Cardiovascular control in experimental diabetes

Abstract: Several studies have reported impairment in cardiovascular function and control in diabetes. The studies cited in this review were carried out from a few days up to 3 months after streptozotocin administration and were concerned with the control of the circulation. We observed that early changes (5 days) in blood pressure control by different peripheral receptors were maintained for several months. Moreover, the impairment of reflex responses observed after baroreceptor and chemoreceptor stimulation was probab… Show more

“…Primary changes are observed (around 5 days) in blood pressure controlled by different receptors peripherals that are kept for several months after the induction of diabetes. One of the different mechanisms of cardiovascular control is the activation of cardiopulmonary reflex for a stimulant found in different structures of the chest, including atrium, ventricle, veins, and pulmonary parenchyma, which represents an important source of information on changes in volume and blood pressure of region cardiopulmonary 14 .…”

“…A number of studies have reported that diabetes mellitus (DM) leads to autonomic neuropathic dysfunctions, including impairment of the baroreflex control of heart rate (HR) in both diabetic patients and chemically induced diabetic rats [2,3] . Impairment of the baroreflex sensitivity (BRS) underlying the diabetic state was closely related to lifethreatening arrhythmias, heart failure and sudden death [4,5] .…”

“…Esses animais apresentam muitas alterações semelhantes às observadas em humanos com DM tipo 1, tais como hiperglicemia, deficiência na secreção de insulina, glicosúria, poliúria, perda de peso, neuropatia, nefropatia e cardiopatia (36,37). Em nosso grupo, temos utilizado este modelo na busca da melhor compreensão de alterações do controle autonômico do sistema cardiovascular.…”

“…Em nosso grupo, temos utilizado este modelo na busca da melhor compreensão de alterações do controle autonômico do sistema cardiovascular. Estudos de nosso laboratório mostraram redução da pressão arterial (PA) e da freqüência cardíaca de 5 até 80 dias após a indução do DM (37)(38)(39)(40). Os mecanismos determinantes destas alterações ainda não estão perfeitamente esclarecidos, mas existem evidências consistentes do envolvimento de alterações na freqüência cardíaca intrínseca, no tônus vagal e no controle reflexo cardiovascular (barorreflexo e quimiorreflexo) neste prejuízo cardiovascular (37,41).…”
