Abstract

Introduction. The asynchrony of the left ventricle - ie. its nonuniform contraction and relaxation - is an important factor for left ventricular function. Heart failure is often related to abnormal systolic function, sometimes associated with a diastolic dysfunction. We studied the relationship of left ventricular asynchrony to left ventricular function in patients with nonischemic heart failure. Material and methods. Radionuclide angiography at rest was performed in 25 patients with nonischemic heart failure and in 26 age and sex matched normal subjects. In addition to ejection fraction and peak filling rate, two indices of left ventricular asynchrony were calculated: the coefficient of variation of regional time to end systole and the coefficient of variation of regional time to peak filling rate. These factors indicate how disperse are the regional values of time to end systole and of time to peak filling rate. In fact, the higher the value, the greater the asynchrony. Results. A significant (r=.46, p
