e0496 Comparative study of impaired with normal left ventricle function patients with triple coronary artery disease

Background Ischaemic cardiomyopathy is one of the fatal courses of coronary heart disease, its clinical characteristics and percutaneous coronary intervention (PCI) effect on it still need to be identified. Methods From April 2004 to April 2007, 4494 consecutive patients with triple coronary arteries disease identified by coronary angiogram (>70% stenosis of each vessel) in our center were divided into two groups according to left ventricle ejection fraction (LVEF) (N group: n=4129, LVEF>40%; L group: n=365, LVEF≤40%). Results Patients in L group was younger (60.6±9.72 vs 65.2±10.7 years; p Conclusion This one center, large sample study showed clinical characteristics of ischaemic cardiomyopathy, MI and diabetes might contribute to its morbidity, and PCI might prevent its morbidity. PCI of patients with triple coronary arteries disease and impaired left ventricle (LV) function leaded to worse outcomes when compared with normal LV function.
