Cardiac hemodynamics and coronary arterial injury. A: pressure-volume loop shows normal and overloaded pressure induced by aortic constriction. B: left ventricle (LV) fractional shortening of echocardiography in different groups. **P < 0.01 compared with control. C: correlation between LV fractional shortening and LCA injured length. Injured length = lost branch/LCA in MI-1m, I/R-1m and ischemic bare branch/LCA in Ab+I/R+DeAb hearts (R² = 0.62, P < 0.01). D: ratio of casted coronary artery (CA) weight and body weight (BW) in different groups. **P < 0.01 compared with control, MI-1m; and P < 0.05 compared with I/R-1m.
