Abstract
Dilated cardiomyopathy DCM is a syndrome characterized by cardiac enlargment and impaired systolic function ()f one or both ventricles. The earliest abnormality usually is ventricular enlargement and systolic controctile dyafunation, with congestive heart filure often developing later. Large arteries sllch as the carotid.. conomay and renal arteries aretraditionaly thougt of as passire conduit whose principal function is to conduct and distribute cardiac autuput to various tissues. Conduit artevies represent a loue resistance system that is not thought to be involved with blood flow regulation In addition to their contuit function, large ateries have a buffering fubction causing the phasic flow of cardiac output to tranolated into a continous flow at the peripheral level. In this regard, the viscoelastic properties- of the arterial wall play an important nor enablimg part of the shoke VOlU111e to be atored in the arterial wall during systole and to flow toward the periphery during diastole. The present study was carried to determine whether arterial distensibilty is reduced in patients with CHF and detdrmined whether decreased arterial compliance is related top an abnormality in vascular wall structue. The present study included 30 patients with CHF due to dilated cardiomyopathy.
