摘要: Although there have been isolated reports of congestive heart failure (CHF) with normal systolic function, the prevalence and characteristics this condition not previously described. Accordingly, 188 patients CHF undergoing radionuclide ventriculography were prospectively evaluated. Sixty-seven (36%) had a ejection fraction (EF) 0.45 or greater, 121, an abnormal EF less than 0.45. Of these, 72 (55 [group I] 17 II]) also reviewed for clinical characteristics. There was no demographic difference between groups, except that systemic hypertension appeared to be contributing factor in 65% group II, compared 23% I (p
