[Influence of the arterio-venous fistula on cardiovascular system in patients with particular cardiovascular risk].
In the population of hemodialysis patients the risk of ischemic heart disease and morbidity related to it, is considerably higher than in general population. In the group of elderly hemodialysed patients and in patients with diabetes this risk is even higher Additional risk factors of cardiovascular disease are those specific for renal insufficiency, including the presence of arterio-venous fistula, which is believed to be an independent risk factor for cardiovascular disease through the promotion of hyperkinetic circulation. In the study the impact of the arterio-venous fistula on heart function in Doppler USG in the group of 16 elderly hemodialysis patients (aged 79, 4 +/- 5,4), 10 diabetics with type 2 diabetes (aged 63,2 +/- 10,4) and 7 hemodialysis patients younger and without diabetes was examined. In all patients arterio-venous fistula was created on the forearm from native vessels. The following hemodynamic USG parameters of heart function were assessed: ejection fraction (EF), shortening fraction (FS), stroke volume (SV) and cardiac output (CO). We conclude that impact of native arterio-venous fistula created on forearm on circulation in the group of elderly and diabetic patients is of the same magnitude as in the group of younger, non diabetic patients.
