cial effects on cardiac function.

It has been shown, however,
that myocardial performance improves gradually after PCI,
24
so
we are hopeful that further improvements in myocardial function
will be achieved over time following successful PCI.
A limitation to the current study could have been the rela-
tively small number of patients evaluated. Moreover, since
functional improvement following PCI may increase over time,
24
early assessment of myocardial performance could be another
limitation of this study. The final shortcoming may have been
the fact that we did not consider clinical improvement along with
echocardiographic parameters. To our knowledge, this study is,
however, the first to cover a wide range of echocardiographic
indices for post-PCI functional assessment in patients with stable
CAD.
Conclusion
Unlike studies that showed an improvement in TDI parameters
of systolic and diastolic function in patients with stable CAD
after successful PCI, in our population only the colour M-mode
Doppler parameter improved 48 hours after successful elective
PCI in patients with stable CAD. More studies should be done to
corroborate the results presented here.
