dc.description.abstractEjection phase indices of left ventricular performance are standard parameters
for the evaluation of myocardial contractility. Recently, ejection fraction and ejection rate are
easily obtained from radionuclide gated cardiac blood pool scan. No method, however, is
available for determining the mean circumferential fiber shortening rate (Vcf) precisely. Velocity
indices are relatively independent of alternation in resting filling pressure and volume, and
responsive to changes in heart rate. We measured the left ventricular mean circumferential fiber
shortening velocity using gamma camera interfaced to a computer after injection of radionuclide
to evaluate its significance for detecting left ventricular dysfunction, especially in patients
With coronary heart disease. Radionuclide-determined values for mean fiber shortening rate
correlated (r=0.79) with values for this index obtained from echocardiography. Left ventricular
ejection fraction correlated with mean fiber shortening rate. There was a strong relationship
between the value of mean fiber shortening rate and the severity of myocardial impairment by
the NYHA(New York Heart Association) functional class (r=0.84).
In summary, these data indicate that gated cardiac blood pool scan provides a noninvasive,
accurate and simple method to measure the mean circumferential fiber shortening rate and it
can be utilized in a variety of cardiac disorders.
