The analysis of anamnesis and the hemodynamic response in tilting patients with recurrent syncope
Journal Title: Archives of Medical Science - Year 2005, Vol 1, Issue 4
Abstract
Introduction: Vasovagal syncope (VVS) constitutes 70% of all unexplained syncope. In this group of patients (pts.) the head-up tilt test (HUTT) is a basic diagnostic method. The aim of the study was the analysis of anamnesis and of noninvasive hemodynamical parameters (heart rate and blood pressure) in tilting patients with recurrent syncope. Material and methods: 170 patients (pts.) with history of recurrent syncope enrolled in the research. The control group comprised 19 healthy volunteers. In all the anamnesis with the specific data of syncope and HUTT in the Westminster protocol prolonged by nitroglycerin provocation were performed. All pts. were divided into the following groups according to the HUTT outcome: positive HUTT (I group) N=129; mean age 50.6±17.8 yrs, 0.37 males; and negative HUTT (II group) N=41; mean age 50.0±18.3 years, 0.56 males. In the multivariate approach the logistic regression analysis was used to identify from anamnesis and noninvasive hemodynamic parameters the most predictive factor of the positive HUTT. Results: The HUTT explained vasovagal origin of syncope in 129 pts. (76%) of the study group. Group I noted a significant increase (p

The estimation of erythropoietin levels in the blood serum and cystic fluid in patients with solitary renal cysts
Introduction: The role of erythropoietin (EPO) in patients with renal cysts remains unclear. Some authors suggest that EPO may be produced in renal cysts (RC). The aim of the study was to answer the question why concent...
