Ultrasonographic assessment of cardiac function and disease severity in coronary heart disease

Table 1 Comparison of ultrasonic parameters between two groups (mean ± SD)

Group	n	E/A	LVDd (mm)	LAD (mm)
Research group	106	1.46 ± 0.34	58.24 ± 5.05	43.31 ± 4.38
Control group	106	1.88 ± 0.44	48.15 ± 3.93	34.94 ± 2.81
t		7.776	16.234	16.560
P value		< 0.001	< 0.001	< 0.001

E/A: Early-to-late diastolic blood flow velocity ratio; LVDd: Left ventricular end-diastolic volume; LAD: Left atrial diameter.
