Echocardiographic Findings and NT-proBNP Level in Type-2 Diabetic Patients With and Without Ischemic Heart Disease

Description
Summary:The aim of this study was to determine whether there are differences in echocardiographic findings or in the level of a biochemical marker (ie, N-terminal probrain natriuretic peptide [NT-proBNP]) between controls and type-2 diabetic patients with or without ischemic heart disease. Echocardiography was used to assess left ventricular function and morphology. In addition, the plasma NT-proBNP concentration was measured. The prevalence of diastolic dysfunction was greater in diabetics without ischemic heart disease than in controls (88% vs 74%, respectively; P<.001) and the NTproBNP concentration was higher (350.6 [197.8] vs 281.7 [190.4] fmol/mL; P<.001). Diabetics with ischemic heart disease had a higher NT-proBNP concentration than those without (720.4 [278.1] vs 350.6 [197.8] fmol/mL, respectively; P<.001). An NT-proBNP concentration >490 fmol/mL had a sensitivity of 84% and a specificity of 75% for detecting ischemic heart disease in diabetics. El objetivo de este trabajo es analizar posibles diferencias ecocardiográficas y bioquímicas (NT-proBNP) entre controles y pacientes diabéticos tipo 2 sin cardiopatía isquémica y con ella. El estudio ecocardiográfico comprendió la forma y la función ventricular izquierda. Además se determinaron las concentraciones plasmáticas de NT-proBNP. Los diabéticos sin cardiopatía isquémica presentaron mayor prevalencia de disfunción diastólica (el 88 frente al 74%; p < 0,001) y mayor concentración de NT-proBNP (350,6 ± 197,8 frente a 281,7 ± 190,4 fmol/ml; p < 0,001) que los controles. Los diabéticos con cardiopatía isquémica mostraron concentraciones de NT-proBNP muy superiores a las de los diabéticos sin cardiopatía isquémica (720,4 ± 278,1 frente a 350,6 ± 197,8 fmol/ml respectivamente; p < 0,001). Una concentración de NT-proBNP > 490 fmol/ml tuvo el 84% de sensibilidad y el 75% de especificidad para detectar cardiopatía isquémica en pacientes diabéticos.
