Abstract

Reduced left ventricular diastolic filling (Df) has been noted in coronary disease (CD) patients with normal left ventricular systolic function (NLVF). However, previous studies have included patients with regional wall disease, hypertension, or left ventricular hypertrophy. In the absence of these factors, only a subgroup of patients who had >75% luminal obstruction of the left anterior descending artery (LAD) demonstrated DF abnormalities. Using 60 frames/sec biplane contrast ventriculography, we evaluated the left ventricular filling curve and its derivative in 21 patients with normal coronary arteries and NLVF (group 1), 17 CD patients with NLVF and no LAD disease (group 2), and 18 patients with LAD disease and NLVF (group 3). The peak filling rate (PFR) as end diastolic volumes/sec (EDV/S) was reduced in group 3 patients (group 3: 3.00 ± 0.51 EDV/S vs group 1: 3.59 ± 0.84 EDV/S, p <.05; and group 2: 3.61 ± 0.91 EDV/S, p <.05). There was marked overlap in the Pfr's between the normal and LAD group. DF may be normal in CD patients with NLVF in the absence of LAD disease. LAD patients have abnormal DF, but these abnormalities lack predictive valve.
