Study population
The study was approved by the Çanakkale Onsekiz Mart University Ethics
Committee and conformed to the principles outlined in the Declaration of
Helsinki. All subjects participating in the study gave informed consent.
The subjects who underwent either myocardial perfusion scintigraphy or
treadmill test for myocardial stress, were included in this prospective
study and the ones who had positive stresss test and scheduled for
coronary angiography were evaluated with STE.
All participants were initially evaluated by a standard
echocardiographic examination. Patients with previous myocardial
infarction, patients with acute coronary syndrome, moderate and severe
valve disease, cardiomyopathy, chronic systemic or inflammatory diseases
or any form of malignancy, and patients with previous thoracic surgery,
were excluded from the study.
Ventricular function was assessed by STE before the angiography and it
was compared with angiography results thereafter (Figure 1)
