%X Se estudiaron 60 pacientes con diabetes mellitus para correlacionar las alteraciones ecocardiogr芍ficas del miocardio, mediante t谷cnica de caracterizaci車n h赤stica (variaci車n c赤clica), con los trastornos de la glucemia y la presencia de complicaciones microvasculares. Se detect車 que exist赤a asociaci車n entre alteraciones de la variaci車n c赤clica y presencia de complicaciones microvasculares (p = 0,003). Se obtuvo una correlaci車n lineal entre valores altos de HbA1 y alteraciones de caracterizaci車n h赤stica al nivel del septum 2D (p<0,001; r = - 0,4), as赤 como con hiperglucemia posprandial 2h (p < 0,01; r = - 0,3) y enayunas (p < 0,04; r = - 0,2). Igualmente, encontramos correlaci車n lineal inversa entre el tiempo de evoluci車n de la enfermedad y los valores de variaci車n c赤clica, tanto para septum 2D (p < 0,003; r = -0,4) y PP2D (p < 0,001; r = - 0,3). Se concluy車 que la caracterizaci車n h赤stica del miocardio permite detectar alteraciones precoces en diab谷ticos complicados con da o microvascular, traducidas por disminuci車n de la variaci車n c赤clica, correlacionadas con descontrol gluc谷mico y mayor tiempo de evoluci車n de la enfermedad. 60 patients with diabetes mellitus were studied to correlate the echocardiographic alterations of the myocardium, by histic characterization technique (cyclical variation), with glycaemia disorders and the presence of microvascular complications. An association between the alterations of cyclical variation and the presence of microvascular complications was found (p = 0.003). It was obtained a lineal correlation between the high values of HbA1 and the histic characterization alterations at the level of the septum 2D (p< 0.001; r = - 0.4), as well as with postprandial hyperglycaemia 2h (p<0.01; r = - 0.3) and under fasting conditions (p<0.04; r = - 0.2). Likewise, it was observed an inverse lineal correlation between the time of evolution of the disease and the values of cyclical variation, both for septum 2D (p<0.003; r = -0.4) and PP2D (p < 0.001; r = - 0.3). It was concluded that the histic characterization of the myocardium allows to detect early alterations in diabetic patients complicated with microvascular damage, expressed by the decrease of the cyclical variation, correlated with glycaemia decontrol and a longer time of evolution of the disease.
