Introduction: Wave velocity of pulse (WVP) is emerging as a clinical marker of risk of cardiovascular events and correlates with the degree of arterial stiffness. There are several methods proposed as Doppler evaluation and by means of tonometry with inflatable cuff, both validated with hemodynamic study. The hypothesis is to evaluate the correlation between both methods and with the cardiovascular risk factors to assess their use in daily practiceMaterial and Methods: A total of 100 consecutive patients were presented to perform echo stress for diagnosis and/or prognosis of coronary disease. Doppler of left carotid and ipsilateral common femoral was performed, measuring the time difference of QRS start of the electrocardiogram and the spectral Dopler wave foot divided by the site distances of both measurements. On the other hand, the WVP was measured simultaneously by the Arteriograph cuff in the left arm according to international standards.Results: The average age was 63.08 years (40-81), 65 men (65%) and 35 women (35%). 29% of the population was diabetic, 49% overweight or obesity, 21% with previous myocardial infarction, 27% some type of revascularization, 9% active smoker and 33% ex-smokers, 44% were dyslipidemic, 45% of total medicated. WVP by Doppler could be measured in 99% of the cases and 93% with the Arteriograph, having a positive correlation coefficient between both of 0.25. The correlation between WVP by Doppler and presence of hypertension was 0.64, while by Arteriograph it was 0.21. The correlation between any of the methods with diabetes, acv, obesity and ischemic heart disease gave neutral correlation.Conclusions: WVP is a marker of arterial health and it is feasible to measure it by different methods, in this case in most of them. For patients with hypertension the WVP by doppler method showed a slight positive correlation, being superior to the Arteriographic method.
