[Early diagnosis of @entity551 in XXXX ].

@entity1 @entity191 @entity5433 @entity551 @entity65
@entity5433 in @entity191 ( @entity191 ) is common and occurs in 70% of @entity1 . The aim of the study was to evaluate autonomic mechanisms regulating cardiovascular system during tilt up test in @entity191 @entity1 . The examination was performed in 35 @entity1 with @entity191 (26 male and 9 female, mean age 60 +/- 9) and matched with gender and age 35 controls subjects (healthy volunteers, mean age 59 +/- 9). @entity1 were divided into two groups: group I--early stage of disease (n = 20) and group II--advanced stage of the disease (n = 15). The tilt test in @entity191 @entity1 and in the control group lasted 3 minutes. In both groups tilt test was performed with a head-up tilt position of 60 degrees (tilt table Manumed, Netherlands). In both groups 30:15 ratio were lower than in the control group 1.03 +/- 0.08, 0.97 +/- 0.09 v 1.23 +/- 0.1 respectively (p = 0.001). In the second group the heart-rate variability after the tilt test was lower 6.2 +/- 4/min than in the control group 10.2 +/- +/- 1.9/min and group I 8.8 +/- 4/min (p = 0.01). The decrease of the systolic pressure in response to the tilt test was the highest in group II (16 +/- 14 mmHg), in the control group 4 +/- 7 mmHg, in group I 13 +/- 11 mmHg (p = 0.001). @entity551 in @entity191 occurs in 36% of @entity1 in an early stage and in 47% of @entity1 in an advanced stage of the disease. The use of the tilt test enables the early diagnosis of @entity65 in @entity191 .
