Influence of circadian blood pressure profile on endothelial function in patients with and without arterial hypertension.

Little is known about the relationship between the circadian BP rhythm and endothelial function in patients with essential hypertension. Consequently, we have hypothesized, that hypertensive patients with non-dipper circadian BP profile have more deteriorated endothelial function, than those with dipper BP profile. 57 untreated hypertensive patients and 17 normotensive controls were undergone to the anthropometrical measurements, physical examinations, review of their medical histories, 24-hour ABPM and vascular doppler-echography with high resolution ultrasound.

Reproducibility and diagnostic value of E100 event recorder for patients with complains on heart arrhythmias and no changes on multiple routine ECGs and 24-hour holter monitoring.

Aim of the study was to assess reproducibility and diagnostic value of E100 event recorder for patients with complains on heart arrhythmias and no abnormalities on multiple routine ECGs and/or 24-hour Holter ECG monitoring and the second one, an assessment of adherence and attitude of patients to the E100 event recorder, dependent on the results of self- assessment questionnaires. 24 patients with complains on heart arrhythmias were included in the study. All the patients were provided with the REKA E100 event monitors for 5 ± 2 days and self-assessment questionnaires to assess level of adherence and attitude of patients to the E100 event recorder.
