Caracterización tisular miocárdica por ultrasonidos y detección de disfunción diastólica por Doppler pulsado: ¿Ãndices precoces de miocardiopatÃa diabética?
Introduction: There is an intrinsec myocardiopaty
related with the diabetes and probably produced for the
increment of collagen in the myocardium. Objective: To
value the paper of the tissular myocardial
characterization by ultrasound and the detection of
diastolic dysfunction by pulsated Doppler as precocious
indexes of diabetic miocardiopaty. Methods:
Transverse, prospective,and controlled study that
analyzed the diastolic function with pulsated Doppler in
60 diabetic patients and a control group of 15 healthy
individuals; all with a normal pressure, with a negative
ergometric test and normal systolic function; 40
presented microvascular complications. The securities of
magnitude of recurrent variation were determined at the
level of the septum and the posterior wall. The
echocardiograms were carried out with the equipment
ALOKA 5500 with a multiband transducer of 2.5 MHZ
using the beta digital handling program (DMS) and the power Doppler in ecocardiografic views . Results:
Reduction of the recurrent variation was obtained in
diabetics with respect to the control group at the level
of the septum 2D (3.4 ±1.3 vs. 4.4 ± 0.4 dB; p <0.003)
and the posterior wall PP2D (3.4 ± 1.3 vs. 6.2 ± 0.4 dB;
p <0.000001). Was found a correlation between the
presence of diastolic dysfunction and the low
magnitudes of ciclic variation (p <0.001). The tissular
characterization was more sensitive to detect precocious
changes of the myocardium in diabetic patients (p
<0.001). Conclusions: The diabetes mellitus is cause of
myocardiopaties that originate very precocious
alterations in the myocardium of these patients; these
changes can be discovered in very early phases by the
pulsated Doppler detecting diastolic dysfunction and the
tissular characterization by ultrasounds. This last one is
more sensitive for the diagnosis of this entity.Fundamento: Existe una miocardiopatÃa relacionada
intrÃnsecamente con la diabetes y probablemente
producida por el incremento de colágeno en el
miocardio. Objetivo: Valorar el papel de la
caracterización tisular miocárdica por ultrasonido y la
detección de disfunción diastólica por Doppler pulsado
como Ãndices precoces de miocardiopatÃa diabética.
Métodos: Estudio transversal, prospectivo, controlado
que analizó la función diastólica con Doppler pulsado en
60 pacientes diabéticos y un grupo control de 15
personas sanas; todos normotensos, con prueba
ergométrica negativa y función sistólica normal; 40
presentaban complicaciones microvasculares. Los valores
de magnitud de variación cÃclica fueron determinados a
nivel del septum y la pared posterior. Los
ecocardiogramas se realizaron con el equipo ALOKA
5500 con un transductor multibanda de 2.5 MHZ
utilizando el programa beta de manejo digital (DMS) y el
Power Doppler en vistas ecocardiográficas Resultados:
Se obtuvo reducción de la variación cÃclica en diabéticos
respecto al grupo control a nivel del septum 2D (3.4
±1.3 vs. 4.4 ± 0.4 dB; p<0.003) y pared posterior PP2D
(3.4 ± 1.3 vs. 6.2 ± 0.4 dB; p< 0.000001). Se encontró
correlación entre presencia de disfunción diastólica y
magnitudes bajas de variación cÃclica (p<0.001). La
caracterización tisular fue más sensible para detectar
cambios precoces del miocardio en pacientes diabéticos
(p<0.001).Conclusiones: La diabetes mellitus es causa
de miocardiopatÃas que originan alteraciones muy precoces en el miocardio de estos pacientes; estos
cambios pueden ser descubiertos en fases muy
tempranas por el Doppler pulsado detectando disfunción
diastólica y la caracterización tisular por ultrasonidos.
Esta última es más sensible para el diagnóstico de dicha
entidad
