Vegetative day-time tonus in patients with chronic heart failure with and without Cheyne Stokes breathing
No full textGesamtdissertationIn der vorgelegten Untersuchung wurde der autonome Tonus bei
herzinsuffizienten Patienten mit und ohne Cheyne Stokes am Tage untersucht.
Hierzu wurden 12 Patienten mit chronischer Herzinsuffizienz und 12
altersentsprechend gesunde Probanden hinsichtlich 14 Parameter in 5
verschiedenen Vergleichsgruppen untersucht. Nachgewiesen werden konnten
Veränderungen der Herzfrequenzvariabilität, Blutdruckvariabilität, der
Barorezeptorsenitivität sowie der Herzperiodendauer der Blutdruckmittelwerte.
Ebenso zeigten Patienten mit einer chronischen Herzinsuffizienz im Vergleich
zu Gesunden eine geringere Barorezeptorsensitivität sowie eine erniedrigte
Herzfrequenzvariabilität. Eine Verschlechterung der Parameter konnte bei
zeitgleichem Vorliegen einer schlafbezogenen Atmungsstörung, insbesondere der
Cheyne Stokes Atmung nachgewiesen werden.In this analysis the parameter of the autonomic balance in daytime of patients
with chronic heart failure with and without cheyne stokes breathing were
examined. Therefor 12 patients with chronic heart failure and 12 healthy
probands apropriate to their age were examined in 5 comparison groups in
reference to 14 parameters. Variances in heart rate variablity, bloodpressure
variability, baroreflexsensitivity, heart rate and blood pressure could be
proved. Comparing patients with heart failure to healthy probands there could
be proved a lower baroreflexsensitivity and heart rate variability within the
patients. There could also be proved that a sleeping disease in addition
especially within cheyne stokes respiration could worsen these parameters
Reversal of ticagrelor-induced arrhythmias and cheyne-stokes respiration with aminophylline infusion
No full textDyspnea and bradyarrhythmias are frequent adverse effects (AEs) of ticagrelor. AEs commonly occur within the first week of therapy, are dose related and usually mild, but sometimes they may cause drug discontinuation. Currently, the exact mechanisms of ticagrelor-related AEs have not been definitively explained. In addition to the prevalent theory of adenosine overload, other reasonable mechanism like a direct central stimulation hypothesis was suggested. We present a case of incessant Cheyne-Stokes respiration associated with heart rate instability in patient with congestive heart failure and non-ST-segment elevation myocardial infarction, supporting the use of aminophylline as a potential reversal agent of ticagrelor-related AEs
Ld-EEG Effective Brain Connectivity in Patients With Cheyne-Stokes Respiration
No full textThe characterization of brain cortical activity in heart-failure patients affected by Cheyne-Stokes Respiration might provide relevant information about the mechanism underlying this pathology. Central autonomic network is gaining increasing attention for its role in the regulation of breathing and cardiac functions. In this scenario, evaluating changes in cortical connectivity associated with Cheyne-Stokes Respiration may be of interest in the study of specific brain-activity related to such disease. Nonetheless, the inter subject variability, the temporal dynamics of Central-Apnea/Hyperpnea cycles and the limitations of clinical setups lead to different methodological challenges. To this aim, we present a framework for the assessment of cortico-cortical interactions from Electroencephalographic signals acquired using low-density caps and block-design paradigms, arising from endogenous triggers. The framework combines ICA-decomposition, unsupervised clustering, MVAR modelling and a permutation-bootstrap strategy for evaluating significant connectivity differences between conditions. A common network, lateralized towards the left hemisphere, was depicted across 8 patients exhibiting Cheyne-Stokes Respiration patterns during acquisitions. Significant differences in connectivity at the group level were observed based on patients' ventilatory condition. Interactions were significantly higher during hyperpnea periods with respect to central apneas and occurred mainly in the delta band. Opposite-sign differences were observed for higher frequencies (i.e. beta, low-gamma)
