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.
