Table 3. Association between significant drop (greater than 10%) in left ventricular ejection fraction (LVEF) and the presence of significant decrease in longitudinal peak systolic strain (> 15%) measured globally and various regions of the left ventricle .

Parameter	No change in LVEF (n=52)	Drop in LVEF>10% (n=11)	Odds ratio (95% CI)	P value
Global stress ≥15%	5 (9.6%)	3 (27.3%)	3.53 (0.70–17.74)	0.137
Regional stress ≥ 15%
Apical region	12 (23.1%)	6 (54.5%)	4.00 (1.04–15.44)	0.062
Mid-papillary region	7 (13.5%)	3 (27.3%)	2.41 (0.51–11.33)	0.360
Basal region	13 (25.0%)	4 (36.4%)	1.71 (0.43–6.81)	0.469
