Abstract
The measurement of pulse wave velocity is a generally accepted non-invasive method of the assessment of the large artery compliance. However, the relationship between invasive and non-invasive measurements of the aortic compliance still requires investigation. The of the study was to assess the correlation between a proposed invasive method of aortic compliance evaluation and carotid-femoral pulse wave velocity. Methods: in a group of 25 patients (age 52.8 ± 9.1 years) with the diagnosis of ischaemic heart disease, intra-aortic blood pressure has been measured and pulse pressure calculated during elective, diagnostic heart catheterisation. A measurement of maximum change in the diameter of the descending aorta on the level of the aortic valve has been carried out as well. Aortic diameter change/pulse pressure ratio has been used as the aortic compliance index. In all patients carotid-femoral pulse wave velocity has been measured using Complior device. Results are presented in the table.

A negative correlation between pulse wave velocity and aortic diameter change/pulse pressure ratio has been observed (r = - 0.55, p < 0.05).
Calculation of a simple index of aortic diameter change/pulse pressure ratio during invasive heart examination can be provisionally accepted as useful in the evaluation of the aortic compliance. Further investigation is required to assess the diagnostic and prognostic value of this index especially.
