Me thods 286 CHD patients, average age 63 16±11 21 years, male 171 case s and female 115 cases, were examined of left atrium diameter(LAD), left ventric ular systolic and diastolic diameter(LVS d and LVD d),septal thickness(IVST),l eft ventricular ejection fraction(EF),E/A ratio, resting heart rate(RHR), an d coronary arteriography. Res ults LAD and RHR were increased in CHD patients, and even more in CHD p atients with LVH.Correlation analysis showed that the LAD of CHD patients corre lated negatively to EF( P <0 05), and positively to the level of coronary artery s tenosis. Otherwise, LAD correlated positively to RHR in CHD patients. C onclusions Left atrium enlargment may be a mark of development of CHD a nd decrease of cardiac function.展开更多
