Association of @entity148 with reduced baroreflex cardiac control in XXXX after @entity583 .

@entity1 @entity308 @entity73 @entity4375 @entity148 @entity583
BACKGROUND: Although @entity308 has been associated with increased mortality in @entity1 after @entity583 ( @entity583 ), little is known about the effects of @entity308 on autonomic nervous system control of heart rate. This study evaluated whether @entity308 is associated with @entity73 ( @entity4375 ) in @entity1 with @entity583 . METHODS: Two hundred four hospitalized @entity1 with @entity583 were evaluated 6 +/- 3 (mean +/- SD) days after @entity583 . @entity4375 was assessed using cross-spectral analysis to measure baroreceptor-mediated R-R interval oscillations. @entity308 was determined using the Diagnostic Interview Schedule, and severity of @entity308 symptoms was measured with the Beck @entity308 Inventory. In order to adjust for possible differences in @entity148 , we also measured state @entity148 using the Spielberger State Anxiety Inventory. RESULTS: @entity308 was not significantly related to @entity4375 . However, @entity148 was significantly related to low @entity4375 in multivariate analysis, after the potentially confounding variables of age, blood pressure, and respiratory frequency were controlled for. Comparison of groups with high and low @entity148 (on the basis of a median split of state @entity148 scores) showed that @entity4375 was reduced by approximately 20% in the @entity1 with the higher @entity148 scores (4.7 +/- 3.2 ms/mm Hg vs 5.7 +/- 3.3 ms/mm Hg, P <.05), after adjustment for differences in age, blood pressure, and respiratory frequency. CONCLUSIONS: High levels of @entity148 , but not @entity308 , are associated with reduced vagal control in @entity1 after @entity583 .
