Pressure and microcirculatory effects of treatment with lercanidipine in hypertensive patients and in vascular patients with hypertension

The aim of this study was to evaluate the macrocirculatory and microcirculatory effects of treatment with lercanidipine, a new antihypertensive agent acting both on blood pressure and microcirculation in patients with moderate essential hypertension and without vascular disease and in patient with hypertension and vascular disease. In hypertensive subjects target-organ damage associated with high blood pressure may now be objectively documented by noninvasive tests. These alterations constitute a model to evaluate not only the pressure effects of antihypertensive treatment but also the normalization of the peripheral microcirculatory network. With color duplex scanning, flow velocity in the central retinal artery and retinal flow velocity can be measured and with use of laser-Doppler-flowmetry, it is also possible to evaluate microcirculation alterations in hypertensive subjects. These evaluation methods are completely noninvasive and may be used to assess the microcirculatory effects of antihypertensive drugs.
