Abstract |
We performed exercise radionuclide ventriculography to
evaluate left ventricular (LV) function in 35 patients
with pure mitral stenosis (MS). There were 6 males and
29 females ranging from 21 to 63 years of age (mean
37¡¾10 years). We also studied 8 healthy men as
control group (mean age 27¡¾5 years. Each patients
was evaluated at rest and during maximal exercise on an
isokinetic bicycle ergometer. Peak filling rate (PFR),
peak ejection rate (PER), ejection fracion (EF), end-
diastolic volume(EDV), end-systolic volume (ESV),
stroke volume (SV), and cardiac output (CO) were
determined by the radionuclide technique. The results
were summarized as follows: 1) LV systolic dysfunction
and reduced PFR were noted in patients with MS. 2) EDV
as well as SV decreased with exercise in patients with
MS. 3) No significant increase in EF during exercise
compared to rest value was observed because it was
caused by reduced EDV and SV during exercise in
patients with MS. 4) CO increased with exercise was
significantly lower than normal in patients with MS. 5)
Patients with MS were divided into two groups according
to whether EF increased more than 5% druing exercise
compared to resting state or decreased. Significant
difference were found between these two groups.
Patients with a fall in EF with exercise were older,
had larger left atrial size, and had lesser decreased
in ESV during exercise. |
