Feasibility and reliability of ankle/arm blood pressure index in preventive medicine.

Despite its potential usefulness for assessing preclinical atherosclerosis and cardiovascular risk, the ankle/arm blood pressure index (AAI) has not yet been the matter of study evaluating its feasibility and reliability by nonspecialist doctors in a general population. This study was planned for two steps. In step 1, the measurement of AAI, (ratio between Doppler systolic pressure at the ankle for each lower limb and the highest value of Doppler systolic pressure of the two upper limbs), should be performed by 50 general practitioners (GPs), 50 social security center physicians, and 50 occupational health physicians in 3,000 male smokers, 40 to 59 years, without clinical cardiovascular disease.

Aortic stiffening does not predict coronary and extracoronary atherosclerosis in asymptomatic men at risk for cardiovascular disease.

Stiffness of aortic walls has been shown to be a marker of coronary and cerebrovascular diseases in patients with myocardial infarction or stroke. However, its value for predicting preclinical atherosclerosis has not been demonstrated. Therefore, this study tested the association of aortic wall stiffness and coronary and extracoronary atherosclerosis in the absence of clinical cardiovascular disease.

Cholesterol lowering therapy inhibits the low-flow mediated vasoconstriction of the brachial artery in hypercholesterolaemic subjects.

1. We tested whether lipid lowering treatment with HMG CoA reductase inhibitor modified the flow mediated large artery reactivity in primary pure hypercholesterolaemia. 2.

Echographic assessment of carotid and femoral arterial structure in men with essential hypertension. Group PCVMETRA.

Extracoronary in vivo structural arterial changes were studied in asymptomatic essential hypertension. Carotid and femoral arteries were examined with B-mode echography for the presence or absence of plaque (the whole vascular segments of each vessel in the both sides) and for automated measurement of the far wall intima-media thickness (the vascular segment of each vessel proximal to the bifurcation in the right side) in 53 never treated hypertensive men and 133 normotensive men similar with regard to age, serum cholesterol levels, and smoking history. In the hypertensive group carotid plaque was more frequent (P < .

Role of blood pressure, uric acid, and hemorheological parameters on plasma homocyst(e)ine concentration.

Elevated concentration of plasma homocyst(e)ine is an independent risk factor for clinical atherosclerosis. In this study, the concentration of plasma homocyst(e)ine in men who lacked a history of atherosclerotic disease was correlated with hemodynamic, rheological and biochemical parameters. Hypertensive subjects had higher concentrations of plasma homocyst(e)ine than normotensive subjects.
