Relationship between Cardiac Function and NYHA Grading in Coronary Heart Disease Patients Evaluated by MRI and Two-dimensional Echocardiogram

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.
