The notion of finite-time Lyapunov exponent averaged over initial conditions is used for characterizing transient chaos observed in one-dimensional maps. A model of its dependence on time is verified by comparing theoretically predicted values with those obtained numerically. Finally, the same model is used for estimating duration of transient chaos(More)
AIMS The currently available data indicate a drug-drug interaction between morphine and oral P2Y12 receptor inhibitors, when administered together. The aim of this trial was to assess the influence of infused morphine on pharmacokinetics and pharmacodynamics of ticagrelor and its active metabolite (AR-C124910XX) in patients with acute myocardial infarction.(More)
Over recent years, a considerable increase in the popularity of cryostimulation and whole body cryotherapy (WBC) procedures has occurred both among healthy individuals and in various groups of patients, including those with primary untreated hypertension. The aim of this study was to compare the effects of WBC on the functional parameters of cardiovascular(More)
Oral administration of crushed ticagrelor tablets turned out to be an efficacious method that improves its pharmacokinetics and pharmacodynamics. This strategy, however, is unlikely to eliminate the drug-drug interaction in patients receiving intravenous morphine, as the impairment of the P2Y12 inhibitor absorption related to decreased propulsive motility(More)
BACKGROUND The purpose of our experiment was to determine whether laser stimulation can improve microcirculation in the posterior regions of the brain in patients with vertebrobasilar insufficiency (VBI). MATERIAL/METHODS We studied 25 patients (20 female, 5 male, mean age 64) diagnosed with chronic VBI. All were evaluated using the De Klyn test, followed(More)
INTRODUCTION The most common classification of acute myocardial infarction (AMI) is based on electrocardiographic findings and distinguishes ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI). Both types of AMI differ concerning their epidemiology, clinical approach and early outcomes. Ticagrelor is a P2Y12(More)
This paper presents an application of Approximate Entropy (ApEn) and Sample Entropy (SampEn) in the analysis of heart rhythm, blood pressure and stroke volume for the diagnosis of vasovagal syndrome. The analyzed biosignals were recorded during positive passive tilt tests—HUTT(+). Signal changes and their entropy were compared in three main phases of the(More)
BACKGROUND Studies published during the last decade seem to indicate red blood cell parameters as inexpensive, rapidly available, and simple tools for the assessment of prognosis in patients with chronic heart failure (CHF). AIM To evaluate the prognostic value of red cell parameters determined in a routine blood count in patients with CHF. METHODS The(More)
BACKGROUND Melanoma cell adhesion molecule (MCAM) is a marker of endothelial damage. MCAM diagnostic and prognostic value was assessed in chronic heart failure (CHF). MATERIALS & METHODS 130 CHF patients and 32 controls were included in the study. Telephone follow-up lasted one year. End points were: death from all causes, and hospitalization with CHF(More)
In this paper we present an example of application of Approximate Entropy and Sample Entropy in analysis of vasovagal syndrome. In our research we conducted an analysis based on three types of data: RRI (RR intervals), SBP (systolic blood pressure) and TPR (total peripheral resistance), which were measured simultaneously with the head up tilt table test(More)
