We estimated the magnitude of the left atrial contraction in 28 patients with ischemic heart disease by calculating the biplane cineangiographic volumes of the left atrium. The left atrial contraction contribution to the left ventricular stroke volume (ml/m2, Y axis) correlated inversely with the left ventricular ejection fraction (%, X axis), yielding an equation: Y = -0.31X + 43.7 (n = 28, r = -0.56, p less than 0.001). The result indicates that the left ventricular filling is compensated by… CONTINUE READING
