Association of Hyperhomocysteinemia with Increased Coronary Microcirculatory Resistance and Poor Short-Term Prognosis of Patients with Acute Myocardial Infarction after Elective Percutaneous Coronary Intervention

Table 3

Comparison of cardiac function and the incidence of MACE after PCI between the two groups.

		HHcy (n = 53)	Control (n = 48)		X^2 (t)
LVEDd (mm)	1^st day after PCI	48.2 ± 3.7	47.3 ± 4.6	0.325	0.989
	3 months after PCI	52.3 ± 4.2	48.4 ± 4.6	0.000	4.410
	Difference	4.2 ± 2.0	1.1 ± 2.5	0.000	6.780
EF (%)	1st day after PCI	50.0 ± 7.4	52.1 ± 6.8	0.142	−1.479
	3 months after PCI	47.8 ± 6.4	54.7 ± 6.1	0.000	−5.535
	Difference	−2.2 ± 2.8	2.6 ± 2.9	0.000	−8.573
Total number of MACE		13 (24.5%)	3 (6.3%)	0.019	5.503

HHcy: high homocysteine; LVEDd: left ventricular end diastolic dimension; EF: ejection fraction; MACE: major adverse cardiovascular events.
