Abstract:
Objective:To analyze the relationship between the left atrioventricular (AR) interval of patients with coronary heart disease (CHD) measured by electrocardiogram and the patients′ condition, cardiac color Doppler ultrasound and coronary artery lesions.Methods:The CHD patients undergoing esophageal ECG examination in Yantai Mountain Hospital from June 2018 to April 2020 are divided into three groups according to the AR interval: AR interval <100ms, AR interval 100 to 150 ms, and AR interval>150 ms; The general data, condition, cardiac color Doppler ultrasound and coronary artery lesions indicators of the three groups were compared. Disorderly multiple Logistic regression was used to analyze the relationship between coronary heart disease AR interval and condition, cardiac color Doppler ultrasound and coronary artery lesions indicators.Results:There were no statistical difference in gender, age, diabetes, smoking history, blood lipids, blood uric acid (UA) and diastolic blood pressure (DBP) among 3 groups ( P>0.05); but there were statistical differences in proportion of hypertension, systolic blood pressure (SBP), CHADS2 score, CHADS2 -VASc score and Gensini score among 3 groups: 54.72% (29/53), 31.25% (20/64) and 46.81% (35/72); (138.84 ± 4.97), (122.47 ± 7.45) and (139.23 ± 7.05) mmHg (1 mmHg = 0.133 kPa); (1.47 ± 0.08), (1.02 ± 0.15) and (1.67 ± 0.10) scores; (1.49 ± 0.28), (1.00 ± 0.24) and (1.74 ± 0.22) scores; (38.27 ± 5.84), (24.45 ± 6.08) and (39.42 ± 5.71) scores, P<0.05. There was no statistical difference in stroke volume (SV) among 3 groups ( P>0.05), but there were statistical differences in the incidence of AP, incidence of AMI, left ventricular end -diastolic volume (LVEDV), left ventricular end -systolic volume (LVESV), left ventricular ejection fraction (LVEF), the ratio of early diastolic mitral valve blood flow velocity to late diastolic mitral valve blood flow velocity (E/A) and single branch/ double branches/ ≥3 branches lesions of coronary artery: 41.51% (22/53), 65.62% (42/64) and 37.50% (27/72); 58.49% (31/53), 34.38% (22/64) and 62.50% (45/72); (150.73 ± 15.09), (141.49 ± 28.68) and (151.49 ± 14.47) ml; (42.15 ± 10.49), (39.82 ± 8.37) and (40.94 ± 11.02) ml; (56.27 ± 4.94)%, (62.20 ± 3.69)% and (57.64 ± 4.99)%; 0.98 ± 0.29, 1.22 ± 0.35 and 0.97 ± 0.34); 14/18/21, 37/13/14 and 9/22/41, P<0.05. Disorderly multiple Logistic regression analysis showed hypertension, AMI, LVEDV, LVESV, LVEF, Gensini score, coronary artery double branches lesions and ≥3 branches lesions of coronary artery were significantly associated with the AR interval of coronary heart lesions ( OR = 2.349, 1.893, 2.754, 2.872, 0.414, 2.201, 4.336 and 3.401; P<0.05). Conclusions:The AR interval of coronary heart disease is closely related to the condition, cardiac color Doppler ultrasound and coronary artery lesions indicators, which deserves clinical attention.
