Resumen en inglés Diabetes mellitus accelerates atherosclerosis. Monitoring arterial condition promises to be an advantage in the detection of any abnormalities. In this study, the characteristics of analysis by photoplethysmogram (PPG) were investigated non-invasively among diabetic patients. An area under the curve (auc-PPG) was compared for two levels of HbA1c, namely HbA1c < 8% (Group 1) and HbA1c > 10% (Group 2). Auc-PPG was found to be significantly higher among diabetic subjects with HbA1c < 8% than among those with HbA1c > 10%. Further analysis was performed to investigate the effect of age on auc-PPG. The mean values of auc-PPG were still significantly higher among diabetic patients with HbA1c < 8% than among those with HbA1c > 10%. These results show that the auc-PPG method could be a parameter in determining the arterial stiffness in relation to the level of HbA1c
Resumen en portugués Diabetes mellitus acelera a aterosclerose. O monitoramento arterial promete ser uma vantagem na detecção de qualquer anormalidade. Investigaram-se as características de análise não invasiva por fotopletismograma (PPB) entre pacientes diabéticos. A área sob o arco (auc-PPG) foi comparada para dois níveis de HbA1c, ou seja, HbA1c < 8% (Grupo 1) e HbA1c > 10% (Grupo 2). Auc-PPG foi significativamente mais alta entre os sujeitos diabéticos com HbA1c < 8% do que entre aqueles com HbA1c > 10%. Investigou-se o efeito da idade sobre auc-PPG. Os valores médios de auc-PPG foram ainda significativamente mais altos entre pacientes diabéticos com HbA1c < 8% do que entre aqueles com HbA1c > 10%. Os resultados mostram que o método auc-PPG poderia ser um parâmetro para determinar a rigidez arterial em relação ao nível de HbA1c
