          Abstract

          RESUMEN Introducción: Acumulaciones excesivas de tejido adiposo constituyen una amenaza para la salud cardiometabólica, el estudio en la mujer orientaría mejor sobre su estado metabólico. Objetivo: Identificar asociaciones entre estados de vulnerabilidad cardiometabólica e índices aterogénicos en el posparto a corto plazo. Método: Se realizó un estudio observacional descriptivo, entre enero 2017 y agosto 2018, en 119 mujeres en el posparto a corto plazo, a partir de una población de 773 gestantes de peso adecuado y aparentemente sanas al momento de la captación, clasificadas por su vulnerabilidad cardiometabólica por adiposidad corporal en el Policlínico Chiqui Gómez Lubián, entre enero 2012 y diciembre 2016. Se estudió la asociación de la vulnerabilidad cardiometabólica con los índices aterogénicos: Castelli, Kannel y la relación TG/HDLc. Se aplicó la prueba de Kruskal-Wallis para la comparación de muestras independientes. Resultados: Los índices Castelli (3,37), Kannel (2,02) y TG/HDLc (0,71) tuvieron valores medios más bajos en las mujeres sin vulnerabilidad. Los índices Castelli (4,20) y Kannel (2,69) mostraron valores más elevados en mujeres con vulnerabilidad global extrema por adiposidad general alta y central alta. El índice TG/HDLc (1,18) tuvo los valores más elevados en mujeres con vulnerabilidad global por adiposidad general intermedia y central alta. Conclusiones: Los valores de los índices aterogénicos estudiados en el posparto a corto plazo estuvieron asociados con la vulnerabilidad cardiometabólica, con cifras más elevadas en mujeres con adiposidad general intermedia y alta, y adiposidad central alta. La vulnerabilidad cardiometabólica por adiposidad corporal en el posparto a corto plazo, puede alertar sobre alteraciones metabólicas aterogénicas, como riesgo cardiovascular.

          ABSTRACT Introduction: Excessive accumulations of adipose tissue are a threat to cardiometabolic health; their assessment in women would better inform about their metabolic state. Objective: To identify associations between cardiometabolic vulnerability states and atherogenic indices in the short-term postpartum period. Method: A descriptive observational study was conducted from January 2017 to August 2018 on 119 women in short-term postpartum. The study population consisted of 773 pregnant women with adequate weight and apparently healthy at the time of recruitment, who were classified based on their cardiometabolic vulnerability due to body adiposity at the Policlínico Chiqui Gómez Lubián, between January 2012 and December 2016. The association of cardiometabolic vulnerability with the atherogenic indices was studied: Castelli, Kannel and the TG/HDLc ratio. The Kruskal-Wallis test was applied to compare independent samples. Results: The Castelli (3.37), Kannel (2.02) and TG/HDL (0.71) indices showed lower mean values in women without vulnerability. The Castelli (4.20) and Kannel (2.69) indices showed higher values in women with extreme global vulnerability due to high overall adiposity and high central adiposity. The TG/HDLc index (1.18) reached the highest values in women with global vulnerability due to intermediate and high central overall adiposity. Conclusions: The values of the atherogenic indices studied in the short-term postpartum period were associated with cardiometabolic vulnerability, with higher figures in women with intermediate and high general adiposity, and high central adiposity. Cardiometabolic vulnerability due to body adiposity in the short-term postpartum period may alert about atherogenic metabolic disorders, such as cardiovascular risk.

          Is there a simple way to identify insulin-resistant individuals at increased risk of cardiovascular disease?

          The goal of this study was to evaluate the ability of various routine measures of lipoprotein metabolism to identify patients who were insulin resistant and dyslipidemic, and therefore, at increased risk of cardiovascular disease. For this purpose, insulin resistance was quantified by determining the steady-state plasma glucose concentration during the insulin suppression test in 449 apparently healthy patients. The low-density lipoprotein (LDL) particle diameter and subclass phenotype were measured by gradient gel electrophoresis in 1,135 patients. Pearson's correlation coefficients and receiver-operating characteristic curves were used to evaluate measures of lipoprotein metabolism as potential markers of insulin resistance and LDL phenotype. The results indicated that the ratio of the plasma concentrations of triglyceride to high-density lipoprotein cholesterol was the best predictor of insulin resistance and LDL particle diameter. The optimal triglyceride/high-density lipoprotein cholesterol ratio for predicting insulin resistance and LDL phenotype was 3.5 mg/dl; a value that identified insulin-resistant patients with a sensitivity and specificity comparable to the criteria currently proposed to diagnose the metabolic syndrome. The sensitivity and specificity were even greater for identification of patients with small, dense, LDL particles. In conclusion, a plasma triglyceride/high-density lipoprotein cholesterol concentration ratio > or =3.5 provides a simple means of identifying insulin-resistant, dyslipidemic patients who are likely to be at increased risk of cardiovascular disease.

            Relationships of surrogate indexes of insulin resistance with insulin sensitivity assessed by euglycemic hyperinsulinemic clamp and subclinical vascular damage

            Introduction Insulin resistance plays a crucial role in the pathogenesis of type 2 diabetes and cardiovascular disease. The triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, visceral adiposity index (VAI), lipid accumulation product (LAP) and triglycerides × fasting glucose (TyG) index are surrogate measures of insulin sensitivity based on anthropometric and/or biochemical parameters routinely collected in clinical practice. Herein, we compared the relationships of these four surrogate indexes with insulin sensitivity assessed by the gold standard euglycemic hyperinsulinemic clamp technique, and subclinical vascular damage. Research design and methods 631 subjects with different degrees of glucose tolerance underwent euglycemic hyperinsulinemic clamp. The surrogate TG/HDL-C ratio, VAI, LAP and TyG indexes were computed. Pulse pressure and carotid intima-media thickness (IMT) were measured as indicators of subclinical vascular damage. Results All the four surrogate indexes showed a significant correlation with insulin-stimulated glucose disposal in the whole study population. However, only LAP index had a significant association with insulin sensitivity across the different glucose tolerance groups. LAP index showed the highest area under the receiver operating characteristic curve (0.728) to detect individuals with insulin resistance defined as the bottom quartile of insulin-stimulated glucose disposal, followed by TG/HDL-C ratio (0.693), TyG index (0.688) and VAI (0.688). A significant association was found between the four indexes of insulin sensitivity and pulse pressure and IMT. All the four indexes have a similar ability to detect individuals with vascular atherosclerosis defined by IMT>0.9 mm. Conversely, LAP index had the greatest ability to recognize individuals with increased vascular stiffness defined by pulse pressure ≥60 mm Hg. Conclusion Among the surrogate TG/HDL-C ratio, VAI, LAP and TyG indexes of insulin sensitivity, LAP index showed a significant association with insulin-stimulated glucose disposal across the different glucose tolerance categories and the highest ability to detect insulin resistance and subclinical vascular damage.
