It is the matter of fact that not only our reading audience has significantly expanded recently, but more important, we note an increasing number of physicians among our readers who successfully apply theory in practice. At the same time it should be stated that a problem of medical education becomes acute.

Pioneering technology: breakthrough diagnostics in cardiology
As usual, the Congress of European Society of Cardiology attracted many experts and visitors. 4597 abstracts were presented. It was reported that more than 30000 cardiologists participated there.
The Sonocard experiment purpose was a noninvasive physiological signal recording from sleeping humans. In 2007-2012 the experiment was made by 22 Russian members of 17 missions to the International space station. Of the overall 302 experimental sessions 47 were performed pre, 215 in and 40 after flight.

Hypertrophic cardiomyopathy (HCM) is the commonest inherited cardio-myopathy. Prevalence 1/500 individuals. The disease has variable expressivity and penetrance, which leads to a diverse phenotypical expression. The aim of this review paper is to shed light on management of HCM.

Current status and prospects for e-Cardiology & e-Health development based on materials of the European Congress on e-Cardiology & e-Health, Bern, 29-31 October, 2014
The European Congress on e-Cardiology & e-Health took place in Bern, Switzerland. There were 250 participants from 23 countries and 90 speakers presented papers. The Congress was devoted to the latest advancements in e-Cardiology, e-Health and telemedicine.
In the suggested here linear theory of hydrodynamic instability of the Hagen - Poiseuille flow it is counted the possibility of quasi periodic longitudinal variations, when there is no separation of the longitudinal and radial variables in the description of the disturbances field.

Congenital paroxysmal atrial fibrillation in infants is a rare occurrence requiring a high index of suspicion. The majority have a pre-excitation syndrome which may be concealed. It may be associated with specific structural congenital cardiac lesions. This index case had only paroxysmal atrial tachyarrhythmia with no predisposing condition that subsided spontaneously and is the first case documented in an Afro-Caribbean infant.

This is an overview aimed at a detailed interpretation of the concept of identification of boundaries in each cardiac cycle, and first it is directed to justification of an introduction of new points on an ECG curve, namely, point L as the end of the blood rapid ejection phase and point Z as the moment of reaching energy balance of myocardial muscle contraction determining the ECG isoline.

The effects of long-term microgravity on autonomic regulation of blood circulation in crewmembers of the international space station
The article presents the results of space experiment “Pneumocard”. The investigation involved all 25 Russian members of the ISS crew. The total of 226 sessions were made including 130 aboard the ISS, 50 prior to launch and 46 on return from mission.

A shortcoming common to all existing designs of mechanical cardiac valve prostheses is an increased trombogenicity caused, among other factors, by the lack of hydrodynamic compatibility between the luminal part of the prosthesis and the patterned blood flow. The aim of the study is to design and test our new mechanical aortic valve prosthesis to exclude life-long anticoagulation treatment.
