( e loss of elasticity in the blood vesse...)A New System Developed For Studying The Condition Of The Human Arterial System,Health

e loss of elasticity in the blood vessels.

Prevention system:
The system designed by Fernando Silvio Nu?o is currently being employed at the University of Mar de Plata in order to evaluate the arterial system of all employees, who subsequently have a medical check-up by the University’s medical service.

The state of the arterial system, to date, has been evaluated through blood pressure measurement using the traditional armband. But this does not enable one to identify the biological age of the system, only the systolic and diastolic pressures.

The next challenge for this researcher is to evaluate the whole cardiovascular system, i.e. both the heart and the blood vessels. The mathematical tool to this end is there; only the evaluation of the cardiac variables is needed in conjunction with the variables already obtained for the arterial system.

New software:
The PhD outlined an automatic method for registering the values of the variables of the variation curves for the arterial diameters and the development of the corresponding software.

Likewise, with the aim of reducing the number of variables and of locating the most important ones for the observation of the arterial system, Principal Components Analysis and Lineal Multiple Regression mechanisms were applied in order to determine the dependent and independent variables of the system. The initial figure of 50 independent variables was reduced to 7.

Besides, it was confirmed that the 7 selected variables represented exactly the characteristics of the variation curves for the arterial diameters by means of the calculation of multiple correlation coefficients.
