Echocardiographic parameters before and 8 wk after left descending coronary artery ligation

	Before Surgery	8 wk After Surgery
LVIDd, mm	7.8 ± 0.2	10.1 ± 0.1*
LVIDs, mm	4.6 ± 0.2	8.8 ± 0.2*
EDV, ml	1.04 ± 0.07	2.12 ± 0.06*
ESV, ml	0.24 ± 0.03	1.46 ± 0.10*
HW/BW, mg/g	2.9 ± 0.1	3.5 ± 0.2*
EF, %	77.3 ± 1.2	31.5 ± 3.4*

Data are means ± SE. LVIDd and LVIDs, left ventricular inner dimension at end diastole and systole; EDV, end-diastolic volume; ESV, end-systolic volume; HW/BW, heart weight-to-body weight ratio; EF, ejection fraction.

^*P < 0.05, compared with before surgery.
