Abstract

Introducción y objetivosLa glucemia al ingreso (GI) es un factor pronóstico conocido en el síndrome coronario agudo (SCA), pero hay poca información acerca del valor de la primera glucemia en ayunas (PGA). Este estudio analiza el valor pronóstico de la PGA en pacientes con SCA comparado con el de la GI.MétodosSe analizó a los 547 pacientes que ingresaron consecutivamente en nuestro centro con el diagnóstico de SCA en el año 2006. Las cifras de GI y PGA fueron estratificadas en tres niveles (< 126, 126-200 y > 200 mg/dl). El objetivo primario del estudio fue el evento combinado de muerte y/o reinfarto durante la hospitalización.ResultadosEl desenlace principal ocurrió en 46 pacientes (25 muertes). Los pacientes de este grupo eran de mayor edad, más frecuentemente diabéticos, fumadores, con infarto de miocardio previo, con superior clase Killip durante el ingreso, con afección de más de un vaso en la coronariografía, con menor fracción de eyección y mayores creatinina al ingreso, GI y PGA. En el análisis multivariable ajustado por las variables anteriores, la PGA se mostró como predictor independiente de muerte y/o reinfarto (126-200 mg/dl, odds ratio [OR] = 5,26; intervalo de confianza [IC] del 95%, 1,09-25,45; > 200 mg/dl, OR = 6,66; IC del 95%, 2,05-21,63), no así la GI (126-200 mg/dl, OR = 0,84; IC del 95%, 0,63-1,05; > 200 mg/dl, OR = 1,14; IC del 95%, 0,29-4,51).ConclusionesLa PGA se mostró mejor predictor de eventos adversos (muerte y/o reinfarto) que la GI en pacientes con SCA durante la hospitalización.

Introduction and objectivesThe admission plasma glucose (APG) level is a recognized prognostic factor in patients with acute coronary syndrome (ACS). However, little is known about the prognostic value of the first fasting plasma glucose (FPG) measurement. The aim of this study was to determine the prognostic value of the first FPG measurement relative to that of the APG level in patients with ACS.MethodsThe study involved 547 consecutive patients who were admitted to our center with a diagnosis of ACS in 2006. Patients were divided into three groups according to their first FPG or APG level (i.e., <126 mg/dL, 126-200 mg/dL, or >200 mg/dL). The primary endpoint was the combined outcome of death or reinfarction during hospitalization.ResultsThe primary endpoint was observed in 46 patients, 25 of whom died. Patients in this group were older, were more often diabetics or smokers, more often had had a prior myocardial infarction, were in a higher admission Killip class, showed more than one vessel disease on catheterization, had a lower left ventricular ejection fraction, and had higher admission creatinine, APG, and first FPG levels. Multivariate analysis, adjusted for previously identified factors, revealed that the first FPG level was an independent risk factor for death or reinfarction (126-200 mg/dL, odds ratio [OR]=5.26; 95% confidence interval [CI], 1.09-25.45; >200 mg/dL, OR=6.66; 95% CI, 2.05-21.63), but that the APG level was not (126-200 mg/dL, OR=0.84; 95% CI, 0.63-1.05; >200 mg/dL, OR=1.14; 95% CI, 0.29-4.51).ConclusionsThe first FPG level was found to be a better predictor of an adverse outcome (i.e., death or reinfarction) during hospitalization in ACS patients than the APG level.
