RESULTS
50 patients were recruited in our study. The general characteristics of
the study population depicted in table 1. Echocardiographic findings of
the study population were in normal range. Conventional echocardiography
parameters shown in table 2. 38 patients had severe CAD
(>50%) whilst 12 patients had no significant CAD. PSS was
significantly related with CAD and area at risk in all echo planes.
(p<0.0001) LV wall analysis of PSS according to the coronary
occlusion was showed in Table 3. In the segmental PSS analysis, the
presence of PSS in the basal anterior and mid anterior segments was
found to be significantly associated with left anterior descending
artery (LAD) stenosis, respectively p<0.001,
p<0.001. The presence of PSS in the basal lateral wall was
found to be significantly associated with circumflex (LCX) stenosis,
p=0.032. The presence of PSS in the basal inferior wall was found to be
significantly associated with right coronary artery (RCA) stenosis,
p=0.021. Detailed segmental analysis of PSS according to the coronary
artery stenosis was showed in supplementary table 1. The relationship of
PLS with the area at risk was found to be statistically insignificant
whereas GLS was significantly lower in patients with severe CAD
(p=0.011). LV wall analysis of PSS according to the coronary occlusion
was showed in Table 4. The presence of PSS was not associated with the
coronary stenosis in segmental PLS analysis. Detailed segmental analysis
of PSS according to the coronary artery stenosis was showed in
supplementary table 2.
