Full textThe main objective in this work is to identify the determinants of preclinical target organ damages in hypertension in a cohort of 1500 nevertreated normotensive and hypertensive subjects. Renal hemodynamic was evaluated by measurement of glomerular filtration rate (GFR) and renal plasma flow (RPF) using isotopic techniques. Left ventricle (LV) morphology and function were studied by echocardiography. In a cross-sectional analysis, it was found that the age associated decline in GFR was steeper in hypertensive subjects with LV concentric hypertrophy or remodeling, showing the link between cardiac and renal damages. In normotensives, blood pressure (BP), despite its low range, was directly related with GFR and LV mass. The follow-up of a group of untreated subjects confirmed that BP was the main determinant for LV mass progression and decline in renal function. When considering the different components of BP, it was shown that pulse pressure was the most powerful correlate of decline in GFR and RPF in hypertensive subjects during treatment. Study of large arterial function in normotensive subjects suggested in a cross-sectional analysis that wave reflection but not arterial stiffness could modulate intraglomerular pressure as reflection magnitude was directly related to filtration fraction and albuminuria. Long-term follow-up is necessary is order to confirm this interaction between the renal microcirculation and the macrocirculation

Full textAgeing of the aorta involves degenerative remodeling with medial elastocalcinotic arteriosclerosis leading to increased wall stiffness, increased pulse pressure and upstream and downstream target-organ damage ("stiff vessel disease", SVD). Using a rat model of the above phenomena (hypervitaminosis D plus nicotine, VDN), we investigated, firstly, the etiology of this process and, secondly, target-organ damage (kidney). We observed that, in the VDN rat, medial elastocalcinosis involves inflammation of the aortic wall. This can be attenuated by treatment with pioglitazone, an activator of PPARγ. The latter may represent a drug target for the treatment of SVD. In the second part of this thesis, we showed that three months of exposure to hyperpulsatility, in VDN rats, lead to renal function alteration, suggesting that central arterial hyperpulsatility induced by SVD can produce target organ damage downstream

Full textThe combined treatment of risk factors, in particular hypertension and diabetes, appears insufficient to achieve substantial reduction in cardiovascular (CV) morbidity and mortality. This residual risk may be indicative of adverse responses of subclinical arterial damage, illustrated by aortic stiffness and pressure wave reflection. These hemodynamic parameters are considered to be associated with central pulse pressure level. Central blood pressure appears closely related to the developpment and complications of atherosclerosis as well as microvascular organ damage. Firstly, the objective of this work was to study subclinical arterial damage by noninvasive measurement of aortic stiffness and pressure wave reflection, and their determinants, in two cohort of patients with increased CV risk, hypertensive and/or diabetic patients and patients with HIV infection. In a third cohort, composed of patients with type 2 diabetes, we studied aortic stiffness as a independant maker of CV disease. Secondly, we investigate whether noninvasive aortic stiffness assessment improves diagnostic accuracy of coronary artery disease (CAD) screnning. The contribution of aortic stiffness in improving the detection of CAD was studied as part of a complete CV evaluation. The main conclusion of this work is that assessment of subclinical arterial damage provides a clinically useful tool to individualize high-risk patients and to improve CAD screening. Prospective evaluation of aortic stiffness and central pulse pressure in parallel with incidence of CV events would clarify the importance of these hemodynamic parameters in the management of the residual risk
