title: [Emerging risk factors and prevention of atherosclerosis in uraemia].
abstract: A high rate of cardiovascular morbidity and mortality in uremic patients was documented early in the 1970s, and this remained unchanged according to more recent European and U.S. American registry report. In large cross-section studies of uremic patients, traditional cardiovascular risk factors such as hypertension and hypercholesterolemic have been found to have low predictive power, while emerging factors such as markers of inflammation and malnutrition, are strongly correlated with cardiovascular mortality. In addition, retained uremic solute such as b-2-microglobulin, advanced glycosylated end product (AGE), homocysteine, cysteine, sulfate may contribute to the pro-atherogenic milieu of uremia. Exhaled alkanes such as isoprene, increased during and after hemodialysis sessions, have been identified as accelerating factors of the atherosclerotic process. In patients with renal disease, even when GFR is still normal, increased sympathetic activity is demonstrable. The rising catecholamines turnover is a risk factor for cardiovascular disease for the high sensitivity of the heart and the arteries to increased sympthetic activity.
