摘要
目的探讨核磁共振成像(MRI)与二维超声心动图评价冠心病心功能及其与纽约心脏病协会(NYHA)分级的关系。方法回顾性分析我院2017年5月至2019年6月收治的90例冠心病患者的临床资料,按照NYHA分级不同分为心功能Ⅰ~Ⅱ级组(21例)、心功能Ⅲ级组(37例)、心功能Ⅳ级组(32例),比较三组患者MR、二维超声心动图检查心功能结果 ,并分析MRI、二维超声心动图检查结果与NYHA分级的关系。结果 MRI检查结果显示,三组左心室射血分数(LVEF)随着NYHA分级的增加而减小,心功能Ⅳ级组<心功能Ⅲ级组<心功能Ⅰ~Ⅱ级组(P<0.05);三组左心室收缩末期容积(LVESV)、左心室舒张末期容积(LVEDV)随着NYHA分级的增加而增大,心功能Ⅰ~Ⅱ级组<心功能Ⅲ级组<心功能Ⅳ级组(P<0.05)。二维超声心动图检查结果显示,三组LVEF随着NYHA分级的增加而减小,心功能Ⅳ级组<心功能Ⅲ级组<心功能Ⅰ~Ⅱ级组(P<0.05);心功能Ⅲ、Ⅳ级组LVESV、LVEDV均大于心功能Ⅰ~Ⅱ级组(P<0.05);心功能Ⅲ级组、Ⅳ级组LVESV、LVEDV的比较,差异无统计学意义(P>0.05)。经Spearman相关性分析结果显示,MRI、二维超声心动图检查心功能结果 LVEF与NYHA分级为负相关,LVESV、LVEDV与NYHA分级为正相关。结论 MRI与二维超声心动图评价冠心病心功能均与NYHA分级的相关性良好,但MRI优于二维超声心动图。
Objective To explore the relationship between cardiac function and grading of New York Heart Association(NYHA) in patients with coronary heart disease(CHD) evaluated by magnetic resonance imaging(MRI) and two-dimensional echocardiogram(2 D-ECG).Methods The clinical data of 90 CHD patients in the hospital from May 2017 to June 2019 were retrospectively analyzed.According to different NYHA grading,they were divided into cardiac function Ⅰ-Ⅱ group(21 cases),cardiac functionⅢ group(37 cases),cardiac function IV group(32 cases).The examination results of cardiac function by MRI and 2 D-ECG were compared among the three groups.The relationship between examination results of M RI,2 D-ECG,and NYHA grading was analyzed.Results M RI examination results showed that left ventricular ejection fraction(LVEF) in the three groups was decreased with the increase of NYHA gra ding.Arranging LVEF from low to high,the corresponding order was cardiac function IV group,cardiac function Ⅲ group and cardiac function Ⅰ-Ⅱ group(P<0.05).The left ventricular end-systolic volume(LVESV) and left ventricular end-diastolic volume(LVEDV) in the three groups were increased with increase of NYHA grading.Arranging LVESV and LVEDV from low to high,the corresponding order was cardiac function Ⅰ-Ⅱ group,cardiac function Ⅲ grou p,and cardiac function IV group(P<0.05).The examination results of 2 D-ECG showed that LVEF in the three groups was decreased with the increase of NYHA grading.Arranging LVEF from low to high,the corresponding order was cardiac fu nction IV group,cardiac function Ⅲ,and cardiac function Ⅰ-Ⅱ group(P<0.05).LVESV and LVEDV in the cardiac function Ⅲ and cardiac function IV groups were more extensive than those in the Ⅰ-Ⅱgroup(P<0.05).There was no significant difference in LVESV or LVEDV between cardiac function Ⅲand cardiac function IV groups(P>0.05).The results of Spearman correlation analysis showed that LVEF was negatively correlated with NYHA grading,while LVESV and LVEDV were positively correlated with NYHA grading.Conclusion Both MRI and 2 D-ECG are good at evaluating the correlation between cardiac function and NYHA grading in CHD patients.However,MRI is better than 2 D-ECG.
