BACKGROUND: With aging lipid parameters tend to modify. This represents a risk factor which is useful to monitor in Primary Practice. Arterial elasticity represents the opposite of the arterial stiffness. It shows how elasticity decreases with age. Research question: Can we establish a correlation between lipid parameters and the arterial stiffness in hypertensive persons? METHOD: We selected 120 hypertensive individuals aged 40 to 80 years. Cases with secondary hypertension were not included in the study. Lipid parameters of these individuals were measured using the Guideline for the Management of Hypertension (European Society of Cardiology / European Society of Hypertension). Pulse Wave Velocity (PWV) of the aorta has also been measured (as the gold standard for arterial rigidity) using an Arteriograph (Medexpert). We tried to establish a correlation between lipid parameters and PWV. RESULTS: We found the following results: A) The PWV=9.29m/s, Standard Deviation (SD) = +/-1.94) and Total Cholesterol (TC) = 209mg/dl SD=+/-48.2, correlate linearly with Pearson index r=0.481. B) PWV=9.29m/s and LDL cholesterol (LDLc)=116mg/dl +/-49.8, correlate linearly with Pearson index r=0.505. C) Triglycerides (TG) = 148mg/dl SD=+/-121 and PWV correlate linearly with Pearson index r=0.389, D) Also HDL cholesterol (HDLc) =48.1mg/dl SD=+/-12.9 and PWV negatively correlate with a Pearson index r= - 0.354. CONCLUSIONS: Evaluating aortic stiffness and lipid parameters are useful in the evaluation of hypertensive patients with cardiovascular risk. Arterial stiffness measured using with an Arteriograph directly correlates with TC, LDLc and indirectly with HDLc. Keywords: Lipid parameters, elasticity of great arteries, hypertensive patients.
