecuencia de factores de riesgo de diabetes mellitus tipo 2 comprendidos en la escala de Bang y otros, y en el proceder enfocado en factores de riesgo de American Diabetes Association. Se determinó sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo y Odds Ratio de ambas estrategias. En ambos se calculó el área bajo la curva operativa del receptor. Resultados: se encontró relación entre cada uno de los factores de riesgo previstos en ambos procederes con el diagnóstico de disglucemia. Se encontró sensibilidad de 96,5 por ciento y 79,9 por ciento; especificidad de 20,9 por ciento y 59,1 por ciento; valor predictivo positivo de 10,7 por ciento y 16,1 por ciento; valor predictivo negativo de 98,4 por ciento y 96,8 por ciento; OR de 7,33 y 6,76 y área bajo la curva 0,77 y 0,79 para la escala de Bang y otros, y el procedimiento enfocado en factores de riesgo, respectivamente. Conclusiones: ambos procederes identificaron de forma aceptable el grupo de pacientes con disglucemia(AU)

Introduction: The prevalence of diabetes and prediabetes has been increasing globally and also in Cuba. Several scales have been developed to identify individuals at risk for dysglycemia. Objective: To evaluate the performance of the Bang et al. scale to identify individuals with dysglycemia in a Cuban labor-active population. Methods: A cross-sectional study was carried out on 2 902 patients, classified as having or not suffering from dysglycemia, through fasting glycemia, glucose tolerance test and glycosylated hemoglobin. The frequencies of risk factors for type 2 diabetes mellitus included in the Bang et al. scale and in the risk factor approach of the American Diabetes Association were determined. Sensitivity, specificity, positive predictive value, negative predictive value and Odds Ratio of both strategies were determined. In both, the area under the receiver operating curve was calculated. Results: A relationship was found between each of the predicted risk factors in both procedures with the diagnosis of dysglycemia. Sensitivity was 96.5 percent and 79.9 percent; Specificity of 20.9 percent and 59.1 percent; Positive predictive value of 10.7 percent and 16.1 percent; Negative predictive value of 98.4 percent and 96.8 percent; OR of 7.33 and 6.76 and area under the curve 0.77 and 0.79 for the scale of Bang et al. and the procedure focused on risk factors respectively. Conclusions: Both procedures identified in an acceptable manner the group of patients with dysglycemia(AU)

Índice cintura/talla y su utilidad para detectar riesgo cardiovascular y metabólico / Waist-to-height ratio and its usefulness in detection of the cardiovascular and metabolic risk

Introducción: El exceso de peso se relaciona con condiciones que afectan la salud y la calidad de vida. La ubicación o distribución de la grasa corporal reviste especial interés desde el punto de vista clínico, y varía según sea difusa o localizada, básicamente en el abdomen.Objetivo: describir, en nuestros pacientes, la utilidad de índice cintura/talla en la detección de riesgo cardiovascular y metabólico.Desarrollo: un aumento clínicamente visible de la grasa abdominal y/o visceral obliga a realizar la búsqueda activa de algunos trastornos bioquímicos y clínicos, que se pueden ver como consecuencia de la presencia de obesidad central, la cual puede incrementar el riesgo cardiovascular y metabólico. El índice cintura/talla representa una correlación relativamente simple, útil y no invasiva, para ser aplicado en individuos vulnerables, y es una alternativa bastante utilizada en estudios poblacionales sobre obesidad y distribución regional de la grasa, teniendo en cuenta su eficacia para detectar riesgo cardiometabólico. La circunferencia de la cintura debe estar en menos de la mitad de la talla, de ahí que si es mayor de 0,5, es diagnóstica de obesidad abdominal, cifras mayores han mostrado tener una elevada correlación con el porcentaje de masa grasa corporal, y algunos profesionales lo reconocen como el mejor predictor de riesgo en pacientes con síndrome metabólico, equiparable al índice de masa corporal en la predicción de diabetes mellitus tipo 2, según algunos autores.Consideraciones finales: el índice cintura/talla es una de las correlaciones antropométricas de utilidad para detectar riesgo cardiovascular y metabólico(AU)

