Evolution of left ventricular function among subjects with ST-elevation myocardial infarction after percutaneous coronary intervention

Table 2 Evolution of myocardial infarction size and left ventricular function

Culprit vessel	Infarct size %		Ejection fraction % Controls 60 ± 5		Mean AVPD (mm) Controls 15 ± 2
Culprit vessel	Sub-acute	Chronic	Sub-acute	Chronic	Sub-acute	Chronic
All (n = 77)	17 ± 10	10 ± 6 †††	48 ± 8***	52 ± 9***,†††	12 ± 2***	13 ± 2***,†††
LAD (n = 28)	24 ± 8	14 ± 6 †††	45 ± 9***	49 ± 11***,†	11 ± 2***	13 ± 2***,†††
RCA (n = 39)	14 ± 8	9 ± 5 †††	51 ± 7**	54 ± 8**,†	12 ± 2***	13 ± 3***,††

Left anterior descending = LAD. Right coronary artery = RCA. Left circumflex = LCx. AVPD = atrioventricular plane displacement
Comparison between patients and controls; ** = p < 0.01 *** = p < 0.001
Comparison between sub-acute and chronic phases: † = p < 0.04 †† = p < 0.01 ††† = p < 0.001
