Abstract
Objective To investigate the relationship between coronary artery lesion and cardiac function in coronary atherosclerotic heart disease (CHD) patients.Methods Ninty cases of patients with CHD who were hospitalized for chest pain in Air Force PLA General Hospital and scheduled for coronary angiography were selected.Noninvasive hemodynamie testing was performed before coronary angiography.According to the results of coronary angiography,74 patients with coronary artery stenosis were selected as disease group,persons with an additional angiography showed no coronary artery stenosis and excluded from other systemic diseases in physical examination center(30 cases) were chosed as control group.According to the results of coronary angiography,the Gensini score system was used to quantify the degree of coronary artery disease,the patients were divided into two groups according to the score.:high score group (Gensini score＞ 20 points,40 cases) and low score group (Gensini score≤20).And the relationship between coronary artery stenosis and cardiac function was analyzed by comparing the two groups of noninvasive hemodynamics cardiac function indexes,BNP and LVEF values.Results The levels of C,SV,CO,CI,HI and LVEF in the disease group were significantly lower than those in the control group (P＜0.05),Q-B/B-X was significantly higher than that in the control group (P＜0.05);There were statistically significant of BNP and LVEF between Gensini high score and low score group (P＜0.05).The Pearson correlation analysis showed there was significantly negatively correlated between Gensini score and C,SV,CO,CI,HI,LVEF,and significantly positively correlated btween Gensini score and Q-B/B-X,BNP.Conclusion The degree of coronary artery lesion was negatively correlated with cardiac function,and the worse the disease,the worse the heart function.关键词
