摘要
目的探讨冠心患者病左心室舒张功能对左心房内径的影响。方法选择行冠状动脉造影并测定左心室舒张末压（LEVDP）的住院患者355例，根据冠状动脉造影结果分为非冠心病组（214例）和冠心病组（141例），再根据LEVDP将冠心病组分为LEVDP正常组[LEVDP〈15mmHg（1mmHg=0．133kPa），37例]、轻度升高组（LEVDP15～30mmHg，65例）和明显升高组（LEVDP≥30mmHg，39例），比较左心房内径在各组之间的差异。结果非冠心病组左心房内径为（28．04-3．2）mm；冠心病组左心房内径平均为（38．0±2．2）mm，其中LEVDP正常组为（29．1±4．1）mm，LEVDP轻度升高组和明显升高组分别为（35．6±3．5）、（41．4±3．2）mm。LEVDP轻度升高及明显升高组患者左心房内径明显高于非冠心病组和LEVDP正常组（均P〈0．01），LEVDP明显升高组左心房内径明显高于LEVDP轻度升高组（P〈0．01）。LEVDP与左心房内径呈正相关（r=0．91，P〈0．01）。结论冠心病患者左心房内径随LEVDP增高而逐渐增大。
Objective To explore the relationship between elevated left ventricular end-diastolic pressure （LEVDP） and left atrium diameter （LAD）. Methods All 355 inpatients receiving LEVDP and coronary angiography（CAG） measurements were divided into coronary heart disease（CHD） group（ 141 cases） and non-CHD group（214 cases）. CHD group was divided into 3 subgroups： [ LEVDP 0-15 mm Hg（ 1 mm Hg = 0. 133 kPa）, LEVDP 15-30 mm Hg and LEVDP≥30 mm Hg groups]. The LAD was compared among 4 groups. Results The LAD levels were （28.0± 3.2）mm, （38.0 ±2.2）mm, （29.1±4.1）mm, （35.6 ±3.5）mm and（41.4 ±3.2）mm in non-CHD group, CHD group, LEVDP 0-15 mm Hg group, LEVDP 15-30 mm Hg group and LEVDP≥30 mm Hg group; LAD levels in LEVDP 15-30 mm Hg group and LEVDP≥30 mm Hg group were higher than those in non- CHD group and CHD group （P 〈0.01 ） ; LAD level in LEVDP≥30 mm Hg group was higher than that in LEVDP 15-30 mm Hg group （ P 〈 0.01 ）. LAD and LEVDP had a positive correlation （ r = 0.91, P 〈 0.01 ）. Conclusion LAD of patients with CHD elevates with the increasing of LEVDP.
