Congestive heart failure caused by abnormal diastolic function may be
far more common than previously recognized. The diastolic disorder mus
t be distinguished from systolic abnormalities because treatment is si
gnificantly different. Although prognosis is better with diastolic dys
function than with systolic dysfunction, mortality and morbidity conti
nue to be high in elderly patients. Drs Spencer and Lang describe the
mechanisms, symptoms, diagnosis, and management of diastolic heart fai
lure.
