Nowadays the term "heart-vessels failure" does not exist.

Aim
To study the kinetics and hemodynamics of arteries in the patients with heart failure with different ejection fraction.

Materials and methods
In our investigation we included 74 patients with heart failure with preserved ejection fraction more than 55% (44 were men and 30 women). Mediana age – 71,3 years old. In the control group we included 52 practically healthy people without cardiac and vessels pathologies.
We divided patients into two groups (I and II) in accordance to the presence of clinical manifestations of heart failure in them. Group I - with clinical symptoms of heart failure (32), group II –without heart failure symptoms (42).
We paid attention to the symptoms of heart failure, myocardial infarction, cardiomyopathies, valves defects, operations on heart in anamnesis. We performed 24-hours ECG monitoring, general blood analysis, biochemical blood analysis (lipids, electrolytes, urine, creatinine, bilirubin, potassium, glucose, NT-proBNP), transthoracic echocardiography, ultrasound doppler of brachiocephalic arteries, abdominal aorta branches, lower extremities arteries, renal arteries, chest radiography, ultrasound investigation of B-lines. If prescribed we performed stress echocardiography, transesophageal echocardiography, coronary angiography, renal arteries angiography, pancerebral angiography, magnet tomography of heart. All patients were registered sphygmography of main arteries: a.carotis communis, ulnaris, radialis, a.tibialis posterior. We analyzed the regular contractions in each type of arteries. The main parameters main arteries kinetics using sphygmography we calculated in automatic mode: speed, acceleration, power, work in period of prevalence of inflow over outflow and in period of prevalence of outflow over inflow.

Results
We analysed the main parameters of arteries kinetics and hemodynamics in each group of patients as well as in control group. We observed the effects:
1)In group II the parameters of arteries kinetics were higher than in group I. It indicates the active propulsive work of arteries in spreading the stroke volume of the heart.
2)In group I the parameters of arteries kinetics were lower than in control group. It indicates that propulsive function of the arteries is reduced in patients with heart failure.

Conclusion
Arterial vessels are active, full-fledged participant in cardiovascular system. Vessels make an active work in blood movement from the heart to the distal parts and tissues. The clinical manifestations of heart failure are determined not only the heart function but also the function of arteries that is needed to be examined. In patients with preserved ejection fraction we can observe the symptoms of heart failure, the function abilities of arteries are reduced. The term "heart-vessels failure" should be used and applied not only to the heart but also to the arteries function in their coupling with heart. Abstract Figure.