Introduction: Excessive weight is related to conditions affecting health and quality of life. Location or distribution of body fat arouses special interest from the clinical viewpoint and varies whether it is diffuse or localized, basically in the abdomen.Objective: to describe in our patients the usefulness of the waist-to-height ratio in the detection of the cardiovascular and metabolic risk.Development: clinically visible increase of the abdominal and/or visceral fat points to the active search of some biochemical and clinical disorders that may derive from the presence of central obesity which can in turn raise the cardiovascular and metabolic risk. The waist-to-height ratio represents a relatively simple, useful and non-invasive correlation index to be applied in vulnerable individuals. It is also a pretty used alternative in population-based studies on obesity and the regional distribution of fat, taking into account its efficacy for detection of the cardiometabolic risk. The waist circumference should measure less than the half of height, so if it is over 0.5, it indicates abdominal obesity. Higher figures have also shown great correlation with the percentage of body fat mass and some professionals admit that it is the best risk forecast in patients with metabolic syndrome. According to some authors, the waist circumference is comparable to the body mass index in type 2 diabetes mellitus prediction.Conclusions: the waist-to-height ratio is one of the useful anthropometric correlations to detect the cardiovascular and metabolic risk(AU)

Clinical significant of predicting the risk of dysglycemia and dyslipidemia based on body mass index,waist circumference and waist-to-hip ratio / 中国综合临床

Objective To investigate the clinical significant and the difference of predicting the risk of dysglycemia and dyslipidemia by body mass index (BMI),waist circumference (WC) and waist-to-hip ratio (WHR) in order to look for the best predicting index.Methods Five thousand and thirty residents were participated to this study who were from Jinshan New Area and nearby of Jinshan,Shanghai,including 2004 males and 3026 females.They were divided into obesity group and non-obesity group based on the index of BMI,WC and WHR respectively.The ROC was made based on the above indies in different gender groups.Results The ROC area of BMI was the biggest with 0.641 (P ＜0.05) for male and 0.617(P ＜0.05) for female.The cut off value was 24.67 or 23.88 based on the male or the female.The same trend was seen in terms of WC with 88.5 cm for the male and 84.5 cm for the female.The small cut off value was seen in terms of WHR and there was no significant between male and female.Among male people,the cut off values was 26.01 in terms of BMI and 88.5 cm in terms of WC,0.89 cm in terms of WHR.Among the female people,there was the less predicting significant in terms of WC or WHR.The area under the curve had no significant differences,and the BMI predicted abnormal blood glucose of no value,the area under the curve is only 0.513 (P ＞ 0.05).Conclusion BMI is proved the best predictor for the risk of dyslipidemia.There are significant among BMI,WC and WHR in terms of predicting dysglycemia in different gender.BMI is proved without significant regarding of predicting dysglycemia in females.

Predictors of restenosis after percutaneous coronary intervention using bare-metal stents: a comparison between patients with and without dysglycemia

The objective of this study was to identify intravascular ultrasound (IVUS), angiographic and metabolic parameters related to restenosis in patients with dysglycemia. Seventy consecutive patients (77 lesions) selected according to inclusion and exclusion criteria were evaluated by the oral glucose tolerance test and the determination of insulinemia after a successful percutaneous coronary intervention (PCI) with a bare-metal stent. The degree of insulin resistance was calculated by the homeostasis model assessment of insulin resistance (HOMA-IR). Six-month IVUS and angiogram follow-up were performed. Thirty-nine patients (55.7 percent) had dysglycemia. The restenosis rate in the dysglycemic group was 37.2 vs 23.5 percent in the euglycemic group (P = 0.299). The predictors of restenosis using bivariate analysis were reference vessel diameter (RVD): £2.93 mm (RR = 0.54; 95 percentCI = 0.05-0.78; P = 0.048), stent area (SA): <8.91 mm² (RR = 0.66; 95 percentCI = 0.24-0.85; P = 0.006), stent volume (SV): <119.75 mm³ (RR = 0.74; 95 percentCI = 0.38-0.89; P = 0.0005), HOMA-IR: >2.063 (RR = 0.44; 95 percentCI = 0.14-0.64; P = 0.027), and fasting plasma glucose (FPG): ≤108.8 mg/dL (RR = 0.53; 95 percentCI = 0.13-0.75; P = 0.046). SV was an independent predictor of restenosis by multivariable analysis. Dysglycemia is a common clinical condition in patients submitted to PCI. The degree of insulin resistance, FPG, RVD, SA, and SV were correlated with restenosis. SV was inversely correlated with an independent predictor of restenosis in patients treated with a bare-metal stent.
